Old Fashioned Caramel Icing

While you might have heard about shortcuts to making caramel icing, there is a reason that it’s been made for generations using two spoons (one for the saucepan and one for the cast iron skillet): this icing may be the best you’ve ever tried.

Making it the old fashioned southern way takes time, and it’s totally worth the effort.

Be thankful that it takes about an hour to make – if it didn’t, you’d be making it and eating it way too often!

If you’re like me, gazing into a pot and repetitively stirring will hypnotize you. You’ll soon find yourself simply staring into the sweet confection, monitoring the reading on your candy thermometer as it crawls up, and observing the thickening icing with wide-eyed wonder.

Equipment and Ingredients

You will need a candy thermometer to properly make this icing! While you can try to gauge its temperature without one, you may end up burning the caramel and you’ll then have to throw it all away.

To make this recipe, you’ll also need two pans – a saucepan and a skillet.

Aside from the thermometer, the recipe requires only four ingredients that you may already have in your pantry – butter, evaporated milk, sugar, and vanilla extract.

How It’s Made

Start by melting two cups of sugar with butter and evaporated milk in a saucepan over medium heat. Periodically stir it to make sure everything is combining nicely.

Once the sugar is melted, reduce the heat to low.

Important: Do not let this mixture come to a boil.

Next, you’ll need to caramelize sugar in a cast iron or other heavy-bottomed skillet. Put the skillet on medium-low heat, add the remaining 1/2 cup of sugar, and push the sugar around periodically to make sure it heats evenly.

After a few minutes, you’ll notice that it will crystallize and clump up. Don’t stop stirring.

This is supposed to happen. Keep on stirring.

Eventually, after ten minutes or so, the sugar will melt down to a beautiful golden brown liquid.

Do not rush this icing. If you raise the heat to make things go faster, you risk burning the sugar and having to start all over.

Once the sugar is melted, bring the heat in the saucepan back up to medium-low.

Very carefully pour the caramelized sugar into the saucepan. It will bubble and steam like crazy. Stir immediately!

Then, keep on stirring. Stir and stir and stir until the mixture reaches 235 F (the soft ball stage) on your candy thermometer. This will take about thirty minutes.

If you don’t have a candy thermometer, you can test by dropping a small amount of caramel into water to see if it forms a soft ball (hence the name). However, it’s easy to miss the correct moment to do the test and your icing can be ruined.

Remove the saucepan from the heat immediately, stir in vanilla extract, and allow to cool for fifteen minutes before using it.

Expert Tips and FAQs

Caramel icing is not the same as smooth, sticky caramel that you would find in a candy bar or on a caramel apple. This is meant for frosting cakes and cupcakes. it’s a little crunchy (gritty) on the outside yet soft and smooth when you bite into it.

Hard and smooth caramel icing on a cupcake

This recipe is also quite different from caramel frosting. While the lines are somewhat blurred between frosting and icing (sometimes the terms are used interchangeably), typically an icing is considered a topping that is hard and flat while a frosting has height and is light and fluffy.

Slow Cooker Dulce de Leche
Don’t confuse this dulce de leche with the icing in this post. While delicious, dulce de leche will never form a hard crust!

If you are looking for the easiest possible way to make caramel sauce, I suggest you try using dulce de leche. Dulce de leche is a magical caramel-like spread that can be made simply by putting a can of sweetened condensed milk in a slow cooker! It doesn’t get much easier than that recipe and it’s still really, really tasty.

Note that dulce de leche will have a smooth texture and will not harden up like this recipe.

How do you recommend I use this icing?

After you’ve waited for the icing to cool slightly, dip cupcakes or cookies into it (or spread the icing on top) or pour or spread over cake. If you wait too long, the icing will harden and you won’t be able to spread it.

How long should I wait for the icing to harden?

Once the icing is on your baked goods, wait three to four hours for it to harden completely.

Which desserts do you recommend I use this on?

I love using this caramel icing on my caramel cupcakes. It’s also amazing on vanilla cupcakes or chocolate cupcakes! Try it on a pound cake or spread it on sugar cookies. Finally, for a fantastic sweet and salty option, try spreading it on Ritz crackers!

My icing cooled too much and it’s not pouring/spreading properly. Can I save it?

Yes! If the icing becomes too hard, you can reheat it by putting it back on the stove and heating it at medium-low heat, stirring until it is melted again.

Can This Icing Be Made Ahead?

In order to spread this icing on cake or cupcakes, it needs to be warm. If you are making it ahead of time, you can leave it at room temperature until ready to use (I would leave it out for several days, but I’m not a food safety specialist). Then, warm on medium-low heat in a saucepan, stirring until smooth before using.

Equipment

  • Candy thermometer

Ingredients

  • 1/2 cup unsalted butter
  • 3/4 cup evaporated milk
  • 2 1/2 cups granulated sugar divided
  • 1/2 teaspoon vanilla extract

Instructions

  • In a medium-sized saucepan over medium heat, mix butter, evaporated milk and two cups of sugar.
  • Heat and stir until sugar dissolves. Do not allow to come to a boil.
  • Once sugar dissolves, reduce heat to low.
  • In a small cast iron skillet on medium-low heat, melt the remaining half cup of sugar – stirring constantly until liquid and brown. (The sugar will crystallize about halfway through the process. Just keep stirring until it completely melts.)
  • Pour the browned sugar into the saucepan and quickly stir to incorporate. (It will bubble and steam. This is totally normal.)
  • Stir regularly until the liquid reaches the soft ball stage, 235 F (113 C). It’s easiest to check for the soft ball stage with a candy thermometer (the caramel should be about 235 F). If you don’t have a candy thermometer, you can test by dropping a small amount of caramel into water to see if it forms a soft ball (hence the name). It may take up to thirty minutes to reach the soft ball stage. Here’s where the patience kicks in. Resist the temptation to turn up the heat because the caramel can easily burn.
  • Remove from the heat and stir in the vanilla.
  • Wait ten to fifteen minutes and then dip, spread, or pour on your favorite baked goods.
  • Once the icing is on your baked goods, wait three to four hours for it to harden completely. 

Notes

Do not expect this recipe to produce a flowy/chewy caramel such as one you would find in a candy bar or a caramel apple. This is meant for frosting cakes and cupcakes and the icing is a little crunchy (gritty) on the outside but soft and smooth when you bite into it.
If the icing becomes too hard, you can reheat it by putting it back on the stove and heating it at medium-low heat, stirring until it is melted again. 
If you are making it ahead of time, you can leave it at room temperature until ready to use (I would leave it out for several days, but I’m not a food saftey specialist). Then, warm on medium-low heat in a saucepan, stirring until smooth before using.
This recipe produces enough caramel to frost 24 cupcakes or a two layer 8″ round cake.

    I first learned how to make caramel icing almost exactly like this right by my great-grandma’s side as a child. She did not have a thermometer so she taught me to know it’s ready by look & feel in the pan. Thank you so much for giving me back a recipe that also brings back memories of our times in the kitchen.

    I am a Southerner. Icing is the Southern word for frosting. The terms are used interchangeably by every cook I know, and that number is legion.

    This recipe is awesome! It definitely takes patience to stir, but the icing turns out beautiful. Anyone who has a problem, simply cannot follow rules. Just stir stir stir, and it will be perfect. Thanks, I really enjoy this recipe. I’ve made four caramel cakes with this recipe, and everyone loved it.

    My mammal taught me this very technique only she used 1 cup heavy whipping cream instead of evaporated milk and it is delicious! I just take my time and make for special occasions!

    Just tried this icing and it is yummy! I struggled with making a caramel icing that is NOT runny. This was definitely the answer to my problem and taste excellent Thanks so much for sharing.

    This is one of the best carmel icings I’ve made in a long time. Yes… there’s a lot of stirring but so worth it. Give it a try you won’t be disappointed I promise. :)

  13. Barbara Williamssays:

    Sounds good will be making Sunday

  14. Lesliesays:

    My grandmother made her caramel icing very much like this. The problem I have every time I make it and frost the cake the icing falls off the cake when I cut it! So you end up with cake on a plate with the icing on the side! Any suggestions how to keep this from happening?

  15. Annsays:

    This is a great recipe. Instead of 2 1/2 cups of granulated white sugar I use 1 1/2 sugar and 1 cup of light brown sugar. I did not melt the 1/2 cup sugar in the iron skipper. The brown sugar took Carr of that process. A wonderful recipe.

    • Ladylovesays:

      I normally make 3 layered 8 inch cakes. How can I make enough caramel icing to frost three layers without having too much left over?

  16. Lizsays:

    Awesome flavor!! Tastes like Werthers caramels!! 2 things, the 1st time I attempted to put the browned sugar in the butter mixture, it turned solid as a rock but luckily it started in one huge chunk so I was able to get it out and try again. The 2nd time worked pretty good. But then I waited too long to pour it on the cake so it was a little difficult to spread. So good though, I just hope the caramel isn’t solid as a rock tomorrow! Thanks for the awesome recipe!!

  17. Lirasays:

    Thanks for the recipe.

  18. Danasays:

    I don’t have enough granulated sugar, could I substitute the white for brown sugar?

  19. Laurasays:

    Thank you for this recipe! I’m going to try it to prove to my mother that I can do a real caramel icing and the tradition won’t die! Is this enough frosting for a 2 layer cake?

  20. Daylisays:

    hello! I did this recipe and I think that is similar to buttercream, my question is: what is the difference between buttercream and this recipe that you show here?

      Buttercream is frosting made from butter, Crisco & powdered sugar. It isn’t cooked either. Completely different from this recipe.

  21. Betsysays:

    This recipe makes a delicious icing that tastes a lot like pralines. It hardened nicely on my cupcakes. I did have to add a few drops of whipping cream as the icing cooled to make it spreadable again, but I might be a slow froster. Thanks for the great recipe!

  22. Ms. Marcisays:

    Tried this for the first time. So far it’s too thin for icing. My great-aunt gave me this recipe over 10 years ago, and I have misplaced it. This sounds similar to hers. I under stand why at 80+ “Aunt Geneva’s Caramel Cake” is only made on very special occasions. Thanks for the recipe.

  23. Anonymoussays:

    this recipe is soooo good..made a caramel cake last night and it is gone this morning! My husband asked if I could make another one..I found that the caramel taste even better after it sits..I didnt have a candy thermomètre I just use the water ball method..a keeper, a keeper, a keeper

  24. Anonymoussays:

    This recipe us great! It takes patience but is worth every second. I waited a little too long to frost my caramel cake so part of it looks ok and most of it doesn’t look too pretty….but wow! It is so delicious. It is for my husband’s birthday and he could barely contain himself. This one is going right into my recipe book, I can’t wait to try it again. Thanks so much!

    My Mother taught me how to make Carmel from scratch years ago . I had forgotten some of it but this is almost the same,as my memory is refreshed, making it today for my Grandaughter thank you so much

    Is this the caramel recipe that you used in the pumpkin spice macarons?

      I have been trying to make this icing for over 20 years. I have finally acheived the taste I wanted. I made a carmel cake yesterday, I only have a couple of slices left today. Once you start eating it, you can’t stop. My family and I just want to thank you for putting this recipe online.

  27. Grandmother2ninesays:

    Sounds great

  28. Anonymoussays:

    can this be made ahead, stored in the fridge and then reheated when needed?

  29. Anonymoussays:

    Would it be possible to add this to a buttercream to create a fluffier frosting? Or would that be way too sweet?

    Sounds delicious!!

    This is the way I remember my great Aunt Viola making the icing. I remember seeing her use a skillet to melt her sugar on her wood stove. She is the only family member I remember as a child who made caramel cake…the task was too daunting for everyone else I guess. Thanks for the opportunity to recreate a memory.

    I just made this icing to go on my cake and it’s soooooo gooood. Very happy with the results =)

  32. Stefsays:

    Sara – It gets a crunchy top as it cools, but it’s still creamy on the inside.

  33. Sara Sunshinesays:

    Do this caramelicing dry out and become hard our is it more like frosting, which stayes wet and creamy?

  34. Ferozasays:

    I’ve been dying to make a caramel cake, ever since I read The Help, and your cupcakes and icing were fabulous! Great instructions too, really well laid out for a first time caramel icing maker! Thank YOU!

  35. Anonymoussays:

    5 stars
    This is a great recipe. You have to take your time and not “multitask” but it has perfect flavor and texture. I did add a pinch of salt. To frost a 7 layer I had to make 2 consecutive batches because I take too long to apply frosting but it was amazing!

  36. Anonymoussays:

    I found I need an extra set of hands to pour the carmael into the milk mixture. It hardened in the mixture before I could incorporate it. However, it still turned out great!!! The caramel melted as the temp rose the the softball stage

  37. Anonymoussays:

    My grandmother’s cousin gave her almost the identical recipe, the only difference being that it calls for heavy cream, rather than evaporated milk and butter. A bit less fuss and works perfectly. Otherwise, it’s exactly the same. I use a small pyrex skillet to caramelize the sugar

  38. Karensays:

    I loved loved loved The Help! Thanks for making the book come alive with these cupcakes. I can’t wait to try them.

  39. Stefsays:

    Holly – I think you could you another kind of skillet, but since I haven’t tried it, I can’t promise that you will have the same results.

  40. shannon abdollmohammadisays:

    Dang…this is awesome!! Thanks for sharing…love the step-by-step pics.

  41. CupCake Kicksays:

    I must try this TODAY!

  42. Tarasays:

    I am not opposed to eating this straight out of the pot. YUM!!!

  43. Virginiasays:

    The first time I made caramel it came out GREAT, probably because I took my time and read the recipe very carefully. The next time I definitely tried to rush it — NOT a good idea. I had not heard about the two separate mixtures, looking forward to trying that. Thanks.

  44. Joannesays:

    why didn’t i check this last night?! i attempted caramel icing for the first time last night and made such a mess :(
