Crumb Cake

This crumb cake is made with sour cream for tang and topped with big fat crumbs! People can’t get enough of it!

Sour Cream Coffee Cake

Sometimes, crumb cakes lean towards dry (you really need that cup of coffee to help it go down).  Not so with this one!

This crumb cake is super moist and tastes of brown sugar, cinnamon, and giant bear hugs.

The Difference Between Crumb Cake and Coffee Cake

The term crumb cake and coffee cake can be used interchangeably. They are both unfrosted cakes with a crumb topping.

New York crumb cake (which this cake is not) is a special kind of crumb cake with a nearly equal amount of crumbs and cake.

If you want more crumbs on this cake, go for it! Just double the crumb part of this recipe. The more crumbs, the merrier!

How to Make Crumb Cake Topping

Crumb Topping Ingredients

Oats are the secret ingredient in the perfect crumb topping! It gives the topping a great texture.

I also always use brown sugar rather than white sugar in crumb topping as I love the flavor!

Crumb Cookies

I love my crumb topping so much that sometimes I bake just the topping into crumb cookies!

Crumb Topping Variation

Apple Pie Crumb Topping

If you want to switch it up, you can use granola or nuts in the topping.

I like using this technique when I make my crumb topping for apple pie.

Crumbs in the Cake

Sour Cream Coffee Cake

My crumb cake is a bit unconventional in that it uses crumbs both in the batter and on top of the cake.

As you can see above, the crumbs in the batter won’t be visible in the end, but they make the cake nice and moist and buttery.

Using Greek Yogurt Instead of Sour Cream

substituting yogurt for sour cream

My crumb cake recipe uses sour cream to give the cake a little bit of a tang.

I’ve done extensive testing and found that you can replace the sour cream with yogurt or Greek yogurt and not notice any difference. So, use whatever you have on hand.

    We had this for afternoon tea at the weekend and it was so moist. I can’t believe what a difference the sour cream makes to a cake.

    My only complaint…it wasn’t enough, everyone wanted the last slice! ;-)
