If you’ve ever had an oatmeal cream pie, it’s likely that it came out of a plastic bag from the grocery store or a gas station market. The Little Debbie’s oatmeal cream pie is a childhood classic.
Oatmeal cream pies are soft and chewy oatmeal cookies stuffed with a thick layer of vanilla frosting. They are some of the best sandwich cookies around, ranking right up there with Oreos!
In my homemade version, I preserve the spirit of the plastic-wrapped oatmeal cream pie but upgrade it with better ingredients.
How to Make Homemade Oatmeal Cream Pies
The Oatmeal Cookies
Oatmeal cream pies start with oatmeal cookies. My favorite oatmeal cookie recipe is below; it’s great with or without the filling!
I always add chocolate chips to my oatmeal cookies because everything is better with chocolate, but you can substitute raisins or simply leave them off for a more traditional oatmeal cream pie.
This recipe will work with any rolled oats (regular or quick cook). The kind you pick is just a personal preference. The quick cut oats are cut finer and the cookies will have less texture than the regular. Do not use steel cut oats as they will end up making the cookies gritty.
The Sandwich Cookie Filling
I fill the cream pies with my favorite vanilla buttercream frosting. (I often make the frosting with vanilla bean paste to give it an even stronger vanilla flavor with the addition of vanilla bean seeds.)
For a fluffier option, you could use marshmallow frosting. Or, if you don’t have time to make filling, you can just shove some marshmallow fluff between two of my oatmeal cookies and call it a day.
Don’t be shy with the frosting. Oatmeal cream pies have a high filling to cookie ratio. Pile it on!
Oatmeal Cream Pie Variations
For a twist, try making chocolate oatmeal cream pie using chocolate oatmeal cookies.
If you love oatmeal cream pies, try making my frozen oatmeal cream pie cheesecake popsicles. They are so totally decadent and perfect for summer.
