Oatmeal Pie Cupcakes made with an oatmeal and flour blend and flavored with cinnamon. Frosting these cupcakes is a homemade buttercream and topped with an oatmeal pie wedge.
Making Oat Flour
This recipe for oatmeal pie cupcakes has a mixture of all-purpose flour and ground old-fashioned oats.
The easiest way to make oat flour is by using a food processor. It blends easily and gets the desired powdered results.
Adding the other dry ingredients to the powdered oats makes for super easy blending of the dry ingredients. Add the other dry ingredients to the processor and use quick pulses to blend the ingredients together.

Making the Cupcakes
To get light and fluffy cupcakes, it's important to blend the ingredients following the directions.
The buttermilk is added alternately with the dry mixture so that it doesn't get overbeaten.
If you do not have buttermilk, this can easily be substituted for regular milk with 1 teaspoon of lemon juice. Allow the milk to sit for 5 minutes before adding it to the other ingredients.

Oatmeal Pie Cupcakes Buttercream Frosting
Buttercream frosting is incredibly easy to make and it makes piping cupcakes easy. For success when making buttercream frosting, it's important to use softened butter, not chilled, and not melted.
After combining the butter, powdered sugar, and vanilla extract, it is then time to add the milk. Add the milk at 1 tablespoon at a time. Once you reach a smooth but still pipable texture it is ready to use on the cupcakes.
To pipe cupcakes, the recommended supplies are:
- Piping Bag (I prefer reusable)
- Hand Mixer
- Piping Tip
To top these oatmeal pie cupcakes, slice each oatmeal creme pies into 4 equal pieces. Gently place the quartered oatmeal creme pie into the center of the frosting.

Not good. These were way too soft. The flavor was good. I didn’t overbake as the other comment stated. They just didn’t have enough body

It would have been nice to know that they would come out very soft and wet looking, even when a knife comes out clean. I way over-baked mine thinking they weren't done because they looked so wet. There are also no instructions on how to make the buttercream. I used about half as much powdered sugar because 4 cups felt like way too much to me.

If the toothpick or knife comes out clean then they are done baking. :) I will update the recipe to share the directions for the buttercream for those that are unsure on how to make it. Four cups of powdered sugar is pretty basic in buttercream recipes when making a buttercream that can be piped onto cupcakes for decoration.
