Cupcake Ingredients

• 1 box spice cake mix
• 1 cup water
• 1/2 vegetable oil
• 3 eggs
• ½ cup quick oats

Frosting Ingredients

• 2 cups powdered sugar, sifted
• 1/2 cup unsalted butter, softened to room temperature
• 1 tsp. vanilla extract, (my favorite brand)
• About 1 or 2 Tbsp milk
• 2 teaspoons cinnamon
• ½ teaspoon nutmeg
• 6 oatmeal cream pies, crumbled plus 2-4 more, cut into triangles for topping

Directions

Step 1

Preheat the oven to 350°. Place pretty cupcake liners in your cupcake baking pan. Spray each liner lightly with non-stick cooking spray.

Step 2

Follow the directions on the box of spice cake mix except add 1/2 cup of quick oatmeal to the mix. Bake according to package directions for making cupcakes.

Then cool completely on a wire rack before frosting and decorating. While the cupcakes are cooling, make the frosting.

Step 3 Make the frosting

In a large mixing bowl, cream butter until smooth and fluffy using an electric mixer on medium-high speed. A stand mixer with a paddle attachment is a great help for creaming butter.

Once your butter is light and fluffy, Gradually add the confectioners’ sugar a little at a time to avoid blowback, with the mixer on medium speed, until fully incorporated. Add the vanilla and continue to mix.

Now add the crumbled oatmeal creme pies, cinnamon, and nutmeg, and continue to mix. Add about 1 tbsp of milk and continue to beat until the desired consistency is reached.

If the frosting is too thin, add more powdered sugar about a Tablespoon at a time, if the frosting is too thick add a tad more milk.

Step 4 Frost and decorate the cupcakes

Cut about 2 to 4 oatmeal cream pies into triangles and set aside for decoration. You will add those later.

Place your frosting into a piping bag with a star tip or use a Ziploc bag with the corner snipped off and a star tip.

Pipe a nice swirl of frosting on top of each cooled cupcake. Then top the frosting with a triangle-cut piece of oatmeal creme pie for decoration. Serve and enjoy!
