1 pkg. Brownie Mix
1 pkg. Yellow Cake Mix
Preheat oven to 350. Line muffin tins with cupcake liners. For first step combine one box of brownie mix, 2 eggs, 1/2 cup vegetable oil, 1/4 cup water. Mix all ingredients until completely incorporated, make sure to not over mix. Spoon brownie batter into cupcake liners and fill about 1/3 full.
For next step combine in large bowl- 2 eggs and 2 egg whites, 1/3 cup vegetable oil, 3/4 cup buttermilk, 3/4 cup sour cream, and 1 teaspoon vanilla. Sift in one box of yellow cake mix and combine all together. Spoon yellow cake mixture on to brownie batter filling remainder of muffin tins, about 2/3 way full.
Bake cupcakes for 20-22 minutes and remove. Let cool completely before frosting.
For frosting, beat one cup butter, softened and 8 oz. of cream cheese until mixture becomes light and fluffy.
In a blender add 1/4 cup frozen strawberries, thawed and a tad bit of water, blend until smooth. Add 1/4 cup strawberry puree to frosting and mix well. Gradually add in 4-6 cups of powdered sugar.
After cupcakes have cooled I usually add frosting to a large gallon ziplock bag and cut a small snip out of the corner and pipe frosting onto cucpakes. Enjoy!
