For the Cupcakes

  • yellow cake mix box (15.25 oz.)
  • 3 eggs
  • ½ c oil
  • 1 c milk (I used whole)
  • 1 tsp vanilla extract
  • 1 box vanilla instant pudding (3.4 oz. package)
  • ¾ c sour cream

For Chocolate Buttercream Frosting


  • Preheat oven to 350°F.
  • In a medium bowl, whisk together eggs and milk. Add in vanilla, oil, sour cream and pudding mix and whisk to combine. Slowly add in cake mix and stir to incorportate fully. (Remember you do not want to overstir here.)
  • Scoop batter into cupcake lined cupcake pan and fill each liner about ½ full. Bake for about 15-18 minutes or until a toothpick comes out clean. Allow cupcakes to cool completely.
  • While cupcakes are cooling, using a standing or hand mixer, beat softened butter and vanilla until nice and creamy. Add the cocoa powder along with one cup of the powdered sugar and beat until smooth. Continue to add in the rest of the powdered sugar and beat. Slowly add in milk or cream one tablespoon at a time until frosting is to desired consistency.
  • Ice cupcakes with a knife or use a fun icing tip and icing bag.* Either way is amazing! Store cupcakes for several days in an airtight container at room temperature.


If you like a LOT of frosting, you will probably want to double the frosting recipe! If you are just using a knife to spread the frosting then you will be just fine!
