From the moist cake to the fluffy frosting, these scream HAPPY BIRTHDAY! The perfect birthday cake flavor - without the extra work that goes into a traditional cake!
- 1 box yellow cake mix
- 1/2 cup greek yogurt (or sour cream)
- 1/3 cup oil
- 3/4 cup buttermilk
- 2 teaspoons vanilla
- 3 eggs
- 1/2 cup butter, softened
- 2 teaspoons vanilla
- 2 tablespoons heavy cream
- 3-4 cups powdered sugar
- optional: sprinkles
-
Preheat oven to 325 and fill muffin tins with cupcake liners.
-
Sift cake mix into a medium bowl. In a larger bowl combine, greek yogurt (or sour cream), oil, buttermilk, vanilla, and eggs and whisk until smooth. Add cake mix and mix until smooth.
-
Fill cupcake liners 3/4 full and bake 13-18 minutes until an inserted toothpick comes out clean.

After cupcakes have cooled completely, cream the butter for two minutes in a large bowl. Add vanilla and heavy cream and mix until smooth.
