Confetti Cupcakes with Homemade Strawberry Buttercream Frosting
These moist, fluffy, delicious, and FUN Confetti Cupcakes with homemade Strawberry Buttercream Frosting are made using a cake mix!
Serving24 Cupcakes
Ingredients
- 1 box white cake mix, (I used a 16.25 oz Duncan Hines cake mix)
- 4 egg white
- ¼ cup oil
- ¾ cup milk, (I used 1%)
- ¾ cup sour cream, (I used light)
- 2 teaspoon vanilla extract
- ½ cup sprinkles, (whatever color you want)
Frosting:
- 1 cup butter, (2 sticks - at room temperature)
- 1 teaspoon vanilla extract
- ⅓ cup strawberry jam, or preserves (I used our Homemade Freezer Jam)
- 4-5 cups powdered sugar, (just keep adding it until it's the consistency you want)
- 2 Tablespoons milk
Instructions
- In a mixing bowl combine the egg whites, oil, milk, sour cream, and vanilla gently with a whisk. Then sift in your cake mix and sprinkles and gently stir.
- Fill 24 cupcake liners ¾ full with cupcake batter and bake at 350℉ for 15-20 minutes (or until a toothpick stuck in the middle of a cupcake comes out clean).
Frosting:
- Beat butter and vanilla together until fluffy. Add strawberry jam and beat until incorporated.
- Add powdered sugar, 1 cup at a time. Mix until frosting is fluffy. It will seem kind of dry, so add 1-2 Tablespoons of milk until it's the consistency you like.
- Pipe onto cooled cupcakes and top with sprinkles (if you want).
