Confetti Cupcakes with Pink Strawberry Buttercream Frosting

This recipe is so simple to make and people will have no idea that it comes from a cake mix! It really is one of the softest and most delicious cupcakes I have ever eaten. You can add any color of sprinkles to the cake batter to match the occasion.
The best part about this cupcake is the frosting . . . I have been looking for a fresh strawberry frosting recipe and after lots of trial and error, I came up with this one after combining lots of ideas from other recipes. It ends up being fluffy and light . . . I could seriously eat it by itself with a spoon! The strawberry flavor is delicious!

Confetti Cupcakes
1 box white cake mix (I used a 16.25 oz Duncan Hines cake mix)
4 egg whites
1/4 cup oil
3/4 cup milk (I used 1%)
3/4 cup sour cream (I used light)
2 teaspoons vanilla extract
1/2 cup jimmies or sprinkles (whatever color you want)

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 3/4 full with cupcake batter and bake at 350 degrees for 15-20 minutes (or until a toothpick stuck in the middle of a cupcake comes out clean).
Adapted from Your Cup of Cake

Pink Strawberry Buttercream Frosting
1 cup (2 sticks) of butter at room temperature
1 teaspoon of vanilla extract
1/3 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

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).

    How long do you think it would take to bake if I made it as 2 eight or nine inch rounds? My daughter’s sweet sixteen is coming up & she absolutely loves these two flavor combinations. Looking to give this recipe a try.

      We’ve only made them as cupcakes. So after about 20 minutes, just keep checking on them til a toothpick inserted in middle comes out clean. Just need to be sure it is cooked through, but not too done. Hope it all works out well and your daughter has a great 16th birthday! -The Six Sisters

    I bake ALL the time…bread,cakes of all kinds,cookies etc etc. I made 117+ of them for a grad party.My oldest son(29) announced that these were the best thing I have EVER made! Note..he does not like chocolate(aliens must have dropped him here) I added strawberry ext to the frosting to give it a bit more strawberry flavor. ..other than that, by the recipe.
    Thanks so much! Sue
