funfetti cupcakes with strawberry buttercream

in my house, father's day isn't so much about my father or my brother (who also happens to be a father), it somehow ended up being all about my niece. so naturally, funfetti cupcakes with a pinkish frosting and extra sprinkles were on the menu. or rather, they were the menu...

cupcakes (modified from this recipe):

1 1/4 cup unbleached all-purpose flour
1 1/2 tsps baking powder
1/4 tsp salt
1/2 cup sugar
6 tablespoons unsalted butter, at room temp
1 egg + 1 egg white
2 tsps vanilla extract
1/2 cup unsweetened soy milk
2 tablespoons rainbow sprinkles

Preheat oven to 350 F.

In a medium sized bowl combine the flour, baking powder, and salt. in a larger bowl, cream together the butter and sugar until smooth, add the egg, egg white, and vanilla and mix well. add the flour and milk in alternating batches, starting and ending with flour (1/3 of the flour, 1/2 the milk, 1/3 of the flour, 1/2 of the milk, 1/3 of the flour). fold in the sprinkles and avoid over mixing.
line a cupcake pan and fill each liner about 2/3 of the way through. bake for 20-22 minutes or until a toothpick inserted in the middle comes out clean. cool completely before frosting.

frosting:

1/2 cup butter (1 stick), at room temp
2/3 cup confectioner's sugar
1 tsp vanilla extract
1 tsp cocoa powder
3 tablespoons strawberry puree (i blended 3 large strawberries, then ran the mixture through a sieve to remove the seeds)

beat the butter until it is light and fluffy. add the confectioner's sugar in 1/3 batches and mix well. add the cocoa, vanilla, and strawberry puree and mix well again. spread or pipe on cupcakes and decorate with sprinkles.
