1/2 c. cake flour
1 Tbsp. baking powder
1 tsp. salt
2 sticks butter, softened
2 1/4 c. sugar
3 large eggs
1 egg white
1 c. buttermilk
1 1/2 tsp. vanilla extract
1 lb. strawberries, pureed
A few drops of red food coloring
Reduce speed to low. Combine buttermilk and vanilla together and set aside. Add dry ingredients to creamed mixture in 3 additions, alternating with the milk mixture; end with the dry ingredients. Fold in strawberries. If desired, add a few drops of red food coloring until a pretty pink color is reached. Scrape the sides of the bowl to ensure everything has been mixed in. Divide batter among muffin cups (about 30), filling them almost all the way to the top.
Bake cupcakes until a knife inserted into the centers comes out clean, about 22-25 minutes. Allow to cool in muffin tins.
For the frosting, cream shortening until fluffy. Add sugar, and continue creaming until well blended. Add salt, vanilla, and 6 ounces whipping cream. Blend on low speed until moistened. Add additional 2 ounces whipping cream if necessary. Beat at high speed until frosting is fluffy.
I piped the frosting out with a pastry bag and then sprinkled with pink sprinkles!
