These cupcakes came out beautifully. The original recipe (from Sprinkles) was a little too "pound cake" texture for me. So I will add some baking soda the next go round. But the fresh strawberry taste was incredible. I could eat the light fluffy frosting all day.
2/3 cup whole fresh or frozen strawberries, thawed
1 1/2 cups all-purpose flour, sifted
1 teaspoon baking powder
1/4 teaspoon coarse salt
1/4 cup whole milk, room temperature
1 teaspoon pure vanilla extract
1/2 cup (1 stick) unsalted butter, room temperature
1 cup sugar
1 large egg, room temperature
2 large egg whites, room temperature
Preheat oven to 350 degrees. Line a 12-cup muffin tin with cupcake liners; set aside.
Place strawberries in a small food processor; process until pureed. You should have about 1/3 cup of puree, add a few more strawberries if necessary or save any extra puree for frosting; set aside.
In a medium bowl, whisk together flour, baking powder, and salt; set aside. In a small bowl, mix together milk, vanilla, and strawberry puree; set aside.
In the bowl of an electric mixer fitted with the paddle attachment, cream butter on medium-high speed, until light and fluffy. Gradually add sugar and continue to beat until well combined and fluffy. Reduce the mixer speed to medium and slowly add egg and egg whites until just blended.
With the mixer on low, slowly add half the flour mixture; mix until just blended. Add the milk mixture; mix until just blended. Slowly add remaining flour mixture, scraping down sides of the bowl with a spatula, as necessary, until just blended.
Divide batter evenly among prepared muffin cups. Transfer muffin tin to oven and bake until tops are just dry to the touch, 22 to 25 minutes. Transfer muffin tin to a wire rack and let cupcakes cool completely in tin before icing.
Cream Cheese Filling
1 pkg (8 ounces) cream cheese softened
1/2 cup confectioners' sugar
1/4 cup milk
About 1 1/2 cups.
In large bowl, combine cream cheese, sugar, and milk. Beat with mixer until well blended. Refrigerate until ready to use.
I put the filling in a piping bag with a large round tip and just stabbed the end into each cupcake, squeeze a little, then release.
Fresh Strawberry Frosting
1/2 cup whole strawberries
1 cup (2 sticks) unsalted butter, firm and slightly cold
Pinch of coarse salt
3 1/2 cups confectioners' sugar, sifted
1/2 teaspoon pure vanilla extract
Place strawberries in the bowl of a small food processor; process until pureed. In the bowl of an electric mixer fitted with the paddle attachment, beat together butter and salt on medium speed until light and fluffy. Reduce mixer speed and slowly add confectioners' sugar; beat until well combined. Add vanilla and 3 tablespoons strawberry puree (save any remaining strawberry puree for another use); mix until just blended. Do not overmix or frosting will incorporate too much air. Frosting consistency should be dense and creamy, like ice cream.
