I tried to make a meringue frosting for these cupcakes, but it came out way too drippy, so I ended up just whipping up some cream with a bit of sugar. I used superfine sugar, but if you don't have that you can easily substitute confectioner's sugar or regular sugar. Just taste along the way to get it to the proper sweetness. Although the whipped cream frosting was tasty and super easy, I think these cupcakes might be better with a heftier frosting like an American buttercream.
4 1/2 cups cake flour
3 cups sugar
5 1/4 teaspoons baking powder
3/4 teaspoon salt
3 sticks unsalted butter, at room temperature
1 1/2 cups pureed frozen strawberries
8 egg whites
2/3 cup milk
1 to 2 drops red food dye, optional
1 to 1 1/2 cups heavy cream
1 1/2 tsp superfine sugar, more to taste
Sprinkles, to decorate (optional
1. Preheat the oven to 350 degrees. Line three cupcake pans with paper wrappers.
2. Put the flour, sugar, baking powder, and salt in a large mixer bowl. With the electric mixer on low speed, blend for 30 seconds. Add the butter and strawberry puree and mix to blend the ingredients (be sure to cover your mixer bowl with a towel during this step). Raise the speed to medium and beat until light and fluffy, 2 to 3 minutes; the batter will resemble strawberry ice cream at this point.
3. In another large bowl, whisk together the egg whites, milk and red food coloring. Add the whites to the batter in two or three additions, scraping down the sides of the bowl well and mixing only to incorporate after each addition. Divide the batter among the cupcake pans.
4. Bake until a cake tester or wooden toothpick inserted into the center comes out clean (about 20 minutes?).
5. Allow the cupcakes to cool completely. Then whip the heavy cream along with the sugar until stiff peaks form. Add more sugar to taste. Frost the cupcakes and top with sprinkles, if desired.
