Amy Sedaris' Vanilla Cupcakes
1 ½ sticks of unsalted butter
1 ¾ cups of sugar
Beat well, then add:
Add 2 large eggs
2 Teaspoons of pure vanilla (I used 1 tsp vanilla and 1 tsp coconut flavoring)
½ teaspoon of salt
2 ½ teaspoons of baking powder
2 ½ cups of flour
1 ¼ cups of milk
I also added in the zest and juice of one lime to the batter, next time I will do two limes for more flavor.
Beat well, fill cups, and bake at 375 degrees for 18-20 minutes. You should get 24. I made 12 regular and 24 mini cupcakes.
For the filling, I mixed one can of sweetened condensed milk with 3/4 cup key lime juice, 2 drops of green and one drop of yellow food coloring. Once the cupcakes were cooled, I used a piping bag to fill each one with the key lime filling.
For the icing, I made coconut swiss meringue buttercream:
4 large egg whites
1 1/4 cups sugar
1 cup (2 sticks) unsalted butter, at room temp
2 teaspoons coconut flavor
Put egg whites and sugar into the top of a double boiler over a pan of simmering water. Whisking constantly, cook until sugar has dissolved and mixture is warm (about 160 degrees). Pour heated egg whites into the bowl of an electric mixer fitted with the whisk attachment. Beat egg white mixture on high speed until it forms stiff (but not dry) peaks. Continue beating until fluffy and cooled, about 7 minutes. Switch to the paddle attachment. With mixer on medium-low, add butter two tablespoons at a time, beating well after each addition. Increase speed to medium-high; continue beating until frosting appears thick, about 3 minutes. Reduce speed to low; add coconut flavor and continue beating 2 minutes to eliminate air bubbles.
After icing, I topped them with more lime zest! Sublime on a hot day!
