Banana Cupcakes With (The Best) Chocolate Meringue Frosting

Banana Cupcakes
makes 12-18 standard size cupcakes or 24-36 mini cupcakes, depending how tall you like them
3/4 cup whole wheat pastry flour
3/4 cup, plus 2 tablespoons cake flour
2/3 cup natural cane sugar
1 teaspoon baking powder
1/2 teaspoon baking soda
1/4 teaspoon salt
1/2 cup (one stick) unsalted butter, melted
1 1/2 cups mashed bananas (about 4 ripe bananas
2 large eggs
1/2 teaspoon pure vanilla extract
Preheat oven to 350 degrees. Grease a standard or mini muffin pan or line with paper liners. In a medium bowl, whisk together flours, sugar, baking powder, baking soda, and salt. Make a well in the center of the flour mixture. In well, mix together butter, mashed bananas, eggs, and vanilla. Stir until just combined. Distribute batter evenly among the muffin cups.

(slightly adapted from Chocolate Buttercream in the Well-Decorated Cake)
This recipe takes some time, but it makes enough for at least two layer cakes or six dozen cupcakes. I always make the full recipe and freeze half to two thirds. Just defrost, re-whip, and it's as good as new. It's perfect for making impromptu cakes, which, as everyone knows, are the very best kind.
2 1/2 cups unsalted butter, at room temperature
3 lbs confectioners' sugar
1 cup high quality Dutch processed cocoa powder
3 tablespoons meringue powder
1/3 cup kahlua or chocolate liqueur
2 tablespoons milk
1 tablespoon pure vanilla extract
2 cups ganache (I consider this optional. It certainly makes the chocolate flavor more intense, but the frosting is still delicious without it if you're short on time)
Prepare the ganache, if using. Cream the butter for two minutes. Scrape the bowl and cream for an additional minute. Sieve cocoa powder and confectioners' sugar together (note: this will take much longer than you think). Add the sugar mixture one cup at a time to the creamed butter. Mix until well blended. Add meringue powder and beat for one minute. Mixture will appear dry.
makes 3 1/2 cups
1 1/2 cups heavy cream
1 lb high quality semisweet or bittersweet chocolate, chopped roughly into pieces
In a heavy saucepan, boil heavy cream. Remove from heat. Add chocolate pieces and use a rubber spatula to stir until the chocolate is melted. Pour into a room-temperature bowl and cover with plastic wrap. Refrigerate until firm.
