~about regular 16 cupcakes
- 2 1/2 cups all-purpose flour
- 2 teaspoons baking powder
- 1/2 teaspoon salt
- 3/4 cup strongly brewed coffee, cooled to warm
- 1/4 cup milk
- 1 tablespoon Kahlua
- 12 tablespoons unsalted butter, softened
- 1 1/3 cups sugar
- 6 large egg yolks
- 1 rounded teaspoon instant espresso
- 2 large egg white
- 2/3 cup sugar
- 3 tablespoons light corn syrup
- pinch of salt
- 1/4 cup sugar
- 1 1/2 tablespoon unsalted butter, cut into pieces
- 2 tablespoons heavy cream
1. Place rack in the middle of the oven and preheat to 350 degrees F.Place paper liners in muffin tin.
2. Stir together flour, baking powder, and salt in a small bowl and set aside. Combine coffee, milk, and Kahlua in a cup and set aside.
3. Cream butter and sugar together in the stand mixer (with the paddle attachment) on medium speed, until light and fluffy, about 5 minutes. Beat yolks in one at a time.
4. Reduce speed to low and beat in one-third of the flour mixture, then half of the liquid mixture. Scrape down sides, then beat in another third of flour mixture, then the rest of the liquid, then the remaining flour mixture. Scrape down the bowl and divide batter in half.
5. Leave half of batter as is. Stir instant espresso into the other half.
*Don’t make meringue until cupcakes have cooled.
Set up a double boiler. Whisk together meringue icing ingredients in the bowl of the stand mixer by hand. Put over double boiler and whisk as it warms to about 130 degrees F (sugar dissolved). Attach to mixer and use the whisk attachment on medium speed to whip until cooled, about 5 minutes. Drop onto cupcakes immediately. (Tip: Put something under the wire rack to catch drippings.)
*Making a small amount of caramel is a little more challenging because you have a smaller window of caramelized sugar to burnt. Make sure everything is ready by the stove before starting.
Spread sugar evenly across the bottom of a heavy bottomed saucepot and put over medium-high flame. Try not to touch the sugar but watch carefully as it melts. As soon as it is browning, you can start to stir. When it looks like all of it has browned lightly, remove the pot from heat and stir in butter. Be careful because it will bubble violently. Bring it back to the flame and stir for a few seconds until smooth. Remove from the heat again and add heavy cream, again careful of violent bubbling. Stir rapidly until smooth. Set aside and allow to cool to luke warm.
Drizzle over the cupcakes.
You can make the cake part a day before and store in airtight containers after they have cooled. Once you make the icing you have to plop it on the cupcakes immediately, but once cupcakes have been completely assembled, they can be held in room temperature for several hours before service.
