Some molten-cake recipes call for simply underbaking the batter so the middles stay lava-like, but mini cakes get done so quickly it's best to give them a filling that won't set up. These rich, mocha-flavored morsels are guaranteed to stay moist and gooey, owing to a simple mocha ganache in the middle. Serve the cakes with a scoop of low-fat coffee ice cream and garnish with a chocolate-covered espresso bean, if desired.
Make Ahead Tip: Prepare through Step 5, cover and refrigerate for up to 2 days. After baking (Step 6), the cakes will keep in the pan, tightly covered with foil, for up to 1 day. The sauce (Step 7) will keep, covered, in the refrigerator for up to 5 days. To serve, reheat the cakes in the covered pan at 350 degrees F for 10-12 minutes. Reheat the sauce in a microwave on medium for about 20 seconds. | Equipment: 12-cup mini muffin pan
- 4 ounces dark or bittersweet chocolate (60-75% cacao), coarsely chopped
- 2 tablespoons unsalted butter cut into chunks
- 1 tablespoon granulated sugar
- 1 1/2 tablespoons light cream
- 2 teaspoons instant espresso powder or granules dissolved in 1 tablespoon hot water, divided
- 1 tablespoon light corn syrup
- 1 large egg
- 2 tablespoons canola oil
- 1 teaspoon vanilla extract
- 1/8 teaspoon salt
- 5 tablespoons confectioners' sugar
- 3 tablespoons all-purpose flour
- 1 tablespoon unsweetened Dutch-process cocoa powder
- 1-3 teaspoons very hot water
- Tip: No Microwave? Melt chocolate in a double boiler instead: Place chopped chocolate in the top of a double boiler over hot, but not boiling water. Gently stir until the chocolate is almost melted. Remove from the heat and stir until it melts completely.
Position a rack in the center of the oven; preheat to 350 degrees F. Generously coat the mini muffin pan with cooking spray.
Place the chocolate and butter in a medium microwave-safe bowl. (alternatively, see tip). Microwave on high for 1 minute. Stir well, then continue microwaving on medium, stirring every 20 seconds, until the remaining chocolate melts completely.
TO PREPARE THE FILLING:
Stir together the granulated sugar, cream and half the espresso mixture in a small microwave-safe bowl. Microwave on high just to steaming, 20-40 seconds. (Alternatively, combine in a small saucepan and heat over medium-low heat until just steaming). Stir until the sugar dissolves. Add the corn syrup and half the melted chocolate (reserve the other half for the batter); stir until completely smooth. Cover and transfer to the freezer until cold and firm, about 30 minutes.
TO PREPARE THE BATTER:
When the filling has been chilling for 20 minutes, whisk the egg, oil, vanilla, salt and the remaining espresso mixture in a medium bowl until very smooth. Return the remaining chocolate mixture to the microwave. Microwave on medium, stirring every 20 seconds, until just warm again (do not overheat). In two batches, whisk the egg mixture into the warm chocolate until well blended. Sift the confectioners' sugar, flour and cocoa over the batter and whisk in just until smoothly incorporated.
TO ASSEMBLE THE CAKES:
Remove the filling from the freezer. Spoon half the batter into the mini muffin cups, about 1 rounded teaspoon per cup. Spoon 1/2 teaspoon filling onto the center of each (reserve the rest for the sauce). Divide the remaining batter evenly among the muffin cups, about 1 rounded teaspoon per cake. Smooth out the batter to cover the filling.
Bake the cakes on the middle rack until the edges look dry and puffed but the centers still look very underdone and puddinglike, 6-9 minutes. Let cool on a wire rack until firm, about 2 minutes. Place a cutting board on top of the pan and invert the mini cakes out onto it. If the cakes are stuck to the pan, run a knife around and under them to loosen.
TO PREPARE SAUCE & SERVE:
Thoroughly stir very hot water into the reserved filling, 1 teaspoon at a time, until very smooth and slightly fluid. Serve the warm cakes drizzled with the sauce.
