  • 1 cup brewed black coffee cooled
  • 1/2 cup vegetable oil
  • 1 tsp vanilla extract

For the chocolate glaze

  • 1 ½ cups icing sugar
  • 4 tbsp cocoa
  • a few tablespoons of hot water

For the filling

  • 2/3 cup sugar

  • ¼ cup cocoa


For the cupcake batter

  1. Combine all ingredients in a mixing bowl and beat with electric mixer for 2 minutes.
  2. Pour into cupcake tins lined with paper liners.
  3. Bake at 350 degrees F for 15-20 minutes or until toothpick inserted in center comes out clean. Cool completely.

For the filling

  1. Combine sugar, corn syrup, and water in a small saucepan. Heat to a rolling boil over medium heat until the temperature reaches 242 degrees F on a candy thermometer (soft ball stage).
  2. As mixture boils beat egg whites until stiff peaks form.
  3. Pour hot syrup very slowly in a thin stream beating constantly at medium speed until all the syrup is incorporated. Beat on high speed until stiff peaks form adding the vanilla in the last minute. Sift the cocoa through a sieve over the frosting and very gently fold in. Do NOT over mix. Using a piping bag with a star tip, fill the center of the cupcakes from the top pushing the tip to the middle of the cupcake and squeezing as you retract the tip. Do not overfill.

For the Glaze

  1. Whisk together 1 ½ cups icing sugar, 4 tbsp cocoa and a few tablespoons of hot water to get a glaze of spreading consistency. You can add a little more icing sugar if the mixture gets too thin. Spread over filled cupcakes. Enjoy!
