Instructions

Chocolate Cupcake Recipe:

  • Begin by preheating oven to 350°F / 175°C, and place 12 cupcake liners in cupcake pan.
  • Add 3/4 cup of buttermilk, 1/3 cup melted chocolate chips and 1 tsp instant espresso powder into a heat proof bowl. Heat in the microwave at power level 7 for 1 minute or over a double boiler until the chocolate has melted.
  • Whisk together until the ingredients have combined, making sure all the chocolate is melted. The mixture might look a little separated, but it will come together once you add in your dry ingredients.
  • Sift the dry ingredients into the wet ingredients (3/4 cup all purpose flour, 3/4 cup granulated sugar, 1/3 cup black or dark cocoa powder, 1/2 tsp salt and 1/2 tsp baking soda) into chocolate espresso mixture and stir until combined.
  • Scrape the sides and bottom of the bowl as needed with a spatula.
  • Add 1/3 cup vegetable oil, 2 large eggs, 1 tsp vinegar and 1 tsp vanilla. Mix just until the batter is smooth.
  • Fill cupcake liners 3/4 full and bake for about 18-19 minutes or until a toothpick comes out with a few moist crumbs.
  • Let the cupcakes cool for 5 minutes in the pan before moving them to a cooling rack to finish cooling.

Black Cocoa Buttercream:

  • Beat 1/2 cup of unsalted butter on a medium speed for 30 seconds with a paddle attachment, until smooth. 
  • Mix in 1 tsp vanilla extract and 1/2 tsp salt on a low speed.
  • Slowly mix in 1 cup powdered sugar and 1/3 cup black cocoa.
  • Add 1/4 cup of heavy cream half through adding in the powdered sugar to make it easier to mix.
  • Mix in 1/2 cup of cooled, melted dark chocolate and a couple squirts of black gel food coloring.
  • Beat on low until the frosting is evenly colored and the desired consistency and color are reached.
  • If the frosting is too thick, add an extra Tbsp of heavy cream. If it's too thin, add in another 1/4 cup of powdered sugar.
  • Stir by hand with a rubber spatula to get the frosting SUPER smooth.
  • Place the frosting into a large piping bag fit with a grass frosting tip and set aside.

Decorating These Soot Sprite Cupcakes:

  • To decorate these soot sprite cupcakes, use a grass tip to pipe black frosting on top of the cooled cupcakes.
  • Top with candy eyes and some colorful sprinkle stars and enjoy.
