Ingredients

Cupcakes

  • 1 1/2 cup all-purpose flour (197 g)
  • 3/4 cup granulated sugar (135 g)
  • 1/4 teaspoon kosher salt (1g)
  • 1 teaspoon baking powder (4 g)
  • 1/4 teaspoon baking soda (2 g)
  • 3/4 cup buttermilk (170 g, room temperature)
  • 1/3 cup vegetable oil (67 g)
  • 1 large egg (room temperature)
  • 1 large egg yolk (room temperature)
  • 1 tablespoon pure vanilla extract (13 g)

Frosting

  • 4 oz egg white (115 g)
  • 3/4 cup granulated sugar (135 g)
  • 3/4 teaspoon vinegar (4 g)
  • 10 oz unsalted butter (283 g, room temperature, cubed)
  • 1/2 teaspoon vanilla (2 g)
  • 4 oz dark chocolate (115 g)
  • 1 tablespoon dutch-processed cocoa powder (7 g)

Instructions

Make the cupcakes

  • Preheat oven to 350°F and line a muffin pan with cupcake liners and set aside.
  • In a small mixing bowl, add flour, sugar, salt, baking powder and baking soda. Mix with a whisk to distribute evenly. Set aside.
  • Add buttermilk, vegetable oil, egg, and vanilla extract to a medium bowl. Beat together with a whisk until smooth. Add the flour mixture to the wet ingredient mixture and fold until just combined.
  • Use a large ice cream scoop to divide batter into the previously prepared muffin pan. One flat scoop of batter for each cupcake cavity, or about 1/4 cup of batter each.
  • Bake in the middle oven rack for 17 minutes until a toothpick inserted in the middle of a cupcake comes out clean. Remove from the oven and allow to cool to the touch, remove cupcakes from the pan and allow to cool completely on a wire rack.

Make the frosting

  • Melt the chocolate in a heat proof bowl over a pot of simmering water just until most is melted. Continue to stir as you take it off the heat until all the chocolate is completely melted and smooth. Set aside to cool.
  • Add egg white to the stand mixer bowl and beat with a wire whisk attachment on medium low speed until frothy.
  • Increase speed to medium and slowly add sugar, one tablespoon at a time to allow it to incorporate into the egg white. Half way through adding the sugar, stream in the vinegar. Then continue to add the sugar until all gone.
  • Increase speed to medium high speed and beat until stiff peak forms and the meringue is shiny and smooth.
  • Reduce speed to medium low and slowly add the room temperature cubed butter, one cube at a time and allow it to incorporate into the meringue. When all the butter is added it will look chunky, like cottage cheese.
  • Add vanilla and increase mixer to high speed and beat for 4-5 mins until buttercream is formed and smooth. Add the completely cooled melted chocolate and cocoa powder and beat until completely incorporated and fluffy.

Assemble the cupcakes

  • Add a piping tip of your choice to a pastry bag, fill with the frosting and add frosting to the cooled cupcakes.
  • Garnish with sprinkles if desired.
