Ingredients

For the Cupcakes:

  • 185 g all-purpose flour
  • 60 g dutch process cocoa powder
  • 185 g granulated sugar
  • 1 ½ teaspoon espresso powder
  • ½ teaspoon salt
  • 1 ½ teaspoon baking powder
  • ¼ teaspoon baking soda
  • 90 g neutral oil
  • 80 g whole milk
  • 85 g plain whole milk yogurt
  • 2 eggs, room temp
  • 1 teaspoon vanilla extract
  • 150 g boiling water

For the Burnt Sugar:

  • 100 g granulated sugar
  • 28 g water
  • ¼ teaspoon baking soda

For the German Buttercream:

  • 4 egg yolks
  • 100 g granulated sugar
  • 14 g cornstarch
  • 2 teaspoon vanilla extract
  • 227 g whole milk
  • 227 g unsalted butter, 2 sticks, room temp
  • 75 g burnt sugar, blended into a powder

Instructions

For the Cupcakes:

  • Preheat the oven to 350 degrees F and line a cupcake pan with parchment cupcake liners. 
  • In a large bowl, whisk together the flour, cocoa powder, sugar, espresso powder, salt, baking powder, and baking soda. 
  • To the dry ingredients, add the oil, milk, yogurt, eggs, and vanilla, and mix until fully combined. 
  • Mix in the freshly boiled water. 
  • Transfer the batter to the cupcake pan, filling each about ⅔ full. 
  • Bake the cupcakes for about 16 minutes or until a toothpick inserted comes out clean. 
  • Allow to cool completely before decorating.

For the Burnt Sugar:

  • Line a baking sheet with aluminum foil and grease with butter. 
  • Heat granulated sugar and water in a saucepan over medium heat, stirring occasionally until the sugar dissolves.
  • Once it begins to bubble, increase the heat to medium-high and swirl the sugar (do not stir) to encourage even cooking.
  • After about 10 minutes, it will turn amber in color. Remove from heat and quickly whisk in the baking soda. It will bubble up a lot. 
  • Pour into the prepared pan, careful not to deflate the bubbles. 
  • Allow to cool completely before breaking into pieces and blending into a powder.

For the German Buttercream:

  • Start with the pastry cream - heat the milk and vanilla extract in a saucepan, and bring to a simmer or about 200 degrees F.
  • Whisk the egg yolks, sugar, and cornstarch together for 2-3 minutes until light in color.
  • Once the milk is simmering, slowly pour half into the egg-sugar mixture, whisking at the same time to temper the eggs. 
  • Pour everything back into the saucepan and heat over medium heat, whisking constantly. After a couple minutes, a layer of bubbles will form over the top and it will begin to thicken.
  • Once the bubbles disappear, continue whisking for one more minute, then remove from heat.
  • Transfer to a bowl and cover with plastic wrap, pressing it directly up against the pastry cream to prevent a skin from forming. Chill overnight. 
  • Make the buttercream by beating the pastry cream for about 10 minutes on low speed until it warms up to about 70 degrees. 
  • Add the butter, a few cubes at a time, and beat on medium speed. If it looks curdled at all, continue beating on low speed until smooth.
  • Blend the burnt sugar into a powder and add to the buttercream, mixing until fully combined. 

For Assembly:

  • Transfer the buttercream to a piping bag with a medium star tip (I used Wilton 1M).
  • Once the cupcakes are completely cool, pipe rosettes onto each cupcake.
