Ingredients

Scale

Cake:

  • 2 1/2 cups of all-purpose flour (about 325g)
  • 1 1/4 cups of sugar (around 275g)
  • 2 1/4 teaspoons of baking powder
  • 1/4 teaspoon of baking soda
  • 2/3 teaspoon of salt
  • 2 eggs
  • 2/3 cup of vegetable oil (approximately 120g)
  • 3/4 cup of buttermilk (create it by mixing 3/4 cup of milk with 1.5 teaspoons of vinegar – about 180g)
  • 2 teaspoons of instant coffee
  • 1/4 cup of boiling water (roughly 60g)
  • 2 tablespoons of cocoa powder

Dalgona buttercream:

  • 1 to 1.5 tablespoons of instant coffee (start with 1, taste, and adjust)
  • 1 cup of icing sugar (about 125g)
  • 1.5 tablespoons of hot water
  • 1 cup of butter (softened to room temperature, which is around 227g)
  • 1.5 cups of icing sugar (approximately 250g)


Instructions

  1. Preheat your oven to 350°F and get those 2 pans (9″) prepped with parchment and butter.
  2. In a big bowl, mix together flour, sugar, baking powder, baking soda, and salt.
  3. Add eggs, oil, and buttermilk, and whisk until just combined.
  4. Time for the magic touch – mix instant coffee with hot water and pour it into the batter. Give it a good stir.
  5. Pour 1/3 of the batter into another bowl. Sift in the cocoa powder and gently fold it in.
  6. Divide the original batter equally into the two pans. Spoon on the cocoa-flavored batter, then use a toothpick to create a cool marbled effect.
  7. Bake for 25-28 minutes or until a toothpick comes out with moist crumbs. Let those beauties cool.
  8. Time for the buttercream:
  9. Whisk coffee, sugar, and water until they form a light-colored, thick mixture (we call it dalgona).
  10. In another bowl, whisk butter and 1.5 cups of icing sugar until light and airy. Add the dalgona mix and keep whisking until you’ve got a smooth buttercream. Taste and tweak as needed.
  11. Let’s assemble the masterpiece:
  12. Once the cakes are cool, trim off the domes and cut each into two layers.
  13. Layer them up on a cake stand with that delicious buttercream. Coat the top and edges generously.
  14. Pop it in the fridge for an hour, then get ready to indulge! Enjoy!
