Ingredients:

  • 1.5 cups (190g) all-purpose flour
  • 1 cup (200g) granulated sugar
  • 0.5 cup (45g) dark cocoa powder
  • 1 tsp (5g) baking soda
  • 0.5 tsp (3g) salt
  • 1 cup (240ml) buttermilk
  • 0.5 cup (115g) vegetable oil
  • 1 large egg (50g)
  • 1 tsp (5ml) vanilla extract
  • 0.5 cup (120ml) boiling water
  • 0.5 cup (115g) unsalted butter, softened
  • 2 cups (240g) powdered sugar
  • 2 tbsp (30ml) heavy cream
  • 1 tsp (5ml) vanilla extract
  • 1 pinch (1g) salt
  • 0.25 cup (40g) multi-colored nonpareils

Instructions:

  1. Preheat your oven to 350°F (175°C).
  2. Thoroughly grease the inside of 10 individual 4 oz ramekins with butter or non-stick spray.
  3. Sift the flour, sugar, cocoa powder, baking soda, and salt into a large bowl to remove any lumps.
  4. Add the buttermilk, oil, egg, and vanilla to the dry ingredients. Whisk until just combined, avoiding overmixing.
  5. Carefully stir in the boiling water until the batter is thin and smooth.
  6. Divide the batter evenly among the 10 ramekins, filling them about 3/4 full.
  7. Bake for 22–25 minutes until the edges are set and a toothpick inserted into the center comes out with a few moist crumbs.
  8. Allow cakes to cool in the ramekins for 10 minutes, then transfer to a wire rack to cool completely.
  9. Prepare frosting by beating softened butter, powdered sugar, heavy cream, vanilla extract, and salt until velvety.
  10. Frost the cooled cakes and finish by applying the multi-colored nonpareils.
