Ingredients

Scale
  • 1 3/4 cups all-purpose flour
  • 3/4 cup unsweetened cocoa powder
  • 2 teaspoons baking soda
  • 1 teaspoon baking powder
  • 1 teaspoon salt
  • 2 cups granulated sugar
  • 1 cup buttermilk
  • 1/2 cup vegetable oil
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1 cup hot brewed espresso coffee
  • 1 cup (2 sticks) unsalted butter, softened
  • 4 cups powdered sugar, sifted
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon salt
  • 1/4 cup heavy cream
  • 1/2 cup salted caramel sauce (plus extra for drizzling)
  • For Decoration: Black, deep red, or gold edible dust, optional dark chocolate shavings

Instructions

  1. Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans. Line the bottoms with parchment paper.
  2. In a large bowl, whisk together the flour, cocoa powder, baking soda, baking powder, and salt. Add the granulated sugar and whisk again to combine.
  3. In a separate bowl, whisk together the buttermilk, vegetable oil, eggs, and vanilla extract. Pour the wet ingredients into the dry ingredients and mix on low speed until just combined.
  4. Carefully pour the hot espresso coffee into the batter and mix until smooth. The batter will be thin.
  5. Divide the batter evenly between the prepared cake pans. Bake for 30 to 35 minutes, or until a wooden pick inserted into the center comes out clean.
  6. Let the cakes cool in the pans for 10 minutes before inverting them onto a wire rack to cool completely.
  7. Prepare the Salted Caramel Buttercream: In a large bowl, beat the softened butter until creamy. Gradually add the sifted powdered sugar, alternating with the heavy cream, beating until smooth.
  8. Beat in the vanilla extract and salt. Mix in the 1/2 cup of salted caramel sauce until fully incorporated and the buttercream is light and fluffy.
  9. Once the cakes are completely cool, place one layer on your serving plate. Spread about one-third of the buttercream evenly over the top.
  10. Place the second cake layer on top. Frost the top and sides of the entire cake with the remaining buttercream.
  11. For a sophisticated look, use a small offset spatula to create clean, structured sides. Drizzle extra salted caramel sauce over the top edge, allowing it to drip down the sides.
  12. Decorate with edible gold dust or dark chocolate shavings to achieve an elegant, earthy, or constellation theme. Chill the cake for 30 minutes before slicing.

Notes

  • For the richest flavor, use high-quality dark cocoa powder and freshly brewed espresso.
  • If you prefer a galaxy look, reserve some buttercream, tint it black or deep blue, and use an offset spatula to create swirls before adding edible stars or dust.
  • This cake pairs well with a strong black coffee or a deep red wine.
