Equipment

  • Mixing Bowls
  • Whisk or Mixer
  • Cake Pans
  • Spatula

Ingredients
  

Chocolate Cake Base

  • 1 3/4 cups all-purpose flour sifted
  • 3/4 cup unsweetened cocoa powder use best quality available
  • 2 cups sugar
  • 2 tsp baking powder
  • 1 1/2 tsp baking soda
  • 1 tsp salt
  • 2 eggs room temperature
  • 1 cup buttermilk or milk + 1 tsp vinegar
  • 1/2 cup vegetable oil or melted butter
  • 2 tsp vanilla extract double for richer flavor
  • 1 cup hot coffee deepens chocolate flavor

Frosting Ideas

  • 1 batch chocolate buttercream or ganache for classic design
  • 1 batch raspberry preserves or caramel for filling between layers

Instructions
 

  • Preheat oven to 350°F (175°C). Grease and line 2 round cake pans.
  • In a large bowl, sift flour, cocoa, sugar, baking powder, baking soda, and salt.
  • In another bowl, whisk eggs, buttermilk, oil, and vanilla until smooth. Gradually add wet ingredients to dry and mix until just combined.
  • Stir in hot coffee carefully—the batter will be thin, but that’s what makes the cake moist.
  • Divide batter into pans and bake 30–35 minutes, or until a toothpick comes out clean. Cool completely before frosting.
  • Frost with buttercream, ganache, or filling of choice. Decorate simply with powdered sugar, drip glaze, berries, or edible flowers depending on occasion.

Notes

For men: try coffee ganache, stout cake, or bold toppings like pretzels and popcorn. For women: add raspberry layers, flowers, or gold dust for elegance. For easy designs: dust with cocoa, drizzle with ganache, or top with chocolate bars. Alternatives: brownies, trifles, flourless cakes, or chocolate ice cream cakes.
