Cake Ingredients

  • 3/4 cup all-purpose flour
  • 1/4 cup unsweetened cocoa powder
  • 1/2 tsp baking powder
  • 1/4 tsp baking soda
  • pinch salt
  • 1/4 cup unsalted butter, softened
  • 1/3 cup granulated sugar
  • 1 large egg
  • 1/2 cup milk (or plant-based milk)
  • 1/2 tsp vanilla extract
  • 1 tsp instant coffee (optional for deeper flavor)

Vanilla Buttercream Frosting

  • 1/2 cup unsalted butter, softened
  • 1 cup powdered sugar
  • 1/2 tsp vanilla extract
  • 1 tbsp milk or cream

Decorations

  • Red fondant or edible heart cutouts
  • Small gold edible pearls
  • Optional gold cake topper or stick

Instructions
 

Preparation

  • Preheat oven to 350°F (175°C). Grease and line a 4-inch round baking pan with parchment paper.
  • In a bowl, whisk together flour, cocoa powder, baking powder, baking soda, and salt.
  • In another bowl, beat butter and sugar until light and creamy.
  • Mix in the egg and vanilla extract until smooth. Stir in milk and instant coffee if using.
  • Gradually add dry ingredients into the wet mixture, stirring until you have a smooth, thick batter.

Baking

  • Pour batter into the prepared pan and bake for 20 to 25 minutes or until a toothpick inserted in the center comes out clean.
  • Allow the cake to cool completely before frosting.

Prepare the Frosting

  • Beat butter until fluffy, then add powdered sugar, vanilla, and milk. Whip until smooth and creamy.

Assembly

  • Slice the cake into two layers. Spread buttercream between layers, then cover the entire cake with a smooth layer of frosting.
  • Add red fondant hearts around the cake and place small gold pearls in between. Finish with piped buttercream swirls on top and a golden topper for a classy final touch.

Notes

Storage: Keep in an airtight container in the refrigerator for up to 4 days. Make Ahead: Bake the cake a day early and frost when ready to serve. Flavor Twist: Add a teaspoon of hazelnut spread between layers for a chocolate-nut flavor. Serving Idea: Present in a small bento box or on a gold cake board for a romantic touch.
