Ingredients
  

Chocolate Snack Cake

  • 1 cup all-purpose flour
  • 1 cup granulated sugar
  • 1/3 cup unsweetened cocoa powder
  • 1 tsp baking powder
  • 3/4 tsp baking soda
  • 1/2 tsp fine salt
  • 1/2 cup warm water
  • 1/2 cup full-fat sour cream
  • 1/4 cup vegetable oil
  • 1 large egg
  • 1 tsp vanilla extract
  • 1 tsp instant espresso powder optional, enhances chocolate flavor
  • 1/3 cup chocolate chips, chopped optional, for extra richness

Chocolate Buttercream

  • 1/2 cup unsalted butter, softened
  • 1/4 cup unsweetened cocoa powder
  • 1 tsp vanilla extract
  • 1/4 tsp salt
  • 1 1/2 cups powdered sugar
  • 1/4 cup heavy cream
  • 1/4 cup chocolate chips, melted

Chocolate Ganache

  • 1/4 cup heavy cream
  • 1/3 cup dark or semi-sweet chocolate chips
  • 1 Tbsp unsalted butter
  • 2 tsp light corn syrup optional, adds shine
  • 1/4 tsp salt

Instructions
 

  • Preheat your oven to 350°F (175°C). Grease and line an 8-inch square baking pan with parchment paper for easy removal.
  • In a large bowl, whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt until evenly combined.
  • In a separate bowl, whisk the warm water, sour cream, vegetable oil, egg, vanilla extract, and espresso powder (if using) until smooth.
  • Gradually add the dry ingredients to the wet mixture, stirring until just combined. Avoid overmixing to keep the cake tender. Fold in the chocolate chips if desired.
  • Pour the batter into the prepared pan and bake for 28–32 minutes. A toothpick inserted should come out with a few moist crumbs.
  • Let the Chocolate Snack Cake cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
  • For the buttercream, beat the softened butter until creamy. Mix in cocoa powder, vanilla, and salt. Gradually add powdered sugar and heavy cream, then blend in melted chocolate until fluffy.
  • To make the ganache, heat the cream until steaming. Pour over chocolate chips, let sit for 1 minute, then stir until smooth. Mix in butter, corn syrup, and salt. Cool until slightly thickened.
  • Spread the buttercream over the cooled cake. Spoon the ganache on top and swirl gently with a knife.
  • Let the ganache set slightly before slicing. Serve with milk or coffee for the ultimate indulgence.

Notes

For a deeper chocolate flavor, use Dutch-process cocoa powder. Substitute sour cream with Greek yogurt if needed. Espresso powder is optional but intensifies the chocolate taste.
