How to Make Blackout Cake?

Step 1: Preparing the Cake Batter

  • Preheat your oven to 375�F and butter and lightly flour two 8-inch round cake pans.
  • In a small bowl, whisk together cocoa powder and boiling water until it forms a paste.
  • In a saucepan over medium heat, combine chopped unsweetened chocolate and milk. Stir frequently until the chocolate melts, then remove from heat.
  • Whisk a small amount of the hot chocolate milk into the cocoa paste to warm it, then combine it with the remaining milk mixture. Return the pan to medium heat and stir for one minute. Set aside to cool.

Step 2: Mixing the Batter

  • In the bowl of a mixer, cream together softened butter and sugar. Beat in the egg yolks, one at a time, and vanilla extract.
  • Slowly stir in the chocolate mixture.
  • In a separate bowl, combine flour, baking powder, baking soda, and salt. Gradually add this mixture to the chocolate mixture, folding it in until just mixed.
  • In another bowl, whisk the egg whites until soft peaks form, then gently fold them into the batter.

Step 3: Baking the Cakes

  • Divide the batter evenly between the prepared cake pans.
  • Bake in the preheated oven for 35 to 45 minutes, or until a toothpick inserted in the center comes out clean.
  • Allow the cakes to cool in the pans on a rack for 15 minutes, then gently remove them from the pans to cool completely.

Step 4: Making the Filling and Frosting

  • While the cakes are baking, prepare the filling by combining cocoa and boiling water in a small saucepan. Stir in sugar and chocolate, then add dissolved cornstarch paste and salt. Boil for one minute, then remove from heat and whisk in vanilla and butter. Refrigerate until cool and thick.
  • For the frosting, melt chocolate in a double boiler over hot water, then whisk in butter, hot water, corn syrup, and vanilla. Refrigerate until spreadable consistency.

Step 5: Assembling the Cake

  • Slice each cake layer horizontally in half to form four layers.
  • Place one layer on a cake round or plate and generously swath it with half of the filling. Add the second layer and repeat. Place the third layer on top.
  • Quickly apply a thin layer of frosting to the top and sides of the cake. Refrigerate for 10 minutes.
  • Meanwhile, crumble the remaining cake layer and set aside.
  • Apply the remaining frosting to the cake, then sprinkle it liberally with the cake crumbs.
  • Refrigerate for at least 1 hour before serving.

Some Things to Keep in Mind!

  1. Quality Cocoa Powder: Use high-quality Dutch-process cocoa powder for a rich chocolate flavor that truly shines through in every bite.
  2. Proper Chocolate Melting: When melting chocolate for the cake and filling, do so gently over low to medium heat, stirring continuously until smooth to avoid burning.
  3. Room Temperature Ingredients: Ensure your butter and eggs are at room temperature before beginning. This helps achieve a smoother batter and better incorporation of ingredients.
  4. Folding Egg Whites: When folding the whipped egg whites into the batter, do so gently and in batches to maintain the lightness of the cake.
  5. Even Cake Layers: To ensure evenly baked cake layers, rotate the pans halfway through baking and use a toothpick inserted into the center to check for doneness.
  6. Thickening the Filling: Allow the filling mixture to cool until it reaches a thick consistency before spreading between the cake layers. This ensures a stable and delicious filling.
  7. Chilling the Frosting: Refrigerate the frosting until it’s spreadable but not too firm. This makes it easier to work with when assembling the cake.
  8. Assembly and Refrigeration: After assembling the cake with the filling and frosting, refrigerate it for at least an hour before serving. This allows the flavors to meld together and makes for easier slicing.
