How to Make the Recipe

Step 1: Preheat and Prep

Preheat your oven to 180°C (350°F). Grease a 15 x 9-inch pan with softened butter or vegetable oil.

Step 2: Prepare the Chocolate Base

Melt the butter over low heat. Whisk in half a chocolate bar until melted and smooth. Then add sugar and whisk until slightly grainy, about 2 minutes.

Step 3: Mix Wet Ingredients

Whisk in eggs, vanilla essence, and salt until the mixture is thick and uniform. Add milk and brewed coffee and whisk to combine.

Step 4: Combine Dry Ingredients

In a separate bowl, mix flour, baking powder, and cocoa powder. Sift into the wet ingredients and gently whisk until fully incorporated, about 3 minutes.

Step 5: Bake the Sponge

Pour the batter into the prepared pan and bake for 14–17 minutes, or until the edges begin to shrink from the pan. Let cool completely on a wire rack.

Step 6: Make the Ganache

Use the double boiler method to melt chocolate in heavy cream over low heat. Once fully melted, let cool for 30 minutes or refrigerate for 10 minutes. Then whip until the ganache is thickened and creamy.

Step 7: Assemble

Slice the cooled sponge cake into two equal layers. Spread whipped ganache over the bottom layer, sprinkle with nuts if desired, and place the top layer on. Press gently.

Step 8: Decorate

Drizzle with melted chocolate and sprinkle with remaining chopped nuts for a finished, elegant look.

Tips for Making the Recipe

Don’t overmix the batter to maintain a light, sponge-like texture.
Room temperature ingredients mix more smoothly and evenly.
Chill the ganache before whipping for better volume and consistency.
Use a serrated knife or a hot knife to slice clean petit fours.
For neater layers, weigh the sponge cake halves before frosting to ensure even height.

How to Serve

Brownie Petit Fours are best served chilled or at room temperature. Arrange on a dessert platter or serve in paper mini-cups for a refined presentation. They pair beautifully with coffee, espresso, or a glass of dessert wine for an upscale treat.

Make Ahead and Storage

Storing Leftovers

Store petit fours in an airtight container in the refrigerator for up to 5 days. Separate layers with parchment to avoid sticking.

Freezing

Freeze for up to 1 month. Wrap each piece in plastic wrap and store in a freezer-safe container. Thaw in the fridge overnight before serving.

Reheating

These are best served cold or room temp; reheating is not necessary and may affect texture.
