 * ¼ cup (25g) unsweetened cocoa powder

 * ½ cup (100g) granulated sugar

 * ½ tsp baking powder

 * ¼ tsp baking soda

 * ⅛ tsp salt

 * 1 large egg (room temperature)

 * ¼ cup (60ml) milk

 * 2 tbsp vegetable oil

 * 1 tsp vanilla extract

 * 3 tbsp hot water (or hot brewed coffee for extra flavor!)

2. For the Mousse Layers

 * 3 cups (720ml) heavy whipping cream (divided into three 1-cup portions)

 * 4 oz (115g) Dark Chocolate (60–70% cacao, finely chopped)

 * 4 oz (115g) Milk Chocolate (finely chopped)

 * 4 oz (115g) White Chocolate (good quality, finely chopped)

 * 1½ tsp powdered gelatin (divided: ½ tsp per layer)

 * 3 tbsp cold water (divided: 1 tbsp per layer)

👩‍🍳 INSTRUCTIONS

STEP 1: Make the Cake Base

 * Preheat your oven to 350°F (175°C). Grease a 8-inch or 9-inch springform pan and line the bottom with parchment paper.

 * In a medium bowl, whisk together the flour, cocoa powder, sugar, baking powder, baking soda, and salt.

 * Add the egg, milk, oil, and vanilla extract. Whisk until smooth.

 * Stir in the hot water (or coffee) until the batter is thin and well combined.

 * Pour into your pan and bake for 13–15 minutes (a toothpick inserted in the center should come out clean).

 * Cool completely in the pan.

STEP 2: Dark Chocolate Mousse (Layer 1)

 * Bloom Gelatin: Sprinkle ½ tsp gelatin over 1 tbsp cold water in a small bowl. Let stand for 5 minutes.

 * Melt the chopped dark chocolate in a heatproof bowl set over a pot of simmering water (or microwave in 20-second bursts), stirring until smooth. Melt the bloomed gelatin into the hot chocolate. Let cool slightly.

 * Whip 1 cup of heavy cream to soft peaks.

 * Gently fold ⅓ of the whipped cream into the dark chocolate mixture to lighten it, then fold in the remaining cream until smooth and uniform.

 * Pour over the cooled cake base, smooth the top with a spatula, and freeze for 15–20 minutes to set.

STEP 3: Milk Chocolate Mousse (Layer 2)

 * Repeat the exact same process as above using the milk chocolate, ½ tsp gelatin (bloomed in 1 tbsp cold water), and 1 cup of heavy cream.

 * Pour the milk chocolate mousse gently over the chilled dark chocolate layer.

 * Return to the freezer for 15–20 minutes to set.

STEP 4: White Chocolate Mousse (Layer 3)

 * Repeat the process once more using the white chocolate, ½ tsp gelatin (bloomed in 1 tbsp cold water), and the final 1 cup of heavy cream.

 * Pour over the milk chocolate layer and smooth out the top evenly.

STEP 5: Chill & Serve

 * Cover the pan loosely with plastic wrap and refrigerate for at least 4–6 hours (overnight is best!).

 * To unmold: Run a thin, sharp knife dipped in hot water around the inside rim of the pan before opening the springform latch.

 * Top with cocoa powder, chocolate curls, or fresh berries! 🍓✨

💡 PRO TIPS FOR SUCCESS

 * Use Real Chocolate Bars: Avoid chocolate chips for mousse if possible—baking bars melt much smoother and give a better texture.

 * Gelatin Secret: The gelatin ensures clean, distinct layers when sliced, but make sure not to let your melted chocolate get too cold before folding in the cream, or it will seize.

 * Hot Knife Trick: Wipe your knife clean and dip it in hot water between every slice for picture-perfect cake slices!
