Heavenly Raspberry Chocolate Mousse Cake Recipe
Introduction
This Heavenly Raspberry Chocolate Mousse Cake is a decadent treat that combines rich chocolate layers with a light, fruity mousse. Perfect for special occasions or anytime you want an elegant dessert that’s surprisingly easy to make.

Ingredients
- 1 cup all-purpose flour
- 1/2 cup unsweetened cocoa powder
- 1 cup granulated sugar
- 1 tsp baking powder
- 2 large eggs
- 1/2 cup vegetable oil
- 1/2 cup whole milk
- 1 cup fresh raspberries
- 1 cup dark chocolate chips
- 1 tsp agar-agar powder
Instructions
- Step 1: Preheat the oven to 350°F (175°C) and grease two round cake pans.
- Step 2: In a bowl, whisk together the flour, cocoa powder, sugar, and baking powder.
- Step 3: In a separate bowl, mix the eggs, vegetable oil, and milk until frothy. Combine with the dry ingredients and stir until just mixed.
- Step 4: Divide the batter evenly between the prepared pans and bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Let the cakes cool completely.
- Step 5: Melt the dark chocolate chips gently. In a small saucepan, heat the fresh raspberries with agar-agar powder until the agar-agar dissolves. Mix the melted chocolate with the raspberry mixture to create a smooth mousse.
- Step 6: Assemble the cake by placing one cake layer on a serving plate. Spread half of the raspberry chocolate mousse over it, then top with the second cake layer. Finally, spread the remaining mousse on top of the cake.
Tips & Variations
- Use frozen raspberries if fresh are not available, but thaw and drain excess liquid before use to avoid a watery mousse.
- For extra richness, fold whipped cream into the raspberry chocolate mixture before layering.
- Substitute agar-agar with gelatin if preferred, following package instructions for setting quantities.

FAQs
Can I make this cake ahead of time?
Yes, you can prepare the cake layers and mousse a day ahead. Assemble the cake and keep it refrigerated until ready to serve to allow the mousse to set properly.
What if I don’t have agar-agar powder?
You can substitute agar-agar with an equal amount of powdered gelatin. Bloom the gelatin in a little cold water before heating it gently to dissolve, then mix with the raspberry puree and chocolate as directed.

Ingredients
For the Cake Layers
- 1 cup all-purpose flour
- 1/2 cup unsweetened cocoa powder
- 1 cup granulated sugar
- 1 tsp baking powder
- 2 large eggs
- 1/2 cup vegetable oil
- 1/2 cup whole milk
For the Raspberry Chocolate Mousse
- 1 cup fresh raspberries
- 1 cup dark chocolate chips
- 1 tsp agar-agar powder
Instructions
- Preheat and Prepare Pans: Preheat your oven to 350°F (175°C) and grease two round cake pans to prevent sticking, ensuring easy cake removal after baking.
- Mix Dry Ingredients: In a large bowl, whisk together the all-purpose flour, unsweetened cocoa powder, granulated sugar, and baking powder until well combined and free of lumps.
- Combine Wet Ingredients: In a separate bowl, beat the eggs with vegetable oil and whole milk until frothy and smooth, then gradually incorporate the dry ingredients, mixing just until combined to maintain a light texture.
- Bake the Cake Layers: Divide the batter evenly between the prepared pans and bake for 25 to 30 minutes. Check doneness by inserting a toothpick into the center; it should come out clean. Allow cakes to cool completely before assembling.
- Prepare the Mousse: Gently melt the dark chocolate chips over a double boiler or in short bursts in the microwave. In a small saucepan, warm the fresh raspberries with agar-agar powder until the agar-agar dissolves completely, then combine the raspberry mixture with melted chocolate to create a smooth mousse.
- Assemble the Cake: Place one cake layer on your serving plate and spread half of the raspberry chocolate mousse evenly over it. Top with the second cake layer, then spread the remaining mousse on top, smoothing the surface for an elegant finish.
Notes
- Use fresh raspberries for best flavor and texture in the mousse.
- Ensure cakes are completely cooled before applying mousse to prevent melting.
- Agar-agar serves as a vegan-friendly gelatin substitute to set the mousse.
- You can refrigerate the assembled cake for 1-2 hours to firm up the mousse before serving.
- For a richer cake, substitute whole milk with buttermilk or add a teaspoon of vanilla extract to wet ingredients.
