Eggless Chocolate Mousse Cake | Triple Layer Chocolate Pastry | Eggless Chocolate Cake Recipe
Eggless Chocolate Mousse Cake is a delicious triple-layer chocolate pastry featuring a moist spongy chocolate base, a light creamy chocolate mousse middle, and a glossy chocolate ganache top. This version uses no eggs, no butter, no gelatin and is simple enough for beginner bakers. It yields a super-moist cake ideal for birthdays, celebrations or whenever you crave a rich chocolate dessert. A video demonstration is available on YouTube for visual reference.
Why sieve dry ingredients?
Sifting the flour and cocoa prevents lumps and helps the batter stay light. Over-mixing lumpy batter often produces a dense cake, so sieve the dry ingredients before combining.
Microwaving or stovetop for ganache?
You can heat heavy cream either in a microwave until hot or on the stovetop just until it begins to simmer. Add the chocolate chips to the hot cream and stir until smooth. If the chips don’t fully melt, warm briefly again in short intervals.
Can I bake the cake on the stovetop (in a pan)?
Yes. Preheat a large pan with a stand inside for 10 minutes over medium heat. Place the cake pan on the stand, cover with a tight lid and cook on low for 30–40 minutes, or until a toothpick inserted in the center comes out clean.
Should I refrigerate the cake?
Yes. Refrigeration improves shelf life and helps the mousse and ganache set properly. Chill the cake after adding the mousse layer for best texture.
About the chocolate ganache
Make the ganache by heating heavy cream and pouring it over chocolate chips, then stirring until smooth. Let it cool to room temperature before using. For the mousse layer the ganache should be fully cooled; for a flowing top ganache you can prepare that layer after the mousse has chilled for 12 hours.
Can I cut the cake immediately after adding ganache?
You can slice the cake, but give the ganache a few hours to set for cleaner slices. In this recipe the mousse is chilled for 12 hours before adding the final ganache, and the finished cake is chilled another few hours before serving.
Substitutions and tips
- Wheat flour: Using wheat flour can make the cake denser. If you substitute, use finely ground wheat flour, add 2–3 tbsp extra water and brush the layers with chocolate or simple syrup to keep them moist.
- Oil vs butter: Neutral-flavored oil keeps this eggless cake very moist. You may substitute melted unsalted butter if preferred, but oil gives excellent texture in eggless recipes.
- Coffee decoction: A small amount of coffee enhances chocolate flavor but is optional. It will not make the cake taste like coffee.
- Chocolate syrup: Optional for extra flavor and moisture between layers.

How to make Eggless Chocolate Mousse Cake
Bake the chocolate cake
- Preheat the oven to 350°F (175°C). If cooking in a pan, preheat the pan and stand for 10 minutes on medium heat.
- Line a cake pan with parchment and lightly grease it.
- Sift together the all-purpose flour, cocoa powder, baking powder and baking soda until lump-free. Stir in a pinch of salt.
- In a separate bowl combine sugar, vanilla, oil, water, vinegar and coffee decoction. Add the wet ingredients to the dry and fold gently until combined. Avoid over-mixing.
- Pour batter into the pan, tap gently to release any air bubbles and bake 30–40 minutes, or until a toothpick inserted in the center comes out clean. If baking on the stovetop, place the cake pan on the heated stand, cover and cook 30–40 minutes on low.
- Let the cake rest 5 minutes, then unmold and cool completely.
Prepare the chocolate ganache
- Heat 3/4 cup heavy cream until very hot (1 minute in a microwave or until it simmers gently on the stove).
- Pour over the chocolate chips, stir until smooth and allow to cool to room temperature.
Make the eggless chocolate mousse
- Whip 3/4 cup heavy cream in a wide bowl until soft peaks form.
- Gently fold in 3/4 cup of the cooled chocolate ganache and 1/4 cup powdered sugar until smooth and airy.
- Chill the mousse in the refrigerator to help it set before assembling the cake (12 hours recommended for best texture).
Assemble the cake
- Place the cooled cake back in the pan or on a serving plate. Use a toothpick to prick the top all over.
- Mix the chocolate syrup with water and brush or pour evenly over the cake to add moisture.
- Spoon and spread the entire mousse layer over the cake, smoothing it evenly.
- Refrigerate the cake with the mousse layer for at least 12 hours so it firms up.
Finish with the ganache layer
- Gently warm 1/3 cup heavy cream, pour over the leftover ganache and mix until smooth. Optionally add 1 tbsp powdered sugar to sweeten.
- Let this ganache cool slightly, then pour over the chilled mousse layer and spread around the top and sides.
- Chill for another 2–3 hours so the final ganache sets. Optionally sprinkle grated chocolate before serving.
Notes and tips
- Chocolate syrup between layers keeps the cake extra moist and chocolatey but is optional.
- Avoid over-mixing the batter to keep the cake light and tender.
- Let ganache cool before combining with whipped cream or adding to the cake.
- Use chilled heavy cream for whipping to help the mousse stabilize.
- If you replace chocolate chips with a chocolate bar, chop it finely for easier melting.
- Refrigerate the cake at least 12 hours after adding the mousse layer and 2–3 hours after the final ganache for best results.
