How to Make Milk Chocolate Mousse Cake
-
Preheat the oven to 180°C (355°F) and prepare a 23cm (9″) cake tin. Grease the sides and line the base with parchment paper to ensure easy removal later.
-
Whisk together the cocoa powder, brewed espresso, and water in a medium saucepan over medium heat. Stir until steaming, then allow to cool for 10 minutes to achieve a rich chocolate base.
-
Sift and mix the dry ingredients, combining plain flour, bicarbonate of soda, and fine sea salt in a bowl. This step ensures even distribution of the leavening agents, which helps the cake rise beautifully.
-
Blend the eggs, Greek yogurt, and vegetable oil in a separate bowl. Once combined, gently fold in the dry ingredients, then incorporate the cooled cocoa mixture until smooth and well-mixed.
-
Pour the batter into the prepared tin, smoothing the top gently. Bake for about 35 minutes, or until a skewer inserted into the center comes out clean. The cake should have a delicate rise and a deep chocolate hue.
-
Cool the cake in the tin for a few minutes, then transfer it to a wire rack. Allow it to chill for at least 3 hours, or overnight, so it can firm up properly.
-
Level the top of the cooled sponge if desired, and place a ring mold around it to prepare for the mousse layer. This will help shape the mousse beautifully.
-
Bloom the gelatin in cold water according to package instructions. Meanwhile, heat the milk, cream, egg yolks, and sugar in a saucepan until thickened, reaching about 82-84°C (180-183°F).
-
Combine the hot mixture with the bloomed gelatin and milk chocolate, stirring until the chocolate melts completely and the mixture is smooth and glossy.
-
Fold in the whipped cream gently, being careful not to deflate it. Pour this delightful mousse over the sponge in the prepared mold. Refrigerate for 4-6 hours, or overnight, to allow it to set perfectly.
-
Serve by carefully removing the mold with gentle heat. Allow the mousse cake to warm slightly before slicing for easy serving.
Optional: Top with flaky sea salt for an added flavor boost!

Expert Tips for Milk Chocolate Mousse Cake

Milk Chocolate Mousse Cake Recipe FAQs
What type of cocoa powder should I use?
For the richest flavor, I recommend using Dutch-processed cocoa powder. It adds a deeper chocolate taste and darker color to your Milk Chocolate Mousse Cake, making it even more decadent. If you can’t find Dutch-processed, regular unsweetened cocoa powder will also work well.
How should I store the Milk Chocolate Mousse Cake?
To keep your cake fresh, store it covered in the refrigerator for up to 3 days. If you’d like to extend its life, consider freezing the assembled cake before applying the mousse. Wrap it tightly in plastic wrap and foil to prevent freezer burn.
Can I freeze the assembled cake with mousse?
Absolutely! To freeze, first chill the assembled Milk Chocolate Mousse Cake in the fridge. Once set, wrap it tightly with plastic wrap and then with aluminum foil. This will protect it from freezer burn. For best texture, consume within 3 months. When ready to enjoy, thaw it in the fridge overnight before serving.
What should I do if my mousse doesn’t set properly?
If your mousse doesn’t set, it may be due to undercooked egg yolks or insufficiently bloomed gelatin. Always ensure your mixture reaches the correct temperature (82-84°C/180-183°F) and follow blooming instructions on the gelatin packet. If it still doesn’t set, consider a possible adjustment of gelatin ratio for future attempts.
Are there any dietary considerations I should keep in mind?
Certainly! If you’re making the Milk Chocolate Mousse Cake for someone with allergies, be aware of possible sensitivities to eggs, dairy, or gluten. You can substitute with flax eggs for a vegan option or use almond milk for a lactose-free cake. Always check ingredient labels, especially with chocolate and cream, for allergens.
What if I want to use a different kind of chocolate for the mousse?
The more the merrier! You can easily swap half of the milk chocolate for dark chocolate if you prefer richer flavors. Just remember that the mousse might become slightly denser, so adjust your expectations for texture while maintaining the overall indulgence of the dessert!
