• Coconut Sugar – Sweetens the cake with a hint of caramel flavor; light brown sugar can replace it for a similar taste.
• Cacao Powder – Delivers the rich chocolate flavor essential in this mint chocolate cake; use unsweetened cocoa powder as an alternative if needed.
• Baking Soda – Helps the cake rise; ensure freshness for optimal results.
• Espresso Powder – Intensifies chocolate flavor; you can omit it for a caffeine-free option.
• Kosher Salt – Enhances overall flavors; feel free to use sea salt as a substitute.

• Water – Adjusts batter consistency; no substitution needed.
• Coconut Oil – Contributes to moisture and texture; can swap with vegetable oil or butter unless strictly avoiding them.

Step‑by‑Step Instructions for Mint Chocolate Mousse Cake
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While it warms up, prepare a 9-inch springform pan by greasing it and lining the bottom with parchment paper, ensuring an easy release once your Mint Chocolate Mousse Cake is ready to be served.
Step 2: Mix the Dry Ingredients
In a large mixing bowl, combine almond flour, tapioca flour, coconut flour, coconut sugar, cacao powder, baking soda, espresso powder, and kosher salt. Whisk these together until they are well combined and free of lumps, creating a light and airy mixture that will form the delightful base of your cake.
Step 3: Combine the Wet Ingredients
In a separate bowl, whisk together the egg, milk, water, coconut oil, apple cider vinegar, and vanilla extract. Ensure everything is well blended, then pour this mixture into the bowl of dry ingredients. Stir until a smooth batter forms, making sure no clumps remain for a perfectly consistent cake.
Step 4: Bake the Cake
Pour the prepared batter into your greased and lined springform pan, spreading it evenly. Place it in the preheated oven and bake for 12 to 14 minutes, or until the cake springs back gently when touched and a toothpick inserted comes out clean. Once done, remove it from the oven and let it cool completely.
Step 5: Prepare the Chocolate Mousse
While the cake cools, melt the chopped semisweet chocolate along with vanilla extract, peppermint extract, and a pinch of salt in a food processor. In a saucepan, heat 1 cup of heavy cream until it’s just boiling, then carefully drizzle it into the processing chocolate mixture while blending until it becomes silky smooth.
Step 6: Fold in the Whipped Cream
In a mixing bowl, whip 2 cups of heavy cream until stiff peaks form, which should take about 3-5 minutes. Gently fold this whipped cream into the chocolate mixture, ensuring you preserve that airy texture. This step creates the luxurious mousse that will top your Mint Chocolate Mousse Cake beautifully.
Step 7: Assemble the Cake
Once the cake has cooled, spread the luscious mint chocolate mousse over the top in an even layer, smoothing it with a spatula. Cover the cake with plastic wrap and place it in the refrigerator to chill for at least 6 hours or overnight, allowing the mousse to firm up and the flavors to meld deliciously.
Step 8: Make the Whipped Topping
When you’re ready to serve, whip additional chilled heavy cream with vanilla extract until medium peaks form, creating a fluffy texture. Transfer this whipped cream to a piping bag and pipe decorative swirls on top of the mousse layer, adding an elegant touch to your Mint Chocolate Mousse Cake.
Step 9: Garnish and Present
To finish off your masterpiece, sprinkle chocolate shavings over the whipped topping and add fresh mint leaves as a decorative garnish. These final touches bring visual appeal and an extra hint of minty freshness, making your cake as inviting as it is delicious.
Expert Tips for Mint Chocolate Mousse Cake
-
Ingredient Quality Matters: Use high-quality cocoa powder and semisweet chocolate for a richer flavor in your mousse. Cheap ingredients can result in a flat taste.

Whip Cream Properly: Ensure your heavy cream is very cold when whipping for the best results; this achieves that light, airy texture in the mousse and topping.
-
Chill Time: Don’t rush the chilling process! Allow the cake to chill for at least 6 hours, or overnight for optimal mousse firmness and flavor infusion.
-
Layering: For a more dramatic presentation, create a swirl effect with the mousse and whipped topping by alternating layers or piping them together.
-
Taste Test: Before serving, check for sweetness; the cake may need a light dusting of powdered sugar if you prefer extra sweetness in your mint chocolate mousse cake.

Reheating: If you’ve frozen slices, there’s no need to reheat—simply let them thaw, and enjoy the delightful flavors at room temperature, preserving that creamy mousse texture.

Mint Chocolate Mousse Cake Recipe FAQs
What type of mint is best to use in this cake?
Absolutely! For the freshest flavor, I recommend using peppermint extract, as it provides that delightful minty kick. If you prefer a more natural touch, you can also use fresh mint leaves in the mousse; simply chop them finely and fold them in for an extra layer of flavor.
How should I store my Mint Chocolate Mousse Cake?
You’ll want to keep it in the fridge to maintain its deliciousness! Cover the cake with a tight-fitting lid or plastic wrap, and it will stay fresh for up to 3 days. Just be sure to keep it chilled until serving.
Can this cake be frozen?
Very! To freeze your Mint Chocolate Mousse Cake, I suggest slicing it first for easy serving. Wrap each piece tightly in plastic wrap, then place them in an airtight container. It can be stored in the freezer for up to 2 months. When you’re ready to enjoy a slice, simply thaw it in the fridge overnight or let it sit at room temperature for about 30 minutes.
What should I do if my mousse doesn’t set properly?
If you find that your mousse isn’t setting as expected, don’t worry—this can happen! Make sure that your heavy cream was whipped to stiff peaks before folding it into the chocolate mixture. If your mousse still seems too soft, you can gently re-whip it and fold in a bit more whipped cream. Remember, chill time is also crucial, so don’t skip the recommended 6 hours in the fridge!
Can I make this cake dairy-free?
Absolutely! To make your Mint Chocolate Mousse Cake dairy-free, substitute regular milk with almond milk or coconut milk, and use coconut cream instead of heavy cream in your mousse. These swaps will give you the same dreamy texture without the dairy. Your dessert can still be indulgent and guilt-free!
