- 1 teaspoon vanilla extract
- 1 teaspoon baking powder
- ½ teaspoon salt
- ½ cup dairy-free dark chocolate chips (optional)
For the Chocolate Mousse:
- 1 ½ cups coconut cream (scooped from the top of a chilled can of full-fat coconut milk)
- 1 cup dairy-free dark chocolate, melted
- ¼ cup maple syrup (or agave syrup)

Step-by-Step Instructions
1. Prepare the Brownie Base
Preheat your oven to 350°F (175°C) and line an 8-inch round or square baking pan with parchment paper, allowing some overhang for easy removal.
Make the flax egg by mixing the ground flaxseed with 3 tablespoons of water. Let it sit for 5-10 minutes until it thickens and forms a gel-like consistency.
In a large mixing bowl, whisk together the almond flour, cocoa powder, coconut sugar, baking powder, and salt. In a separate bowl, combine the melted coconut oil, almond milk, flax egg, and vanilla extract.
Pour the wet ingredients into the dry mixture and stir until well combined. The batter will be thick but smooth. If you’re adding chocolate chips, fold them in now for extra fudginess!
Spread the brownie batter evenly into the prepared pan. Bake for 18-22 minutes, or until the edges are set, and a toothpick inserted in the center comes out with a few moist crumbs.
Let the brownie cool completely in the pan before adding the mousse layer. You can speed up the process by placing the pan in the fridge or freezer for 20-30 minutes.
2. Make the Chocolate Mousse
While the brownie base cools, you can start on the mousse layer.
In a microwave-safe bowl or using a double boiler, melt the dairy-free dark chocolate until smooth. Let it cool slightly before using.
In a large mixing bowl, whip the coconut cream using an electric mixer until it becomes light and fluffy, about 2-3 minutes. Be sure to only use the thick part of the coconut cream and avoid the watery liquid at the bottom of the can.
Add the melted chocolate, maple syrup, vanilla extract, and a pinch of salt to the whipped coconut cream. Continue whipping until everything is well combined, smooth, and fluffy.
3. Assemble the Cake
Once the brownie layer is completely cooled, spread the chocolate mousse evenly on top. Use a spatula to create swirls or a smooth finish, depending on your preference. For a bakery-style look, pipe some decorative swirls on top using a piping bag.
Refrigerate the assembled cake for at least 2 hours, or until the mousse has fully set and is firm to the touch.
4. Garnish and Serve
Before serving, top the cake with dairy-free chocolate shavings, chunks, or fresh berries for a pop of color. For a bit of crunch, chopped nuts like almonds or hazelnuts work beautifully.
Slice and enjoy! This cake pairs perfectly with a scoop of vegan ice cream or a drizzle of homemade chocolate sauce.
Tips for Success
- Coconut Cream Tip: Ensure your can of coconut milk is well-chilled to get the thick, creamy portion separated from the liquid. It’s best to refrigerate it overnight.
- Flax Egg Substitute: If you don’t have flaxseed, you can use a chia seed egg (same ratio as the flax) or a store-bought egg replacer.
- Sweetener Options: If you’re not strictly paleo, you can use regular cane sugar or brown sugar instead of coconut or maple sugar. For a sugar-free version, try using a stevia blend or monk fruit sweetener.
- Chocolate Choices: Opt for a high-quality dairy-free dark chocolate for the mousse to achieve the richest flavor. The better the chocolate, the more decadent your mousse will be!

Storage and Serving Tips
- Refrigeration: This cake keeps best in the refrigerator. Store it in an airtight container for up to 5 days. The mousse will stay light and fluffy, and the brownie layer will remain chewy.

- Serving Suggestions: For a complete dessert experience, serve this cake with fresh fruit, a dollop of whipped coconut cream, or a dusting of cocoa powder on top. A hot cup of coffee or tea also makes the perfect pairing.
