For the Brownie Layer
- 1/2 cup Almond Flour
- 1/4 cup Cocoa Powder
- 1/3 cup Granular Erythritol
- 1/4 cup Butter, melted
- 1 large Egg
- 1/2 tsp Baking Powder
- 1/2 tsp Vanilla Extract
For the Chocolate Mousse
- 1 1/2 cups Heavy Whipping Cream
- 3 oz Sugar-Free Dark Chocolate, melted and cooled
- 3 tbsp Powdered Erythritol
- 1 tsp Vanilla Extract
For the Chocolate Pudding
- 1 cup Heavy Whipping Cream
- 2 large Egg Yolks
- 3 tbsp Cocoa Powder
- 3 tbsp Powdered Erythritol
- 1/2 tsp Vanilla Extract
For the Topping
- 1/2 cup Heavy Whipping Cream
- 1 tbsp Powdered Erythritol
- Sugar-Free Chocolate Shavings
How To Make
Step 1
Preheat oven to 350F and grease an 8×8 inch baking dish. Mix together the almond flour, cocoa powder, granular erythritol, melted butter, egg, baking powder, and vanilla extract until a thick batter forms. Spread into the dish and bake for 14 to 16 minutes until set. Let cool completely, then cut into small cubes.
Step 2
For the chocolate pudding, whisk the egg yolks, cocoa powder, and powdered erythritol together in a small saucepan. Pour in the heavy whipping cream and whisk until smooth.
Cook over medium-low heat, stirring constantly, for about 5 to 6 minutes until the mixture thickens enough to coat the back of a spoon. Remove from heat, stir in vanilla extract, and let cool completely.
Step 3
For the chocolate mousse, beat the heavy whipping cream with powdered erythritol and vanilla extract until soft peaks form. Drizzle in the melted and cooled dark chocolate while beating on low, then increase speed to medium-high and beat until stiff peaks form.
Step 4
Begin assembling the trifle in a large glass trifle dish or individual serving glasses. Place a layer of brownie cubes on the bottom, then spoon a layer of chocolate pudding over them.
Step 5
Add a thick layer of chocolate mousse on top of the pudding. Repeat the layers once more, ending with mousse on top.
Step 6
For the topping, whip the heavy whipping cream with powdered erythritol until stiff. Dollop or pipe it generously over the top of the trifle. Garnish with sugar-free chocolate shavings.
Step 7
Refrigerate for at least 2 hours before serving so the flavors meld and the brownie cubes soften slightly. This trifle tastes even better the next day.

Tips
Cool the Melted Chocolate Before Adding It
When you make the mousse, the melted dark chocolate needs to be cooled down to about room temperature before you drizzle it into the whipped cream. If it’s still warm, it will melt the whipped cream and deflate all the air you just beat into it.
After you melt the chocolate, just set it aside for about 10 minutes and give it a stir. It should feel barely warm to the touch before you use it.
Also, drizzle it in slowly while beating on low speed. If you dump it all in at once, you’ll get chunks of hardened chocolate instead of a smooth, even mousse.
Stir the Pudding Constantly on Low Heat
The pudding has egg yolks in it, so if you crank up the heat or stop stirring, you’ll end up with scrambled egg bits in your pudding. Keep the heat on medium-low and stir the whole time without stopping.

You’ll know it’s done when you can drag a spoon through it and the line holds for a second before filling back in. This takes about 5-6 minutes but don’t rush it by turning the heat up.
Once it’s off the heat, press a piece of plastic wrap directly onto the surface of the pudding while it cools. This prevents a thick skin from forming on top.
Use Powdered Erythritol for the Cream Layers
The recipe calls for powdered erythritol in the mousse, pudding, and topping for a reason. Granular erythritol won’t dissolve properly in these layers and you’ll end up with a gritty texture that’s really noticeable.
If you only have granular on hand, just blend it in a blender or spice grinder for about 30 seconds until it turns into a fine powder. It works perfectly.

Frequently Asked Questions
Can I use a different sugar-free sweetener instead of erythritol?
Yes, you can use other keto-friendly sweeteners like monk fruit sweetener or allulose. Just keep in mind that allulose is less sweet than erythritol, so you may need to add a bit more to get the same level of sweetness.
If you go with monk fruit blend, it usually works as a 1:1 swap for erythritol. Avoid using liquid sweeteners like stevia drops here because they won’t give you the same bulk and texture, especially in the brownie layer.
