Servings: 1 9-inch tart
Calories: 359 kcal




1 1/4 cups almond flour

1/4 cup cocoa powder

1/4 cup powdered Swerve Sweetener

5 tbsp butter melted

Chocolate Mousse Filling:

3/4 cup whipping cream

3/4 cup unsweetened nut milk

1/4 cup butter

3 ounces good-quality unsweetened dark chocolate chopped (do not use sweetened chocolate here, as your mousse may not set properly)

3 tbsp cocoa powder

6 tbsp powdered Swerve Sweetener

1/2 tsp espresso powder optional, boosts chocolate flavor

3 large eggs


1 cup whipping cream

2 tbsp powdered Swerve Sweetener

1/4 tsp vanilla extract

1/2 ounce dark sugar-free chocolate

Fun Fact.


Turkey has become the traditional Thanksgiving fare because at one time it was a rare treat.

During the 1830s, an eight- to ten-pound bird cost a day’s wages. Even though turkeys are affordable today, they still remain a celebratory symbol of bounty.

In fact, astronauts Neil Armstrong and Edwin Aldrin ate roast turkey in foil packets for their first meal on the Moon. 



Lightly grease a 9-inch tart pan with a removable bottom.

In a medium bowl, whisk together the almond flour, cocoa powder, and sweetener. Add melted butter and stir until mixture clusters together.

Press firmly and evenly into the bottom and up sides of a prepared tart pan.

Refrigerate until filling is ready.

Chocolate Mousse:

In a small pan, combine cream, almond or cashew milk, and butter.

Bring to a full boil and then remove from heat.

In a blender, combine unsweetened chocolate, cocoa powder, sweetener, and espresso powder.

Pour in scalded cream mixture and blend until smooth.

Add eggs and blend again until smooth (*if you are concerned about the eggs, use pasteurized shell eggs such as Safest Choice).

Pour into chilled crust and chill until firm, at least 1 hour. Gently press the tart pan from bottom to remove the sides and place it on a serving platter.



Beat whipping cream with sweetener and vanilla until it holds stiff peaks.

Spread over mousse to the edges of the tart.

Using a cheese grater, shave the dark chocolate over the whipping cream.

Let sit a bit in the refrigerator before serving.
