Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

1 1/2 cups heavy cream or 1 can full-fat coconut milk
1/4 cup unsweetened cocoa powder
1 tablespoon additional cocoa powder (regular or Dutch-processed)
1/4 cup powdered or granulated keto-friendly sweetener
1/2 teaspoon pure vanilla extract (optional)
1/4 teaspoon instant coffee (optional)

Directions

If using heavy cream, ensure it is very cold. If using coconut milk, refrigerate the can overnight and scoop out only the thick cream from the top, leaving the liquid behind.
Place the cold cream into a large mixing bowl. For best results, chill the bowl beforehand.
Using a hand mixer or stand mixer, whip the cream until stiff peaks begin to form.
Add the cocoa powder, additional cocoa, and sweetener. Continue whipping until fully combined and thickened into a mousse-like texture.
Stir in vanilla extract and instant coffee if using.
Taste and adjust sweetness if needed.
Serve immediately for a soft, airy texture or refrigerate for 30–60 minutes for a firmer mousse.

Servings and timing

Servings: 3 to 4 servings
Prep time: 5 minutes
Chill time: 30 to 60 minutes (optional)

Variations

Mocha chocolate mousse: Increase the instant coffee slightly for a deeper mocha flavor.

Dairy-free version: Use full-fat coconut cream instead of heavy cream for a completely dairy-free dessert.

Extra rich mousse: Add a tablespoon of softened cream cheese and whip until smooth for an even thicker texture.

Spiced chocolate: Add a pinch of cinnamon or a tiny dash of chili powder for a subtle warmth.

Chocolate orange: Mix in a small amount of orange zest for a bright citrus twist.

Storage/Reheating

Store leftover mousse in an airtight container in the refrigerator for up to 3 days. The texture may firm up slightly as it chills. Simply stir gently before serving to restore creaminess.

This mousse is not ideal for reheating, as heat will cause it to lose its whipped structure. It is best enjoyed cold straight from the refrigerator.

FAQs

Can I make this mousse ahead of time?

What sweetener works best for keto mousse?

Why isn’t my mousse thickening?

Make sure your cream is very cold and that you whip it long enough to form stiff peaks before adding other ingredients.

Can I freeze chocolate mousse?

Freezing is not recommended because it can change the texture once thawed.

Is this recipe dairy-free?

It can be made dairy-free by using full-fat coconut cream instead of heavy cream.

How can I make the flavor more intense?

How long does it last in the fridge?
