Ingredients

• 3 medium ripe avocados, pitted and scooped (about 1 1/2 cups flesh)
• 1/2 cup unsweetened cocoa powder
• 1/2 cup heavy cream, cold
• 1/3 cup powdered erythritol sweetener
• 1 tsp vanilla extract
• 1/4 tsp fine salt
• 2 tbsp unsweetened almond milk (only if the blender stalls)

Instructions

1. Process the avocado flesh in a food processor for 30 seconds, scraping down the sides, until no chunks remain.
2. Add the cocoa powder, sweetener, salt, and vanilla and process a full minute; scrape the bowl — hidden streaks of avocado are the enemy here.
3. With the machine running, pour in the cold heavy cream and whip 1-2 minutes, until the mousse turns noticeably lighter, glossy, and holds a soft peak. Add the almond milk only if the mixture stalls in the processor.
4. Taste and adjust sweetener — avocado ripeness varies, so this is the step that makes it dessert instead of guacamole.
5. Spoon into 4 small glasses or ramekins, smoothing the tops with the back of a spoon.
6. Serve immediately, or press plastic wrap onto the surface and chill 30 minutes for a firmer, fudgier set. Top with whipped cream just before serving.

Why this recipe works

• Ten minutes flat One food processor and 10 minutes, and dessert is sitting in glasses. No stove, no oven, and no waiting unless you want a firmer set.
• Avocado as the base Ripe avocados give the mousse its body, which is why there is no gelatin anywhere in the ingredient list. Cocoa and vanilla handle the flavor; the fruit handles the texture.
• Cold cream, real whip Heavy cream poured in while the blade runs turns the mixture lighter, glossy, and peak-holding. That whipping minute is what separates mousse from chocolate spread.

Tips for making this recipe well

Process the avocado alone first

Thirty seconds by itself, scrape, then again until no chunks remain. Chunks that survive this step haunt the finished mousse.

Hunt the hidden streaks

After the cocoa goes in, process a full minute and scrape the bowl. Green streaks against dark chocolate are easy to miss and hard to ignore on a spoon.

Taste before you portion

Avocado ripeness swings a lot, so sweeten by taste. This is the step that turns the bowl into dessert rather than guacamole.

Milk only if it stalls

The almond milk is a rescue, not an ingredient. A thick processor load whips fine without it and sets fudgier.

Serving suggestions

Spoon it into four small glasses and smooth the tops with the back of a spoon, then add whipped cream right before they reach the table. It reads like a chocolate shop dessert and costs 4.0g net carbs a jar. For a firmer, fudgier set, press plastic wrap onto the surface and give it 30 minutes in the fridge. A pinch of flaky salt on the cream does no harm.

Storage and meal prep

This is a same-day dessert by nature. Pressed plastic wrap against the surface slows the browning, and a night in the fridge costs a shade of color but nothing else, so plan to finish it within a day or two. Keep it cold at all times, since the whipped cream base weeps as it warms. Make it before dinner, not on Sunday for the week.

Variations worth trying

• Mocha Dissolve a teaspoon of instant espresso into the cream before it goes in.
• Mint Two drops of peppermint extract and a few extra minutes of chilling.
• Coconut Swap the cream for cold coconut cream and top with toasted coconut flakes.

Frequently asked questions

Will it taste like avocado?

Not once the cocoa, vanilla, and sweetener are balanced, which is why the tasting step exists. Under-sweetened mousse is the only version that reads green.

Can I use a blender instead?

A food processor is the better tool because the blade pulls the thick base down and around. If a blender is what you have, expect more stopping and scraping, and use the almond milk.

How ripe should the avocados be?

Ripe enough that your thumb sinks easily, with no brown strings inside. Under-ripe fruit stays chunky and bitter; overripe fruit tastes off.

Why is mine bitter?

Cocoa powder is bitter by design, and sweetness is the counterweight. Add powdered erythritol a tablespoon at a time and taste after each.

Can I make it ahead for a party?

Morning-of works well: portion into glasses, press the wrap onto the surface, and chill. By dessert the set is firmer and the color has held.
