5-Ingredient Chocolate Chia Mousse (No Cook)
This chocolate chia mousse is the kind of dessert that feels like a treat but takes almost no effort. With just five ingredients and a few minutes of stirring, you get a creamy, spoonable chocolate pudding that sets up in the fridge overnight.
It’s rich from cocoa, naturally sweetened with maple syrup, and thick enough to hold its shape in a bowl. Make it before bed and wake up to a ready-to-eat dessert.
What Makes This Mousse So Good
The texture lands right where I want it: thick and velvety, not gloppy. Chia seeds soak up the milk and turn into tiny pearls suspended in a dark, fudgy base.
No cooking, no blender required (unless you prefer it super smooth). It’s the dessert I reach for when I want something that tastes like a chocolate truffle in pudding form.
I’ve made it with everything from oat milk to coconut cream, and it always works. The hardest part is waiting for it to chill.
Ingredients
- 1/2 cup chia seeds: these thicken as they absorb liquid; any color works
- 1/4 cup unsweetened cocoa powder: use Dutch-process for a deeper, less acidic taste, or natural cocoa works too
- 1 1/2 cups milk of choice: dairy or non-dairy; whole milk or full-fat coconut milk gives the richest result
- 3 tablespoons maple syrup: or agave nectar; adjust to your sweetness preference
- 1 teaspoon vanilla extract: pure vanilla, not imitation
- Pinch of fine sea salt: (optional): draws out the chocolate flavor
Variations / Substitutions
- Sweetener swap: use honey, date syrup, or a liquid sugar alternative like monkfruit syrup. Granulated sugar might not dissolve smoothly.
- Chocolate upgrade: swap half the cocoa powder for melted dark chocolate stirred in with the milk for a more intense chocolate flavor.
- Milk choice: coconut milk from a can yields a thick, almost mousse-like texture; oat milk makes it a bit lighter. Avoid watery milks like rice milk.
- Add-ins: fold in a tablespoon of espresso powder or a pinch of cinnamon before chilling for a mocha or spiced twist.

How to Make Chocolate Chia Mousse
Step 1: Mix the Dry Ingredients
In a medium bowl, whisk together the 1/2 cup chia seeds, 1/4 cup cocoa powder, and a pinch of salt if using until no cocoa lumps remain.
Step 2: Whisk in the Liquids
Pour in the 1 1/2 cups milk, 3 tablespoons maple syrup, and 1 teaspoon vanilla. Whisk thoroughly for about 30 seconds until the mixture looks like thin chocolate milk and no dry specks of cocoa are visible. Let the bowl sit on the counter for 10 minutes (this gives the chia seeds a head start), then give it another vigorous whisk to distribute any seeds that have started to clump. Cover and refrigerate for at least 4 hours, preferably overnight.
Step 3: Stir and Serve
When the mousse is thick and set, give it a good stir. Spoon it into small glasses or bowls and top with whatever you like: a cloud of whipped cream, shaved dark chocolate, fresh raspberries, or a drizzle of extra maple syrup. Serve chilled.
Tips for the Creamiest Mousse
- Blend for a smooth finish: If you prefer a mousse without the slight crunch of chia seeds, blitz the mixture with an immersion blender after the 10-minute rest, then refrigerate. It will set to a pudding-like smoothness.
- Sweeten to taste: Taste the liquid before chilling and add more maple syrup if you like a sweeter dessert. The chia seeds absorb sweetness, so it’s easier to adjust now.
- Fix a too-thin mousse: If your mousse hasn’t set after 4 hours, stir in an extra tablespoon of chia seeds and wait another hour.
- Skip the cocoa clumps: Whisking the cocoa with a tiny splash of the milk first to make a paste, then adding the rest of the milk, can prevent stubborn cocoa lumps.

Storing Leftover Mousse
This mousse keeps beautifully. Spoon leftovers into a covered jar or container and refrigerate for up to 5 days. It will thicken a little more as it sits, so give it a stir before spooning into bowls. Serve it cold—no reheating needed.
What to Serve With Chocolate Chia Mousse
A bowl of this mousse is lovely on its own, but a few pairings turn it into a full dessert. A shot of espresso alongside cuts the richness, while a spoonful of tart crème fraîche or Greek yogurt on top adds a tangy contrast. For crunch, scatter toasted coconut flakes or crushed biscotti over the top just before digging in.
Frequently Asked Questions
Can I use water instead of milk?
No, water will produce a much thinner, less creamy texture. Stick with milk or a creamy plant-based alternative for the best result.
Is this recipe vegan and gluten-free?
Yes, as long as you use a plant-based milk and check that your cocoa powder and sweetener are vegan/gluten-free. It’s naturally free of both.
Can I make this without vanilla extract?
Yes, you can omit it, though the flavor will be a bit flatter. A drop of almond extract or a pinch of espresso powder can fill that gap.
Can I freeze this mousse?
Freezing isn’t recommended; the texture becomes icy and grainy once thawed. It keeps well in the fridge, so make what you’ll eat within 5 days.
