Mix the dry ingredients: In a medium bowl or large measuring cup, whisk together 3 tablespoons chia seeds, 2 tablespoons unsweetened cocoa powder, 2–3 tablespoons keto sweetener, and a small pinch of salt.
Break up any cocoa clumps with the whisk.
Add the liquids: Pour in 3/4 cup unsweetened almond milk and 1/4 cup heavy cream (or use 1 cup almond milk for dairy-free). Add 1 teaspoon vanilla extract. If using, stir in 1/4 teaspoon espresso powder.
Whisk thoroughly: Whisk for a full 45–60 seconds.
You want every chia seed coated so it doesn’t clump. The mixture should look smooth and evenly colored.
Rest briefly, then whisk again: Let the mixture sit for 5 minutes, then whisk once more to break up any settling. This simple step ensures a smooth set.
Chill to set: Cover and refrigerate for at least 1–2 hours, or overnight for best thickness.
It will continue to firm as it chills.
Adjust consistency: If it’s thicker than you like, whisk in a splash of almond milk. If it’s too loose, stir in an extra teaspoon of chia seeds and chill 10–15 more minutes.
Finish and serve: Taste and adjust sweetness. Spoon into bowls or jars and add toppings like whipped cream, raspberries, or cacao nibs.
Serve cold.
