Place the cooked sweet potato and peanut butter in a food processor. Process until smooth and, then add the cacao powder, maple syrup, and orange zest. Blend again until smooth.
Place the chickpea brine in a clean bowl. Add the lemon juice and beat with a hand mixer until you achieve stiff peaks – this can take up to 5 or 6 minutes, depending on the power of the mixer.
Fold the whipped chickpea brine into the chocolate and mix until well combined. The mixture will deflate slightly.
Spoon the mousse between 4 small serving glasses and place in the fridge for 8 hours (or overnight) to set.
Notes
This mousse delivers over 7 grams of fibre per serve – more than most breakfast cereals! That makes it a dessert that genuinely supports digestion, satiety, and stable energy.
