Ingredients:
- 4 oz (115 g) Dark Chocolate (85% cocoa minimum), finely chopped or chips
- 2 Tbsp (28 g) Unsalted Butter, softened
- 1 Tbsp (15 ml) Hot Espresso or strong coffee (or water)
- Pinch (approx. 1/8 tsp) Fine Sea Salt
- 1/4 cup (50 g) Granulated Keto Sweetener (Monk fruit/Erythritol blend)
- 1 1/2 cups (360 ml) Cold Heavy Cream (Double Cream)
- 1 tsp (5 ml) Pure Vanilla Extract
- Optional: 1 Tbsp (10 g) Confectioner's Keto Sweetener for dusting
Instructions:
- Melt the Chocolate: Place the chopped dark chocolate and butter into a heatproof bowl. Use a bain-marie or microwave in 30-second bursts, stirring until just melted and smooth. Do not overheat.
- Dissolve and Flavour: Stir in the hot espresso (or water), the pinch of salt, and the granulated keto sweetener until the sweetener is completely dissolved and the mixture is glossy.
- Cool Down: Set the chocolate base aside to cool. It must be cool to the touch (lukewarm at the absolute most) before folding, or it will deflate the cream.
- Prepare the Cream: Ensure your heavy cream is straight from the fridge—cold cream whips best. Pour the cold cream and vanilla extract into the bowl of your stand mixer.
- Whip to Stiff Peaks: Begin whipping on medium speed, gradually increasing to high. Continue until the cream forms firm, stiff peaks (it should hold its shape when the whisk is lifted). Be careful not to over-whip into butter!
- Lighten the Base: Take about one-third of the stiffly whipped cream and gently fold it into the cooled chocolate base mixture using a spatula. This process lightens the chocolate and makes the subsequent folding easier.
- Final Fold: Pour the lightened chocolate mixture over the remaining two-thirds of the whipped cream. Using a gentle 'cut and fold' motion, incorporate the chocolate mixture into the cream. Stop as soon as no streaks of white cream remain. Do not overmix, or the mousse will become heavy.
- Portion and Chill: Spoon or pipe the mousse equally into four ramekins or serving glasses.
- Set Up: Cover lightly and chill in the refrigerator for a minimum of 2 hours, or ideally, 4 hours, to allow the butter and cocoa solids to set the mousse perfectly.
- Serve: Garnish just before serving with shaved chocolate or a dusting of confectioner's keto sweetener.
