Ingredients
- Almond crumb
- 3 tbsp unsalted butter
- 1 cup fine blanched almond flour
- 2 tbsp powdered erythritol/monk fruit sweetener
- Pinch of salt
- Coffee layer
- 1/2 cup strong espresso or very strong coffee, cooled
- Optional: 1–2 tsp powdered sweetener, to taste
- Mascarpone mousse
- 16 oz mascarpone cheese, cold
- 1 cup heavy whipping cream, cold
- 1/4 cup powdered erythritol/monk fruit sweetener
- 1 tsp alcohol-free vanilla extract or paste
- Pinch of salt
- To finish
- 2 tbsp unsweetened cocoa powder, for dusting
Instructions
- Toast the almond crumb: In a skillet over medium heat, melt the butter. Stir in almond flour, powdered sweetener, and a pinch of salt. Cook, stirring, until golden and nutty, 3–4 minutes. Spread on a plate to cool completely.
- Prep the coffee: Brew espresso and let it cool to room temperature. Sweeten lightly if desired.
- Make the mascarpone base: In a bowl, whisk mascarpone with vanilla and a pinch of salt until smooth (10–15 seconds).
- Whip the cream: In a cold bowl, whip heavy cream with powdered sweetener to soft peaks. Gently fold the whipped cream into the mascarpone until just combined and fluffy. Do not overmix.
- Assemble: Divide 1–2 tbsp almond crumb into 8 small glasses. Drizzle each with 1–2 tsp cooled espresso. Spoon in a layer of mousse. Repeat layers if your glasses are tall.
- Finish & chill: Dust generously with cocoa powder. Chill 1–2 hours to set. Serve cold.

Make-Ahead & Storage
