About This Recipe

These no-bake keto tiramisu mousse cups are pure coffee-kissed indulgence: fluffy mascarpone cream layered with buttery almond “ladyfinger” crumbs and a dusting of cocoa. They’re alcohol-free, low in carbs, and perfect for make-ahead desserts or special occasions. Makes 8 servings; prep in 20 minutes plus 1–2 hours to chill.

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

1. 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.
2. Prep the coffee: Brew espresso and let it cool to room temperature. Sweeten lightly if desired.
3. Make the mascarpone base: In a bowl, whisk mascarpone with vanilla and a pinch of salt until smooth (10–15 seconds).
4. 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.
5. 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.
6. Finish & chill: Dust generously with cocoa powder. Chill 1–2 hours to set. Serve cold.

Tips & Variations

• Mocha twist: Whisk 1 tbsp unsweetened cocoa into the espresso or the mousse.
• Nut-free option: Use finely ground sunflower seed flour for the crumb (taste and add a few drops of vanilla to counter any bitterness).
• Flavor accents: Add 1/4–1/2 tsp rum extract or coffee extract (alcohol-free) to the mousse for classic tiramisu vibes.
• Sweetness level: Start with the listed amounts and adjust to taste—sweetness can vary by brand.
• Presentation: Garnish with shaved 85–90% dark chocolate or a few fresh raspberries.

Make-Ahead & Storage

• Refrigerate, covered, for 3–4 days. The crumb softens slightly (delicious!).
• Not freezer-friendly: the mousse texture can become grainy once thawed.
• Assemble in lidded jars for easy meal prep and portion control.
