Equipment

  • 9-inch tart pan
  • Medium Bowl
  • Blender
  • Fine Mesh Sieve
  • Medium Saucepan
  • Chilled bowl

Ingredients
  

No-Bake Crust

  • 1 cup almond flour
  • 1/4 cup cocoa powder
  • 1/4 cup powdered keto sweetener (for crust)
  • 1/4 cup melted butter

Raspberry Mousse

  • 2 cups fresh raspberries (or thawed frozen, for puree)
  • 2 tbsp fresh lemon juice
  • 2 tsp grassfed gelatin
  • 1 1/4 cups chilled heavy whipping cream
  • 2/3 cup powdered keto sweetener (for mousse)
  • 1/2 cup fresh raspberries (for garnish, optional)

Instructions
 

  • For the Simple No-Bake Crust:
  • 1. Lightly grease a 9-inch tart pan to ensure easy removal later.
  • 2. In a medium bowl, whisk together the almond flour, cocoa powder, and powdered keto sweetener until well combined and lump-free.
  • 3. Stir in the melted butter until the mixture clumps together, resembling moist crumbs.
  • 4. Press this mixture firmly and evenly into the bottom and up the sides of your prepared pan. Pop it into the fridge to chill while you prepare the filling.
  • For the Creamy Raspberry Mousse:
  • 1. Puree the raspberries in a blender until very smooth, then pass the puree through a fine-mesh sieve into a bowl to remove all seeds, leaving you with a silky, vibrant liquid.
  • 2. Transfer this strained raspberry puree to a medium saucepan and stir in the fresh lemon juice.
  • 3. Sprinkle the gelatin evenly over the surface of the puree and let it sit for about 5 minutes to soften.
  • 4. Place the saucepan over medium-low heat and whisk gently until the gelatin is completely dissolved and the mixture is smooth. Remove from heat and allow it to cool down completely.
  • 5. In a separate, chilled bowl, whip the heavy cream with the powdered keto sweetener until it forms beautiful, stiff peaks.
  • 6. Set aside about 1/2 cup of the whipped cream for decorating your tart later.
  • 7. Gently fold the cooled raspberry puree into the remaining whipped cream. Mix carefully until there are no streaks and you have a lovely, uniform pink mousse. This gentle folding keeps the mousse light and airy!
  • 8. Pour the prepared mousse into your chilled tart crust and return it to the refrigerator. Let it chill for at least 3 hours, or until it's perfectly set and firm enough to slice.
  • To Garnish (Optional):
  • 1. Once your tart is set, pipe or spread the reserved whipped cream decoratively around the edges or over the center.
  • 2. Top with extra fresh raspberries for a beautiful finish and a burst of fresh flavor. Enjoy your stunning, healthy, and easy-to-make dessert!
