Keto no-bake pumpkin and chocolate mousse cake recipe

Torta mousse alla zucca e cioccolato keto: ricetta senza cottura

If you're looking for an autumn dessert that combines creaminess, flavor, and lightness, this low-carb Pumpkin and Chocolate Mousse Cake is the recipe for you. It's no-bake (except for the initial pumpkin cooking), flour-free, gluten-free, sugar-free, and completely low-carb. It's also perfect for those following a ketogenic diet.

The naturally sweet flavor of pumpkin pairs perfectly with the intensity of dark chocolate, creating a firm yet velvety mousse with a deep, balanced taste. A true dense and creamy indulgence, ideal as an after-dinner dessert or an energetic snack, without cheating!

🥄 Ingredients (for 2 servings)

  • 150 g baked pumpkin (very dry, such as Delica or Mantovana variety)
  • 50 g 90% dark chocolate (or 85%, preferably without added sugar)
  • 40 g light mascarpone or full-fat Greek yogurt
  • 12–15 g melted butter (or ghee for a more delicate flavor)
  • 20 g erythritol or stevia (adjust to desired sweetness)
  • Cinnamon or vanilla to taste for flavoring
  • A pinch of fine salt (enhances the chocolate flavor)

🍳 Method

  1. Bake the pumpkin
    Cut the pumpkin into 2–3 cm cubes and arrange them on a baking sheet lined with parchment paper. Bake in a static oven at 180 °C for about 25–30 minutes, until the flesh is tender and slightly golden. Let it cool completely. For a perfect result, leave the cubes in the turned-off oven with the door ajar for another 5–10 minutes: they should be dry, not moist.
  2. Prepare the mousse base
    Blend the cooked pumpkin with the mascarpone (or Greek yogurt) until you get a smooth, homogeneous, and velvety cream.
  3. Melt the chocolate
    In a small saucepan or microwave, melt the dark chocolate with the butter or ghee. If using the microwave, stir every 20–30 seconds to prevent burning. Let it cool slightly for 2 minutes.
  4. Combine the ingredients
    Pour the melted chocolate into the pumpkin cream, add the erythritol, a pinch of salt, and the chosen spices. Mix vigorously until you get a uniform, thick, and fragrant mixture.
  5. Chill in the fridge
    Pour the low-carb mousse into a small mold lined with plastic wrap or into two single-serving bowls. Smooth the surface well with a spatula. Cover the low-carb mousse with plastic wrap and refrigerate for at least 4 hours, preferably overnight.

🍫 Why it's perfect for a low-carb diet

This low-carb mousse cake is a true ally for those following a low-carb or ketogenic diet. Let's see why:

  • Low in sugar: uses only naturally occurring sugars in the ingredients, without flours or high-glycemic sweeteners.
  • Good fats: butter (or ghee) and mascarpone provide healthy fats, ideal for maintaining stable blood sugar and prolonging satiety.
  • Rich in fiber and micronutrients: pumpkin is a source of beta-carotene, potassium, and fiber, but with a carbohydrate content that is manageable when used in moderate portions.
  • 90% dark chocolate: perfect for ketogenic, provides antioxidants and a deep flavor, without sugar.
  • Gluten-free and grain-free: therefore also ideal for those with intolerances or following anti-inflammatory protocols.
