Ingredients for Your Parfait (Serves 4)
Here’s what you’ll need to create this layered masterpiece.
For the Silky Chocolate Mousse
- ½ cup heavy whipping cream
- 2 tbsp unsweetened cocoa powder
- 1½ tbsp powdered erythritol or monk fruit sweetener
- ¼ tsp vanilla extract
- A tiny pinch of salt
For the Creamy Vanilla Layer
- ½ cup full-fat cream cheese, softened to room temperature
- ¼ cup heavy cream
- 1 tbsp powdered erythritol
- ¼ tsp vanilla extract
For the Rich Keto Caramel Sauce
- ¼ cup unsalted butter
- 2 tbsp powdered allulose (preferred for smoothness) or erythritol
- 2 tbsp heavy cream
- ¼ tsp xanthan gum (optional, for a thicker sauce)
- A pinch of sea salt
For Assembly & Topping
- ¼ cup salted roasted peanuts, chopped
- 2 tbsp sugar-free chocolate chips
- 1 tbsp coconut oil (for the chocolate drizzle)

Essential Kitchen Tools
- Hand mixer or stand mixer
- Several mixing bowls
- Small saucepan
- 4 small jars or parfait glasses
- Silicone spatula
- Microwave-safe bowl
- Measuring spoons and cups
Step-by-Step Instructions
Step 1: Create the Chocolate Mousse Layer
- In a chilled medium bowl, whip the heavy cream with a hand mixer until soft peaks begin to form.
- Gently sift in the cocoa powder, sweetener, vanilla, and salt.
- Continue whipping until the mixture is thick, fully combined, and holds stiff peaks.
- Place the mousse in the fridge to chill and set for at least 10–15 minutes.
Step 2: Prepare the Vanilla Cream Layer
- In a separate bowl, beat the softened cream cheese until it’s completely smooth and free of lumps.
- Gradually pour in the heavy cream while whipping until the mixture becomes light and creamy.
- Beat in the powdered sweetener and vanilla extract until fluffy and incorporated.
- Refrigerate this layer while you make the caramel.
Step 3: Make the Keto Caramel Sauce
- Melt the butter in a small saucepan over medium heat.
- Whisk in the powdered allulose and cook for 1-2 minutes, stirring constantly to prevent burning.
- Pour in the heavy cream and a pinch of sea salt, stirring until the mixture bubbles and combines smoothly.
- If using, sprinkle in the xanthan gum to help thicken the sauce.
- Remove from heat and allow it to cool; the sauce will thicken further as its temperature drops.
Step 4: Assemble Your Parfaits
- Begin by spooning about 2 tbsp of the chocolate mousse into the bottom of each parfait glass.
- Carefully add a 2 tbsp layer of the vanilla cream on top.
- Drizzle with about 1 tbsp of the cooled caramel sauce.
- Sprinkle 1 tbsp of chopped roasted peanuts over the caramel.
- Repeat the layers one more time: chocolate mousse, vanilla cream, caramel, and peanuts.
- For the final touch, melt the sugar-free chocolate chips with coconut oil and drizzle generously over the top.
Tips for Parfait Perfection
Presentation & Serving
Showcase the beautiful layers by serving your parfaits in clear glasses or mason jars. For a gourmet touch, garnish with a few extra chopped peanuts or a sprinkle of flaky sea salt. This dessert is best served chilled to enhance its rich taste and firm texture.
Storage Solutions
- In the Fridge: Cover and refrigerate assembled parfaits for up to 5 days. They are perfect for making ahead!
- In the Freezer: While the individual components can be frozen, assembled parfaits may become watery upon thawing. It’s best to assemble just before serving if you’ve frozen the layers.
Ingredient Swaps & Variations
- Dairy-Free: Use full-fat coconut cream in place of heavy cream and a dairy-free cream cheese alternative.
- Nut-Free: For a nut-free version, simply omit the peanuts or substitute them with toasted sunflower or pumpkin seeds for a similar crunch.
- Different Sweeteners: Monk fruit, stevia, or other erythritol-based sweeteners work well. For the caramel, allulose is highly recommended as it resists crystallization and creates a much smoother sauce.

How to Lower the WW SmartPoints
If you’re following WW, you can easily lighten this dessert with a few smart swaps:
- Use fat-free Greek yogurt instead of heavy cream in the vanilla layer.
- Opt for low-fat cream cheese instead of full-fat.
- Reduce the amount of peanuts or use slivered almonds, which are lower in fat.
- Use the caramel sauce and chocolate drizzle more sparingly.
These adjustments can help bring the total down to 4–5 SmartPoints per serving.
