This zero-calorie sweetener is ideal for those looking to reduce sugar intake while still enjoying sweetness. It mimics sugar’s taste without the carbs, making it a staple in keto baking.

Vanilla Extract (1 teaspoon):
This aromatic addition enhances the overall flavor profile of the mousse, balancing the rich chocolate and nutty notes with a hint of sweetness.
Salt (1/4 teaspoon):
A pinch of salt elevates the flavors, making the sweetness more pronounced and the chocolate taste even richer.
Eggs (4 large):
Eggs are crucial for adding structure and creaminess to the mousse, ensuring a light and airy texture that melts in your mouth. This ingredient also brings added protein to the dessert.

Cooking Tips and Notes
When preparing your Hazelnut Mousse Cake (Keto-Friendly), a few tips can elevate your baking experience and ensure a delicious outcome.
Toasting Hazelnuts
Toasting your hazelnuts is a crucial step. It enhances their flavor, adding depth and richness to the mousse. Simply spread them on a baking sheet and toast in a preheated oven at 350°F (175°C) for about 10 minutes, keeping an eye on them to prevent burning.
Whipping Heavy Cream
Achieving the perfect whipped cream is essential for the mousse’s texture. Whip the heavy cream until soft peaks form, being careful not to overwhip, as this can lead to a grainy texture. Soft peaks will ensure a light and airy mousse that melts in your mouth.
Chilling Time
Patience is key! Allow the mousse to chill in the refrigerator for at least 4 hours. This step is not only important for setting the mousse but also for allowing the flavors to meld beautifully. Planning ahead will ensure that your dessert is perfectly set and ready to impress your guests.
By following these tips, you can create a Hazelnut Mousse Cake that is not only keto-friendly but also bursting with flavor and texture. Happy baking!
