This gluten free no bake peanut butter cheesecake is rich, creamy, and perfect for any occasion. It's a crowd-pleasing dessert that's absolutely worth every bite.
Mix the crushed gluten free chocolate sandwich cookies with the melted butter until all the crumbs are evenly moistened. Press firmly and evenly into the bottom of a 9-inch springform pan. Freeze for 15 minutes while you prepare the filling.
In a large bowl, beat the cream cheese and peanut butter together on medium speed until very smooth and creamy, about 3 minutes. Add the powdered sugar and vanilla extract, and beat until fluffy and well combined.
In a separate chilled bowl, whip the 1 1/2 cups heavy cream until stiff peaks form.
Fold the whipped cream into the peanut butter mixture in two additions, gently folding with a spatula from the bottom up until no white streaks remain. The filling should be light and mousse-like.
Spoon the filling over the chilled crust and spread it into an even layer, smoothing the top. Refrigerate for at least 6 hours or overnight until fully set.
For the chocolate ganache topping, heat the 1/3 cup heavy cream in a small saucepan until it just begins to simmer. Pour it over the chopped semi-sweet chocolate, let sit for 1 minute, then stir until smooth and glossy. Let it cool for 5 minutes.
Pour the ganache over the set cheesecake and gently tilt the pan to spread it evenly. Sprinkle with the chopped roasted peanuts and a pinch of flaky sea salt.Return to the refrigerator for 20 minutes to let the ganache set before releasing the springform ring and slicing.
