Using a mixer whip the heavy cream with the vanilla extract and 1 tablespoon of erythritol until stiff peaks form. Set aside.
In a mixer mix together the cream cheese, cocoa powder, erythritol and hazelnut extract until creamy and smooth.
Assemble into two tumbler glasses starting with the crushed hazlenuts, the cream mixture and then the chocolate mixture. Top with the toasted coconut flakes.
Chill in the fridge for 1 hour and then serve.
Notes
Top Tip: use powdered erythritol to avoid the granular texture you will get from regular erythritol. If you don't have powdered, simply blend erythritol in the blender to make it powdered.
