To make the crust, melt butter and combine it with almond flour, vanilla, xanthan gum and sweetener. Mix well.
Cover your form (standard size, 9-Inch Springform Pan will do) with parchment paper or use silicone cake form and distribute crust mix on the bottom of your form. Poke it with a fork.
Bake 10-15 min in a preheated 300F oven then remove and set aside.
MAKING THE FILLING
For the filling: In a bowl combine softened cream cheese, sour cream, sweetener, vanilla and lemon juice. Mix it well with a mixer.
Add eggs one at a time and blend till fully incorporated.
Add lemon zest and xanthan gum, mix well.
Pour the filling on top of the crust.
BAKING
Put it in a preheated 300F oven. Bake it till edges are set, the middle might be a bit jiggly (around 30 minutes).
Take it out and let it cool then refrigerate for at least 4 hours. It’s better to keep it in a fridge overnight to let it fully set. Decorate to your liking.
