Preheat the oven to 350F / 180C. Line an 8X8 baking glass pan with parchment paper and set aside.
In a large bowl, using an electric mixer or a food processor, combine the crust ingredients: almond flour, melted butter, erythritol, vanilla extract, and salt.
Firmly press the thick dough into the prepared pan, making sure the crust is evenly distributed. Bake for about 15-20 minutes or until the edges are lightly golden brown.
