Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a large mixing bowl, combine almond flour, coconut flour, baking powder, salt, and erythritol. Mix well.
In a separate bowl, blend cream cheese and melted butter until smooth. Add the eggs and mix until fully incorporated.
Gradually add the dry ingredients to the wet mixture, stirring until a dough forms. Knead the dough gently until it is smooth.
Roll the dough out between two sheets of parchment paper into a large triangle shape, about 1/4 inch thick.
Cut the dough into smaller triangles and roll each one from the base to the tip to form croissants.
Place the croissants on the prepared baking sheet and bake for 20-25 minutes or until golden brown.
Let them cool slightly before serving. Enjoy your Keto Croissants with your favorite fillings!
