Combine almond flour, coconut flour, erythritol, and baking powder in a bowl and mix well.
Add eggs and soy milk to the mixture to make the dough.
Mix the filling ingredients (walnuts, pecans, erythritol, cinnamon powder) together.
Take a portion of the dough, flatten it in your palm, add the filling, and shape into a ball.
Heat coconut oil in a pan, add the dough balls, and cook until golden brown on both sides.
