Preheat the oven to 180C/350F. Line a 12-count muffin tin with muffin liners and set aside.
In a small bowl, add your almond flour, salt, and baking powder and mix until combined and set aside. In a separate bowl, combine your melted butter, eggs, sweetener, milk of choice, and vanilla extract, and whisk until glossy. Gently add the dry ingredients until combined. Fold through the chocolate chips at the end.
Evenly distribute the batter amongst the 12 muffin liners. Bake the muffins for 22-25 minutes, or until a skewer comes out mostly clean.
Remove muffins from the oven and let them cool in the tin for 10 minutes, before carefully transferring them to a wire rack to cool completely.
