Preheat the oven to 350° F.
In a medium sized bowl, mix together the almond flour, baking soda and apple pie spice. Set aside.
In a large bowl, add the eggs, coconut oil, and stevia and erythritol blend (or maple syrup) and whisk well.
Add the dry mix to the wet mix and gently stir together. Over-mixing will result in tough muffins.
Add the grated apples and gently fold into your mixture.
Line muffin tins with silicone or paper liners and fill tins 3/4 full of batter.
Bake for 20 to 25 minutes, or until the top is golden brown and a toothpick inserted in the center comes out clean.
Let the muffins cool in the pan for 10 minutes and finish cooling on a wire rack.
