Preheat oven to 350 degrees F.
Line 18 muffin cups with liners and spray the inside of the liners with avocado oil spray or non-stick spray of choice.
Whisk together 2 cups oat flour (reserving 2 tbsp for later), almond flour, salt and baking soda in a large bowl.
In a second large bowl, mix together the eggs, honey, vanilla extract, milk, oil, and apple cider vinegar until well combined.
Add the dry ingredients to the wet ingredients and stir until just combined.
Gently fold peaches into the batter.
Divide batter evenly between 18 muffin cups, filling 3/4 of the way full.
Bake for 18-20 minutes or until toothpick inserted comes out clean.
Remove muffins from oven and allow to cool for 10 minutes, then place on wire rack to finish cooling.
