Preheat oven to 350 degrees F and line 12 muffin cups with liners. Spray the inside of the liners with avocado oil spray or non-stick spray of choice and set aside.
Whisk together oat flour, almond flour, salt and baking soda in a large bowl.
In a second large bowl, mix together the eggs, honey/maple syrup, 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 1 ¼ cup of the trail mix ingredients into the batter, reserving the rest for topping.
Divide batter evenly between 12 muffin cups, filling almost to the top.
Top each muffin cup with the remaining ¼ cup of trail mix and bake for 18-20 minutes or until a toothpick inserted comes out clean.
Remove the muffins from the oven and allow to cool for 10 minutes, then place on wire rack to finish cooling.
Enjoy!
