Preheat oven to 400 degrees and add liners to muffin pan.
In a medium bowl whisk together flours, sugars, baking powder, cinnamon, apple pie spice, xanthan and salt. Set aside.
In small bowl add egg replacer and warm water. Stir and let sit for one minute to thicken.
In stand mixer bowl (paddle or whisk attachment is ok), mix oil, egg replacer, and milk. Mix until combined for 1-2 minutes. It will look a little frothy.
Remove bowl from stand mixer and add dry mix, shredded apples and water. Use a spatula to mix this into a batter.
Divide and fill each muffin cup evenly.
In small bowl mix up the topping ingredients and sprinkle it on top of each muffin before baking.
Bake muffins for 15-20 minutes. Mine took about 17 minutes.
Let them cool. Serve and enjoy!
