Slice 4-5 Granny Smith Apples, set aside. We used this apple slicer.
Melt one stick of butter in pan on stovetop, then add in the apples.
Add sweetener, vanilla, cinnamon, and stir. Allow apples to soften and mixture to thicken, about 5-7 minutes. Sweetener and butter will thicken to a deeper brown.
Pour mixture into your baking dish, set aside.
Preheat oven to 350 degrees.
Melt one stick of butter, set aside.
In a separate bowl combine almond flour, sweetener, xanthan gum, and salt.
Add melted butter to the dry mixture. This should form small moist clumps.
Top the apples with crisp topping, spreading it out to make sure surface of apples is completely covered with the crisp mixture.
Bake for 20-25 minutes until the topping is slightly browned and slightly bubbling.
