Preheat oven to 350 degrees F.
In a stand mixer on a medium low speed cream the eggs, sugar, vanilla, and non dairy milk.
Add the applesauce, coconut oil, cinnamon, and nutmeg. Beat for 2 minutes. Turn the mixer off and add the GF All Purpose Flour.
Turn the mixer back on to slow and add the baking powder, baking soda, salt, and xanthan gum.
Turn speed to medium and beat for 5 minutes, scrapping down the sides of the bowl half way through.
Grease your 9X13 baking pan and pour the batter in and spread it evenly.
Spread your crumb topping over the top.
Bake for about 45 minutes. Check with a toothpick and when it comes out clean it is done.
