Place rack in center of oven and preheat oven to 350°.
Note: this batter may be mixed by hand, with a hand blender, or in a standing mixer
Grease a 9"x13" baking pan (I use the Pyrex pan) with butter or oil.
Melt butter on low heat, if using. While the butter is melting assemble the rest of the ingredients.
Beat eggs in a large bowl. Add all the other ingredients. Add the melted butter or oil. Stir to combine with a large spatula or on medium speed with a mixer. Taste batter for sweetness and add a little more xylitol if desired.
Put batter in greased baking pan and put in oven. Bake for 25-30 minutes or until center of cake feels somewhat firm when touched with your finger, and a toothpick inserted in the center comes out almost clean. Do not over bake. A tiny bit under baked is better than over baked.
Allow to cool a little (may be served warm) and serve with whipped cream (or coconut whipped cream) and unsweetened apple sauce.
