Prepare my coconut flour bread the day before you plan to make this bread pudding. You'll have 14 slices of bread but only need 8 slices for this recipe. Once baked and cooled, slice bread into 1 inch cubes and lay on a baking sheet to dry overnight on the counter. If you don't have time for this step, you can toast the cubes in a 350 degree oven for 5-10 minutes to dry the bread out.
Grease a 9 by 13 baking dish. Preheat oven to 350 degrees F. Pour the dried cubed bread into the greased dish.
In a bowl stir together the remaining ingredients and pour over the cubed bread.
If adding in optional toppings, sprinkle those all over the bread. If not using optional toppings skip this step.
Mix together the melted butter and allulose sweetener or choice sweetener and pour all over the bread.
Bake for 40-45 minutes or until center is set and bread is browned.
