Vegan Cinnamon Raisin French Toast Casserole

1 In a large bowl, whisk together the casserole ingredients - excluding the loaf of bread. Let the mix sit for 15 minutes.
2 While the mixture is sitting, start to cut the slices of bread into 1 inch pieces - about 9 cubes per slice.
3 After cutting the bread into pieces- start on the streusel mixer. Whisk the melted coconut oil and sugar together. Add in the nuts and stir until they are completely coated. Sprinkle in the whole wheat flour and start stirring. The mixture should resemble damp sand when you've added enough flour - about 3 tbsp.
4 After the 15 minutes is up - add all your bread into a 9x9 baking dish and press down lightly. Pour the wet mixture over the bread slowly - allowing the liquid to be absorbed evenly by all the bread. 
5 Now, preheat your oven to 350 degrees F and allowing the bread to soak. **see above notes about make ahead directions
6 Once the oven is preheated - bake the casserole for 55-65 minutes or until done.
7 Let the casserole cool for 10 minutes before serving. Serve with maple syrup or just as is!
