Chop apples into ½- to 1-inch (1.3 to 1.5 cm) chunks or slices. Place them into a 1.25 quart (or 1.1 liter) casserole dish. Set aside.
Make the sauce (slurry) by combining the arrowroot powder, ground nutmeg, ground ginger, ½ of the ground cinnamon, cold water, and ½ of the homemade date syrup.
Pour the slurry over the apples in the casserole dish.
Squeeze fresh lemon juice over the apples in the casserole dish.
To make the oat crumble topping, take about ¼ cup of the rolled oats and grind them in a mini bullet blender.
Add the ground rolled oats with the intact rolled oats to the same mixing bowl. Add the chopped walnuts, unsweetened apple sauce, ½ of the cinnamon, and ½ of the Homemade Date Syrup, and salt (optional). Stir well to combine.
Dollup and spread the oat crumble over the apples in the casserole dish.
Bake uncovered at 350°F (175°C) for 30-35 minutes. Remove from oven and let it set for 10 minutes before serving.
