Wash your hands thoroughly with soap and warm water.
In a microwaveable ramekin or large mug, place chopped apple, pecans/walnuts, maple syrup, melted coconut oil, optional chia seeds, cinnamon, salt, and ginger. Stir to combine and thoroughly coat the apple in oil and syrup. Microwave on high for 30 seconds. This will begin to soften the apples slightly and release their juices.
Make the crumb topping. In a small mixing bowl, stir together coconut sugar, flour, oats, cinnamon, and nutmeg until well combined. Add coconut oil and use a fork to cut the oil into the dry ingredients creating smaller pieces. The mixture will clump together into large crumbs.
Layer the crumb topping evenly over the apple mixture by placing small pieces sporadically over the apples until the apples are mostly covered. Place in the microwave on high for about 1 - 2 minutes. Cooking time will vary based on microwave, climate, and moisture content of apples. Remove dish carefully using a hot pad as the dish will be very hot.
Allow to cool about 3-5 minutes before serving. Add a dollop of dairy free whipped cream, ice cream, or yogurt. Enjoy!
Make multiple servings all at once for an easy breakfast, snack or dessert all week long. Leftovers should cool completely before storing in an airtight container in the refrigerator for up to 2-3 days.
