Place dates into a blender. Cover with hot water and allow to sit for 5 minutes. Drain water and place dates back in blender. Add salt, coconut milk, maple syrup, and vanilla extract. Blend until smooth. Set aside.
Heat 2 tablespoons vegan butter over low heat in a 10-inch oven-prooof skillet. Add apples and salt. Cook for 3-4 minutes over medium heat, stirring occasionally. Add lemon juice, cinnamon, arrowroot starch, coconut sugar, and vanilla extract. Stir to combine. Take off heat.
Pour about 1 cup of the date caramel over the apples. Stir to evenly incorporate.
Preheat oven to 350 degrees Fahrenheit.
In a medium bowl combine oats, cinnamon, coconut sugar, pecans, and salt. Stir to evenly incorporate ingredients.
Add small pieces of solid vegan butter or coconut oil to oat mixture. Using your hands, incorporate the vegan butter so that it has moistened the oat mixture. Sprinkle oat mixture evenly on top of apples.
Bake for 35-45 minutes until apples are bubbling and the oat mixture on top has become golden. Watch to make sure your pecans do not burn. Serve warm with ice cream.
Store leftovers in the refrigerator and reheat in microwave to serve again.
