Preheat your oven to 350°F (because you're about to change lives).
In a bowl, toss apples with maple syrup, espresso powder, cinnamon, nutmeg, vanilla, and lemon juice.
Spread that beautifully spiced mixture into a greased baking dish.
In a separate bowl, mix oats, flour, brown sugar, cinnamon, and salt.
Pour in melted coconut oil and stir until clumps form. You want crumbles, not soup.
Sprinkle the topping evenly over the apples like a fairy with good taste.
Bake for 40 minutes until bubbling and golden.
Cool for 10 minutes unless you're living dangerously.
Serve with vegan ice cream or straight from the pan in a robe.
Store leftovers in the fridge—if there are any.
