Preheat oven to 375 degrees.

Peel and core your apples and stir in large bowl with lemon juice and maple syrup. Sprinkle with tapioca starch and stir together. Using coconut oil, oil a 9x11 glass baking dish. Pour prepared filling into baking dish.

Prep the topping by either chopping the almonds and walnuts or by separately placing them in your blender or food processor and pulsing until the size you desire. Stir in coconut sugar, cinnamon, nutmeg and salt.

In small saucepan, slowly heat maple syrup, butter and vanilla extract. Once melted, stir into bowl of topping. Drop scoops of topping onto the filling and bake for 45-50 minutes, placing foil on top to prevent burning for last 10 minutes.
