Preheat oven to 350 degrees
Peel, seed and cut apples into 1 inch cubes
Once all the apples are peeled and chopped place in a bowl and add the lemon juice, maple syrup, cinnamon, and tapioca starch and toss until the apples are well coated
Spread the apples out in a 9 x 13 baking dish and place in the oven. Bake for 30 minutes
While the apples are baking, combine all the crumble ingredients in a bowl and mix until incorporated
Once the apples have baked for 30 minutes, remove the baking dish from the oven and spread the crumble mixture out evenly on top. The crumble mixture is pretty gooey so you will end up with some clumps on top of the apples
Place the baking dish back into the oven and bake for another 15-20 minutes or until the crumble turns golden brown and the apples are bubbling
Remove from the oven and allow to cool. When the apple crisp is done baking, you may noticed that it has risen in the oven. This is from the juices and apples bubbling and it will shrink once taken out of the oven.
My favorite way to enjoy this apple crisp is served warm with vanilla bean ice cream. Enjoy!
