There’s nothing quite like biting into a cold, crisp, sweet apple. Except maybe for a crunchy steaming hot apple crumble with creamy frozen vanilla ice cream on top.
In a small bowl, mix the oat flour, almond flour, brown sugar, and a pinch of salt. Add the melted butter and mix until the mixture resembles sand.
Squeeze half a lemon into a 9x13 baking dish. Core and slice the apples into wedges and add them to the baking dish as well as the cinnamon and ginger. Stir everything together.
Top the apples evenly with the sugar/flour crumb mixture and place the baking dish, uncovered, into the preheated oven. Bake for 50 to 60 mins or until the top is brown and crunchy.
