Preheat to 350F degrees. Spray a 9x13 inch baking dish with non-stick cooking spray.
Place sliced apples into baking dish. Mix sugar, flour, ground cinnamon, and ground nutmeg together, and sprinkle over apples.
In a medium bowl, combine oats, flour, brown sugar, baking powder, baking soda, chopped pecans and melted butter. Crumble evenly over the apple mixture.
Bake for about 45 minutes. Serve warm with vanilla ice cream!
Notes
My personal favorite will forever be granny smith apples (hence why it’s used in this recipe!). But if you’ve got a drawer of apples to use up and want to put off buying even more apples… honey-crisp and golden delicious apples are also some great options.
The secret to the best apples for apple crisp is that they are crisp, tart, and stand up well to baking like these options I’ve listed. For more complex flavors, try mixing different kinds of apples!
