I love the tastes of fall SO much! Pumpkin spice is my favorite, but apples and cinnamon come in at a close second. I love making Apple Cranberry Pecan Crumble, but sometimes just apples is nice. And for this Apple Cinnamon Crumble recipe, I swapped the pecans with walnuts. This recipe is seriously so easy…just dump it all in a pie plate and cook!
