This versatile crumb topping is great on our Berry-Buttermilk Crumb Muffins, or any baked good that needs a topping of big, crunchy crumbs. You can make this ahead of time in a large batch, so it's always ready when you need it. It keeps for 1 week in the fridge and can be frozen up to 3 months. Bring it to room temperature before using.
