What's the secret to a great crumb pie? An easy crumb topping of course! It's so quick to make, using butter, light brown and graulated sugar, flour, and a touch of cinnamon. We suggest you prep it now and keep some in your freezer so you can enjoy wonderful pies all summer and fall, think peach crumb pie, blueberry crumb pie, apple crumb pie. Or toast the topping on a baking sheet in a 350-degree oven for 15 minutes, and sprinkle over ice cream, frozen yogurt, or fresh fruit.
