Shabby in the City has graciously invited us to her blogger potluck, and as usual, I am a little late to the party. But I'm here, and this is the recipe I have made for you all. It is a great recipe, because you can make the crumble topping ahead of time and keep it in the freezer. This crumble topping recipe actually makes 6 cups of crumble (enough to make the blueberry peach crumbles recipe 3 times!) You can also use the crumble topping as a topping for fruit pies.
