What to do with leftover crumb topping? After making an apple crostata, I was left with a lot of leftover crumb topping. The topping is delicious and I could eat it by itself ;) But since it includes raw flour, I'd rather find a more sophisticated and easy on my stomach solution. Do any of you have any creative ideas that involve using crumb topping without baking another pastry? :)

The ingredients of my topping are:


3/4 cup all-purpose flour
1/4 cup packed dark-brown sugar
1/4 cup granulated sugar
1/2 teaspoon coarse salt
1/2 teaspoon cinnamon
1/4 teaspoon allspice
1 stick cold unsalted butter


I probably have 1/3 left.
If you really don't want to bake anything else, you could bake the crumb on it's own. I'd be sure to put it on parchment or a silpat to avoid it sticking to the surface below. Bake it at 350F or so until it's browned. Once it's baked, it should last a while as long as it's stored in an airtight container. It would probably be good as an ice cream topping?
