If you don't want to bake the cinnamon buns the same day, wrap the pan completely in plastic wrap and then foil, and freeze for up to 2 months. Defrost in the refrigerator for a few hours or overnight before baking (be sure to remove the plastic wrap first!). The Crumble can also be used as a blueberry muffin topper or turned into a quick fruit crisp. For the crisp, toss fresh fruit, such as blackberries, with a bit of cornstarch and some brown sugar, then place in ramekins and top with Crumble before baking.
