If you’re concerned about getting sticky leftovers out of the crockpot, try spraying the slow cooker with baking spray before adding ingredients. As for the oven method, you could bake the Crockpot Cherry Dump Cake at 350°F for 30-45 minutes. BUT only if your slow cooker has an oven-safe removable insert (check your manual). Otherwise, my traditional oven-baked Cherry Dump Cake recipe might be a better fit.
