Dark Cherry Cranberry Crisp with Oat Crumble Topping

A comforting fruit crisp combining sweet-tart dark cherries with tangy cranberries under a golden oat crumble. The filling is thickened on the stovetop with cornstarch and enhanced with warm cinnamon and optional dark rum for depth. Perfect for fall gatherings or winter desserts when you want something homey yet special. The contrast between the jammy fruit filling and crispy oat topping makes this version particularly satisfying.

Microwave butter for 30 seconds until mostly melted with a chunk remaining for easier mixing into the crumble topping.
Stir the filling constantly while cooking to prevent cornstarch from clumping and ensure even thickening.
Look for cranberries that pop and filling that bubbles at edges to confirm proper doneness.

FAQ
Can I use fresh cranberries instead of frozen?
Yes, fresh cranberries work perfectly. They may take slightly longer to pop and soften during the stovetop cooking process.
What if I don't have dark rum?
Lemon juice works as a substitute and adds bright acidity. You could also use vanilla extract or omit entirely.
How long will this keep?
Store covered in refrigerator for up to 3 days. Reheat portions in the oven to restore the crispy topping texture.
