Dump rock-hard frozen raw peach slices in the casserole dish and 4 other basic pantry items to get a dessert so delicious your friends will be begging.

2. Make the Crumble
In a bowl, mix together the flour, sugar, and cinnamon. Pour in the melted butter and stir until the mixture becomes thick and crumbly.

3. Add the Topping
Sprinkle the crumble mixture evenly over the peaches. It’s fine if the surface looks uneven—those small clumps will bake into crispy, golden bits.

4. Bake
Place the dish on a baking sheet to catch any drips. Bake for 40–50 minutes, until the top is golden brown and the peach juices are bubbling around the edges.

5. Let It Rest
Remove from the oven and let the dessert sit for 15–20 minutes before serving.

Tip: This resting time allows the juices to thicken into a smoother, richer sauce.

Serve warm on its own or with a scoop of ice cream for extra indulgence.
