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
Ingredients
4 cups frozen raw peach slices (rock-hard, unthawed)
1 cup granulated sugar
1 cup all-purpose flour
1 teaspoon ground cinnamon
1/2 cup (1 stick) unsalted butter, melted
Directions
Preheat your oven to 350°F (175°C). Place an oven rack in the center position so the topping browns evenly.
Take out a 2-quart oven-safe glass casserole dish (about 8×8 inches or similar). Do not grease it; the butter in the topping will provide enough richness.

Dump the rock-hard frozen raw peach slices directly into the casserole dish and spread them into an even layer. It’s fine if they’re clumped or frosty; do not thaw first.
In a medium mixing bowl, whisk together the granulated sugar, all-purpose flour, and ground cinnamon until no streaks of flour remain and the cinnamon looks evenly distributed.
Pour the melted butter over the sugar-flour-cinnamon mixture. Stir with a spoon or spatula until you have a thick, slightly crumbly batter. It should be moist and clumpy, not pourable like cake batter.
