Step 1

Preheat oven to 375°F. Grease an 9-inch square baking dish or 8-inch x 11-inch baking dish.

Step 2

Place the peaches into the greased baking dish; add the sugar, cornstarch, lemon juice and cinnamon on top, stir and set aside.

Step 3

In a small bowl, combine the oats, flour, brown sugar and salt. Cut in butter using a fork or your hands until mixture resembles coarse crumbs. Sprinkle the streusel mixture over the peach mixture.

Step 4

Bake until the crisp topping is golden brown and the filling is bubbly, about 35-40 minutes. Allow to cool for a few minutes. Serve warm with a scoop of ice cream, if desired.
