Step 1

Preheat oven to 350 degrees.

Step 3

Spray a 9 x 9-inch baking pan with non-stick spray. Set aside.

Step 5

Add raspberries to a large bowl followed by sugar and cornstarch. Toss to combine, then add berries to the baking dish and distribute the sugar/cornstarch mixture that's left in the bowl over the fruit.

Step 7

Make the topping by mixing the flour and brown sugar together in a medium bowl. Cut in the flour using a pastry blender, two knives or your fingers, until the butter is well distributed. Then pinch and squeeze the topping mixture with your fingers to make nice crumbs.

Step 9

Sprinkle the crumbs over the berries.

Step 11

Bake for 35-45 minutes or longer, until the middle of the crisp is bubbling.

Step 13

Serve warm with a scoop of vanilla ice cream or sweetened whipped cream.
