  • ¾ cups (90 g) all purpose flour
  • ¾ cups (99 g) old fashioned oats
  • ½ cup (107 g) packed light brown sugar
  • ¼ cup (50 g) granulated sugar
  • ½ teaspoon ground cinnamon
  • ½ teaspoon table salt

  • Preheat and prepare the pans. Adjust oven rack to middle position and heat oven to 450oF. Spray a 9x9 baking dish.
  • Make the filling. Toss berries, sugar and cinnamon, and flour in a large mixing bowl and pour into baking dish.
  • Make topping. In the same mixing bowl, combine flour, oats, sugar, cinnamon, brown sugar, and salt in bowl. Stir in butter until mixture is thoroughly moistened and crumbly. Sprinkle over the berry mixture.

  • I always recommend being careful measuring your flour. For best results I always recommend using a kitchen scale
  • Using cornstarch is key so your fruit crisp doesn't end up runny. You can also use flour if you don't have any on hand. 
  • You want to use a combination of 6 cups of berries- the assortment is up to you. But I like using 2 cups strawberries, 2 cups blueberries, 1 cup raspberries and 1 cup blackberries. Raspberries and blackberries have a lot of seeds so I tend to use less of those. If you are frozen berries I do not thaw them but simply stir them in. The crisp may require a few minutes extra of baking time.
