6 cups fresh or frozen blackberries

3/4 cup plus 1 tablespoon all-purpose flour

1/2 cup granulated sugar

1/2 teaspoon ground cinnamon

1 lemon, juiced 

1/2 cup quick-cooking oats 

1/3 cup chunky peanut butter 

1/4 cup packed light brown sugar 

6 tablespoons unsalted butter, melted 

1/8 teaspoon kosher salt 


  1. Preheat the oven to 400 degrees F and place a rack in the center of the oven.
  2. Place the berries in a 12-inch high-sided skillet or braiser set over medium heat. Stir in 1 tablespoon of the flour, 1/4 cup of the sugar, 1/4 teaspoon of the cinnamon and the lemon juice. Cook until all the juices release, 5 minutes.
  3. To make the crumble topping, in a medium bowl combine the oats, peanut butter, brown sugar, the remaining 1/4 cup granulated sugar and the remaining 3/4 cup flour. Mix with a spoon until combined. Pour the butter into the dry crumble mixture and stir to achieve a crumble consistency. Spoon dollops of the crumble mixture over the berry mixture. Bake until the topping is crisp, 20 minutes. Cool the crumble for 5 minutes, then serve.
