  • 12 ounces blackberries fresh or frozen, about 3 cups
  • 6 tablespoons unsalted butter softened
  • 2/3 cup brown sugar
  • 1/2 cup old fashioned oats
  • 1/2 cup white whole wheat flour or all-purpose flour
  • 1/4 teaspoon cinnamon
  • 1 pinch sea salt


  1. Preheat the oven to 375. Prepare an 8 inch square or 9 inch round pan by lining it with foil. Place the berries in the lined pan.
  2. Place the butter, sugar, oats, flour, cinnamon, and salt in a medium sized bowl. Stir vigorously until the ingredients have formed into small clumps. At this point, there should be no loose flour or sugar in the bowl and no visible bits of butter.
  3. Using the back of the fork, compact the mixture firmly into the bowl until it sticks together in one large clump. Then, use the tines of the fork to gently break it into clumps of various sizes- some large, some small. Carefully tip the bowl sideways over the pan of berries and use the fork to scoot the clumps out of the bowl evenly over the top of the berries.
  4. Place the pan in the oven and bake for 30 minutes, or until the top is golden brown. Let cool until just slightly warm so that the topping can firm up properly. Enjoy!

Recipe Notes

You may use an equivalent amount of any bakeable fruit, such as raspberries, blueberries, or apples.

To make a larger blackberry crumble that serves 10-12, double the quantities of all the ingredients and bake in a 2 quart casserole dish or a 13 by 9 baking pan.
