I’ve been meaning to post this blackberry crumble recipe on here for ages.  The problem is that as soon as it’s baked and cooled, I eat it.  It’s unavoidable.  So when I found out that this week’s #SundaySupper theme would be recipes on the lighter side, I decided that I would practice self-restraint and not eat it all, so that I could take a picture and contribute this recipe.

I’ll tell you right up front that this recipe contains real butter and sugar.  However, by my usual standards (i.e., a brownie pan 8 inches wide with 3 sticks of butter), this is definitely lighter.  Plus, I use old-fashioned oats, white whole wheat flour, and fresh fruit.  That’s health food in my book.

I make this at least once a week and it disappears within 12 hours.  You can also make it with an equal amount of blueberries, apples, or whatever bakeable fruit you happen to have sitting around.  It’s a toss up whether I like blackberry or blueberry best.   The original Betty Crocker recipe is an apple crumble with all purpose flour, nutmeg, a bit less butter, and a lot more cinnamon.  This is my version after several years of experimentation.

You’ll notice in the photos that I still didn’t get to take a picture of this untouched.  Between me and the rest of the family, we took out a good two-thirds of this crumble before I was able to hide it away for a later photo.  If you needed proof that this is worth trying, there you have it.

On a side note, I absolutely love working with 8 by 8 baking pans.  They work so well for smaller recipes that won’t fill a big old 13 by 9 inch pan.  Here’s the one I use almost every day: the Wilton Perfect Results 8-inch Square Cake Pan.  At just $5, it’s a steal.

  • 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
  • 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.
