Strawberry crumb bars on a white cutting board

Whole Grain Crumb Bars

To highlight the nutty flavor of the oat bran and wheat flour, I added some finely chopped almonds on top of the fruit layer. This is optional, but offers additional texture and it aaaaaalmost tastes like a PB&J sandwich.

What You'll Need

For the dough:

  • 1 cup all-purpose flour
  • 1 cup whole wheat flour
  • 1 cup butter softened
  • cup brown sugar
  • ½ cup oat bran
  • 1 egg
  • ¼ tsp salt

For the filling:

  • 4 cups mixed berries or stone fruit diced if needed
  • cup granulated sugar
  • 2 tablespoons cornstarch
  • Juice of 1 lemon

Optional:

  • ¼ cup almonds chopped

What to Do

Prepare the fruit and the oven:

  1. Preheat the oven to 350ºF.
  2. In a large bowl, combine the fruit, granulated sugar, cornstarch, and lemon juice. Stir to combine and set aside.

Make the dough:

  1. In a stand mixer bowl, add all dough ingredients. (Note: this can also be done in a large bowl with a hand mixer.)
  2. On a low speed, mix all of the ingredients together until they resemble coarse crumbs. Scrape down the sides of the bowl as needed.

Assemble the bars:

  1. Put half of the coarse crumbs into a greased 8x8 baking dish. Press the crumbs into a solid base using your fingers or the back of a spoon.
  2. Pour the fruit and sugar mixture over the base later.
  3. If using, sprinkle the chopped almonds over the fruit layer.
  4. Sprinkle the remaining crumb mixture evenly over the fruit & almond layer. Do not press down.
  5. Bake for 45-50 minutes, or until the fruit layer is bubbling at the edges and the top crumb layer is golden brown.
  6. Allow to cool, then slice into bars.

Recipe Notes

This version uses strawberries and raspberries, but I have also tried all strawberry, peach & blueberry, all blueberry, and strawberry & peach. All were equally tasty and it is a great way to use up any berries or stone fruit you have around.
