Raspberry Nutnola Crumble Bars

Square Root products

These Raspberry Nutnola Crumble Bars are the perfect summertime treat - portable, perfectly sweet and salty, and even better when eaten with friends! They are so simple to make - the base and crumble are made with a mixture of oats, gluten free flour flour, butter, brown sugar, Lemon Blueberry Nutnola, and vanilla, and the raspberries cook down to be so jammy and sweet. YUM!


For the base/crumble topping

  • 1 1/2 cups gluten free oats
  • 1 1/4 cups + 1 tablespoon all-purpose gluten free flour flour
  • 1/2 teaspoon baking soda
  • 3/4 teaspoon salt
  • 1 cup unsalted butter, melted and cooled
  • 1 cup light brown sugar, loosely packed
  • 1 teaspoon vanilla extract
  • 1/2 cup Square Root Lemon Blueberry Nutnola, coarsely chopped

For the raspberry filling

  • 12 ounces raspberries
  • 1 tablespoon arrowroot flour
  • 1 tablespoon sugar
  • 1 tablespoon lemon juice
  • pinch of salt


  1. Preheat your oven to 350℉. Spray an 8x8 square metal or glass baking dish with nonstick spray, line with parchment paper, and spray again. Set aside.

  2. In a medium mixing bowl, whisk together the oats, flour, baking soda, and salt until combined. In a separate, large mixing bowl, whisk together the melted butter, brown sugar, and vanilla until smooth. Add the dry ingredients to the wet, mixing with a rubber spatula to combine. Fold in the chopped nutnola. Once incorporated, let the dough sit for 5 minutes, to allow the flour to absorb the wet ingredients. If the dough seems too loose after this time, add an additional tablespoon of flour at a time, until mixture resembles wet sand consistency. Set aside.

  3. In a medium bowl, stir together the raspberries, arrowroot, sugar, lemon juice, and a pinch of salt until combined. Set aside.

  4. Press a little over half of the base/crumble mixture into the bottom of the pan, to create an even and smooth "crust". Add the raspberry mixture evenly over the crust. Crumble the remaining base/crumble mixture over top. Bake for 35 minutes, or until crumble is golden brown, and the center is set. Let cool completely before cutting into bars.
