Ingredients
  

For the Crust and Topping

  • 1.5 cups gluten-free all-purpose flour blend with xanthan gum if your blend doesn’t include it
  • 1 cup gluten-free rolled oats
  • 0.5 cups almond flour
  • 0.5 cups packed brown sugar
  • 0.25 cups granulated sugar
  • 1 tsp baking powder
  • 0.25 tsp fine salt
  • 0.75 cups cold butter, cubed or coconut oil for dairy-free
  • 1 large egg
  • 1 tsp vanilla extract

For the Raspberry Filling

  • 2 cups fresh or frozen raspberries
  • 0.33 cups granulated sugar for filling
  • 1 tbsp cornstarch
  • 1 tbsp lemon juice

Instructions
 

Preparation

  • Preheat the oven to 350°F (175°C). Line an 8x8-inch pan with parchment paper, leaving an overhang to lift bars out later.
  • In a large bowl, whisk together the gluten-free flour, oats, almond flour, brown sugar, baking powder, and salt.
  • Cut in the cold butter with a pastry cutter or pulse in a food processor until the mixture resembles coarse crumbs.
  • Stir in the egg and vanilla until it forms a crumbly dough. Press about two-thirds of the mixture evenly into the prepared pan to form the bottom crust.

Cooking

  • In a small saucepan over medium heat, combine raspberries, 1/3 cup sugar, cornstarch, and lemon juice. Cook, stirring often, until the mixture thickens and the raspberries break down (3 to 5 minutes). Cool slightly.
  • Spoon the raspberry filling over the crust and spread gently. Crumble the remaining dough over the top, leaving some larger chunks for texture.
  • Bake for 30–35 minutes, or until the top is golden and the filling is bubbling.
  • Let cool completely in the pan, then chill for at least 1 hour before cutting into bars to ensure clean slices.

Notes

Keep the butter cold to create a flaky, tender crumb. Use gluten-free oats labeled 'certified gluten-free' if you are highly sensitive. Chill the bars before slicing; warm jam can smear and make slices messy. If the top browns too quickly, tent with foil for the last 10 minutes. For lower sugar, reduce filling sugar by a tablespoon or two and taste the fruit first.
