2 cups certified gluten-free rolled oats
2/3 cups certified gluten-free oat flour
1/2 cup King Arthur gluten-free flour
1 cup brown sugar
1/2 tsp sea salt
1/2 tsp baking soda
3/4 cup unsalted butter, room temperature
1 1/2 cups blueberries
1/2 cup cane sugar
1 tbsp freshly squeezed lemon juice
1 tbsp cornstarch
1 tbsp water


  1. Preheat the oven to 325 degrees. Spray and 9'x13' baking pan with canola oil spray.
  2. In a mixer, combine oats, flours, brown sugar, salt, baking soda, and butter. Divide the oat mixture in half. Press half the mixture into the bottom of the prepared pan.
  3. In a medium saucepan, over medium-high heat, combine blueberries, sugar, and lemon juice. Bring to a boil.
  4. In a small bowl, whisk together cornstarch and water to form a slurry. Add to boiling blueberry mixture. Continue cooking until thickened. Cool slightly before spreading the blueberry mixture over the crust. Sprinkle the remaining flour/oat mixture over top.
