Ingredients
  

For the Crust & Crumble Topping
  • 2 cups gluten-free rolled oats Use certified gluten-free oats for the best texture and safety.
  • 1 cup almond flour Adds a subtle nutty flavor and tender crumb.
  • 1/2 cup brown sugar Provides natural sweetness and helps achieve a golden crust.

Method
 

How to Make Gluten-Free Strawberry Oat Crumble Bars
  1. Preheat your oven to 350°F and line an 8x8-inch pan with parchment paper.
  2. In a medium bowl, whisk gluten-free oats, almond flour, brown sugar, ground cinnamon, and a pinch of salt until well combined.
  3. Use chilled butter cut into small cubes, then toss with the dry mix until pea-sized crumbs form for a tender, flaky crumble.
  4. Press half of the oat mixture firmly into the prepared pan and bake for 10 minutes, until the edges just start to turn golden brown and set.
  5. Gently combine chopped strawberries with granulated sugar, lemon juice, and cornstarch until berries release juice for perfect filling consistency.
  6. Spread the strawberry filling evenly over the warm crust, then sprinkle the remaining oat crumble mixture on top to fully cover the fruit layer.
  7. Bake for 25–30 minutes until the topping turns deep golden brown and the filling bubbles, then cool completely to room temperature in the pan.
