Ingredients
  

  • 1 1/2 cups gluten-free rolled oats certified gluten-free preferred
  • 1 cup almond flour fine ground works best
  • 2/3 cup dark brown sugar packed
  • 1/2 cup unsalted butter diced, room temperature; use coconut oil for dairy-free
  • 3 cups fresh strawberries chopped into small pieces
  • 1/4 cup pure maple syrup Grade A preferred
  • 1 teaspoon vanilla extract pure recommended
  • 1 whole fresh lemon zest and juice separated
  • 1 tablespoon arrowroot starch or cornstarch

Instructions
 

  • Step 1: Prepare the Crust
  • Preheat oven to 350°F (175°C). Line an 8x8-inch baking pan with parchment paper, leaving overhang.
  • In a large mixing bowl, combine oats, almond flour, and dark brown sugar.
  • Add diced butter and work into the mixture with your hands until it resembles coarse crumbs and holds together when pressed.
  • Press two-thirds of the mixture into the pan, pressing firmly to form an even crust.
  • Bake for 15 minutes or until lightly golden. Remove and set aside.
  • Step 2: Make the Strawberry Filling
  • In a medium saucepan, combine chopped strawberries, maple syrup, vanilla extract, and lemon zest.
  • Cook over medium-high heat for 10–12 minutes, stirring occasionally, until the mixture becomes thick and jammy.
  • In a small bowl, whisk lemon juice with arrowroot starch until smooth.
  • Stir the slurry into the hot strawberry mixture and remove from heat. It will thicken quickly.
  • Step 3: Assemble and Bake
  • Spread the strawberry filling evenly over the pre-baked crust.
  • Crumble the remaining oat mixture over the top.
  • Bake for 25–30 minutes, until the top is golden and the filling bubbles at the edges.
  • Cool completely in the pan for at least 2 hours. For cleaner cuts, refrigerate for 30 minutes before slicing.
  • Step 4: Serve
  • Cut into 12 bars using a sharp knife. Clean between cuts for neat slices.
  • Serve slightly warm, room temperature, or chilled with a dollop of Greek yogurt if desired.
