Equipment

  • 8x8-inch baking pan
  • Parchment paper
  • Mixing bowl
  • Spatula
  • Measuring cups and spoons

Ingredients
  

Oat Crumble Base and Topping

  • 1 cup Old fashioned rolled oats
  • 1 cup Whole wheat flour Can substitute all purpose flour
  • 1/3 cup Brown sugar
  • 1/4 teaspoon Salt
  • 1/2 teaspoon Ground cinnamon
  • 6 tablespoons Unsalted butter Melted. Can substitute coconut oil for dairy free option

Strawberry Filling

  • 2 cups Fresh strawberries Finely diced
  • 1 tablespoon Lemon juice
  • 1 tablespoon Cornstarch
  • 1-2 tablespoons Granulated sugar Adjust depending on sweetness of berries

Instructions
 

  • Preheat oven to 375 degrees Fahrenheit. Line an 8x8-inch baking pan with parchment paper, leaving overhang for easy lifting.
  • In a mixing bowl, combine oats, flour, brown sugar, salt, and cinnamon. Stir in melted butter until the mixture becomes crumbly and evenly moistened.
  • Reserve about 1/2 cup of the crumble mixture. Press the remaining mixture firmly into the bottom of the prepared pan to form an even crust.
  • In a separate bowl, toss diced strawberries with lemon juice, cornstarch, and granulated sugar until evenly coated.
  • Spread the strawberry mixture evenly over the crust layer.
  • Sprinkle the reserved crumble mixture over the top, allowing some strawberries to remain visible.
  • Bake for 35 to 40 minutes, or until the top is golden and the filling is bubbling at the edges.
  • Cool completely in the pan before lifting out and slicing into bars. This helps the filling set and prevents crumbling.

Notes

For gluten free bars, use certified gluten free oats and a 1 to 1 gluten free baking flour blend. For dairy free bars, substitute melted coconut oil for butter. If using frozen strawberries, thaw completely and pat dry before mixing to avoid excess moisture. Store in the refrigerator for up to 5 days or freeze individually wrapped bars for up to 2 months.
