Ingredients
  

  • Ingredients You’ll Need
  • For the Base & Crumble Topping
  • ½ cup unsalted butter melted
  • 1 cup all-purpose flour
  • ¾ cup rolled oats
  • ½ cup granulated sugar
  • ¼ cup light brown sugar packed
  • ½ teaspoon salt
  • For the Strawberry Filling
  • 2 cups roughly chopped fresh strawberries
  • cup granulated sugar
  • 2 tablespoons fresh lemon juice
  • 2 teaspoons cornstarch

Method
 

1. Prep Your Pan

Preheat your oven to 350°F (175°C). Lightly grease or line an 8×8-inch pan with parchment for easy removal.

    2. Mix the Base & Crumble

    In a large bowl, pour in the melted butter. Add flour, oats, both sugars, and salt. Stir until everything looks crumbly but evenly coated.

      👉 Tip: The texture should hold together when pressed—like damp sand.

    3. Build the Crust

    Scoop out about 1 cup of the mixture and set it aside. Press the remaining mixture firmly into the bottom of your prepared pan.

      👉 Press it tight for a sturdy base that won’t fall apart later.

    4. Make the Strawberry Layer

    In another bowl, combine strawberries, sugar, lemon juice, and cornstarch. Toss until the berries are well coated and slightly glossy.

      5. Assemble the Bars

      Spread the strawberry mixture evenly over the crust. Sprinkle the reserved crumble mixture on top.

        6. Bake to Perfection

        Bake for 35–40 minutes, or until the edges are set and the top turns lightly golden. Let cool completely before slicing.

          👉 Cooling is key—this helps the bars set cleanly!

        🔥 Expert Tips for the Best Bars

        • Use ripe, juicy strawberries for maximum flavor

        ❓ FAQs

        Can I use frozen strawberries?
         Yes! Just thaw and drain them first to avoid excess moisture.
        Can I make these gluten-free?
         Swap the flour with a 1:1 gluten-free blend and use certified GF oats.
        Why are my bars too soft?
         They likely need more cooling time. The filling firms up as it sets.
        Can I reduce the sugar?
         You can slightly cut back, but keep in mind it balances the tartness.
