Buttery oat crust, vibrant strawberry filling and crunchy oat crumble — simple, shareable baked bars.

# What You'll Need:

→ Crust and Crumble

01 - 1 1/2 cups rolled oats
02 - 1 1/4 cups all-purpose flour
03 - 1/2 cup light brown sugar, packed
04 - 1/4 cup granulated sugar
05 - 1/2 teaspoon baking powder
06 - 1/4 teaspoon salt
07 - 3/4 cup unsalted butter, melted

→ Strawberry Filling

08 - 2 cups diced fresh strawberries
09 - 1 tablespoon lemon juice
10 - 2 teaspoons cornstarch
11 - 1/3 cup granulated sugar

# How to Make:

01 - Preheat oven to 350°F. Line an 8x8-inch baking pan with parchment paper and lightly grease.
02 - In a large mixing bowl, combine rolled oats, all-purpose flour, brown sugar, granulated sugar, baking powder, and salt.
03 - Pour melted unsalted butter over the dry mixture and stir until the mixture resembles coarse crumbs.
04 - Reserve 1 cup of the oat mixture for the topping. Press the remaining mixture firmly and evenly into the base of the prepared pan.
05 - In a separate bowl, gently toss diced strawberries with lemon juice, cornstarch, and granulated sugar until evenly coated.
06 - Spread the strawberry mixture evenly across the crust in the baking pan.
07 - Sprinkle the reserved oat mixture evenly over the strawberry layer, covering the fruit.
08 - Bake in the preheated oven for 35 to 38 minutes or until the crumble topping is golden and the filling bubbles around the edges.
09 - Allow the bars to cool completely in the pan. Lift out using the parchment paper and slice into individual bars.

# Expert Suggestions:

01 -
  • Every bite mixes crispy oat crust with a gooey strawberry center and a buttery crumble—yes, it really is as good as it sounds.
  • I love how you can swap in whichever berries you have on hand and it never fails to bring out smiles.
02 -
  • If you try to slice the bars before they’re cool, you’ll end up with a delicious but gooey mess all over your counter.
  • I learned that chopping strawberries into small dice actually keeps the filling jammy and helps the bars hold together.
03 -
  • Don’t cut corners on cooling time—the bars stay sliceable and picture-perfect.
  • A tiny extra pinch of salt in the crumble takes the flavor from good to unforgettable.
