Ingredients

Scale
  • 1 1/2 cups old-fashioned rolled oats (180g)
  • 1 1/4 cups all-purpose flour (150g) (can swap with almond flour for gluten-free option)
  • 3/4 cup packed light brown sugar (150g)
  • 1/2 teaspoon baking powder
  • 1/4 teaspoon salt
  • 12 tablespoons unsalted butter, melted and slightly cooled (170g) (use dairy-free butter if needed)
  • 1 1/2 cups fresh or frozen strawberries, hulled and chopped (225g)
  • 1 cup fresh or frozen blueberries (150g)
  • 1 cup fresh or frozen raspberries (150g)
  • 2/3 cup granulated sugar (135g) (adjust to taste)
  • 2 tablespoons cornstarch (16g)
  • 1 tablespoon fresh lemon juice
  • 1 teaspoon vanilla extract (optional)

Instructions

  1. Preheat your oven to 350°F (175°C). Lightly grease a 9×13 inch baking pan or line it with parchment paper.
  2. In a large bowl, whisk together rolled oats, all-purpose flour, brown sugar, baking powder, and salt.
  3. Pour in the melted butter and stir with a wooden spoon or spatula until the mixture holds together loosely and feels crumbly but sticks when pressed.
  4. Reserve about 1 1/2 cups of the oat mixture for the topping. Press the remaining mixture firmly into the bottom of the prepared pan.
  5. In a separate bowl, gently toss the chopped strawberries, blueberries, and raspberries with granulated sugar, cornstarch, lemon juice, and vanilla extract.
  6. Spread the berry filling evenly over the oat crust layer without pressing down.
  7. Sprinkle the reserved oat topping evenly over the berries, allowing some larger chunks for crispiness.
  8. Bake for 45-50 minutes until the topping is golden brown and the berry filling is bubbling at the edges.
  9. Cool completely on a wire rack before slicing into bars. Chilling in the fridge for 30 minutes can help if impatient.
  10. Slice into squares and serve warm or at room temperature.

Notes

[‘Use cold butter for a flakier texture by chilling the oat topping mixture for 10 minutes before pressing down.’, ‘Do not overmix the berry filling to keep some berry pieces intact.’, ‘Check bars at 40 minutes if your oven runs hot to prevent over-browning.’, ‘Press crust firmly but sprinkle topping loosely for best texture contrast.’, ‘Use parchment paper for easier removal and intact edges.’, ‘Cool bars completely before slicing to avoid a gooey mess.’, ‘Bars can be stored in an airtight container in the refrigerator for up to 5 days or frozen for up to 3 months.’]
