Ingredients
- Crumble Base & Topping
- 1½ cups all-purpose flour
- 1 cup rolled oats
- ¾ cup granulated sugar
- 1 teaspoon baking powder
- ¼ teaspoon salt
- ¾ cup cold unsalted butter cubed
- 1 teaspoon vanilla extract
- Strawberry Filling
- 2½ cups fresh strawberries hulled and diced
- ¼ cup granulated sugar
- 1 tablespoon lemon juice
- 1 tablespoon cornstarch
Instructions
- Prep
- Preheat oven to 350°F (175°C).
- Line an 8×8-inch baking pan with parchment paper, leaving overhang for easy removal.
- Make the Crumble
- In a large bowl, mix flour, oats, sugar, baking powder, and salt.
- Cut in cold butter using a pastry cutter or fork until the mixture resembles coarse crumbs.
- Stir in vanilla extract.
- Press ⅔ of the crumble mixture firmly into the bottom of the prepared pan.
- Strawberry Filling
- In a separate bowl, toss strawberries with sugar, lemon juice, and cornstarch.
- Spread strawberry mixture evenly over the crust.
- Assemble & Bake
- Sprinkle the remaining crumble evenly over the strawberries.
- Bake for 40–45 minutes, until the top is golden and the filling is bubbling.
- Remove from oven and cool completely in the pan.
Notes
- Cooling fully is essential—bars slice cleanly once the filling sets.
- Cold butter is key for a crumbly texture.
- Fresh strawberries give the best flavor and consistency.
- Bars firm up even more after chilling.
