How to Make Strawberry Crumble Bars
Prep Time: 15 minutes | Cook Time: 45 minutes | Total Time: 60 minutes | Servings: 12 bars
Ingredients
- For the Crust & Crumble:
- 2 cups all-purpose flour
- 1 cup old-fashioned rolled oats
- 1 cup packed light brown sugar
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 1 cup (2 sticks) unsalted butter, melted and slightly cooled
- For the Strawberry Filling:
- 3 cups fresh strawberries, hulled and diced
- 1/3 cup granulated sugar
- 2 tablespoons cornstarch
- 1 tablespoon lemon juice
- 1 teaspoon vanilla extract
Instructions
- Preheat your oven to 350°F (175°C). Line an 8×8 or 9×9 inch baking pan with parchment paper, leaving an overhang on two sides for easy removal.
- In a large bowl, whisk together the flour, oats, brown sugar, baking soda, and salt. Pour the melted butter over the dry ingredients and stir until the mixture is evenly moistened and crumbly.
- Set aside about 1 1/2 cups of the crumble mixture for the topping. Press the remaining mixture firmly and evenly into the bottom of the prepared pan to form the crust.
- In a medium bowl, gently toss the diced strawberries with granulated sugar, cornstarch, lemon juice, and vanilla extract until well combined.
- Spread the strawberry filling evenly over the pressed crust in the pan. Sprinkle the reserved crumble topping evenly over the strawberry layer.
- Bake for 40-45 minutes, or until the topping is golden brown and the filling is bubbly around the edges. Place the pan on a wire rack and allow the strawberry crumble bars to cool completely before slicing into squares.
Tips
- For clean cuts, chill the baked and cooled pan in the refrigerator for about an hour before slicing.
- If using frozen strawberries, do not thaw them first; toss them frozen with the filling ingredients and add 5-10 minutes to the bake time.
- For a nutty flavor, add 1/2 cup of chopped pecans or almonds to the crumble mixture.
Serving and Storage Suggestions
These bars are delicious served at room temperature or slightly warmed. They pair wonderfully with a scoop of vanilla ice cream or a dollop of whipped cream for an extra-indulgent dessert. They also make a fantastic sweet breakfast or afternoon snack with a cup of coffee or tea.
