Strawberry Oatmeal Crumble Bars
Ingredients
For the Crust and Crumble Topping:
- ½ cup unsalted butter, melted
- 1 cup all-purpose flour
- ¾ cup old-fashioned whole-rolled oats
- ½ cup granulated sugar
- ¼ cup light brown sugar, packed
- ½ teaspoon salt (or to taste)
For the Strawberry Layer:
- 2 cups coarsely chopped fresh strawberries
- ⅓ cup granulated sugar
- 2 tablespoons lemon juice
- 2 teaspoons corn starch
Instructions
- Prepare the Pan:
- Preheat your oven to 350°F (175°C).
- Line an 8-inch square baking pan with aluminum foil and spray with cooking spray for easy cleanup. Set aside.
- Make the Crust and Crumble Topping:
- In a large, microwave-safe bowl, melt the butter (about 1 minute on high power).
- Add the flour, oats, granulated sugar, brown sugar, and salt. Stir until the mixture is combined and has a dry, sandy texture with some larger crumble pieces.
- Reserve 1 heaping cup of the mixture to use as the crumble topping.
- Transfer the remaining mixture to the prepared pan. Use a spatula or your fingers to press it down firmly, creating an even, flat crust.
- Prepare the Strawberry Layer:
- In the same bowl used for the crust and crumble, combine the chopped strawberries, sugar, lemon juice, and corn starch. Toss until the ingredients are well mixed. It’s okay if the sugar hasn’t fully dissolved as it will liquefy during baking.
- Evenly spread the strawberry mixture over the prepared crust.
- Add the Crumble Topping:
- Take the reserved crumble mixture and sprinkle it evenly over the strawberry layer. For larger crumble pieces, squeeze the mixture in your palm before sprinkling.
- Bake the Bars:
- Bake in the preheated oven for about 50 minutes, or until the edges are set and the center is just set. The crumble topping should be very pale golden, and the strawberry filling should be bubbling around the edges. If your strawberries are very juicy, baking time may be slightly longer.
- Cool and Serve:
- Place the pan on a wire rack and allow the bars to cool completely, at least 1 hour, before slicing and serving. Cutting the bars before they are fully cooled can result in a messy, falling-apart dessert.
Description and Tips
Tips:
- Butter: Use unsalted butter to better control the salt level in the recipe.
- Strawberries: Fresh strawberries work best for a vibrant flavor and color. If using frozen strawberries, thaw them first and drain any excess liquid.
- Cooling: Ensure the bars are completely cooled before cutting to avoid a messy presentation.
- Storage: These bars keep well at room temperature for up to 2 days, or in the refrigerator for up to a week. They can also be frozen for longer storage; simply thaw before serving.
Perfect for a summer dessert, brunch treat, or any time you want a fruity, crumbly delight, these bars are sure to be a hit!
