Strawberry Oatmeal Crumble Bars (Printable)
Sweet strawberry filling beneath a buttery oat crumble, baked until golden, cooled and sliced into 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
# Directions:
01 - Preheat the 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, light brown sugar, granulated sugar, baking powder, and salt. Add the melted butter and mix until the mixture becomes crumbly.
03 - Reserve 1 cup of the oat mixture for the topping. Press the remaining mixture evenly and firmly into the prepared pan to form the crust.
04 - In a separate bowl, combine diced fresh strawberries with lemon juice, cornstarch, and granulated sugar. Gently stir to coat the fruit thoroughly.
05 - Spread the strawberry filling evenly over the crust in the pan.
06 - Sprinkle the reserved oat mixture evenly over the strawberry layer.
07 - Bake for 35 to 38 minutes, or until the crumble top is golden and the fruit filling is bubbling at the edges.
08 - Allow the bars to cool completely in the pan. Lift out using the parchment paper and cut into individual portions.
# Expert Tips:
01 -
- This recipe rewards you with soft, jammy fruit and a crumbly oat topping you can never quite get enough of.
- Whenever I make these, the pan disappears within hours, even among people who claim not to like dessert.
02 -
- I once rushed and cut these bars while they were still warm, only to end up with delicious but crumbly piles—patience pays off.
- Chilling the bars before slicing makes for clean, bakery-worthy squares and locks in the gooey filling.
03 -
- Use parchment overhang to lift the bars in one piece—less mess and easier slicing.
- If you want brighter color, don’t overmix the berries—stir just until coated.
