Strawberry Oatmeal Crumble Bars (Printable)

Buttery oat crust, vibrant strawberry filling, and golden crumble for a handheld berry dessert.

# Ingredient List:

→ 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

# Steps:

01 - Preheat 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.
03 - Pour in melted unsalted butter and mix until the mixture is crumbly.
04 - Reserve 1 cup of the oat mixture for topping. Press the remaining mixture evenly and firmly into the prepared pan to create the base layer.
05 - In another bowl, gently stir together diced fresh strawberries, lemon juice, cornstarch, and granulated sugar until well coated.
06 - Evenly spread the strawberry filling over the bottom crust.
07 - Sprinkle the reserved oat mixture evenly over the strawberry layer.
08 - Bake for 35 to 38 minutes or until the oat crumble is golden brown and the filling is bubbling.
09 - Allow bars to cool completely in the pan. Lift out using the parchment paper and cut into portions.

# Expert Tips:

01 -
  • The warm strawberry filling seeps into the nutty crumble, making every bite comfortingly gooey.
  • This recipe is just as good for potlucks as it is for solo, sneak-from-the-pan afternoons.
02 -
  • If you don’t let them cool fully, you’ll end up with a squishy, delicious mess instead of neat squares.
  • Once I tried using only sugar in the crust—turns out brown sugar is key for that soft, chewy bite.
03 -
  • Melted butter in the crumble ensures an even golden hue and makes pressing so much easier.
  • A squeeze of lemon over the finished bars can freshen up any batch, especially if your berries weren’t the sweetest.
