Strawberry Oatmeal Crumble Bars (Printable)

Buttery oat crust and crumble around a bright strawberry filling, baked until golden and cooled before slicing.

# 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 packed light brown sugar
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 oven to 350°F (175°C). Line an 8x8-inch baking pan with parchment paper and lightly grease.
02 - In a large bowl, combine rolled oats, all-purpose flour, light brown sugar, granulated sugar, baking powder, and salt. Stir to blend. Pour in melted butter and mix until the mixture forms a crumbly texture.
03 - Reserve 1 cup of the oat mixture for the topping. Firmly and evenly press the remaining mixture into the prepared baking pan to create the base crust.
04 - In another bowl, mix diced strawberries with lemon juice, cornstarch, and granulated sugar. Gently stir the mixture until the strawberries are evenly coated.
05 - Evenly spread the strawberry filling over the pressed crust.
06 - Evenly distribute the reserved oat crumble over the strawberry layer.
07 - Bake in the preheated oven for 35 to 38 minutes, until the crumble topping is golden and the strawberry filling is bubbling at the edges.
08 - Let the bars cool completely in the pan. Lift out using the parchment paper and cut into 12 even bars.

# Cooking Tips:

01 -
  • The crumble comes out both buttery and perfectly crisp, a texture secret I can never resist sharing.
  • You can swap the fruit with whatever you have on hand, so it's impossible to get bored.
02 -
  • If you rush the cooling, the bars will collapse into a delicious-but-messy heap (I learned that one sticky summer afternoon).
  • One day, I doubled the berries on a whim and discovered a gloriously juicy, almost pie-like dessert—just be prepared for softer slices.
03 -
  • Roast the oats for a few minutes before mixing for extra nutty flavor.
  • A pinch of cinnamon in the crumble can completely change the mood of your bars.
