These bars sandwich a sweet-tart fruit jam between two layers of buttery peanut butter oat crumble, then bake until golden and set. They slice cleanly once cooled, making them a sturdy lunchbox treat or an easy make-ahead snack for busy mornings.
Ingredients
- 2 1/2 cups old-fashioned rolled oats
- 1 1/2 cups all-purpose flour
- 3/4 cup packed brown sugar
- 1/2 teaspoon baking soda
- 1/2 teaspoon fine sea salt
- 1 cup unsalted butter, melted
- 1 teaspoon vanilla extract
- 1 cup creamy peanut butter
- 3/4 cup strawberry jam
Method
-
Preheat the oven to 350°F and line a 9x13-inch baking pan with parchment paper, leaving an overhang on the sides.
-
In a large bowl, whisk together the oats, flour, brown sugar, baking soda, and salt.
-
Stir in the melted butter and vanilla extract until the mixture is evenly moistened and crumbly.
-
Add the peanut butter to the oat mixture and mix until just combined, keeping some streaks for texture.
-
Press two-thirds of the oat mixture firmly and evenly into the bottom of the prepared pan.
-
Spread the strawberry jam evenly over the pressed oat base, leaving a thin border at the edges.
-
Crumble the remaining oat mixture evenly over the jam layer, pressing lightly so it adheres.
-
Bake until the top is golden brown and the edges are set, 35 to 40 minutes.
-
Cool the bars completely in the pan on a wire rack before lifting out using the parchment overhang.
-
Slice into 16 bars using a sharp knife, wiping the blade clean between cuts.
