These Raspberry Oatmeal Crumble Bars are buttery, fruity, and full of texture—made with oats, brown sugar, and raspberry jam for the perfect layered treat.

Ingredients

1 cup (125 g) all-purpose flour

1 cup (90 g) old-fashioned oats

½ cup (100 g) light brown sugar, packed

¼ tsp baking soda

⅛ tsp kosher salt

½ cup (113 g / 1 stick) unsalted butter, melted

¾ cup (240 g) raspberry jam (preferably seedless for smooth layers)

Instructions

Preheat Oven & Prep Pan
Preheat oven to 350°F (175°C). Line an 8×8-inch baking dish with parchment paper, leaving a slight overhang for easy lifting.

Mix Dry Ingredients
In a medium bowl, combine flour, oats, brown sugar, baking soda, and salt. Mix well.

Add Butter to Form Crumble
Pour melted butter over the dry mixture. Use a fork or pastry cutter to blend until crumbly. Mixture should resemble coarse crumbs with no dry pockets.

Form the Base
Press ⅔ of the oat mixture firmly into the bottom of the prepared pan to form an even crust.

Add Jam Layer
Gently spread raspberry jam evenly over the crust.

Top with Crumble
Sprinkle remaining oat mixture evenly on top of the jam.

Bake & Cool
Bake for 30–35 minutes, or until the top is golden brown. Let cool completely in the pan before cutting into bars.

Notes

Storage: Keep bars in an airtight container at room temperature for 3 days or refrigerate for up to a week.

Freezer-Friendly: Freeze individually wrapped bars for up to 3 months.

Flavor Variations: Swap raspberry jam for strawberry, apricot, or blueberry.

Add-Ins: Mix in chopped nuts or shredded coconut to the crumble for added texture.
