5-Ingredient Raspberry Crumble Bars

Some recipes feel like old friends—the kind you tuck into a family binder and return to again and again. These raspberry crumble bars are exactly that. They remind me of the simple church potluck desserts I grew up with in the Midwest: nothing fancy, just honest, buttery, fruity goodness that disappears the moment the pan hits the table.

With only a handful of pantry staples and a jar of raspberry jam, you’ve got a dessert that works for after-school snacks, Sunday dinners, or even as a sweet surprise for a neighbor. They’re especially fun to bake with kids—the layers are easy to press and crumble, and there’s something special about watching them proudly serve a treat they helped make.

Serve them as-is for a rustic delight, or dress them up slightly warm with a scoop of vanilla ice cream or a dollop of whipped cream. A sprinkle of powdered sugar adds a pretty finish. For brunch, cut them into smaller squares and set them alongside fruit, yogurt, and eggs. They also travel well in lunchboxes or picnic baskets—just let them cool completely so they hold their shape.
5-Ingredient Raspberry Crumble Bars
📝 Ingredients
| Ingredient | Amount | Notes |
|---|---|---|
| All-purpose flour | 1½ cups | |
| Old-fashioned rolled oats | 1½ cups | |
| Granulated sugar | ¾ cup | |
| Unsalted butter | ¾ cup (1½ sticks), melted & slightly cooled | |
| Raspberry jam or preserves | 1 cup |
🍴 Directions
- Preheat oven to 350°F (175°C). Grease an 8×8-inch pan or line with parchment, leaving overhang for easy lifting.
- Mix dry ingredients: In a bowl, combine flour, oats, and sugar.
- Add butter: Pour melted butter over mixture; stir until evenly moistened and crumbly. It should hold together when pressed.
- Form crust: Press two-thirds of the mixture firmly into the pan.
- Add jam: Spread raspberry jam evenly over the crust.
- Top & bake: Sprinkle remaining crumb mixture over jam. Bake 28–32 minutes, until golden and bubbly at the edges.
- Cool & cut: Let cool completely in the pan on a wire rack. Lift out using parchment, slice into 12 squares (or smaller for a crowd).
Storage: Keep in an airtight container at room temperature for up to 3 days, or refrigerate for a firmer texture.
✨ Tip: For extra indulgence, serve warm with ice cream or whipped cream. For a lighter finish after dinner, pair with a crisp green salad before dessert.
