Raspberry Crumble Bars
Easy raspberry crumble bars with buttery shortbread base, tart berries, and golden oat topping. Perfect for potlucks and gatherings!
The Bars Everyone Reaches for First
There’s something magical about pulling these raspberry crumble bars out at a gathering—they always disappear first. I love watching people’s faces light up when they bite into that tender shortbread, tart berry filling, and buttery oat crumble all at once. They’re easy enough for a weeknight but impressive enough to bring to any potluck or dinner party.
What I Have Learned
- Don’t skip pressing the base firmly into the pan—a sturdy foundation prevents a soggy bottom layer.
- Keep all your butter cold and work quickly when making both the base and crumble topping. This creates those desirable large clumps and prevents a dense texture.
- The cornstarch is your secret weapon against a runny filling. Don’t reduce it thinking the berries won’t release much liquid—raspberries always surprise you!
- Let these cool completely before cutting. Warm bars will fall apart, but once set, they cut cleanly and hold their shape beautifully.
Variations
- Blackberry Crumble Bars: Swap raspberries for blackberries and add a pinch of cinnamon to the crumble topping for deeper warmth.
- Almond Crumble Bars: Replace 1/4 cup of the oats with sliced almonds and add 1/2 teaspoon almond extract to the crumble mixture.
- Mixed Berry Crumble Bars: Use 2 cups raspberries combined with 1 cup blueberries for a more complex berry flavor and stunning color.

Instructions

Make the Base
Preheat oven to 350°F (175°C). Line a 9x13-inch baking pan with parchment paper. In a bowl, whisk together 1 1/2 cups flour, 1/2 cup granulated sugar, and 1/4 teaspoon salt. Cut in 1/2 cup cold butter until mixture resembles coarse crumbs. Stir in egg yolk until just combined. Press firmly into prepared pan.

Make the Crumble Topping
In another bowl, combine 1 cup oats, 1 cup flour, 3/4 cup brown sugar, and 1/4 teaspoon salt. Add 1/2 cup cold butter, cubed, and 1/2 teaspoon vanilla. Mix with your fingers until large clumps form. Scatter evenly over the raspberry layer.

Bake
Bake for 35-40 minutes, until the crumble is golden brown and the filling bubbles at the edges. Cool completely in the pan on a wire rack, about 1 hour.

Frequently Asked Questions
Can I use frozen raspberries instead of fresh?
Yes, frozen raspberries work beautifully. Use them straight from the freezer without thawing, and increase the cornstarch to 2.5 tablespoons since frozen berries release more liquid. Bake for an extra 5-7 minutes until the filling is bubbling.
Why is my crumble topping soggy?
The most common cause is the berries releasing too much liquid. Make sure your cornstarch is fully whisked into the berry mixture before spreading. Also, don't skip the cooling step—these bars need time to set so the filling firms up.
Can I make these bars ahead of time?
Absolutely! These bars are even better the next day as the flavors deepen. Bake them up to 2 days ahead and store in an airtight container at room temperature. You can also freeze unbaked bars for up to a month—just add 10 extra minutes to the bake time.
