Ingredients
For the Crust & Crumb:
- 1 cup (2 sticks) unsalted butter, melted and cooled slightly
- 1 cup granulated sugar
- 1 tsp vanilla extract
- 2 ½ cups all-purpose flour
- ¼ tsp salt
- Zest of 1 lemon (optional, but so good)
For the Raspberry Filling:
- ¾ cup raspberry preserves or jam
- 1 ½ cups fresh or frozen raspberries (don’t thaw if using frozen)
- 1 tbsp cornstarch
- 1 tbsp lemon juice
Tip: Use seedless jam for a smoother texture, or keep the seeds for a more rustic feel.
Instructions
1. Preheat the Oven
Preheat your oven to 350°F (175°C). Line an 8×8-inch or 9×9-inch baking pan with parchment paper, leaving an overhang for easy lifting.
2. Make the Crust and Crumb
In a large bowl, stir together melted butter, sugar, and vanilla until combined.
Add flour, salt, and lemon zest. Stir until a soft, crumbly dough forms—like wet sand that holds together when pressed.
Set aside ¾ cup of the dough for the topping. Press the remaining dough firmly into the bottom of your prepared pan.
Use the bottom of a measuring cup or your fingers to create an even layer.
3. Make the Raspberry Filling
In a medium bowl, gently mix together raspberry jam, raspberries, cornstarch, and lemon juice.
Spoon the filling evenly over the crust.
4. Add the Crumb Topping
Crumble the reserved dough over the raspberry layer, leaving some larger clumps for texture.
Don’t worry about covering it completely—the filling should peek through.
5. Bake
Bake for 35–40 minutes, or until the top is lightly golden and the filling is bubbling.
Let cool completely in the pan. For cleaner slices, chill for 30 minutes before cutting.
How to Serve
- Dust with powdered sugar for a bakery-style finish
- Serve slightly warm with a scoop of vanilla ice cream
- Add to a dessert tray or brunch spread
- Enjoy chilled for a firmer, chewier bar (so good right from the fridge!)
- Pack into lunchboxes or picnic baskets for a sweet, portable treat
Tips for Success
- Let them cool completely before slicing for clean edges
- Don’t skimp on the crumble – big clusters = great texture
- Use parchment paper with overhang so you can lift the bars out easily
- Want extra tang? Add a pinch of lemon zest to the raspberry filling
- Use quality jam – it really makes a difference in flavor
Variations
Mixed Berry Bars
Use a combo of raspberries, blackberries, and blueberries.
Almond Twist
Add ½ tsp almond extract to the crust and sprinkle with sliced almonds before baking.
Oat Crumb Topping
Swap ½ cup of the flour for rolled oats for a heartier topping.
Gluten-Free Option
Use a 1:1 gluten-free flour blend in place of all-purpose flour.
Vegan-Friendly
Use plant-based butter—look for one with a similar fat content for best texture.
Storage
Room Temp: Store in an airtight container for up to 3 days.
Fridge: Keeps for up to 5–6 days. Chilling makes the bars firmer and great for clean slicing.
Freezer: Freeze tightly wrapped bars in a container for up to 2 months. Thaw at room temp or in the fridge before serving.
FAQ
Can I use frozen raspberries?
Yes! Use straight from frozen—don’t thaw, or they’ll release too much liquid.
Can I double the recipe?
Absolutely. Bake in a 9×13-inch pan and increase baking time by about 5–10 minutes.
Can I use other jams?
Totally. Strawberry, blackberry, or apricot all work beautifully.
How do I get clean cuts?
Chill the bars first and wipe your knife between cuts for perfect squares.
