Berries, Lemons, and Long Summer Evenings

Every July my neighbor leaves a basket of just-picked raspberries on my porch, and these bars are how I say thank you.

Learn more about DanyRecipes and why I bake with whatever the season hands me. These raspberry lemon bars pair a buttery shortbread crust with a tangy lemon custard studded with fresh berries.

Why Raspberry and Lemon Belong Together

Raspberries bring a juicy, floral sweetness that softens the lemon’s sharp edge, and their ruby color makes every square look like summer. Tossing the berries in a little flour keeps them from sinking or turning the filling watery.

This lemon bars recipe fits a standard 9×13 pan and makes a generous batch for picnics and barbecues. It is one of my favorite lemon desserts for warm weather, and it pairs nicely with my chewy thumbprint lemon curd cookies on a dessert table.

Fresh Summer Ingredients

For the crust:

• 2 cups all purpose flour
• 1/2 cup powdered sugar, plus extra for dusting
• 1/4 teaspoon fine salt
• 1 cup (2 sticks) cold unsalted butter, cubed

For the raspberry lemon filling:

• 1 3/4 cups granulated sugar
• 4 large eggs, at room temperature
• 2/3 cup fresh lemon juice (about 4 lemons), strained
• 2 tablespoons lemon zest, finely grated
• 1/4 cup all purpose flour
• Pinch of salt
• 1 1/2 cups fresh raspberries, tossed with 1 tablespoon flour

Easy Steps to Raspberry Lemon Bars

STEP 1

Heat the oven to 350°F and line a 9×13 pan with parchment, leaving an overhang on two sides.

STEP 2

Whisk the flour, powdered sugar, and salt, then cut in the cold butter until the mixture forms soft, damp crumbs.

STEP 3

Press the dough firmly into the pan and bake for 18 to 20 minutes until lightly golden.

STEP 4

Whisk the sugar, eggs, lemon juice, zest, flour, and salt until completely smooth.

STEP 5

Pour the filling over the warm crust, scatter the floured raspberries on top, and bake for 25 to 30 minutes until the center barely wobbles.

STEP 6

Cool on a rack, chill for at least 3 hours, then dust with powdered sugar and slice into squares.

Serving Ideas and Easy Twists

• Serve chilled with a few extra fresh raspberries on top.
• Add a spoonful of whipped cream or vanilla yogurt on the side.
• Pair with my crispy shortbread lemon curd cookies for a buttery crunch beside the juicy bars.
• Swap half the raspberries for blackberries or blueberries for a mixed berry pan.
• Cut into small squares and pack in a tin for picnics.

Pro Tips

• Toss the raspberries in flour so they stay put and do not bleed into the custard.
• Scatter the berries gently, since crushed berries turn the filling pink and watery.
• Use frozen raspberries straight from the freezer, without thawing, if fresh are out of season.
• Pull the pan when the center still wobbles, since it firms up as it chills.
• Chill for a full 3 hours so the berry filled custard slices cleanly.
• Dust with powdered sugar right before serving so it stays bright white.

Ingredients

  

Shortbread Crust

• 2 cups all-purpose flour
• 1/2 cup powdered sugar plus extra for dusting
• 1/4 tsp fine salt
• 1 cup unsalted butter 2 sticks, cold and cubed

Raspberry Lemon Filling

• 1 3/4 cups granulated sugar
• 4 large eggs at room temperature
• 2/3 cup fresh lemon juice about 4 lemons, strained
• 2 tbsp lemon zest finely grated
• 1/4 cup all-purpose flour
• 1 pinch salt
• 1 1/2 cups fresh raspberries tossed with 1 tablespoon flour
• 1 tbsp all-purpose flour for coating the raspberries

Equipment

• 9×13-inch Baking Pan
• Parchment paper
• Mixing bowls
• Whisk
• Pastry Cutter
• Wire Cooling Rack

Method

 

1. Preheat the oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving an overhang on two sides for easy removal.
2. Whisk together the flour, powdered sugar, and salt for the crust. Cut in the cold cubed butter until the mixture forms soft, damp crumbs.
3. Press the crust mixture firmly and evenly into the prepared pan. Bake for 18–20 minutes, until lightly golden.
4. In a mixing bowl, whisk together the granulated sugar, eggs, fresh lemon juice, lemon zest, flour, and salt until completely smooth.
5. Gently toss the fresh raspberries with 1 tablespoon of flour until lightly coated. This helps prevent them from sinking or releasing too much moisture into the filling.
6. Pour the lemon filling over the warm crust. Scatter the floured raspberries evenly over the top, taking care not to crush them.
7. Bake for 25–30 minutes, until the center barely wobbles when the pan is gently nudged.
8. Transfer the pan to a wire rack and let it cool completely. Refrigerate for at least 3 hours, then dust with powdered sugar. Lift the bars out using the parchment overhang and slice into squares.

Notes

Serve chilled with fresh raspberries, whipped cream, or vanilla yogurt. For a mixed berry variation, replace half the raspberries with blackberries or blueberries. You can also swirl 1/3 cup of seedless raspberry jam into the filling for a marbled appearance. If using frozen raspberries, add them straight from the freezer without thawing and extend the baking time by 3–5 minutes if needed. Make sure fresh berries are dry before coating them in flour. Store covered in the refrigerator for up to 4 days, with parchment between layers. Freeze undusted bars, tightly wrapped, for up to 2 months and thaw overnight in the refrigerator. Dust with powdered sugar just before serving.

FAQs

Can I use frozen raspberries?
Yes, add them straight from the freezer and bake 3 to 5 minutes longer. Thawing makes them release juice and turn the filling runny.

How should I store the bars?
Cover and refrigerate for up to 4 days, with parchment between layers. Berries add moisture, so they are best within that window.

Can I freeze them?
Yes, freeze the undusted bars wrapped tightly for up to 2 months. Thaw overnight in the fridge and dust before serving.

Why is my filling watery around the berries?
The berries were likely wet or not tossed in flour. Pat them dry, coat them lightly, and make sure the center is set before cooling.

Can I use raspberry jam instead?
Yes, swirl 1/3 cup of seedless jam into the filling for a smoother, sweeter bar. It will look marbled instead of studded.
