Ingredients
Makes one 9×13-inch pan
- 2 cups gluten-free all-purpose flour blend (with xanthan gum included)
- 1/2 cup almond flour
- 3/4 cup powdered sugar (for crust)
- 1/2 teaspoon fine salt
- 12 tablespoons unsalted butter, cold and cubed
- 1 large egg
- 1 teaspoon pure vanilla extract
For the lemon raspberry filling:
- 1 1/2 cups granulated sugar
- 1/4 cup gluten-free all-purpose flour
- 4 large eggs
- 2/3 cup freshly squeezed lemon juice (about 3–4 lemons)
- Zest of 2 lemons
- 1 1/2 to 2 cups fresh or thawed raspberries
If you like a streusel topping, have an extra 1/2 cup cold butter, 3/4 cup gluten-free oats, and 1/2 cup brown sugar ready.
Step-by-step instructions
- Prep and preheat
- Preheat the oven to 350°F (175°C). Line a 9×13-inch pan with parchment paper, leaving an overhang for easy removal.
- Make the crust
- In a bowl, whisk 2 cups gluten-free flour, almond flour, powdered sugar, and salt. Cut in the cold cubed butter with a pastry cutter or your fingers until the mixture resembles coarse crumbs. Stir in the egg and vanilla until a soft dough forms.
- Press the dough evenly into the prepared pan. Bake for 15–18 minutes, or until the edges are lightly golden.
- Prepare the filling
- While crust bakes, whisk granulated sugar and 1/4 cup flour in a bowl. Add eggs, lemon juice, and zest; whisk until smooth.
- Add raspberries and bake
- Sprinkle raspberries evenly over the hot crust. Pour the lemon filling gently over the fruit. If using streusel, crumble it on top now.
- Return to the oven and bake 20–25 minutes, until the filling is set but still slightly jiggly in the center.
- Cool and chill
- Let the bars cool to room temperature, then refrigerate for at least 2 hours to fully set. Use the parchment overhang to lift from pan and cut into squares.
Tips for success
- Use room-temperature eggs for a smoother filling and better emulsification.
- If your gluten-free blend lacks xanthan gum, add 1/2 teaspoon for structure.
- Fresh raspberries give the best texture; if using frozen, do not thaw completely—toss briefly in a tablespoon of flour to prevent bleeding.
- For a perfectly even slice, chill the bars completely and wipe your knife clean between cuts.

Possible variations
- Streusel topping: Combine gluten-free oats, brown sugar, and cold butter to crumble on top before the second bake for a crunchy finish.
- Double raspberry: Swirl raspberry jam into the filling for an even fruitier bite.
- Almond twist: Replace almond flour in the crust with finely chopped pistachios for a nutty highlight.
- Other berry options: Swap raspberries for blackberries or strawberries for seasonal variety—see how strawberry bars come together in this alternate recipe: gluten-free strawberry bars.

Storage recommendations
- Room temperature: Keep in an airtight container for up to 24 hours.
- Refrigerator: Store covered for up to 5 days—best served chilled or at room temperature.
- Freezing: Cut bars and freeze in a single layer on a baking sheet, then transfer to a freezer bag for up to 3 months. Thaw overnight in the refrigerator.
- To refresh slightly soggy crust after refrigeration, let bars sit at room temperature for 30 minutes before serving.
Serving suggestions
- Dust with powdered sugar and serve with a dollop of whipped cream or a scoop of vanilla ice cream for a comforting dessert.
- Pair with hot tea or a milky latte for a cozy fall afternoon treat.

Frequently Asked Questions
Q: Can I make these bars dairy-free?
A: Yes. Replace the butter with a firm dairy-free butter alternative and use a plant-based substitute for whipped toppings. The texture will be slightly different but still delicious.
Q: Can I use frozen raspberries?
A: You can. Use frozen raspberries straight from the freezer, tossing them in a little flour to reduce bleeding, and expect a bit more moisture in the filling.
Q: How do I prevent the filling from cracking?
A: Avoid overbaking—the filling should be just set with a slight jiggle in the center when you remove it. Chilling helps it finish setting without cracking.
Q: Can I halve the recipe for a smaller pan?
A: Absolutely. Use an 8×8-inch pan for a smaller batch and reduce baking times slightly—watch the crust and filling closely for doneness.
