Raspberry lemon bars always remind me of summer picnics and weekend baking sessions I would do with my kids The tart citrus and juicy berries combine with a rich buttery crust to create a treat that feels special but is surprisingly simple to make at home
I still remember the first time I pulled these gooey raspberry lemon bars out of the oven The scent had everyone running into the kitchen and now they are my most requested bake by friends and family alike
Ingredients
- All purpose flour: gives structure for the crust and filling Always measure with the spoon and level method for best texture
- Unsalted butter: provides rich flavor and a tender crumb Use very cold butter cut into cubes for flaky layers
- Powdered sugar: keeps the shortbread soft and just sweet enough Sift to prevent clumps
- Salt: balances flavor for crust and filling
- Vanilla extract: adds a comforting warmth to the base layer Use real extract if possible
- Granulated sugar: sweetens and also helps set the citrus filling Opt for superfine sugar if you want an ultra smooth custard
- Eggs: create a creamy texture and help the filling firm up Look for fresh large eggs for best results
- Lemon juice and zest: deliver that signature tang Select plump lemons and zest just the yellow layer for bright flavor
- Raspberries: bring color and juicy bursts throughout Use ripe berries with a strong scent for best taste
- Cornstarch: gently sets the filling without making it gummy Be sure to whisk it in thoroughly
- For garnish: powdered sugar adds a delicate finish while fresh raspberries and lemon slices make for a beautiful presentation
Step by Step Instructions
- Make the Shortbread Crust:
- Start by combining flour powdered sugar salt and the cubes of cold unsalted butter in a large mixing bowl Use a pastry cutter or clean fingertips to work the butter into the flour until it resembles coarse crumbs Drizzle in vanilla extract if using Mix until dough just comes together Press this evenly into the bottom of a parchment lined square baking pan making sure to reach the corners firmly Smooth the surface flat Bake at three hundred fifty degrees Fahrenheit for about twenty minutes or until lightly golden at the edges Remove and let cool slightly
- Prepare the Raspberry Lemon Filling:
- In a separate bowl whisk together the granulated sugar and eggs for about two minutes until very creamy and pale yellow Add lemon juice lemon zest mashed raspberries cornstarch and two tablespoons of flour Whisk well until the mixture is completely smooth and you see no streaks of flour
- Pour and Bake:
- Slowly pour the filling over the warm crust spreading it into an even layer Gently tap the pan on the counter to release air bubbles Return to the oven and bake for another twenty to twenty five minutes until the filling is just set in the center Do not overbake as the bars will firm up as they cool
- Cool and Garnish:
- Let the pan cool at room temperature for at least an hour For extra clean slices chill in the fridge for one to two hours Dust with powdered sugar and decorate with fresh raspberries and lemon slices just before serving

I love using Meyer lemons if I can find them because they add a gentle floral note One time my daughter decorated the entire tray with tiny edible flowers from our garden and it made dessert unforgettable
