What You Need for Tangy Lemon Raspberry Bars Recipe

How to Make Tangy Lemon Raspberry Bars Recipe
First, heat your oven to 350°F and line an 8×8 inch baking pan with parchment paper, leaving some overhang on the sides. This is your lifeline for getting the whole slab out later. Trust me.
Make the shortbread crust first. It bakes for a bit before you add the filling, which keeps it from getting soggy.
Step 1: Make the Shortbread Crust
Whisk the flour, sugar, and salt for the crust in a bowl. Cut in the cold butter with a pastry cutter or your fingers until the mixture looks like coarse crumbs. Press it firmly and evenly into the bottom of your prepared pan. Bake for 18 20 minutes, until the edges are just barely golden.
Step 2: Whisk the Lemon Filling
While the crust bakes, make the filling. In a large bowl, whisk the sugar and flour. Then whisk in the eggs, lemon juice, and lemon zest until everything is smooth and well combined. The mixture will be thin, that’s normal.
Step 3: Assemble and Bake
Once the crust is out of the oven, pour the lemon filling over the hot crust. It’s fine if the crust is still hot. Now, evenly scatter the raspberries over the top. They’ll sink a little, which is what you want. Bake for 30 35 minutes, until the filling is set and doesn’t jiggle in the center.
Step 4: Cool and Slice
This is the hardest part. Let the pan cool completely on a wire rack, then refrigerate for at least 2 hours. This sets the filling so you get clean cuts. Use the parchment paper to lift the whole bar out onto a cutting board. Dust with powdered sugar and slice into squares. It’s a great make ahead dessert, like a Moroccan chicken tagine, but for your sweet tooth.

Tips for Perfect Tangy Lemon Raspberry Bars
Get the Zest Right
Zest your lemons before you juice them. It’s infinitely easier. And only zest the bright yellow outer layer. The white pith underneath is bitter and will throw off your perfect tangy balance.
For Clean Slices
Wipe your knife clean between each cut. A little hot water helps too. It keeps the powdered sugar topping neat and prevents the gorgeous yellow filling from smearing everywhere. This same tip works for my blueberry lemon ricotta pancakes if you’re making a stack.

Frequently Asked Questions
Can I use bottled lemon juice?
I really don’t recommend it. Fresh lemon juice is essential for the bright, tangy flavor that makes these bars special. Bottled juice tastes flat and processed.
How do I store these bars?
Keep them in an airtight container in the fridge for up to 4 days. The powdered sugar will melt into the top, so you can dust them again right before serving.
Can I double this recipe?
Absolutely. Just double all the ingredients and bake it in a 9×13 inch pan. You may need to add a few extra minutes to the baking time for the filling to set.
I hope you love these bars as much as I do. They are my absolute favorite thing to bring to a picnic. Let me know how yours turn out.
Tangy Lemon Raspberry Bars
Ingredients
Method
- Preheat oven to 350°F (175°C). Line an 8x8 inch baking pan with parchment paper, leaving an overhang on two sides for easy removal. In a medium bowl, combine flour, sugar, and salt. Cut in the cold butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs. Press firmly and evenly into the bottom of the prepared pan. Bake for 15-18 minutes, or until lightly golden. Remove from oven and let cool slightly.
- While the crust bakes, whisk together the eggs and sugar in a large bowl until smooth and slightly thickened. Whisk in the fresh lemon juice and lemon zest. In a separate small bowl, whisk together the 1/4 cup flour and baking powder, then gently fold this into the wet egg mixture until just combined.
- Gently fold the 1 cup of fresh raspberries into the lemon filling. Pour the filling over the warm crust, spreading it evenly. Bake for 25-30 minutes, or until the filling is set and the edges are lightly golden. The center should have a slight jiggle.
- Place the pan on a wire rack and allow the bars to cool completely in the pan, about 1 hour. Then, refrigerate for at least 2 hours (or overnight) to fully set. This makes for clean cuts.
- Using the parchment paper overhang, lift the entire slab of bars out of the pan. Place on a cutting board. Using a sharp knife dipped in hot water and wiped dry between cuts, slice into 16 squares. Dust with powdered sugar if desired. Serve plain, or top individual bars with a dollop of whipped cream and a fresh raspberry.
