Strawberry Lemonade Bars (Printable)

Tangy strawberry lemonade filling on buttery shortbread crust, perfect for spring and summer gatherings.

# What You Need:

→ Shortbread Crust

01 - 1 cup unsalted butter, softened
02 - 1/2 cup granulated sugar
03 - 2 cups all-purpose flour
04 - 1/4 teaspoon salt

→ Strawberry Lemonade Filling

05 - 1 cup fresh strawberries, hulled and diced
06 - 1 cup granulated sugar
07 - 3 large eggs
08 - 1/3 cup freshly squeezed lemon juice
09 - 1 tablespoon finely grated lemon zest
10 - 1/3 cup all-purpose flour
11 - 1/4 teaspoon salt

→ Topping

12 - Powdered sugar for dusting

# How to Make It:

01 - Preheat oven to 350°F. Line an 8x8-inch baking pan with parchment paper, leaving overhang for easy removal.
02 - In a medium bowl, cream together softened butter and sugar until light and fluffy. Add flour and salt, mixing until a soft dough forms.
03 - Press dough evenly into the bottom of the prepared pan and smooth the surface. Bake for 18-20 minutes until lightly golden.
04 - While the crust bakes, puree the diced strawberries in a blender or food processor until smooth. Strain through a fine mesh sieve to remove seeds if desired.
05 - In a large bowl, whisk together eggs, sugar, lemon juice, lemon zest, and strawberry puree until fully combined. Add flour and salt, whisking until smooth.
06 - Remove the baked crust from the oven and pour the strawberry lemonade filling evenly over the hot crust.
07 - Return to the oven and bake for 20-22 minutes, or until the center is just set and no longer jiggles.
08 - Allow bars to cool completely in the pan on a wire rack, then refrigerate for at least 2 hours for clean slicing.
09 - Lift bars from the pan using the parchment overhang. Cut into 16 squares and dust with powdered sugar before serving if desired.

# Expert Advice:

01 -
  • The filling has that custard-like texture that makes people think you spent hours in the kitchen when really you just mixed a few things together.
  • Strawberry and lemon are a pairing that never gets old, and the balance here is perfect without tasting cloying or overly tart.
  • They cut cleanly, look stunning on a plate, and taste just as good the next day, which makes them ideal for meal prep or unexpected guests.
02 -
  • Don't skip the pre-baking of the shortbread crust because a raw or underbaked crust will stay mushy no matter how long the filling bakes, and that transforms the whole eating experience from satisfying to disappointing.
  • The filling will look a little loose and wiggly when it comes out of the oven, but it firms up dramatically as it cools and chills, so don't panic or overbake it trying to make it look set.
  • Refrigerating for the full two hours isn't just about food safety, it's about getting those perfect clean cuts that make the bars look intentional and beautiful instead of rough around the edges.
03 -
  • Bring your eggs and butter to room temperature before you start because cold ingredients won't incorporate smoothly, and you'll end up with a filling that's slightly grainy instead of silky.
  • Use freshly squeezed lemon juice every single time because bottled juice tastes metallic and flat by comparison, and the couple of minutes it takes to squeeze two lemons is time well spent.
  • Cut the bars while they're still slightly cold from the fridge using a sharp knife and a damp towel between cuts, which gives you clean edges instead of crumbly, ragged squares.
