Strawberry Lemonade Bars (Printable Version)

Tangy strawberry lemonade filling on buttery shortbread crust for a refreshing, crowd-pleasing treat.

# What You'll 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, as needed

# How to Make It:

01 - Preheat oven to 350°F. Line an 8x8-inch baking pan with parchment paper, allowing overhang on sides 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 prepared pan, smoothing the surface. Bake for 18 to 20 minutes until lightly golden.
04 - While crust bakes, puree 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 partially baked crust from oven and pour strawberry lemonade filling evenly over the hot crust.
07 - Return to oven and bake for 20 to 22 minutes until the center is just set and no longer jiggles when gently shaken.
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 pan using parchment overhang. Cut into 16 equal squares and dust with powdered sugar before serving if desired.

# Expert Advice:

01 -
  • The tartness of real lemon juice cuts through the sweetness in a way that makes you want another slice immediately.
  • You can make them entirely by hand if you want—no fancy equipment required—yet they taste like you've been baking professionally.
  • They stay fresh in the fridge for days, making them perfect for when guests drop by unexpectedly.
02 -
  • Room temperature butter creams properly while cold butter will never reach that fluffy state, so plan ahead and leave your butter out for 30 minutes beforehand.
  • Freshly squeezed lemon juice is genuinely non-negotiable here—bottled juice tastes noticeably different and won't give you that bright, sharp flavor that makes these bars sing.
  • Those 2 hours of chilling are when the real magic happens; cutting them too early results in a filling that's still slightly loose and edges that crumble.
03 -
  • Invest in a microplane zester for your lemon zest—it creates fine, fluffy zest that distributes evenly rather than large pieces that taste bitter.
  • Keep your ingredients cool and work quickly when making shortbread; warm dough is much harder to press into an even layer, and you'll lose that delicate, tender texture.
  • If the filling cracks slightly on top after baking, don't worry—a dusting of powdered sugar hides any imperfections perfectly.
