Tangy strawberry lemonade filling atop a buttery shortbread crust, ideal for warm-weather treats.

# 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, optional

# Step-by-step guide:

01 - Preheat oven to 350°F. Line an 8x8-inch baking pan with parchment paper, leaving 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 bottom of prepared pan, smoothing 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 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 crust from oven and pour strawberry lemonade filling evenly over hot crust.
07 - Return to oven and bake for 20 to 22 minutes until center is just set and no longer jiggles.
08 - Allow bars to cool completely in pan on rack, then refrigerate for at least 2 hours for clean slicing.
09 - Lift bars from pan using parchment overhang. Cut into 16 squares and dust with powdered sugar before serving if desired.

# Expert Advice:

01 -
  • The filling sets just enough to slice cleanly without being dense or rubbery, which took me three attempts to figure out.
  • Fresh lemon juice makes all the difference—the flavor brightness is something you'll notice immediately and remember.
  • These bars stay moist and delicious for days, making them perfect for meal prep or unexpected guests.
02 -
  • Don't skip the chilling time—I learned this the hard way when I tried to slice them warm and ended up with a filling-covered knife and a pan of mush.
  • If your strawberries are particularly juicy, the filling might take a few extra minutes to set; trust the jiggle test over the clock.
03 -
  • Use a sharp knife and wipe it clean between each cut, or dip it in hot water and wipe it dry—this gives you clean edges instead of ragged ones that squish the filling.
  • If you're serving these at a party, cut them just before serving rather than hours in advance; they dry out slightly if exposed to air for too long.
