Strawberry Lemonade Bars Shortbread (Printable)

Tangy strawberry lemonade filling with a buttery shortbread crust for a refreshing, sweet treat.

# Required Ingredients:

→ 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

# Directions:

01 - Preheat oven to 350°F. Line an 8x8-inch baking pan with parchment paper, allowing edges to 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, smoothing the surface. Bake for 18 to 20 minutes, until lightly golden.
04 - While the 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 - Once the crust is baked, remove from oven and pour strawberry lemonade filling evenly over the hot crust.
07 - Return to oven and bake for 20 to 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 pan using parchment overhang. Cut into 16 squares and dust with powdered sugar before serving if desired.

# Expert Advice:

01 -
  • They're tangy and sweet at the same time, which somehow feels like eating sunshine on a plate.
  • The shortbread crust is so buttery it melts on your tongue before you even taste the filling.
  • These bars actually get better after a day or two in the fridge, making them perfect for batch cooking ahead.
02 -
  • Don't skip the pre-baking of the crust—this prevents a soggy bottom and gives you that structural integrity that makes these bars sliceable instead of crumbly.
  • Chilling for at least 2 hours is the real secret; hot bars will fall apart, but cold ones slice like butter and hold their shape on the plate.
  • Fresh lemon juice truly matters here because the filling relies on that bright acidity to balance the sweetness, and bottled juice is just not the same.
03 -
  • Press your crust firmly into the corners and edges of the pan so every bite has that buttery foundation, not just the center pieces.
  • Taste a strawberry before pureeing to gauge how sweet your filling will be; if they're tart, you've hit flavor gold, but if they're very sweet, consider pulling back slightly on the sugar in the filling.
  • Always use an 8x8-inch pan specifically; larger pans make thinner, more fragile bars, and smaller pans make them too dense and cakey.
