Ingredients

Scale

Base Batter

  • 1 cup all-purpose flour
  • 1/2 cup granulated sugar
  • 1/4 teaspoon salt
  • 1/2 cup unsalted butter, melted
  • 1 large egg
  • 1 teaspoon vanilla extract

Raspberry Lemon Swirl

  • 1/2 cup fresh raspberries (or frozen raspberries, thawed)
  • 1/4 cup fresh lemon juice
  • 1 tablespoon lemon zest

Topping

  • 1/4 cup powdered sugar, for dusting

Instructions

  1. Preheat and Prepare: Preheat your oven to 350°F (175°C). Grease an 8×8-inch baking dish or line it with parchment paper to ensure easy removal of the bars after baking.
  2. Mix the Base: In a medium bowl, whisk together the all-purpose flour, granulated sugar, and salt. Add the melted unsalted butter, large egg, and vanilla extract and stir until you form a smooth, combined batter.
  3. Spread the Mixture: Pour the batter into the prepared baking dish. Use a spatula to evenly spread the mixture, creating a flat and uniform base.
  4. Prepare the Raspberry Mixture: In a separate bowl, gently mash the fresh raspberries with a fork until they are slightly chunky. Stir in the fresh lemon juice and lemon zest to combine the flavors.
  5. Create the Swirl: Spoon dollops of the raspberry-lemon mixture over the batter. Using a knife or toothpick, gently swirl the mixture into the batter to create a beautiful marbled pattern.
  6. Bake to Perfection: Bake in the preheated oven for 25-30 minutes, or until the edges turn golden and a toothpick inserted in the center comes out clean. The aroma will be fragrant and inviting.
  7. Cool and Dust: Allow the bars to cool in the pan for about 10 minutes. If you lined with parchment, lift the whole slab out for easier handling. Transfer to a wire rack to cool completely. Before serving, dust the top with powdered sugar for a sweet finishing touch.

Notes

  • For an extra zing, add 1 teaspoon of lemon extract to the batter.
  • You can substitute blueberries for raspberries to change the flavor profile.
  • Enjoy the bars chilled for a refreshing dessert, especially on warm days.
  • Use room temperature ingredients for the best batter consistency.
  • Do not overmix the batter; a few lumps are okay for a tender crumb.
