Ingredients
- 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
- 1/2 cup fresh raspberries or frozen, thawed
- 1/4 cup fresh lemon juice
- 1 tablespoon lemon zest
- 1/4 cup powdered sugar
Instructions
- Step 1: Preheat your oven to 350°F (175°C). Grease an 8×8-inch baking dish or line it with parchment paper for easy removal.
- Step 2: In a medium bowl, combine the flour, granulated sugar, and salt. Stir in the melted butter, egg, and vanilla extract until well combined.
- Step 3: Pour the mixture into the prepared baking dish and spread it evenly with a spatula.
- Step 4: In another bowl, mash the raspberries with a fork until slightly chunky. Stir in the lemon juice and lemon zest.
- Step 5: Drop spoonfuls of the raspberry mixture over the batter. Use a knife or toothpick to gently swirl the raspberry mixture into the batter, creating a marbled effect.
- Step 6: Bake for 25-30 minutes, or until the edges are golden and a toothpick inserted in the center comes out clean.
- Step 7: Let the bars cool in the pan for about 10 minutes. If using parchment paper, lift the bars out and cool completely on a wire rack. Dust the top with powdered sugar before cutting into squares.

- 1/4 teaspoon salt
Wet Ingredients
- 1/2 cup unsalted butter, melted
- 1 large egg
- 1 teaspoon vanilla extract
Fruit and Flavorings
- 1/2 cup fresh raspberries (or frozen, thawed)
- 1/4 cup fresh lemon juice
- 1 tablespoon lemon zest
Finishing
- 1/4 cup powdered sugar (for dusting)
Instructions
- 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.
- Mix the Base: In a medium bowl, combine all-purpose flour, granulated sugar, and salt. Stir these dry ingredients together. Then add the melted unsalted butter, large egg, and vanilla extract, mixing until a smooth batter forms.
- Spread the Mixture: Pour the batter into the prepared baking dish and use a spatula to spread it evenly across the bottom, creating a uniform base for the bars.
- Prepare the Raspberry Mixture: In a separate bowl, mash the fresh raspberries with a fork until slightly chunky. Stir in the fresh lemon juice and lemon zest to infuse the mixture with bright citrus flavor.
- Create the Swirl: Drop spoonfuls of the raspberry mixture over the batter. Using a knife or toothpick, gently swirl the raspberry mixture throughout the batter to create a marbled pattern.
- Bake to Perfection: Bake in the preheated oven for 25-30 minutes until the edges turn golden and a toothpick inserted in the center comes out clean. The aroma will be pleasantly citrusy and sweet.
- Cool and Dust: Remove from the oven and let the bars cool in the pan for about 10 minutes. If using parchment paper, carefully lift the bars out, then allow them to cool completely on a wire rack. Once cooled, dust with powdered sugar before slicing into squares and serving.
