Lemon Curd Blondie Bars Recipe
Introduction
These Lemon Curd Blondie Bars combine the rich, buttery sweetness of classic blondies with the bright, tangy flavor of fresh lemon curd. They’re a perfect balance of tender and zesty, making them a delightful treat for any occasion.

Ingredients
- 3/4 cup unsalted butter (softened)
- 1 cup granulated sugar
- 1/4 cup light brown sugar
- 2 large eggs
- 1/2 teaspoon salt
- 1/4 teaspoon baking powder
- Zest of 1 lemon
- 1/4 cup lemon curd
- 1 1/4 cups all-purpose flour
Instructions
- Step 1: Preheat your oven to 350°F and line an 8×8-inch baking pan with parchment paper, leaving an overhang on all sides for easy removal.
- Step 2: In a large bowl or stand mixer, beat the softened butter with both sugars until the mixture is light and fluffy. Add eggs one at a time, mixing well after each addition and scraping down the bowl as needed.
- Step 3: Stir in salt, baking powder, and lemon zest. Add the lemon curd gradually, one tablespoon at a time, mixing until just combined to maintain a lovely swirl effect.
- Step 4: Gradually incorporate the flour by increasing the mixer speed until the batter is fully combined with no flour streaks remaining.
- Step 5: Press the batter evenly into the prepared pan. Lightly grease your hands if the batter sticks to help smooth the surface.
- Step 6: Bake for about 30 minutes, or until the edges turn lightly golden. Allow the bars to cool completely in the pan placed on a wire rack.
- Step 7: Once cool, lift the bars out using the parchment overhang and cut into 9 equal squares with a sharp knife. Store in an airtight container to maintain freshness.
Tips & Variations
- Swap lemon zest with orange or lime zest for a different citrus twist.
- For a more intense lemon flavor, add a teaspoon of lemon juice to the batter along with the zest.
- Use homemade lemon curd if possible—it adds a fresh, vibrant flavor that store-bought options may lack.
- Try folding in white chocolate chips for extra sweetness and texture.
Storage

Ingredients
Blondie Batter
- 3/4 cup unsalted butter, softened
- 1 cup granulated sugar
- 1/4 cup light brown sugar
- 2 large eggs
- 1/2 teaspoon salt
- 1/4 teaspoon baking powder
- Zest of 1 lemon
- 1 1/4 cups all-purpose flour
Lemon Flavor
- 1/4 cup lemon curd
Instructions
- Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, making sure the paper hangs over all four sides to help lift the blondies easily after baking.
- Mix Butter and Sugars: In a large bowl or the bowl of a stand mixer, beat together the softened butter, granulated sugar, and light brown sugar until the mixture becomes light and fluffy. This will incorporate air and create a tender texture.
- Add Eggs and Flavorings: Add the eggs one at a time, mixing well after each addition to fully incorporate. Scrape down the sides of the bowl as needed. Then add salt, baking powder, and lemon zest, blending until combined.
- Incorporate Lemon Curd: Add lemon curd gradually, one tablespoon at a time, mixing just until combined. This ensures a uniform distribution of tangy lemon flavor without overmixing.
- Add Flour: Increase the mixer speed and add the all-purpose flour. Mix until the batter is fully combined with no visible streaks of flour remaining.
- Transfer and Smooth Batter: Press the batter evenly into the prepared baking pan. Lightly grease your hands if the batter is sticky to help you create a smooth, even layer.
- Bake: Bake in the preheated oven for approximately 30 minutes or until the edges are just golden and a toothpick inserted near the center comes out clean or with a few moist crumbs.
- Cool and Slice: Remove the pan from the oven and cool completely on a wire rack. Once cool, use the parchment paper overhang to lift the blondies out of the pan. Using a sharp knife, cut the slab into 9 equal pieces.
- Store: Store the bars in an airtight container at room temperature for up to 3 days or refrigerate for longer freshness.
Notes
- For even cleaner lemon flavor, use fresh lemon curd or homemade lemon curd if possible.
- If you prefer a more pronounced tang, swirl additional lemon curd on top before baking, taking care not to over mix.
- Ensure butter is softened but not melted for the best texture.
- To avoid overbaking, start checking for doneness at 25 minutes.
- These bars can be refrigerated for up to a week and warmed slightly before serving.
