Lemon Curd Blondie Bars Recipe
Introduction
These Lemon Curd Blondie Bars are a delightful twist on traditional blondies, combining rich buttery sweetness with bright lemon flavor. Perfect for a sunny afternoon treat or a simple dessert to impress your guests.

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 (175°C). 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 and both sugars together until the mixture is light and fluffy.
- Step 3: Add the eggs one at a time, mixing well after each addition. Scrape down the sides of the bowl as needed to ensure even mixing.
- Step 4: Stir in the salt, baking powder, and lemon zest.
- Step 5: Add the lemon curd one tablespoon at a time, mixing until just combined after each addition.
- Step 6: Gradually add the flour, increasing the mixer speed and mixing until the batter is fully combined with no streaks remaining.
- Step 7: Press the batter evenly into the prepared baking pan. Lightly grease your hands if necessary to prevent sticking while smoothing the surface.
- Step 8: Bake for about 30 minutes, or until the edges turn just golden brown.
- Step 9: Allow the bars to cool completely in the pan on a wire rack. Use the parchment overhang to lift them out before cutting into 9 equal squares with a sharp knife.
Tips & Variations
- Use fresh lemon zest for the best vibrant flavor. You can also swirl additional lemon curd on top before baking for extra tang.
- If you prefer a denser texture, gently fold in 1/4 cup chopped white chocolate or macadamia nuts.
- For a gluten-free option, substitute all-purpose flour with a gluten-free baking blend of equal measure.
Storage
Store the bars in an airtight container at room temperature for up to 3 days. For longer freshness, keep them refrigerated for up to a week. To serve, bring to room temperature or warm briefly in the microwave for about 10 seconds.

FAQs
Can I make these bars ahead of time?
Yes, these bars hold up well when made a day in advance and stored properly. This also allows the flavors to meld beautifully.
Is lemon curd necessary for this recipe?
Lemon curd adds a unique zing and moistness to the blondies, but if unavailable, you can substitute with lemon jam or marmalade, though the texture and intensity of lemon flavor may vary.

Ingredients
Blondie Base
- 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 Curd
- 1/4 cup lemon curd
Instructions
- Preheat and prepare pan: Preheat the oven to 350°F (175°C). Line an 8×8 inch square baking pan with parchment paper, leaving overhang on all sides for easy removal later.
- Cream butter and sugars: In a large bowl or using a stand mixer, beat the softened butter together with granulated sugar and light brown sugar until light and fluffy, creating a smooth and aerated base for the blondies.
- Add eggs: Incorporate the eggs one at a time into the butter and sugar mixture, mixing well after each addition. Scrape down the bowl as needed to ensure even mixing.
- Mix dry ingredients and lemon zest: Add salt, baking powder, and lemon zest to the batter. Stir to combine evenly, enhancing the flavor with bright citrus notes.
- Incorporate lemon curd: Gradually add lemon curd one tablespoon at a time, mixing gently until just combined to maintain pockets of tart lemon flavor throughout the batter.
- Add flour: Increase mixer speed and gradually add the all-purpose flour, blending until no streaks remain and the batter is smooth but thick.
- Transfer and spread batter: Press the batter evenly into the prepared baking pan. To prevent sticking, lightly grease your hands if necessary while smoothing the top for uniform thickness.
- Bake: Bake in the preheated oven for approximately 30 minutes, or until the edges are golden and a toothpick inserted near the center comes out with moist crumbs but no wet batter.
- Cool and cut: Allow the blondies to cool completely in the pan on a wire rack. Using the parchment overhang, lift the bars out of the pan. With a sharp knife, cut into 9 equal square pieces.
- Store: Store the blondie bars in an airtight container at room temperature for up to 3 days, or refrigerate for longer freshness.
Notes
- For best results, use room temperature butter and eggs to ensure smooth mixing and proper texture.
- Do not overmix the batter once the flour is added to avoid tough blondies.
- Lemon curd can be homemade or store-bought; homemade lemon curd will enhance the fresh lemon flavor.
- If you prefer a stronger lemon taste, increase the lemon zest to zest of 2 lemons.
- These blondies are best served at room temperature but can be slightly warmed for a softer texture.
