Ingredients You’ll Need
- ½ cup (113 g) unsalted butter, melted: Adds a rich, creamy base and moisture to the blondies. For a lighter option, you can substitute half with unsweetened applesauce.
- ¾ cup (150 g) granulated sugar: Sweetens the blondies and helps create that lovely texture. Brown sugar can be used for a deeper flavor.
- 1 tsp (5 ml) vanilla extract: Enhances the overall flavor. Opt for high-quality pure vanilla for the best taste.
- 1 large egg, room temperature: Binds the ingredients together. Make sure it’s at room temperature to ensure smooth incorporation.
- 1 tbsp (6 g) lemon zest: Adds a burst of citrus flavor. Fresh is best; however, you can use bottled lemon extract in a pinch.
- 2 tbsps (30 ml) fresh lemon juice: Fresh juice infuses the blondies with that signature lemon taste. Bottled juice can substitute but may lack depth.
- 1 cup (120 g) all-purpose flour: The base ingredient for structure. For a gluten-free option, a 1:1 gluten-free baking flour can work well.
- ¼ tsp (1.5 g) table salt: Balances the sweetness. Don’t skip this; a small amount can elevate flavors.
- ½ cup (60 g) confectioners’ sugar: Used for the glaze. Cornstarch can be found in some all-purpose gluten-free flours if needed.
- 1-2 tbsps (15-30 ml) fresh lemon juice: Mixed with confectioners’ sugar to create a smooth glaze. Adjust the lemon juice to get the right consistency.
How to Make Lemon Blondies
Preheat the Oven: Set your oven to 350°F (177°C). Line an 8×8-inch (20×20 cm) baking pan with parchment paper, leaving an overhang on two sides for ease of removal later on. Lightly grease the parchment so the blondies won’t stick.
Mix the Wet Ingredients: In a medium mixing bowl, whisk together the ½ cup melted unsalted butter, ¾ cup granulated sugar, and 1 tsp vanilla extract until the mixture is smooth and creamy. Now, add in 1 large egg and whisk until it’s fully incorporated. Then, introduce the 1 tbsp lemon zest and 2 tbsps fresh lemon juice, mixing until everything is well combined.
Incorporate the Dry Ingredients: Gently fold in 1 cup all-purpose flour and ¼ tsp table salt with a spatula, taking care not to overmix. The batter will be thick, and it’s okay if you see a few dry streaks; just stir until they’re gone.
Spread the Batter: Transfer your batter into the prepared baking pan, spreading it evenly and smoothing out the top with an offset spatula or the back of a spoon to fill all corners.
Bake Until Golden: Place the pan in your preheated oven and bake for 20 to 22 minutes. You’ll know they’re ready when the edges are slightly golden and a toothpick inserted in the center comes out with moist crumbs. Be careful not to overbake; the blondies will continue to cook as they cool.
Cool Completely: Allow the blondies to sit in the pan until they are completely cool. This resting period is crucial; it helps firm up the structure, making them easier to glaze and slice later.
Make the Glaze: In a small bowl, whisk together ½ cup confectioners’ sugar and 1 tbsp fresh lemon juice until smooth and creamy. If the glaze is too thick, add more lemon juice, a little at a time, until you reach a pourable consistency.
Glaze the Blondies: Once the blondies are cool, drizzle the glaze evenly over the top. You can use a spoon to spread it gently if needed. Allow the glaze to set by letting them sit at room temperature for 20 to 30 minutes or pop them in the fridge for 10 to 15 minutes to speed things up.
Slice and Serve: Finally, lift the blondies out of the pan using the parchment overhang and slice them into 16 squares. Enjoy your luscious lemon blondies!

Storing & Reheating
You can store your lemon blondies at room temperature in an airtight container for up to 3 days. For longer freshness, place them in the refrigerator, where they can stay good for about a week. If you want to freeze them, wrap individual blondies in plastic wrap and then place them in a freezer-safe bag for up to 3 months. When you’re ready to enjoy them, simply thaw them at room temperature or microwave them briefly for about 10-15 seconds. Keep in mind that freezing can alter the texture slightly, but a quick reheat can bring back that soft, fudgy goodness.
Chef’s Helpful Tips
- Be careful not to overmix the batter after adding the flour; this can lead to drier blondies.
- Use room temperature ingredients, especially the egg, to ensure a smoother blend.
- Check for doneness with a toothpick to avoid overbaking; moist crumbs are ideal.
- Feel free to zest extra lemons for a stronger lemon flavor in both the blondies and the glaze.
- If making ahead, wait to glaze them until right before serving for the best presentation.
These lemon blondies are sure to become a cherished favorite, bursting with flavor and ease. Their refreshing taste paired with that soft, chewy texture will have everyone reaching for seconds (and thirds!). Experiment with different glazes or even add some blueberries for a fun kick. I can’t wait for you to enjoy these delectable squares of sunshine in every bite!
