Key Ingredients for Lemon Blondies
Here’s a breakdown of the essential ingredients and their role in this recipe:
1. Fresh Lemons
- Purpose: The star of the recipe, providing zest and juice for a bright, tangy flavor.
- Tip: Always use fresh lemons for the best flavor. Bottled lemon juice won’t give the same vibrant taste.
2. Butter
- Purpose: Adds richness and creates the blondies’ fudgy texture.
- Tip: Use unsalted butter to control the salt level in the recipe.
3. Sugar
- Purpose: Sweetens the blondies and balances the tartness of the lemon.
- Substitution: Use granulated sugar for the batter and powdered sugar for the glaze.
4. Eggs
- Purpose: Provide structure and moisture, helping the blondies achieve their fudgy consistency.
- Substitution: For an egg-free version, use a flaxseed or chia egg substitute.
5. All-Purpose Flour
- Purpose: The base of the blondies, giving them structure.
- Substitution: For a gluten-free version, use a 1:1 gluten-free flour blend.
6. Vanilla Extract
- Purpose: Adds a warm, sweet undertone to enhance the lemon flavor.
- Tip: Use pure vanilla extract for the best taste.
7. Powdered Sugar (for the Glaze)
- Purpose: Creates a smooth, sweet glaze that complements the tangy lemon flavor.
Ingredients List
Here’s everything you’ll need to make these delightful lemon blondies:
For the Blondies:
- ½ cup (1 stick) unsalted butter, melted
- ¾ cup granulated sugar
- 2 large eggs
- 1 tablespoon lemon zest (about 1 lemon)
- 2 tablespoons fresh lemon juice
- 1 teaspoon vanilla extract
- 1 cup all-purpose flour
- ¼ teaspoon salt
For the Lemon Glaze:
- ¾ cup powdered sugar
- 1½ tablespoons fresh lemon juice
- ½ teaspoon lemon zest
Step-by-Step Instructions
Follow these expanded steps for foolproof, perfectly tangy lemon blondies:
1. Preheat and Prepare the Pan
- Preheat your oven to 350°F (175°C). Position your oven rack in the middle to ensure even baking.
- Line an 8×8-inch baking pan with parchment paper, allowing some overhang on the sides for easy removal of the blondies. If you don’t have parchment paper, grease the pan with butter or non-stick spray.
- Pro Tip: Lightly grease the parchment paper to prevent the blondies from sticking to the sides or bottom. This step ensures your blondies come out clean and intact.
2. Melt the Butter
- Melt ½ cup (1 stick) of unsalted butter in the microwave or on the stovetop. Allow the butter to cool slightly to avoid scrambling the eggs when mixing.
- Pro Tip: Melt the butter in a large microwave-safe mixing bowl to save on cleanup—you’ll use this bowl for the rest of the wet ingredients.
3. Mix the Wet Ingredients
- In the bowl with the melted butter, whisk in ¾ cup granulated sugar until smooth and creamy. The sugar should dissolve slightly, creating a glossy texture.
- Crack 2 large eggs into the mixture, one at a time, whisking well after each addition to ensure the batter is smooth and fully combined.
- Add 1 tablespoon of lemon zest (finely grated) and 2 tablespoons of fresh lemon juice. The zest will infuse the batter with a vibrant citrus flavor, while the juice provides a tangy kick.
- Stir in 1 teaspoon of vanilla extract, which adds a subtle sweetness and enhances the overall flavor.
4. Combine the Dry Ingredients
- In a separate bowl, whisk together 1 cup of all-purpose flour and ¼ teaspoon of salt.
- Gradually add the dry ingredients to the wet mixture, using a spatula or wooden spoon to gently fold them together. Mix just until no streaks of flour remain. Overmixing can lead to dense blondies.
- Pro Tip: For a lighter batter, sift the flour before adding it to the wet ingredients. This step prevents lumps and ensures even mixing.
5. Pour the Batter and Smooth It Out
- Pour the batter into the prepared baking pan, spreading it evenly with a spatula or the back of a spoon. Make sure to push the batter into the corners for a uniform thickness.
- Pro Tip: Tap the pan gently on the counter to release any air bubbles trapped in the batter.
6. Bake the Blondies
- Place the pan in the preheated oven and bake for 20-25 minutes.
- Start checking the blondies at the 20-minute mark. The edges should be lightly golden, and the center should look set but slightly soft.
- Insert a toothpick into the center—if it comes out with a few moist crumbs (but no wet batter), the blondies are done.
- Pro Tip: Avoid overbaking. Lemon blondies are meant to be slightly fudgy, so pull them out of the oven as soon as the center is set.
7. Cool Completely
- Allow the blondies to cool in the pan for about 10 minutes. Then use the parchment paper overhang to lift them out onto a wire rack to cool completely.
- Cooling is essential before adding the glaze—if the blondies are too warm, the glaze will melt and run off.
8. Prepare the Lemon Glaze
- In a small bowl, whisk together ¾ cup powdered sugar, 1½ tablespoons fresh lemon juice, and ½ teaspoon lemon zest. Adjust the glaze consistency by adding more powdered sugar for thickness or a few drops of lemon juice to thin it out.
- Pro Tip: Strain the lemon juice before adding it to the glaze to remove any pulp or seeds for a smooth texture.
9. Glaze the Blondies
- Once the blondies are completely cool, pour the glaze over the top and spread it evenly with a spoon or offset spatula. Allow the glaze to set for 15-20 minutes before slicing.
- For a decorative touch, sprinkle extra lemon zest or powdered sugar on top.
10. Slice and Serve
- Use a sharp knife to cut the blondies into squares or rectangles. Wipe the knife clean between cuts for neat edges. Serve and enjoy the zesty, fudgy goodness!
Tips for the Best Lemon Blondies
1. Use Fresh Lemons for Maximum Flavor
- Always use fresh lemons for both the juice and zest. The oils in fresh lemon zest add a vibrant and authentic citrus flavor that bottled juice can’t replicate.
- Pro Tip: Roll the lemon on the counter with your palm before juicing to release more juice.
2. Balance Sweetness and Tang
- The sweetness of the blondies perfectly complements the tangy lemon flavor. If you prefer a tarter dessert, increase the amount of lemon zest or juice slightly.
3. Don’t Overmix the Batter
- Overmixing can result in dense blondies. Stir the batter just until the dry and wet ingredients are combined.
4. Watch the Baking Time Closely
- Lemon blondies can go from perfect to overbaked quickly. Start checking for doneness a few minutes before the suggested baking time ends.
- Pro Tip: If the edges are browning too fast but the center isn’t done, lower the oven temperature by 10°F and cover the pan loosely with foil.
5. Customize the Glaze
- If you want a creamier glaze, add a tablespoon of softened cream cheese or a splash of heavy cream to the glaze mixture.
- For a creamier citrus dessert, check out Lemon Cream Cheese Pound Cake.
6. Chill for Perfect Slicing
- For neat, clean cuts, refrigerate the glazed blondies for about 20-30 minutes before slicing. This firms up both the blondies and the glaze, making them easier to handle.
7. Adjust for High Altitudes
- If baking at high altitude, reduce the sugar slightly (by 1-2 tablespoons) and increase the baking temperature by 10-15°F.
8. Store Properly
- Store leftover blondies in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to 1 week or freeze for up to 3 months.
- Pro Tip: Place parchment paper between layers of blondies when stacking to prevent sticking.
9. Add Textural Enhancements
- For extra crunch, fold in chopped nuts (like pecans or almonds) or white chocolate chips into the batter before baking.
10. Double the Recipe for Larger Crowds
- If you’re serving a large group, double the recipe and bake in a 9×13-inch pan. Increase the baking time to 25-30 minutes, checking for doneness regularly.
Variations for Lemon Blondies
1. Lemon Blueberry Blondies
- Fold in ½ cup of fresh or frozen blueberries to the batter for a fruity twist.
2. Gluten-Free Lemon Blondies
- Use a gluten-free flour blend instead of all-purpose flour for a gluten-free version.
3. Coconut Lemon Blondies
- Add ¼ cup of shredded coconut to the batter for a tropical flavor.
4. Lemon Poppy Seed Blondies
- Mix 1 tablespoon of poppy seeds into the batter for a fun, textured variation.
5. Extra Zesty Blondies
- Double the amount of lemon zest for an extra burst of citrus flavor.

How to Achieve the Perfect Texture
