These blueberry lemon blondies are a sweet treat bursting with fruity goodness! The mix of fresh blueberries and zesty lemon creates a deliciously soft and chewy dessert.
Honestly, they smell amazing while baking, and you just can’t resist sneaking a warm piece! I love having these with a cup of tea—perfect for any cozy afternoon! ☕️
Key Ingredients & Substitutions
Unsalted Butter: Using unsalted butter allows you to control the salt in the recipe better. If you’re out of it, you can substitute with margarine or coconut oil, but butter gives the best flavor.
Brown Sugar: Light brown sugar adds moisture and a slight caramel flavor. If you have dark brown sugar, that works too! It’s even richer, but a mix of white sugar and molasses can be used in a pinch, too.
Eggs: Eggs help bind the ingredients and give structure. If you need a vegan substitution, try 1/4 cup applesauce or 1 tablespoon ground flaxseed mixed with 2.5 tablespoons water for each egg.
Lemon Juice and Zest: Fresh lemon regulates the melting sweetness of the blondies. If you don’t have fresh, bottled lemon juice can work, but it won’t be quite the same. Zest is also important for flavor, so don’t skip it!
Blueberries: Fresh blueberries are lovely, but feel free to use frozen ones if that’s what you have; just ensure they’re thawed and drained well. You can also try raspberries or chopped strawberries for a different twist!
How Do I Get the Perfect Texture in My Blondies?
Getting the right texture in blondies is key! A few important tips include:
- Mix the wet and dry ingredients until they’re just combined. Overmixing can lead to tough blondies.
- Be gentle when folding in the blueberries—this keeps the batter light and prevents berries from becoming mush.
- Don’t skip the cooling time! Let them cool completely in the pan for better slicing and texture.
Follow these steps, and you’re sure to get chewy, tender blondies every time!

How to Make Blueberry Lemon Blondies
Ingredients You’ll Need:
For the Blondies:
- 1 cup (2 sticks) unsalted butter, melted
- 1 ½ cups packed light brown sugar
- 2 large eggs
- 2 teaspoons vanilla extract
- Zest of 2 lemons
- 2 tablespoons fresh lemon juice
- 2 cups all-purpose flour
- 1 teaspoon baking powder
- ¼ teaspoon salt
- 1 ½ cups fresh blueberries (or frozen, thawed and drained)
For the Lemon Glaze:
- 1 cup powdered sugar
- 1-2 tablespoons fresh lemon juice
- Powdered sugar (for dusting, optional)
How Much Time Will You Need?
This recipe will take about 15 minutes to prep and 30-35 minutes to bake, for a total time of around 1 hour when you include cooling. This means you’ll have delicious blondies ready in just about an hour!
Step-by-Step Instructions:
1. Prepare Your Oven and Pan:
First, preheat your oven to 350°F (175°C). While that’s heating up, take a 9×9 inch baking pan and line it with parchment paper, allowing some excess to hang over the edges. This will help you lift out the blondies later.
2. Mix the Wet Ingredients:
In a large bowl, whisk together the melted butter and light brown sugar until the mixture is smooth. This is where the magic begins! Then, add the eggs one at a time, mixing well after each addition to ensure they’re combined nicely. Stir in the vanilla extract, lemon zest, and lemon juice, giving it a good mix until everything is well blended.
3. Combine the Dry Ingredients:
In another bowl, sift together the all-purpose flour, baking powder, and salt. Sifting helps to eliminate lumps and ensures a smoother batter.
4. Mix It All Together:
Slowly fold the dry ingredients into the wet mixture using a spatula. Mix until just combined—avoid overmixing to keep your blondies chewy!
5. Add the Blueberries:
Gently fold in the fresh blueberries. Take your time with this step, being careful not to smash the berries too much. They’ll give your blondies great bursts of flavor!
6. Bake the Blondies:
Spread the batter evenly into the prepared baking pan, smoothing the top. Place it in the oven and bake for 30-35 minutes. Keep an eye on them! They’re done when the edges are golden and a toothpick inserted in the center comes out clean or with a few moist crumbs.
7. Cooling Time:
Once baked, remove the blondies from the oven and let them cool in the pan on a wire rack. This cooling time is crucial, as it helps set them properly.
8. Prepare the Lemon Glaze:
While the blondies are cooling, make the lemon glaze. In a bowl, whisk together the powdered sugar and enough lemon juice to achieve a smooth and pourable consistency. Start with 1 tablespoon of lemon juice and add more if needed.
9. Drizzle and Serve:
Once the blondies are completely cool, drizzle the lemon glaze over the top. For an extra touch, you can dust them with a sprinkle of powdered sugar before cutting them into squares.
Enjoy your chewy, tangy blueberry lemon blondies with that delightful sweet glaze! Perfect for any occasion!
Can I Substitute the Eggs in This Recipe?
Yes! If you’re looking for an egg substitute, try using 1/4 cup unsweetened applesauce or 1 tablespoon ground flaxseed mixed with 2.5 tablespoons water for each egg. This will help maintain the texture and binding properties of the blondies.
How Can I Store Leftover Blondies?
To store leftovers, keep them in an airtight container at room temperature for up to 3 days. If you want to keep them longer, you can refrigerate them for about a week or freeze them for up to 3 months. Just wrap them tightly in plastic wrap or foil before freezing!
Can I Use Different Fruits Instead of Blueberries?
Absolutely! While blueberries pair wonderfully with lemon, you can substitute them with fresh or frozen raspberries, chopped strawberries, or even diced peaches for a refreshing change. Just be sure to adjust the sugar slightly if using sweeter fruits!
How Do I Get the Blondies to Rise Properly?
Ensure your baking powder is fresh for the best results. Gradually folding in the dry ingredients and avoiding overmixing is also crucial—this keeps the blondies light and chewy. Properly measuring the flour is important, so using a spoon to fluff it before scooping it into the measuring cup can help avoid dense blondies!
