- Vanilla extract, 1 teaspoon: Adds warmth and depth to complement the lemon and blueberries.
- All-purpose flour, 1 cup: The foundation of the batter, providing structure and softness.

How to Make Blueberry Lemon Blondies Recipe
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper to ensure the blondies don’t stick and lift out easily once baked. This simple step ensures a clean release and perfect edges for slicing.
Step 2: Mix Butter and Sugar
In a mixing bowl, whisk together the melted unsalted butter and packed brown sugar until the mixture is smooth and glossy. This is where the classic blondie flavor begins, as the butter combines with the sugar to form a rich and luscious base.
Step 3: Add Wet Ingredients
Beat in the large egg, followed by the lemon zest, lemon juice, and vanilla extract. This combo brings vibrant citrus notes and fragrant vanilla that will make your kitchen smell heavenly. Mix everything thoroughly until smooth.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk together all-purpose flour, baking powder, and salt. Gradually fold this into your wet mixture to create a thick, velvety batter. Be gentle to avoid overmixing, which keeps the blondies tender and light.
Step 5: Fold in Blueberries
Carefully fold the fresh blueberries into the batter. Try not to crush them for a beautiful look and those delightful juicy bursts you crave. This step truly takes your Blueberry Lemon Blondies Recipe to the next level with natural fruit sweetness and texture.
Step 6: Bake
Spread the batter evenly into the prepared pan and bake for 25 to 30 minutes. The blondies should be golden and set around the edges but still soft in the center when done. A toothpick inserted in the middle should come out mostly clean with a few moist crumbs.
Step 7: Cool and Serve
Allow the blondies to cool completely in the pan so they firm up and are easier to slice. Dust with powdered sugar if you like a little extra sweetness and a fancy finish, then cut into nine generous squares. Now you’re ready to enjoy!
How to Serve Blueberry Lemon Blondies Recipe

Garnishes
A light dusting of powdered sugar is a classic and elegant choice to finish these blondies. You can also add a few extra fresh blueberries or thin lemon slices on the side for a pretty and fresh garnish that enhances every bite.
Side Dishes
Serve these blondies alongside a scoop of vanilla ice cream or a dollop of whipped cream for a truly indulgent dessert. For a lighter pairing, a simple bowl of fresh berries or a citrus fruit salad complements the lemon blueberry flavors beautifully.
Creative Ways to Present
These blondies shine beautifully broken into bite-sized pieces for a casual party platter, or stacked high on a dessert plate drizzled with honey or lemon glaze. You can also layer them with yogurt and fresh berries in parfait glasses for an elegant brunch treat.
Make Ahead and Storage
Storing Leftovers
Keep your Blueberry Lemon Blondies Recipe leftovers in an airtight container at room temperature for up to 3 days. This will preserve their moist texture and fresh flavor perfectly. If your kitchen is warm, consider refrigerating overnight to extend freshness.
Freezing
To freeze, wrap the cooled blondies tightly in plastic wrap, then place in a freezer-safe bag or container. They freeze wonderfully for up to 2 months. Thaw at room temperature when ready, then enjoy a slice of summer all year round.
Reheating
Warm slices gently in the microwave for 10 to 15 seconds to bring back that freshly baked tenderness and to soften the blueberries. You can also pop them into a low oven (around 300°F) for a few minutes to refresh their texture if you prefer.
FAQs
Can I use frozen blueberries in this Blueberry Lemon Blondies Recipe?
Yes, frozen blueberries can be a convenient alternative. Just be sure to thaw and drain them well before folding into the batter to avoid excess moisture, which can affect baking.
What if I don’t have fresh lemons for zest and juice?
If fresh lemons aren’t available, you can use bottled lemon juice and dried lemon zest as substitutes. For the zest, a small amount of lemon extract can also add brightness but use sparingly to avoid overpowering the batter.
Can I make these blondies gluten-free?
Absolutely! Substitute the all-purpose flour with a 1-to-1 gluten-free baking flour blend. Just keep in mind baking times may vary slightly, so keep an eye on the blondies as they bake.
How do I know when the blondies are done baking?
They are done when the edges are golden and pulling away from the pan, and a toothpick inserted near the center comes out with a few moist crumbs but no raw batter. The center should still feel soft but set.
Can I add other mix-ins besides blueberries?
Definitely! You can mix in white chocolate chips, chopped nuts, or even dried cranberries to complement the lemon flavor and add exciting textures. Just fold them in gently along with or instead of the blueberries.
Final Thoughts
Trying the Blueberry Lemon Blondies Recipe promises a delightful baking adventure that results in a treat you’ll want to make again and again.
