Ingredients You’ll Need

This Blueberry Lemon Blondies Recipe calls for simple, pantry-friendly ingredients that brilliantly blend to create its signature texture and flavor. Each ingredient plays a key role, from the richness of butter to the tang of fresh lemon, ensuring every bite is a perfect balance of sweet and zest.

Unsalted butter (1/2 cup, melted): Provides a rich, buttery base that keeps the blondies delightfully moist.
Brown sugar (1 cup, packed): Adds a deep caramel-like sweetness that complements the tartness of lemon and blueberries.
Large egg (1): Binds all ingredients together while adding structure and moisture.
Lemon zest (1 tablespoon): Packs a concentrated lemon flavor that brightens every bite without overpowering.
Lemon juice (1 tablespoon): Infuses a fresh, tangy quality that balances the sweetness perfectly.
Vanilla extract (1 teaspoon): Adds a warm, aromatic undertone that enhances the overall flavor.
All-purpose flour (1 cup): Forms the sturdy base of the blondies, giving them their tender, chewy texture.
Baking powder (1/2 teaspoon): Gives a subtle lift, ensuring the blondies are light rather than dense.
Salt (1/4 teaspoon): Amplifies the sweetness and balances flavors.
Fresh blueberries (1 cup): Bursts with juicy sweetness and adds a beautiful pop of color and freshness.
Powdered sugar (optional, for dusting): A delicate finish that adds a touch of elegance and extra sweetness.

How to Make Blueberry Lemon Blondies Recipe

Step 1: Prep Your Baking Pan

Start by preheating your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, which makes for easy removal of your blondies and a straightforward cleanup.

Step 2: Combine 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 step ensures that your blondies will have that signature chewy, fudgy texture.

Step 3: Add the Lemon and Egg

Next, stir in the egg along with the lemon zest, lemon juice, and vanilla extract. Mixing these wet ingredients well helps to evenly distribute the bright lemon flavor throughout the batter.

Step 4: Mix Dry Ingredients

In a separate bowl, whisk the all-purpose flour, baking powder, and salt. This helps to evenly incorporate the leavening agent and salt into the flour, so your blondies will bake uniformly.

Step 5: Combine Wet and Dry

Gently fold the dry ingredients into the wet mixture until just combined. Over-mixing can make the blondies tough, so take care to mix until you no longer see flour.

Step 6: Fold in the Blueberries

Carefully fold in the fresh blueberries, gently enough to avoid bursting them too much and turning your batter purple while ensuring they are evenly distributed.

Step 7: Bake to Perfection

Spread the batter evenly in your lined pan and pop it into the oven. Bake for 25 to 30 minutes or until the top is golden and a toothpick inserted near the center comes out mostly clean with only a few moist crumbs.

Step 8: Cool and Cut

Allow your blueberry lemon blondies to cool completely in the pan to firm up for easy slicing. Dust with powdered sugar if you like, then cut into squares and enjoy!

How to Serve Blueberry Lemon Blondies Recipe

Garnishes

A simple dusting of powdered sugar adds just the right touch of sweetness and visual appeal. For an extra pop, you can add a few fresh blueberries or a thin lemon slice on top of each blondie.

Side Dishes

These blondies pair wonderfully with a scoop of vanilla ice cream for a summer dessert or alongside a cup of hot tea or coffee for a cozy afternoon treat. If you’re feeling extra indulgent, a dollop of whipped cream with a sprinkle of lemon zest can be delightful.

Creative Ways to Present

Consider serving your Blueberry Lemon Blondies Recipe in mini muffin tins for individual portions at parties. Or, sandwich two smaller blondies together with lemon-infused cream cheese for a fun and unexpected dessert twist.

Make Ahead and Storage

Storing Leftovers

Store any leftover blondies in an airtight container at room temperature for up to 3 days. Their moist texture holds up well, making them just as delicious the next day.

Freezing

You can freeze the baked and cut blondies for up to 3 months. Wrap them tightly in plastic wrap and place them in a freezer-safe bag or container. Thaw overnight in the fridge before serving.

Reheating

To bring your blueberry lemon blondies back to life, warm them gently in the microwave for about 15 seconds or in a low oven (around 300°F) for 5-7 minutes. This revives their soft, chewy texture and melds the flavors beautifully.

FAQs

Can I use frozen blueberries instead of fresh?

Absolutely! Frozen blueberries work fine, but be sure to thaw and drain them well first to avoid excess moisture in your batter, which could affect the texture.

How do I know when the blondies are done baking?

Look for a golden top and edges pulling slightly away from the pan. Insert a toothpick near the center; it should come out with a few moist crumbs but no raw batter.

Can I substitute the lemon with another citrus fruit?

Yes! Lime or orange zest and juice can be used for a different citrus twist, but lemon’s tart brightness pairs especially well with blueberries in this recipe.

Is it possible to make this recipe gluten-free?

Definitely! Use a 1-to-1 gluten-free flour blend in place of all-purpose flour, and your Blueberry Lemon Blondies Recipe will be just as tasty and tender.

What’s the best way to prevent the blueberries from sinking?

Toss the blueberries lightly in a bit of flour before folding them into the batter. This helps suspend them evenly so they don’t all sink to the bottom.
