Ingredients You’ll Need

Putting together this Blueberry Lemon Blondies Recipe is delightfully simple because it calls for everyday ingredients that each play an important role. From butter’s richness to blueberries’ juicy pop and lemon’s fresh brightness, every component comes together to create that irresistible flavor and texture combo.

Unsalted butter (1/2 cup, melted): Adds a buttery, moist base and depth of flavor without overpowering sweetness.
Brown sugar (1 cup, packed): Brings caramel notes and helps keep the blondies soft and chewy.
Large egg (1): Acts as a binder ensuring the blondies hold together with the right texture.
Lemon zest (1 tablespoon): Infuses a vibrant citrus aroma and tangy bite that brightens the whole dessert.
Lemon juice (1 tablespoon): Adds fresh acidity to balance the sweetness and enhance the blueberries.
Vanilla extract (1 teaspoon): Rounds out the flavors with warm, fragrant notes.
All-purpose flour (1 cup): Provides structure for a tender crumb that’s neither too cakey nor too dense.
Baking powder (1/2 teaspoon): Gives just enough lift for a light texture without making blondies fluffy.
Salt (1/4 teaspoon): Balances and enhances overall flavors, making every bite pop.
Fresh blueberries (1 cup): Adds juicy bursts of natural sweetness and eye-catching color throughout.
Powdered sugar (optional, for dusting): A pretty finishing touch that adds a delicate sweetness and visual appeal.

How to Make Blueberry Lemon Blondies Recipe

Step 1: Preheat the Oven

Start by preheating your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper to ensure your blondies come out cleanly and in perfect squares. This simple prep step saves cleanup time and maintains the blondies’ flawless texture.

Step 2: Mix Butter and Sugar

In a medium bowl, whisk together the melted unsalted butter and packed brown sugar until fully combined and smooth. This mix is the golden foundation that guarantees a rich and chewy texture in every bite.

Step 3: Add Wet Ingredients

Next, beat in the large egg, then fold in the bright lemon zest and fresh lemon juice along with the vanilla extract. Incorporating these now ensures your lemon flavor is distributed evenly throughout the batter, giving a refreshing tang that sets this recipe apart.

Step 4: Combine Dry Ingredients

In a separate bowl, whisk together the all-purpose flour, baking powder, and salt. Gently fold this dry mix into your wet mixture, being careful not to overwork it—this helps keep the blondies tender and slightly cakey without toughness.

Step 5: Fold in Blueberries

Now comes the star ingredient: fresh blueberries. Carefully fold them into the batter to avoid crushing, so each bite will include juicy bursts of berry goodness that balance perfectly with the lemon.

Step 6: Bake

Pour the batter evenly into your prepared baking pan and spread it out with a spatula. Bake in the preheated oven for 25-30 minutes, or until the edges are golden and a toothpick inserted comes out with a few moist crumbs. This baking time locks in moisture while giving a beautiful caramelized exterior.

Step 7: Cool and Serve

Allow your Blueberry Lemon Blondies to cool completely in the pan to firm up and make cutting easier. For an elegant touch, dust the top with powdered sugar before slicing into squares. These blondies are best enjoyed fresh but are just as tasty later on.

How to Serve Blueberry Lemon Blondies Recipe

Garnishes

To make your Blueberry Lemon Blondies Recipe even more irresistible, consider adding a light dusting of powdered sugar, a few fresh blueberries on top, or a small twist of lemon zest for extra color and zing. A dollop of whipped cream or a scoop of vanilla ice cream pairs wonderfully too.

Side Dishes

These blondies shine perfectly on their own but also complement fresh fruit salads, tangy yogurt parfaits, or a simple cup of tea or coffee. Their bright lemon notes provide a fresh balance to richer accompaniments, making them a versatile treat for any occasion.

Creative Ways to Present

For a fun twist, serve your blondies as mini bars on decorative plates or stack them in a dessert tower for parties. You can also cut into bite-sized squares and serve with colorful toothpicks for easy snacking. Wrapping each square in parchment paper tied with a ribbon makes a charming homemade gift.

Make Ahead and Storage

Storing Leftovers

Place leftover blondies in an airtight container at room temperature for up to 3 days. This keeps them moist and prevents them from drying out. If your kitchen is warm, storing them in the fridge is another option, though they might firm up slightly.

Freezing

Blueberry Lemon Blondies freeze beautifully. Wrap individual squares tightly in plastic wrap and place them in a freezer-safe bag or container. They can be frozen for up to 3 months without losing flavor or texture.

Reheating

To enjoy frozen blondies, simply thaw them at room temperature, or warm gently in a microwave for 15-20 seconds. Avoid overheating to keep their tender crumb and maintain the fresh lemon and blueberry flavors.

FAQs

Can I use frozen blueberries instead of fresh?

Frozen blueberries can work in a pinch, but fresh berries give a better texture and less watery batter. If using frozen, gently fold them in while still frozen to minimize color bleeding and moisture release.

What if I don’t have lemon zest? Can I substitute it?

If you don’t have lemon zest, finely grate the outer peel of the lemon very carefully, avoiding the bitter white pith. Alternatively, a small amount of lemon extract can be used but use sparingly since it’s more concentrated.

Will these blondies be too tart from the lemon?

Not at all! The lemon zest and juice add a fresh brightness that balances the sweet, buttery base and the blueberries’ natural sweetness. It’s a perfect harmony of flavors, not a sour punch.

Can I make this recipe gluten-free?

Yes! Substitute the all-purpose flour with a gluten-free flour blend of equal measure. Just make sure it’s a blend formulated for baked goods to ensure the right texture.

How do I know when the blondies are perfectly baked?

They’re ready when the edges turn golden brown and a toothpick inserted into the center comes out with a few moist crumbs but no wet batter. Overbaking can dry them out, so keep a close eye towards the end of baking time.
