1 cup salted butter: Browning the butter builds that signature nutty flavor and enriching depth.
1¼ cup brown sugar (packed): Adds moistness and a rich molasses undertone that complements the butter.
½ cup granulated sugar: Provides balance and slight crispness around the edges.
2 eggs (plus 1 egg yolk): Ensure the blondies stay moist and help bind everything together.
2 teaspoons vanilla: Enhances the overall sweetness and adds warm aromatic notes.
2¼ cups all-purpose flour: The structure builder that keeps the blondies chewy but sturdy.
½ teaspoon baking powder: Gives a gentle lift to lighten the dense batter just enough.
1 teaspoon salt: Balances sweetness and deepens flavors.
1 cup white chocolate chips: Melt into pockets of creamy sweetness throughout every bite.

How to Make Brown Butter Blondies Recipe

Step 1: Brown the Butter

Start by melting the butter in a small pot over medium heat. Once melted, turn it down to medium low and stir occasionally. Watch as it simmers and gently browns, developing a warm golden color speckled with deeper brown flecks. The aroma will shift from buttery to nutty—this is your cue to take it off the heat. This step is crucial because it infuses the entire batch with that luscious, caramel-like richness distinct to brown butter.

Step 2: Cream Butter and Sugars

Next, pour your beautifully browned butter into a large bowl and beat it together with both the packed brown sugar and granulated sugar until the mix turns light and fluffy. This process helps dissolve the sugars and adds air, which gives your blondies a lighter texture instead of feeling heavy or dense.

Step 3: Add Eggs and Vanilla

Mix in the eggs plus the extra egg yolk along with the vanilla extract. This extra yolk adds an indulgent richness and contributes to the tender crumb that makes blondies so delightful. Blend well to ensure a smooth, uniform batter before moving on.

Step 4: Combine Dry Ingredients

In a separate bowl, whisk together the all-purpose flour, baking powder, and salt. Gradually incorporate these dry ingredients into your wet mixture. Stir just until combined—overmixing can make the blondies tough. Fold in the white chocolate chips gently so they stay intact and create bursts of sweet surprises.

Step 5: Bake to Perfection

Line a 9×13 inch baking pan with parchment paper for easy removal. Spread your batter evenly across the pan and pop it into a preheated 350˚F oven. Bake for 25 to 28 minutes until the blondies are set but still soft in the center. Let them cool for about 10 minutes before lifting them out of the pan and slicing into 24 irresistible squares.

Garnishes

While these blondies shine on their own, adding a sprinkle of flaky sea salt on top before baking enhances their caramel notes and creates a delightful contrast. For a festive touch, dust them lightly with powdered sugar or drizzle warmed white chocolate on top for extra indulgence.

Side Dishes

Pair your Brown Butter Blondies Recipe with a scoop of vanilla bean ice cream for a classic, crowd-pleasing dessert. Fresh berries or a cup of rich coffee also complement the buttery sweetness beautifully, balancing richness with bright or bitter notes.

Creative Ways to Present

For a fun dessert tray, serve blondies alongside an assortment of nuts, fruits, and homemade whipped cream. Cut them into bite-sized cubes and skewer with marshmallows and strawberries for a playful sweet-and-salty kabob. They also make delightful sandwich cookies when layered with your favorite frosting or ice cream.

Make Ahead and Storage

Storing Leftovers

You can keep your blondies fresh by storing them in an airtight container at room temperature. They stay moist and delicious for up to four days, making them perfect for prepping in advance for parties or snacks.

Freezing

If you want to save your Brown Butter Blondies Recipe for longer, slice them and freeze the pieces between sheets of parchment paper in an airtight container or freezer bag. They’ll keep well for up to three months. When you want one, just thaw at room temperature.

Reheating

Reheat individual blondie squares gently in the microwave for about 10-15 seconds or warm them briefly in the oven at 300˚F. This brings back that freshly baked softness and intensifies the butter flavor beautifully.

FAQs

Can I use unsalted butter instead of salted?

Yes, you can use unsalted butter but be sure to increase the salt slightly in the recipe to make up for the difference. Salt enhances flavor, so don’t skip it completely.

What makes brown butter different from regular melted butter?

Brown butter is heated longer until the milk solids caramelize and turn golden brown, resulting in a rich, nutty flavor and aroma that plain melted butter can’t match. It adds incredible depth to baked goods like these blondies.

Can I substitute nuts for the white chocolate chips?

Absolutely! Chopped pecans, walnuts, or macadamia nuts complement the brown butter flavor brilliantly if you prefer a crunchy texture over sweet pockets of chocolate.

How do I know when the blondies are done baking?

Look for edges that are set and lightly golden while the center looks just firm to the touch but still slightly soft. They will continue to firm up as they cool.

Can I make these blondies gluten-free?

Yes, swap the all-purpose flour for a gluten-free blend that measures cup-for-cup. The texture might be slightly different, but the flavor remains divine.
