Ingredients

• 1 cup unsalted butter
• 2 cups packed light brown sugar
• 2 large eggs, room temperature
• 1 large egg yolk
• 2 teaspoons vanilla extract
• 2 cups all-purpose flour
• 1 teaspoon baking powder
• 1/2 teaspoon salt
• 1/4 teaspoon baking soda
• 1/2 teaspoon ground cinnamon, optional

How to Make Brown Butter Blondies

Step 1: Preheat the Oven

Preheat the oven to 350°F (175°C).

Line a 9×13-inch baking pan with parchment paper, leaving a little overhang on the sides for easy removal. Lightly grease the parchment.

Step 2: Brown the Butter

Place the butter in a light-colored saucepan over medium heat.

Allow it to melt completely, then continue cooking while stirring frequently.

The butter will foam and begin to develop golden-brown milk solids on the bottom of the pan. Once it smells nutty and turns amber, remove it from the heat immediately.

Pour the browned butter into a large mixing bowl and allow it to cool for about 10 minutes.

Step 3: Add the Brown Sugar

Add the packed brown sugar to the warm browned butter.

Whisk until smooth and well combined.

Step 4: Add the Eggs and Vanilla

Add the eggs and egg yolk one at a time, whisking well after each addition.

Stir in the vanilla extract.

The mixture should look thick, smooth, and glossy.

Step 5: Combine the Dry Ingredients

In a separate bowl, whisk together the flour, baking powder, salt, baking soda, and cinnamon if using.

Step 6: Make the Batter

Add the dry ingredients to the wet ingredients.

Fold gently with a spatula just until no dry flour remains.

Do not overmix, as overmixing can make the blondies more cake-like instead of chewy.

Step 7: Spread in the Pan

Transfer the batter to the prepared baking pan.

Spread it into an even layer, making sure the batter reaches the corners.

Step 8: Bake

Bake for 24 to 30 minutes, or until the top is golden and crackly and the edges are set.

A toothpick inserted near the center should come out with a few moist crumbs. Avoid baking until completely dry.

Step 9: Cool Completely

Place the pan on a wire rack and allow the blondies to cool completely before slicing.

The center will continue to set as it cools.

Step 10: Slice and Serve

Use the parchment paper to lift the blondies from the pan.

Cut into 16 large squares or 24 smaller bars.

Serve at room temperature.

Tips for Perfect Blondies

• Do not burn the butter: Remove it from the heat as soon as the milk solids turn golden brown and smell nutty.
• Pack the brown sugar: Brown sugar gives blondies their signature chewy texture and caramel flavor.
• Add an extra egg yolk: This helps create a richer, softer center.
• Do not overmix: Fold the flour in only until combined.
• Do not overbake: Slightly underbaked blondies stay much softer and chewier after cooling.
• Cool before cutting: Warm blondies are very soft and can fall apart when sliced too early.

Easy Variations

Chocolate Chip Blondies

Fold 1 cup of semi-sweet or milk chocolate chips into the batter before baking.

White Chocolate Blondies

Add 1 cup of white chocolate chips for a sweeter, creamier variation.

Pecan Blondies

Add 3/4 cup toasted chopped pecans for extra crunch and nutty flavor.

Salted Caramel Blondies

Drizzle thick caramel sauce over the batter before baking and finish the cooled bars with a small pinch of flaky sea salt.

Butterscotch Blondies

Fold 1 cup butterscotch chips into the batter for an even deeper caramel-style flavor.

Frequently Asked Questions

What is the difference between blondies and brownies?

Brownies usually get their dominant flavor from cocoa or chocolate, while blondies rely on brown sugar, butter, and vanilla for a caramel-like flavor.

Why brown the butter?

Browning butter cooks the milk solids until they become toasted and nutty, giving the blondies a much deeper flavor.

How do I know when blondies are done?

The edges should be set and the top should look golden and lightly crackled. A toothpick inserted near the center should have a few moist crumbs rather than coming out completely clean.

Why are my blondies dry?

Dry blondies are usually caused by overbaking or adding too much flour. Measure the flour carefully and begin checking the bars near the lower end of the baking time.

Can I add chocolate chips?

Yes. Semi-sweet, dark, milk, white chocolate, or butterscotch chips all work well.

Can I make these in a smaller pan?

Yes, but the blondies will be thicker and require additional baking time. Check frequently so the center stays soft and chewy.

Do blondies need to be refrigerated?

No. Plain blondies can be kept covered at room temperature for several days. Refrigeration can be used for longer storage.
