The tastiest Brown Butter White Chocolate Blondies. Homemade cookie-bars with white chocolate chips and browned butter for a truly gourmet experience. These soft and chewy blondies make the best treats!

Using brown butter in cookies is pure genius. My Brown Butter Toffee Cookies are also a favorite, and you should make that one next!

Best Blondies Recipe

After seeing how much ya’ll have been enjoying my Chocolate Chip Peanut Butter Blondies, I decided to share another favorite blondie recipe. A one-bowl, no chill recipe that’s enhanced with the nutty flavor of brown butter. You will soon be as obsessed with these like we are.

The other neat thing about this recipe is how adaptable it is. Instead of white chocolate chips as pictured, you can add your favorite mix-in ingredients.

• Add chocolate chips to the batter – or peanut butter, butterscotch, dark chocolate, or even toffee bits.
• Use chopped nuts in the dough – I recommend trying chopped pecans or walnuts.
• Decorate the tops with icing for the perfect birthday or holiday celebration.
• Leave them plain. You can simply skip the add-ins and all of the above options and enjoy them plain.

This is the perfect dessert for any time of year. Happy baking!

Ingredients needed for Brown Butter Blondies:

• Butter – You’ll need a 3/4 cup of unsalted butter. See above for how I brown the butter.
• Eggs – Two eggs, at room temperature.
• Sugar – A combo of light brown sugar and granulated sugar.
• Vanilla Extract – I love the Watkin’s Vanilla brand.
• Flour – You’ll need 2 1/4 cups of all-purpose flour.
• Salt – I use kosher salt.
• Baking Soda – The leavening agent for these blondies.
• Corn Starch – One teaspoon helps to make these treats soft inside.
• White Chocolate Chips – You’ll need one cup of white chocolate chips plus a few more for the tops.

How to make brown butter:

This process is very easy. You just have to be patient while browning, and watch it very closely. You want browned butter – NOT burnt butter.

1. Place butter in a pan on the stove, over medium heat.
2. Melt butter and when it begins to bubble, start stirring with a spatula. 
3. Keep the heat at medium, and stir gently, keeping the butter moving in the pan.
4. After about 6-7 minutes, you should see some browned bits starting to form on the bottom of the pan. When you see this, stir for a few seconds longer, and then remove the pan from the heat.
5. Pour the butter immediately into a bowl.
6. Let the butter cool slightly before using.
7. Now you are ready to use it in your blondies!

How to make White Chocolate Blondies:

Step 1
Brown the butter. (See above for complete instructions.)

Step 2
Combine wet ingredients. To a mixing bowl, combine the slightly cooled brown butter and both sugars. Use a hand mixer to cream together. Then add the egg and vanilla and mix again. 

Step 3
Add dry ingredients. Add the dry ingredients to the bowl – the flour, salt, baking soda, and corn starch. Mix until just combined.

Step 4
Add white chocolate chips. Add the white chocolate chips to the cookie dough and stir in to the dough with a spatula.

Step 5
Spoon dough in pan. Prepare an 8×8 pan with some parchment paper (makes it easier to lift the blondies out of the pan). Spoon the batter into the pan, evenly distributing it to all corners of the pan so that there is a smooth top. The batter will be thick.

NO Chill necessary. No need to chill the dough, but you can prep it in advance and chill if desired. I recommend chilling them IN the pan.

Step 6
Bake. Bake the blondies at 350 degrees for about 15 minutes, remove the pan, and carefully press extra white chocolate chips into the top and bake for another 8-12 minutes (or until done to your liking).

Step 7
Cool. Let the blondies sit in the pan for about 10 minutes after baking. Then carefully use the parchment paper (handles) to lift the blondies out of the pan. Place them on a wire rack. Slice.

Storing and Freezing

• STORE these chewy squares in an airtight container on your countertop for several days.
• FREEZE cookies in a cookie tin covered with a freezer bag. I prefer using disposable tins to store my cookies.
• You can also freeze the cookie dough and make them fresh any time you get a craving.

What does brown butter do for cookies?

Brown butter takes a regular cookie and makes it gourmet. It creates a nutty aroma and flavor profile that is like no other, especially in a cookie.

What happens when butter is browned?

When the butter melts, water evaporates out of the butter and the butterfat and milk solids separate. The solids sink to the bottom of the pan and eventually begin to brown. The butter then turns into a heavenly rich fat that will transform your cookies. Incredible flavor that is like no other.
