These white chocolate blondies are perfect for a barbecue or potluck too! It's an easy recipe, takes minimal time to prepare, and has simple ingredients. 

What is a Blondie?

I think of a blondie as a brownie without any of the regular chocolate or cocoa powder. They are the white chocolate version of a brownie. In other words, blonde brownies!

That means it still has a chewy texture, fudgy inside and that shiny crinkle top you find on chocolate brownies. If it's too cakey on the inside and the top is dull, then it's just a cookie bar and not a blondie. Just my opinion!

In this white chocolate blondie recipe, I've mixed in walnut and white chocolate chips to keep it more like classic blondies.

There are lots of recipes out there with various mix-ins, including dark chocolate chips! So feel free to change the add-ins to your blondie batter if you like but follow the process on the recipe card at the end of the post for the best results.

Full List of Ingredients for Making Blondies

Common Dry Ingredients: all purpose flour, salt, baking powder

Unsalted Butter: I always use unsalted butter so I can control the amount of salt. No need for room temperature butter this time because you will have to melt the butter. Some recipes use browned butter because it adds more depth to the flavor. I have skipped this to keep it simple but it is an option. 

Light Brown Sugar: Brown sugar gives these bars a deeper caramel and butterscotch flavor so do not substitute for white sugar. Dark brown sugar or some combination of light and dark is ok.

Large Eggs: Eggs hold everything together and also contribute to those shiny crackly tops on your blondies.

Vanilla Extract: Adds to the flavor. Be sure to use high quality extract and not imitation.

White Chocolate Chips: Use premium quality chips for the best taste. You can also chop up white chocolate bars for more chunky bits.

Walnuts: Nuts add so much texture to these bars. I recommend toasted walnuts. However, you can alter the amount to your taste or eliminate them without affecting the recipe. If I were to make these again, I'd probably add an extra half cup of walnuts.

How to Make Blondie Bars

Start by preparing a metal 9 x 13-inch pan. Brush it with butter and then line it with parchment paper, leaving an overhang on two opposite sides for easy release. If you only have a glass pan that's ok but the blondies will take longer than the noted time to bake. 

Many recipes call for creaming the butter and sugar together first. This is the method used for cookies and doing so here will give you a more cake like bar because creaming incorporates air into the batter.

To make it more brownie like, I used the same method as in my classic brownies recipe by melting the butter and sugar together instead of creaming.

Melt the butter in a medium saucepan over a low flame. Add the brown sugar and stir until it's mostly melted and incorporated. It's important not to overheat or bring to a boil! You just want the sugar to be melted. Then set the pan aside to cool. 

Combine the eggs, salt, baking powder, and vanilla and whisk until slightly pale. You will want to whisk it really well here because this action is what will contribute to those crackly tops! Use an electric hand mixer if you like. Stir in the melted butter mixture and mix well. 

Finally add the flour, white chocolate chips and toasted walnuts to the wet ingredients. Stir with a rubber spatula until just incorporated. Do not over mix this! Over mixing will lead to a cake like texture.

Pour the blondie batter into the prepared pan and bake at 350F for 25-23 minutes. The bake time is just a guide! I'd keep a watch after 20 minutes. You will want the top to be golden brown.

Test the inside by inserting a toothpick into the center. It should had a few wet crumbs on it. Nothing too gooey and no really dry crumbs. Let the blondies cool in the pan completely before cutting. 

To cut, loosen the edge of the blondies from the pan with a plastic knife (metal will scratch your pan) and lift the slab out of the pan using the parchment overhangs. Transfer to a cutting board and cut 24 even pieces. 

How to Store Blondies

Blondies can be stored in an airtight container at room temperature for up to 3 days. For long term freezer storage, wrap the blondies in plastic wrap and then place in an airtight container and freeze for  up to three months.

Ideas for Variations of Blondies

• Use chopped macadamia nuts instead of walnuts.
• Add peanut butter chips or butterscotch chips for a different flavor.
• Serve it warm with a scoop of vanilla ice cream for an extra delicious treat.
