What is the Difference Between a Brownie and a Blondie?

Blondies are frequently compared to brownies because their texture and consistency is so similar.

Brownies are all about the chocolate whereas blondies get their distinct butterscotch flavor from the combination of brown sugar, butter, vanilla and salt.

It’s basically a cookie bar that has the amazing richness and chewiness that brownies are known for.

Many people have a strong preference for either blondies or brownies. My husband, not surprisingly, is into blondies.

Blondies use a copious amount of butter – two full sticks. The butter provides a tremendous amount of flavor as well as contributes to the moistness that a good blondie recipe should exhibit.

I’m a stickler for quality ingredients, especially when it comes to baking. I used Challenge Unsalted Butter to ensure great flavor and quality in these epic blondies.

What You’ll Need For This Blondie Recipe

Blondies are made with typical baking ingredients that are most likely already in your pantry. As always, you can find the full printable recipe with complete instructions in the recipe card at the end of this post. Let’s take a look at what you’ll need:

unsalted butter – salted butter can be used instead, omit half a teaspoon of salt from the recipe.
brown sugar and granulated sugar
eggs – room temperature eggs incorporate better into the batter.
vanilla extract – use the good stuff for the best flavor.
all purpose flour – spooned and leveled for the most accurate measurement.
corn starch – makes them exceptionally chewy
baking powder – with all these rich ingredients, just a little leavener is needed.
salt – for balance and flavor.
chips of your choice – butterscotch, peanut butter, semi-sweet, or white chocolate chips

If you should so desire, top them with vanilla ice cream and butterscotch or caramel sauce for the most decadent, sinful treat imaginable.

How To Make Blondies

Preheat oven and lightly grease a 13 x 9 baking pan and line with parchment paper.

Combine melted butter and sugars. Stir well to combine.

Stir in eggs and vanilla extract.

Fold in flour, corn starch, baking powder and salt.

Stir in chips of your choice.

Transfer batter to the prepared baking dish and spread evenly.

Bake for 22 to 27 minutes.

Let cool completely before cutting into bars and serving.

Tips For The BEST Blondies

To make these blondies the best they can be, I used a few tricks that I have developed over the years for amazing results.

Make sure to pack your brown sugar when measuring. This will make sure your blondies have great flavor and the right amount of moistness.

Use REAL vanilla extract. I know that vanilla is insanely pricey right now due to a shortage of vanilla beans, but using real vanilla, if possible, produces the best flavor.

Corn starch. You’re not going to see this in a lot of blondie recipes but it deserves to be there. Just like in my favorite cookie recipes, corn starch makes these bars more tender and chewy.

I use an extra egg yolk just like in my favorite chocolate chip cookies recipe! I’ve been making cookies this way for almost a decade now and it makes SUCH a difference. Don’t leave it out!

Make sure you let your butter cool for 5 minutes or so after melting. That way you ensure you won’t run into any issues when you add the eggs. We’re making blondies, not scrambled eggs after all 🙂

I used white chocolate chips in this particular version but during my testing I tried every flavor of chip you can imagine and there wasn’t one that wasn’t spectacular. Use your favorite!
