Browned Butter

It’s a thing. Why brown the butter? Browning the butter adds a more nutty flavor to the dessert and gives it a deeper, sort of darker, flavor.

Blondie recipe bars are typically a lighter version of brownies and the browned butter makes it a fun and unique dessert.

What is brown butter?

Brown butter is the process of cooking unsalted butter long enough to allow it to turn brown. When browning butter, it cooks off the water that is in the butter and gives it a deep and rich flavor.

The process is also called beurre noisette and is used a lot for topping fish, pasta, and vegetables. And, you can add it to desserts, such as blondies, cookies, and cakes.

And, don’t be intimidated, it is an easy process.

How to brown butter

  1. Add the unsalted butter to a saucepan and turn the heat onto medium. Allow the butter to melt and keep stirring. You can turn the heat up to medium-high, but keep an eye on it so it doesn’t burn.
  2. Cook until the butter turns to a medium-brown color, stirring often.
  3. Pour the brown butter into a bowl and set aside for a few minutes.

The brown butter can be a light shade of brown, or go all the way up to a dark brown; however, the darker it gets the more bitter it will taste.

It’s a little hard to tell in this picture, but I cooked the butter and allowed it to get a little bit darker and then poured it into a large mixing bowl that I would be using.

What Ingredients Do I Need for the Brown Butter Blondie Recipe?

Full printable recipe with measurements and instructions listed at the bottom of the post.

  • Butter
  • Light brown sugar
  • Eggs
  • Vanilla extract
  • All-purpose flour
  • Baking powder
  • Salt
  • Toasted pecans
  • Chocolate chips

Toasting the pecans

Butter melting in a saucepan

Start by adding some butter to the saucepan and allowing it to melt.

Toasting pecans in a skillet

Next, add the chopped pecans to the saucepan and cook them for a few minutes until they are toasted. I cooked them for about five minutes on medium heat.

Once toasted, place the pecans in a small bowl and set to the side.

You will really be able to smell the pecans after a few minutes because the process of toasting brings out the wonderful nutty smell.

It reminds me of the Christmas song with chestnuts roasting on an open fire, but this time it’s pecans on a glass-top stove – ha! Still yummy, though.

How to Make the Easy Blondie Recipe

Brown sugar and butter in a glass bowl

Start by adding the brown sugar to the browned butter.

You can see the brown butter a little better in this picture below the sugar and it’s such a pretty amber-brown color.

Pour the vanilla extract into the bowl next.

Adding eggs to brown sugar and butter in a glass bowl

Add the eggs to the bowl and mix everything together.

Flour in a glass bowl with brown sugar and butter

Once you’ve mixed the ingredients, add the flour, baking powder, and salt to the bowl and mix again.

Next, add the toasted pecans to the batter.

Finally, add the chocolate chips to the batter and mix.

I like milk chocolate chips and thought it would add a sweeter taste, so that is what I added.

But, you can also use semi-sweet, peanut butter, or even white chocolate to the recipe for a different flavor.

Parchment paper in a casserole dish

Spray the 9″ x 13″ casserole dish with non-stick spray and place some parchment paper over the top. I go on and spray on top of the parchment paper again with non-stick spray.

Adding the parchment paper to the dish is not required, but will help when going to take the blondies out to cut them. Plus, it helps with clean-up and I am always happy about not having to scrub a dish.

If you don’t have parchment paper, never fear, just spray the dish with non-stick spray.

TIP: Having the casserole baking dish ready before you mix the ingredients is a good plan because the batter thickens fairly quickly, so it’s good to have it ready to spread.

Spraying the non-stick spray underneath the parchment paper just helps keep it in place.

I think I’ve just undone a year’s worth of diet management!! Amazing blondies! 12oz of chocolate chips is excessively decadent but so necessary!! The batter seems innocent until it starts to quickly firm up (thanks for the tip to have the pan prep’d ahead). Cooked for 25 minutes in a 9x9 metal pan instead of a 9x13 casserole to give them more height and I think it helped keep them more gooey. Sprinkled some flaked salt on top too for added interest and depth.
