  • Brown Butter. You can use salted or unsalted butter to make the brown butter for this recipe. For more tips and tricks – check out this post on How to Brown Butter. (Or make these classic blondies).
  • Granulated sugar. organic cane sugar and white sugar are great optios.
  • Light Brown sugar. If you like a deeper, molasses taste, use dark brown sugar.
  • All-purpose flour. For a gluten-free version, use an all-purpose gluten-free baking flour.
  • Fine Sea salt. If you use table salt (iodized) I recommend halving the salt.
  • Vanilla extract. This ingredient is key in this recipe. You could replace it with vanilla bean paste or the seeds of one vanilla bean, if necessary.
  • Mix-ins. You can choose your favorite mix-ins – or omit them because these browned butter blondies taste amazing without them. Suggestions include (but are not limited to): chocolate chips, white chocolate chips, dried fruit (cranberries, cherries etc.), nuts (pecans, walnuts), cinnamon chips, etc.

How to Make Brown Butter Blondies

We’ll walk through this recipe together, and don’t forget to watch the video.

Begin by preheating your oven to 350 degrees Fahrenheit (177 degrees Celsius) and preparing the baking pan. I suggest lining it with parchment paper for easy removal, but it’s not necessary if you want to serve them straight from the baking dish.

Then, brown the butter. For an in-depth post on how to brown butter click on the link. My greatest tip is to brown butter over medium-low heat in a thick-bottomed pan. Low and slow is key!

Then, transfer the browned butter to a glass mixing bowl to cool slightly.

While the brown butter is cooling, combine the flour, baking powder, and salt in a small bowl and set it aside.

Then, stir the brown sugar and granulated sugar into the cooled brown butter until combined.It’s important to make sure there aren’t any hard lumps of brown sugar left in the batter.

Then, add the eggs and vanilla to the butter/sugar mixture and stir until mixture is smooth.

Next, add the dry ingredients and stir until they are just combined, be careful not to over-mix the batter.

Fold in your preferred mix-ins until evenly distributed throughout the batter. Here are some mix-in suggestions:

  • Baking chips. white chocolate, semisweet chocolate, butterscotch chips, etc.
  • Nuts. pecans, walnuts, etc.
  • Chopped candy. you can chop up peanut butter cups, your favorite chocolate or candy bars and put them in the batter.

Then, spread the batter evenly in the prepared baking dish.

Bake for 22-25 minutes, or until the top is golden-brown and shiny (If you like fudgier brown butter blondies bake for 25 minutes, for cakier blondies bake for 30 I recommend 25).

Transfer the baking pan to a wire cooling rack and let the blondies cool in the pan for at least 30 minutes (preferably longer, they hold up better as they cool).

Once cooled, use the parchment paper to lift the browned butter blondies out of the pan, then cut into squares and serve

Serve

I enjoy serving these warm with a scoop of vanilla ice cream and a drizzle of caramel sauce or chocolate sauce.

Or, you can simply serve them room temperature or slightly warm. I personally love them a little warm even though they’re not as sturdy as when they’re cooled to room temperature.
