This recipe is the jam. I have to say that all other blondies pale in comparison. We use it for our blondies at all of my bakeries. Also, learning to brown butter is an amazing tool to have in your culinary arsenal. You'll find it elevates a ton of dishes. —Duff

Makes one 9 x 13-inch pan

  • 3 sticks (1½ cups) butter
  • 3 cups lightly packed light brown sugar
  • 3 extra-large eggs
  • 1½ teaspoons pure vanilla extract
  • 3 cups all-purpose flour
  • 1 tablespoon baking powder
  • ½ teaspoon kosher salt
  1. First, brown the butter. Place it in a medium saucepan over low heat to cook. Check it after about 10 minutes; it should be a medium-brown color, not too light, not too burned. Once it reaches that color, take it off the heat and let it cool.
  2. Preheat the oven to 350˚F and grease a 9 x 13-inch pan.
  3. In a the bowl of a stand mixer fitted with the paddle attachment, beat the cooled brown butter and brown sugar until creamy. Add the eggs and vanilla and mix, scraping the sides of the bowl. Add the eggs and vanilla and mix, scraping the sides of the bowl. Add the flour, baking powder, and salt and mix until combined.
  4. Press the mixture evenly into the prepared pan.
  5. Bake the blondies for about 35 minutes, or until a toothpick inserted into the center comes out with only a few crumbs stuck to it. (I like these blondies gooey, so I go with a little less time). Let cool completely on a wire rack, then cut them and wrap them individually in plastic wrap so the sides don’t dry out. Store in the freezer or at room temperature.

Options: Add up to ¾ cup of your own ingredients, like pecans, chocolate chips, shredded coconut, butterscotch chips, peanut butter chips, or chopped dried cherries and white chocolate chips. Anything goes.
