Equipment
Ingredients
- 1 cup unsalted butter
- ⅔ cup granulated sugar
- ⅔ cup light brown sugar, lightly packed
- 1 tbsp vanilla extract
- 2 tbsp bourbon
- 2 large eggs
- 2 ½ cups all-purpose flour, fluffed, spooned and leveled
- 1 ¼ tsp baking powder
- 1 tsp coarse Kosher salt (if using table salt, use half the amount)
- 1 cup chopped pecans
Instructions
- Preheat the oven to 350 F, and position a rack in the center of the oven. Lightly spray a 9x9 inch square baking pan with non-stick baking spray, or line it with parchment paper.
- In a saucepan, melt the butter over medium heat. Continue to cook the butter for about 4-5 minutes, swirling occasionally to see the bottom of the pan, until the butter is very fragrant, and nutty, golden brown solids have formed on the bottom of the pan.
- Pour the brown butter, scraping up all of the browned bits, too, into a medium-sized mixing bowl, and let cool at room temperature for 10 minutes.
- To the butter, add the granulated sugar, brown sugar, vanilla, bourbon, and eggs, and whisk vigorously for 2 minutes, until smooth and lightened in color.
- In a separate bowl, combine the flour, baking powder and salt. Add the flour mixture and the chopped pecans to the butter mixture, and stir together with a spatula until all the flour is incorporated.
- Spread the cookie dough evenly into the prepared pan. Bake for 30-35 minutes, until puffed and golden brown on top.Note: If you like your blondies more gooey and under-cooked in the middle, bake them for 30 minutes. In testing the recipe, 30 minutes was a bit too underdone for me, though, and I prefer the 35 minute bake.
- Cool the blondies completely, at least 4-6 hours, before cutting into 16 squares. If you want to serve them warm with ice cream, that's fine too, but they may not cut into neat squares while warm.
Notes
Store leftover blondies in an airtight container at room temperature for up to 3 days, or in the freezer for up to 3-6 months.
To make these without the bourbon, you can leave out the bourbon, and reduce the flour by 1 tablespoon.
