Instructions
Brown the Butter
- Preheat your oven to 350°F (175°C) and line an 8x8-inch baking pan with parchment paper. Place the butter in a light-colored saucepan over medium heat. Stir constantly for 3-5 minutes until the butter turns golden amber and smells nutty. You'll see brown bits at the bottom – that's the magic! Remove from heat and let cool for 5 minutes.
Pro tip: The butter will continue cooking from residual heat, so don't let it get too dark in the pan.
Mix the Batter
- In a large bowl, whisk together the cooled brown butter and brown sugar until smooth. Add the egg and vanilla, whisking until combined. In a separate bowl, whisk together flour, salt, and baking powder. Add the dry ingredients to the wet ingredients, stirring just until combined. Don't overmix!
Add Mix-ins and Transfer
- Fold in any chocolate chips or nuts if using. Transfer the thick batter to your prepared pan, spreading evenly. For brown butter blondies with sea salt, sprinkle a pinch of flaky sea salt on top.
Bake and Cool
- Bake for 20-25 minutes, until edges are set and lightly golden but the center still looks slightly underdone. Don't overbake! Let them cool completely in the pan (about 2 hours) before cutting for the perfect chewy texture.

Expert Cooking Tips and Tricks
- Temperature Control: Keep your butter browning temperature at medium. Too high and the butter will burn before developing that nutty flavor.
- Visual Cues: Look for the butter to turn from yellow to golden amber. The foam will subside, and you'll see brown specks at the bottom of the pan.
- Texture Secrets: For extra fudgy blondies, slightly underbake them. For more cake-like bars, bake an additional 2-3 minutes.
- Mix-in Timing: Add chocolate chips or nuts after the batter is fully combined to prevent overmixing.
- Pan Size Matters: Using a different pan size will affect baking time. A 9x9 pan will result in thinner bars that bake faster.
Recipe Variations and Dietary Modifications
Brown Butter Pecan Blondies
- Add ¾ cup chopped toasted pecans for a classic Southern twist. Toast the pecans in a dry skillet for 3-4 minutes to intensify their flavor.
Brown Butter White Chocolate Blondies
- Fold in ½ cup white chocolate chips and a teaspoon of lemon zest for a bright, creamy variation.
Vegan Brown Butter Blondies
- Use vegan butter for browning (it works surprisingly well!) and substitute the egg with a flax egg. The texture will be slightly different but still delicious.
Keto-Friendly Version
- Replace the flour with almond flour and use a sugar substitute like erythritol in place of brown sugar. Reduce the amount slightly as sugar substitutes can be sweeter.
Small Batch Option
- Cut the recipe in half and bake in a 6-inch square pan for 15-18 minutes. Perfect when you want just a few bars!
Essential Equipment for Perfect Blondies
- Light-colored saucepan: Essential for seeing the butter brown properly. Dark pans make it difficult to judge the color.
- 8x8-inch baking pan: The perfect size for thick, chewy bars. Metal pans work best for even browning.
- Parchment paper: Makes removal and cutting so much easier. Don't skip this step!
- Wire whisk: Better than a spoon for incorporating ingredients smoothly.
- Rubber spatula: Perfect for folding in mix-ins without overworking the batter.
- Budget-friendly alternatives: If you don't have parchment paper, butter and flour the pan well. A wooden spoon can substitute for a whisk in a pinch.
