- 2 and 1/2 tablespoons bourbon
- 1 teaspoon vanilla extract
- 1 large egg plus one egg yolk, at room temperature
- 1 cup all-purpose flour

How to Make Brown Butter Bourbon Pecan Chocolate Chunk Blondies
Step-by-Step Instructions
Step 1: Prepare Your Pan and Oven Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving some overhang for easy removal. Lightly grease the parchment paper with cooking spray or butter.
Step 2: Brown the Butter Place the butter in a light-colored saucepan over medium heat. Stir constantly as the butter melts, foams, and eventually turns a golden amber color with a nutty aroma. You’ll notice brown bits forming at the bottom – this is exactly what you want. Remove from heat and let cool for 5 minutes.
Step 3: Mix the Wet Ingredients In a large mixing bowl, whisk together the cooled brown butter and packed brown sugar until well combined. Add the bourbon and vanilla extract, mixing until smooth. Beat in the whole egg and egg yolk until the mixture is glossy and well incorporated.
Step 4: Add Dry Ingredients In a separate bowl, whisk together the flour, cinnamon, and salt. Gradually fold the dry ingredients into the wet mixture until just combined – don’t overmix.
Step 5: Fold in Mix-ins Gently fold in the toasted pecans and chocolate chunks, distributing them evenly throughout the batter.
Step 6: Bake Pour the batter into your prepared pan and spread it evenly. Sprinkle with flaky sea salt if desired. Bake for 22-25 minutes, or until the edges are set and the center is just slightly underdone – it will continue cooking as it cools.
Step 7: Cool and Serve Allow the blondies to cool completely in the pan before lifting them out using the parchment paper overhang. Cut into squares and serve.
Helpful Tips
Perfect Brown Butter Every Time: Use a light-colored saucepan so you can see the color change clearly. The butter will foam, subside, then start to brown. Don’t walk away during this process – it can go from perfect to burnt quickly.
Room Temperature Eggs: This ensures better incorporation and a smoother batter. If your eggs are cold, place them in a bowl of warm water for 10 minutes before using.
Don’t Overbake: These Ultimate Brown Butter Bourbon Pecan Chocolate Chunk Blondies should look slightly underdone in the center when you remove them from the oven. They’ll continue cooking from residual heat and will be perfectly chewy once cooled.
Toast Your Pecans: Toasting the pecans for 5-7 minutes in a 350°F oven enhances their flavor significantly and adds extra crunch to your blondies.

Difficulty: Easy
The key to these exceptional blondies lies in the brown butter technique. When butter is heated until it turns golden and develops a nutty aroma, it creates compound flavors that add incredible depth to baked goods. Combined with the warmth of bourbon and the richness of brown sugar, these flavors create a sophisticated dessert that’s perfect for entertaining or special occasions.
Notes

- Bourbon Substitution: If you prefer not to use alcohol, you can substitute the bourbon with an equal amount of vanilla extract or maple syrup for different flavor profiles.
- Chocolate Choices: Semi-sweet chocolate chunks work beautifully, but you can experiment with dark chocolate, milk chocolate, or even white chocolate depending on your preference.
- Pan Size Matters: Using an 8×8-inch pan creates the perfect thickness for these blondies. A 9×9-inch pan will make them thinner and may require slightly less baking time.
- Storage: These blondies actually improve in flavor after a day, as the bourbon notes mellow and blend with the other ingredients.
