How to Prepare Brown Butter Walnut Chocolate Chip Blondies

Ready to bring these blondies to life? Follow these simple steps:
Step 1: Brown the Butter
In a medium saucepan, melt the butter over medium heat. Continue to cook, stirring frequently, until the butter turns golden brown and has a nutty aroma. This should take about 5-7 minutes. Be careful not to burn it! Once browned, remove from heat and let it cool slightly.
Step 2: Mix the Wet Ingredients
In a mixing bowl, combine the brown sugar and the browned butter. Stir until well combined. Add the egg and mix until fully incorporated.
Step 3: Combine the Dry Ingredients
In another bowl, whisk together the flour, baking powder, and cinnamon. Make sure there are no lumps.
Step 4: Combine Wet and Dry Ingredients
Gradually add the dry ingredients to the wet mixture, stirring gently until just combined. Do not overmix!
Step 5: Fold in Chocolate and Walnuts
Gently fold in the chocolate chips (or chunks) and the toasted walnuts until evenly distributed throughout the batter.
Step 6: Bake the Blondies
Pour the batter into the prepared baking pan, spreading it evenly. Sprinkle the flaky sea salt on top. Bake in a preheated oven at 350°F (175°C) for 20-25 minutes, or until the edges are golden and a toothpick inserted comes out with a few moist crumbs.
Step 7: Cool and Slice
Once baked, remove the pan from the oven and allow it to cool on a wire rack. Once completely cooled, lift the blondies out using the parchment paper and slice them into squares or rectangles.
Dairy-Free/Gluten-Free Swaps

For those looking for alternatives, here are some easy swaps:
- Use vegan butter or coconut oil in place of unsalted butter for a dairy-free option.
- Substitute the all-purpose flour with a 1:1 gluten-free flour blend to make these blondies gluten-free.
Behind the Recipe
These Brown Butter Walnut Chocolate Chip Blondies draw inspiration from classic blondies but elevate them with the rich flavor of brown butter. The addition of walnuts not only adds a delightful crunch but also complements the sweetness of the chocolate and brown sugar. This recipe is perfect for sharing with friends or simply enjoying with a cup of coffee.
Best Ways to Store
To keep your blondies fresh and delicious:
- Store them in an airtight container at room temperature for up to 3-4 days.
- If you want to keep them longer, you can freeze the blondies. Wrap them tightly in plastic wrap and then place them in a freezer bag. They can be stored for up to 3 months.
- To thaw, simply take them out of the freezer and let them sit at room temperature for a couple of hours.
Handy Q&A
Can I use different nuts instead of walnuts?
Absolutely! Feel free to swap out walnuts for pecans, almonds, or even a mix of your favorite nuts. Just be sure to toast them for extra flavor.
What if I don’t have brown sugar?
You can make a substitute by combining granulated sugar with a little molasses. For every cup of granulated sugar, add about 1 tablespoon of molasses and mix well.
How do I know when the blondies are done baking?
The blondies are done when the edges are golden brown and a toothpick inserted into the center comes out with a few moist crumbs, but no wet batter.
Can I add other mix-ins?
Definitely! Feel free to get creative by adding dried fruit, coconut flakes, or even swirls of peanut butter for an extra layer of flavor.
