Gear Up: What to Grab
Before you start baking, gather the following kitchen gear:
- Mixing bowl – for combining your ingredients

Step-by-Step: Brown Butter Walnut Chocolate Chip Blondies

Step 1: Brown the Butter
Start by browning the butter. In a small saucepan, melt the butter over medium heat, stirring frequently. Keep an eye on it as it foams and starts to turn a golden brown color. You’ll know it’s ready when it smells nutty and has a rich amber hue. Remove from heat and let it cool slightly.
Step 2: Mix the Wet Ingredients
In a mixing bowl, combine the warm brown butter and brown sugar. Whisk until smooth. Add in the egg and whisk until fully incorporated.
Step 3: Combine the Dry Ingredients
In another bowl, whisk together the flour, baking powder, and cinnamon. Gradually add this dry mixture to the wet ingredients, stirring gently until just combined. Be careful not to overmix!
Step 4: Fold in the Goodies
Gently fold in the chocolate chips and toasted walnuts. The mixture should be thick and rich.
Step 5: Bake
Preheat your oven to 350°F (175°C). Line your baking pan with parchment paper, leaving some overhang for easy lifting later. Spread the blondie batter evenly in the pan. Sprinkle flaky sea salt on top for that perfect contrast. Bake for 20-25 minutes, or until the edges are golden and a toothpick inserted into the center comes out with a few moist crumbs.
Step 6: Cool and Cut
Allow the blondies to cool in the pan for about 10 minutes before lifting them out using the parchment paper. Let them cool completely on a wire rack before cutting into squares.
Variations by Season

These Brown Butter Walnut Chocolate Chip Blondies are versatile and can be adapted for different seasons:
- Fall: Add 1/2 cup of chopped apples and a pinch of nutmeg for a cozy autumn twist.
- Winter: Incorporate crushed peppermint candies for a festive holiday flavor.
- Spring: Mix in some lemon zest and white chocolate chips for a refreshing touch.
- Summer: Throw in some dried cranberries or cherries for a burst of fruity flavor.
Pro Perspective
If you want to take these blondies to the next level, consider drizzling some melted chocolate on top once they’ve cooled. This not only enhances the chocolatey flavor but also makes for an impressive presentation. Additionally, if you’re a fan of gooey desserts, underbake them slightly for that ultimate chewy texture. Don’t forget to adjust the baking time based on your oven, as every oven can vary a bit.
Meal Prep & Storage Notes
These blondies are perfect for meal prep! You can store them in an airtight container at room temperature for up to a week. For longer storage, cut them into squares and wrap each individually in plastic wrap, then freeze. They’ll stay fresh for up to three months. Just thaw at room temperature or pop them in the microwave for a few seconds when you’re ready to indulge.
Your Questions, Answered
Can I use different nuts in this recipe?
Absolutely! Feel free to swap out the walnuts for pecans, almonds, or even hazelnuts for a different flavor profile.
What can I use instead of brown sugar?
You can use granulated sugar, but your blondies will be less chewy and may have a lighter flavor. If you want a similar taste, consider using coconut sugar.
Can I make these blondies gluten-free?
Yes! Substitute the all-purpose flour with a gluten-free flour blend that measures 1:1. Ensure your other ingredients are also gluten-free.
How do I know when the blondies are done baking?
Look for a golden brown edge and a slightly soft center. A toothpick inserted into the center should come out with a few moist crumbs, not wet batter.
