These Chocolate Chip Walnut Blondies are everything you'd want from a blondie. They're perfectly golden, chewy and gooey beyond belief with a slightly crisp exterior, and loaded with melty chocolate chips and crunchy walnuts.
You can make these chocolate chip walnut blondies with ingredients you more than likely already have on hand.
- Butter: These blondies use melted butter similar to brownies for that gooey texture and crackled top.
- Dark brown sugar: Dark brown sugar has more molasses which means more chewy and fudgy blondie with rich flavor.
- Egg: One egg and one egg white makes for the perfect texture.
- Flour: All purpose flour.
- Vanilla: Reminiscent of a chocolate chip cookie and key for flavor.
- Salt: Kosher salt to balance it all out.
- Chocolate chips: Semi-sweet chocolate chips! I always prefer to bake with semi-sweet because they're just bitter enough and just sweet enough.
- Chopped Walnuts: Chocolate and walnuts is one of my favorite combos, and so is nuts in cookies - so this is a win win. Chopped walnuts are best so you get little pieces scattered throughout.
- Chocolate chips: You can use any of your favorite chocolate chips. If you prefer dark chocolate or milk chocolate or even white chocolate, use that! You can also substitute chocolate chunks instead of chips.
- Walnuts: You can sub your favorite nut if you don't like walnuts. Pecans, hazelnuts, almonds, etc.
- Dark brown sugar: Not ideal, but you can use regular brown sugar if it's what you have.
Difference between a blondie, cookie, brownie, and brookie
A blondie is a mix between a cookie and a brownie. The name evolved from "blonde brownie" into blondie!
It is a brownie that doesn't have cocoa.
It is a cookie that only uses brown sugar and is baked all together in a pan as opposed to individually. If cookies are more your thing try these oatmeal chocolate chip cookies.
A brookie is basically a brownie and a cookie combined - two separate batters.

Step by step instructions
These chocolate chip walnut bars come together in one bowl and take just a few minutes to prep, so it's very quick from start to devour.
- Whisk together butter and brown sugar.
- Whisk in the eggs and vanilla.
- Switch to a spoon or spatula and mix in the flour and salt.
- Fold in the chocolate chips and walnuts.
- Add to an 8x8 baking dish and smooth out.
- Bake 350℉ for 20-30 minutes until very light golden.
The detailed steps to make these blondies with chocolate chips and walnuts are truthfully not all that different from the quick overview! That's just how simple they are.
1. Combine butter and brown sugar. In a mixing bowl whisk together the melted butter and brown sugar until well combined.
2. Add the eggs and vanilla. To the bowl with the brown sugar butter mixture, whisk in the egg, egg yolk, and vanilla extract to complete the wet mixture.
3. Mix in the flour and salt. Switch to a spoon or spatula and mix the flour and salt into the wet mixture. Stop mixing when there are just a few streaks of flour left (we want to be careful to not over-mix).
4. Add the chocolate and walnuts. Fold the chocolate chips and chopped walnuts into the batter until everything is just combined.
5. Add to 8x8 pan. Spoon the batter into a well-greased 8x8 baking pan with parchment paper hanging over the edges. Flatten it out with your spoon so it's an even layer.
6. Bake. Bake at 350℉ for 20-30 minutes. They are done baking when the center is just set and looks light golden, and the edges are a more noticeable golden. Allow them to cool slightly in the baking pan, this will finish baking just enough.
Tips and tricks
While these chocolate chip walnut blondies are a breeze to make, below are some tips to help make sure they're perfect.
- Spoon and level the flour - do not scoop! You'll get way too much flour if you scoop and the blondies will be more cookie/cake-esque and not as gooey.
- Do not over mix the batter. You want to be sure to just mix the batter until everything is combined. If you over mix the batter it'll start working the gluten and you'll get a tougher more cake-like blondie. It's best to stop mixing the flour right before it's fully combined then add the nuts and chocolate chips to fully incorporate everything.
- It will be a thick batter. It's somewhere between a cookie dough and a brownie batter.
- Add more chips and nuts on top. Before you bake, if you want to really see what's inside the bars you can sprinkle additional chocolate chips and walnuts on top.
- Careful to not over bake! You want blondies to be gooey on the inside, and to achieve that you want them to be slightly underbaked when they come out of the oven because they'll finish off while they cool slightly in the pan. If you want them a bit more well done and cakey keep them in the oven for a few more minutes but keep an eye on them, they go from gooey to cakey very quickly.
- Serve with ice cream!! These are SO good when served right out of the oven with a big scoop of ice cream.
Store them in an air tight container at room temperature for up to 4 days. I like to reheat mine in the microwave for a few seconds so they're nice and warm.
Yes! Bake them, allow them to cool completely, wrap in aluminum foil and store in a freezer safe bag for up to 3 months. Warm in the microwave before eating!
Double the ingredients for the batter and bake it in a 9x13 baking pan for 25-35ish minutes. Keep an eye on it starting at 25 minutes - you want it to be lightly golden.
