I’ve been on a bit of a chocolate kick lately! Maybe it’s because of Valentine’s Day last week, but in the last few weeks I’ve shared my chocolate sour cream pound cake, my chocolate olive oil cake, my Keto chocolate mousse, and I’ve updated the recipe for my raspberry chocolate brownies! Well there’s no reason to stop now! These chocolate walnut brownies are the perfect way to continue all the chocolatey goodness of the past month.

These brownies are SO fudgy, and they’re filled with crunchy chopped walnut pieces and chocolate chunks. They’re a simplified version of my triple chocolate brownies recipe, with all the gooey, fudgy, chocolateyness you love about those brownies but in a more traditional, easy recipe! I grew up eating chocolate walnut brownies and I always loved how classic they were. They remind me of elementary school bake sales and after school Girls Scouts meetings. With this recipe, I hope you can capture some of that delicious nostalgia as well!

How do you make walnut brownies from scratch?

No need for that box mix! These chocolate walnut brownies are so simple to make and they’re even better than your favorite box mix! They’re fudgier with more chocolate chunks, and so irresistible! And the best part is that this is a simple, one-bowl recipe. You won’t need any special tools or techniques to make these chocolate walnut brownies! Let’s take a look at what you’ll need:

Classic Fudge Walnut Brownies Recipe - Better Than Box Mix! | Chenée Today


  • melted salted butter – I just popped mine into the microwave to melt so it was super easy! I like to use salted butter to ensure the most flavor in my baked goods. We’ll still add a bit of sea salt, so if you use unsalted butter just add a little extra salt.
  • eggs – make sure your eggs are room temperature to help them mix well into the other ingredients and allow the brownies to bake evenly.
  • vanilla extract – always grab a good-quality pure vanilla extract. Or better yet, check out my post on how to make vanilla extract at home with just 2 ingredients!
  • sea salt – this is to cut the sweetness a bit more and bring out those chocolatey flavors.
  • light brown sugar and granulated sugar – this combination of sugars adds the right amount of sweetness and chewy richness to these chocolate walnut brownies!
  • all-purpose flour – you’ll need 1 cup of flour for this recipe, measured out to 128 grams by weight or one cup using the spoon and level method.
  • unsweetened cocoa powder – this is what gives these chocolate walnut brownies their fudgy flavor and texture! I like the Ghirardelli Unsweetened Cocoa Powder, but use whatever variety you prefer.
  • chopped dark chocolate – I used a Ghirardelli Bittersweet Baking Bar, but you can use your favorite dark or bittersweet baking chocolate or chocolate chips! You’ll need about 2/3 cup of chocolate.
  • chopped walnuts – you can either buy a bag of chopped walnuts or chop up your own whole walnut halves. Feel free to add more or fewer walnuts according to your preference!


This chocolate walnut brownies recipe is so simple! You won’t need any specialized tools to make it, but here are a few tools I’d recommend:

Tips and F.A.Q.

What makes brownies fudgy vs cakey?

Fudgy brownies are usually made with more cocoa powder, less flour, and more fat, like butter or oil. And to make sur9e you get that fudgy, gooey texture you want for these chocolate walnut brownies, check your brownies a little before the baking time is up! For gooey brownies, take them out when the center is just set and no longer jiggles.stacked chocolate walnut brownies

What are they best nuts for brownies?

Any nuts you like! I love brownies with pecans like in my triple chocolate brownies, and macadamia nuts and hazelnuts would be lovely too! For these chocolate walnut brownies, we’re going with chopped walnuts. I like to just grab a bag of store-bought chopped walnuts from the baking aisle, but you can also use whole shelled walnuts and chop them yourself.

Should you toast walnuts before baking?

Actually, no — the high fat content in walnuts means they toast much faster when baking, so if you toast them beforehand they may burn. This is great for this chocolate walnut brownies recipe, because it saves us a step! Just toss the raw walnuts into your brownie batter!

Can I freeze these chocolate walnut brownies?

Absolutely! First you’ll want to let your brownies cool completely. If they’ve already been cut into individual brownies, then wrap each one in plastic wrap and place in the freezer to freeze solid. Once they’re frozen, place them in a freezer bag for up to two months. If they haven’t been cut yet, then wrap the entire 9×9 block of brownies in plastic wrap and then in aluminum foil. You can also place it in a gallon-size freezer bag — if you baked your brownies in a 9×9 pan, it should fit. Again, they should stay fresh in the freezer for up to two months. Let them thaw, still wrapped, at room temperature before serving.
