Chocolate Walnut Brownies with Cocoa Powder

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:
Should brownies have walnuts?
In my humble opinion, yes! Brownies should have walnuts, or pecans, or almonds or any other kind of nut to add flavor and texture. In these chocolate fudge walnut brownies, the walnuts give you a soft, buttery crunch that goes so perfectly with the fudge brownies and pools of melted dark chocolate. If you really don't like walnuts, you can leave them out, but I just want to go on the record that I think that's a bad idea.
- 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 ⅔ 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.
Fudgy brownies are usually made with more cocoa powder, less flour, and more fat, like butter or oil. And to make sure 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.
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.
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!
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 9x9 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 9x9 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.
