Chocolate Walnut Brownies

The full ingredients list and instructions are found in the printable recipe card at the end of this post. I highly recommend reading the blog post all the way through so that you don’t miss any tips or substitution suggestions and to ensure that you have all the ingredients and equipment required as well as understand the steps and timings involved.

Who doesn’t love brownies? I mean, they full of chocolatey flavor and taste so good! What’s not to love?

Now, if you add nuts to a brownie recipe, it provides not only a sweet and salty taste, it also adds a lovely texture to the chocolate dessert.

THEN if you add chocolate frosting on top and a sprinkling of nuts, then that makes these Chocolate Walnut Brownies out of this world awesome!

Brownies are really easy to make, and you need to make a pan of these as soon as possible!

You can make these brownies with or without the frosting, and if you want to switch the nuts to another type – pecans, hazelnuts, or almonds would all work so well.

This recipe uses American cups. They’re a handy piece of kitchen equipment to have along with a kitchen food scale. Having both in your kitchen means you’ll be able to make all of the different recipes on my blog as I use both cups and weighted measures.
