I am not sure what prompted me to make Nesquik brownies. My son bought it a while back, he enjoys Nesquick. I was first thinking hot chocolate brownies, then I saw the Nesquick sitting on the shelf and thought, why not. Sure enough, Pinterest comes through and there is a recipe. The Pinterest link can be found here.
Southern Made Simple blog post, but I did use only 1 cup of Nesquick and used 1/2 cup of baking cocoa.
I will likely try this recipe using Hot Chocolate. I will let you know how that turns out.
