The Best Frosted Dutch Cocoa Brownies
Decadent, rich, fudgy, and moreish, these are The Best Frosted Brownies I have ever had. Using Ghirardelli 100% Dutch-Processed Cocoa elevates these brownies to a whole new level, making them the perfect treat for any occasion. As a person who loves brownies and rarely turns my nose up at them, these stood out as a “wow brownie,” and I had to share this recipe with everyone.
I reconnected with a roommate from my first year of college. We now live in the same town after all these years, and we got together with our families. She brought these amazing brownies. I took one bite, and holy smokes! I thought, “These are so good! They are the type of dessert that makes your eyes roll back in your head on the first bite.
I asked her how she made them because I had to have the recipe. She told me they’re made with a special cocoa powder for the batter and the frosting, which makes them more rich than a typical brownie. Also, for the frosting, you use water instead of cream to thin it out, making them even more chocolately rich. I have never heard of using water in frosting before, but trust me, it works.
This recipe is for a 9×13 pan, but you can cut it in half. If your family is anything like mine, they will have no problem gobbling up a 9×13 pan of these indulgent brownies. You will make your kid’s day when they find this delicious brownie in their school lunch bag.

Frequently Asked Questions about How to Make The Best Frosted Dutch Cocoa Brownies
Can I use a different type of cocoa than Ghirardelli 100% Dutch-Processed Cocoa?
Dutch-processed cocoa has been treated with an alkalizing agent, which results in a smoother and richer flavor compared to natural cocoa powder. For the best deep and rich chocolate flavor, I recommend using Ghirardelli Dutch-Processed Cocoa or another brand of quality Dutch-processed cocoa. It is more expensive than natural cocoa powder, but it is totally worth it for this recipe.
Can I cut the recipe in half?
Absolutely. Use an 8×8 pan and bake the brownies for 40-45 minutes.
How can I tell when the brownies are done?
Insert a toothpick in the center, and if it comes out with a few moist crumbs, then the brownies are done.
Can I add chocolate chips or nuts?
Yes. Walnuts or pecans will add another delicious flavor and texture to the brownies. Adding semi-sweet chocolate chips will make these brownies supremely chocolately–a chocoholic’s dream.
How long should I let the brownies cool before frosting?
Let the brownies completely cool before frosting them.
