Main Ingredients Notes

Ingredients measured t o bake brownies with frosting.

Semi-sweet chocolate chips – Use good quality chocolate chips, my go-to is Ghiradelli but you may have your own favorite. Melted chocolate in the brownie results in a fudgy chewy brownies.
Salted Butter -Most of us have salted butter this is why I used it for this recipe. You can substitute and use an equal amount of unsalted butter and add 1/4 teaspoon of salt to the recipe.
Regular Unsweetened Cocoa Powder – A classic Hershey Cocoa works just fine in this recipe. An option secret ingredient is adding a bit of espresso powder to the mix, it gives the brownies a bit of extra chocolatey yum.
Vanilla extract -Use pure vanilla extract or vanilla paste.

Mixing the Frosting RECIPE

What’s great about this creamy chocolate frosting is you make only what you need, and it compliments the fudge brownie recipe perfectly!

In a small bow mix together all the brownie frosting ingredients until smooth. The mixing is easier if you use a fork to break up any chunks in the powdered sugar when mixing with the, ( also called confectioners sugar )regular unsweetened cocoa powder, before adding to the icing mixture.
Once the brownies are cooled down begin frosting the top of the brownies. Use a rubber spatula or a small icing spreader. Viola! You just made a great brownie recipe!

Recipe Notes and Cooking Tips

Do not over-mix the batter. Over-mixing will result in tough brownies.

If you prefer a more cakey brownies, increase the baking time by 2-3 minutes.
