I make this fudge brownies recipe with the Ghirardelli Double Chocolate Brownie mix, but I add different ingredients.
Honestly, Ghirardelli makes the BEST chocolate brownies and it is hard to beat them. Their double chocolate brownies have a fudge chocolate batter with chocolate chips that add a little crunch when cooled down.
You can use a different brownie mix, but if they don't turn out as good, I don't want to hear about it.... just saying!
I also add butter and buttermilk to make them off the chain.... It makes the brownies extra moist and gooey.
I take the brownies to a whole new level with my crackly fudge frosting. This is the stuff willy Wonka would have floating down that chocolate river. Friends, this stuff is ridiculous. Enjoy! Xoxo ~Katie.

Watch how to make
How do you make buttermilk?
If you do not have buttermilk at home handy, you can make your own. To make buttermilk, mix 1 cup of milk with 1 tablespoon of lemon juice or white vinegar.
Let the milk stand at room temperature 5 to 10 minutes until it thickens and forms small curdled bits.

Why add butter in place of oil?
Butter in brownie mix gives a fudgier texture than oil.

Is the frosting to be brought to a soft boil or to soft ball?
Katie Crenshaw says
Hi Cecille. The frosting needs to reach a soft boil.
