The sugar cookie mix pictured that I used contained 17.5 ounces. 2-1/2 cups was about half of the bag. You’ll need to measure the sugar cookie mix to get to the 2-1/2 cups – cookie and cake mixes have recently changed the ounces in their boxes/bags so be sure to use the measurement in the recipe instead of on the package.

I’m so sorry the fudge didn’t turn out the way you hoped. When fudge turns gritty, it usually means the sugar didn’t fully dissolve or it crystallized as it cooled. You can still try to make other treats from it! Here are a few ideas to help you salvage it and avoid tossing it out:

Warm it back up (I haven’t tested this): Try putting the fudge back in a saucepan with a splash of cream or evaporated milk, and heat gently while stirring constantly. This can help the sugar dissolve further. Once it’s smooth, pour it into a pan and let it reset.

Mix into cookie dough: crumble up the fudge and fold it into sugar cookie dough or even brownie batter. It’ll add little pockets of sweetness throughout!

I hope one of these ideas helps you enjoy your fudge in a new way. Thanks for giving the recipe a try.
