Cookies and Cream Fudge

Fudge doesn’t have to be intimidating, and this fudge recipe is no exception. Ever since a jar of marshmallow fluff had a Fantasy Fudge recipe on the container, I have added it to many of my other fudge recipes. Once you see how easy it can be to make, you will want to try as many flavors as possible! Give it as a Christmas gift, add it to your Christmas dessert charcuterie board, or serve it at your New Year’s Eve party.

Ingredients for Making Cookies and Cream Fudge in a Pan Before Stirring.

Ingredients & Substitutions

Heavy Cream: Look for heavy cream, also called heavy whipping cream, which is 36-40% fat.

White Chocolate Chips: High-quality chocolate chips are best for melting. You could also use a white chocolate baking bar, too.

Marshmallow Fluff: Marshmallow fluff, or marshmallow creme, is an ooey-gooey spreadable concoction that tastes like marshmallows. If you don’t have any on hand, make your own!

Oreo Cookies: It just makes sense to include Oreo cookies in the fudge, since they are a cookie and cream flavored sandwich cookie!

How to Harden Fudge

You have a few options when the fudge is ready to set. If you have the time (and the patience), you can let it set at room temperature, which will take a few hours. To speed up the process, you could chill the fudge in the refrigerator or even place it in the freezer for 30 minutes or so. But, when ready to serve, it’s best at room temperature.

How to Store

Fudge can be stored at room temperature in a sealed container for up to a week. For a longer shelf life, store it in the refrigerator for up to 2 weeks.

Can I Freeze Cookies and Cream Fudge?

Sure! If you are not going to enjoy the fudge within a week or two, freeze it! I like to separate the layers with parchment paper before storing the fudge in a freezer-safe container. Be sure to label and date the packaging; it will last up to 3 months. Let it thaw in the refrigerator when ready to enjoy.
