The BEST Cake Mix Mississippi Cookies

Mississippi Mud Cookies have always been a favorite of mine. There’s just something so irresistible about chocolate, marshmallow and walnuts piled high onto the same dessert. Well this summer I just had to make a fun and easy cake mix recipe fo get my fix and WOW did this recipe deliver! I had to take these to my neighbors right after I photographed them because I had already snuck 4! Whoops! They’re just sooooo tasty. The rich chocolate icing, fluffy marshmallow frosting, nuts and soft, brownie-like cookie. These are PERFECT for back to school baking! Plus, these keep in the refrigerator really well! So bake up a batch in the morning or the night before and your kiddos can have one after they get home from school.

Chocolate Marshmallow Cookies

You can make these Cake Mix Mississippi Mud Cookies with or without the walnuts. I am a huge nut fan but I know plenty of you out there would prefer them to be plain. If you want to really jazz these up, you can add sprinkles instead of nuts and they will look perfect for any party! Let’s talk more about this cake mix cookie recipe though because I do have a secret to making them perfect.

The Secret to Making THE BEST Cake Mix Cookies

My secret? It’s all about the brand of cake mix you use! I always, always, always use Pillsbury Devil’s Food Cake Mix for my cake mix cookies because they don’t flatten out! When I try using Betty Crocker or Duncan Hines they always bake super flat and then I’m stuck with sad looking cookies. Pillsbury cake mix always leaves my cookies nice and rounded. Sometimes they’re actually too tall so I gently press them flatter after baking with my fingers! You can see my Homemade Oreo recipe for more step by step photos for the baking process for these basic cake mix cookies.

How to make Mississippi Mud Cookies

After you bake up the cookies, let them cool and then top them with your marshmallow frosting. I like to use the marshmallow to leave a little raised edge around the outside so that when I spoon on my chocolate icing is stays in a pool in the middle! Before the chocolate icing sets, top the cookies with your nuts or sprinkles! Yum, these Cake Mix Mississippi Cookies are calling my name!

It’s back to school season, so that means cookies! I hope you give these Cake Mix Mississippi Mud Cookies a try this year, you’ll love them!
