Oreo Dirt Cake brings instant fun to any party table and is about as easy as it gets for a nostalgic kid-approved treat. A fluffy chocolate cake is covered with hot fudge, slathered with the creamiest chocolate pudding and Cool Whip topping, then scattered with those signature crumbled Oreos and wriggly gummy worms. It is a guaranteed hit for birthdays, potlucks, or just a random Tuesday when you want a reason to smile.
When I first made this for my nephew’s party, I had to shoo away all the grown-ups who insisted they needed an extra worm for good luck. This cake disappears so fast at gatherings it has become my “bring it or be in trouble” dessert.

Step-by-Step Instructions
- Bake the Cake:
- Prepare the chocolate cake according to the directions on the box using fresh eggs and oil for the softest crumb. Bake in a greased nine by thirteen inch pan at three hundred fifty degrees until a toothpick in the center comes out clean. Let the cake cool slightly but do not allow it to cool all the way before the next step.
- Poke and Fill:
- While the cake is warm use the rounded end of a wooden spoon to poke holes all over the top spacing them about half an inch apart. The holes should go most of the way to the bottom but avoid poking clean through so the fudge stays in.
- Pour Hot Fudge:
- Microwave the hot fudge sauce until pourable but not boiling. Pour it slowly over the entire surface focusing on getting some into every hole. Let sit while you make the pudding layer so the fudge soaks in deeply.
- Mix and Spread the Pudding Topping:
- In a big bowl whisk the half & half with the instant chocolate pudding mix until very smooth about two minutes. Let this mixture thicken for several minutes before folding in fully thawed Cool Whip. Spread the finished pudding mixture all over the cooled cake in an even layer.
- Finish with Oreo Crumbs and Gummy Worms:
- Pulse Oreos in a processor to create fine crumbs or smash in a sealed bag with a rolling pin. Sprinkle crumbs all over the pudding topping and gently press in gummy worms wherever you like. Refrigerate the cake for at least two hours to let everything set before cutting into squares.

My favorite part is that thick hot fudge middle layer which turns each bite into gooey magic. Last Easter my niece added extra “worms” to her piece then ceremoniously handed one to Grandpa who pretended it was real. Now it is a running family joke to “hide” an extra worm in someone’s serving.
Storage Tips
Wrap leftovers tightly or cover the pan before refrigerating to keep everything soft and the cookies crunchy. I find the flavor develops even more the second day. This is a great make-ahead dessert if you need to prep for a busy weekend.
Ingredient Substitutions
If you cannot find hot fudge sauce try using a thick chocolate syrup. No Cool Whip no problem just whip up one and a half cups of heavy cream with a little powdered sugar until soft peaks form. Any kind of chocolate cake mix will work including devil’s food or triple chocolate.
Serving Suggestions
Serve cold straight from the refrigerator in big squares. Oreo Dirt Cake is perfect for birthday parties school gatherings or backyard barbecues. For an extra touch I sometimes add sprinkles on top or tuck in little edible flowers for garden parties.

Cultural or Historical Context
This cake borrows from old-fashioned Southern poke cakes and adds a playful twist from classic Midwestern “dirt cake” desserts. Kids everywhere know the thrill of finding a “worm” in their slice and adults seem to get just as big a kick out of it.
