Last month, my coworker surprised us all by bringing a Kit Kat ice cream cake to the office potluck. The second I saw that wall of chocolate bars holding in layers of ice cream and fudge, I knew it was something my family would adore.
I asked her how she made it, but she just laughed and said, “Trial, error, and a freezer that never gets a break.” I couldn’t let it go, so on the weekend, I picked up the ingredients and gave it a go myself.
It turned out to be one of the most fun desserts I’ve ever put together. My kids stood by the counter, sneaking broken Kit Kat pieces and helping me press the candy bars around the crust like little chocolate fence posts. My husband, who usually just hovers around waiting to lick spoons, actually helped arrange M&M’s on top. It was one of those rare baking nights where nobody rushed off to their screens, the kitchen was the entertainment.
This cake looks extravagant but is surprisingly simple. There’s no need for fancy decorating skills or hours of prep. If you can crush cookies, spread ice cream, and line up Kit Kats, you can make this cake. And when it comes out of the freezer and you slice through those layers of fudge, candy, and ice cream, the payoff is priceless.
Short Description
This Kit Kat ice cream cake is a no-bake showstopper made with Oreo crust, layers of ice cream, fudge sauce, Kit Kats, and M&M’s. It’s colorful, festive, and perfect for birthdays, potlucks, or whenever you need an easy yet impressive dessert.
Key Ingredients
- 24 oz Oreo cookies
- 1 cup butter (2 sticks), melted
- 21 regular Kit Kat bars (whole, for outside of cake)
- 4 Kit Kat bars, chopped (for inside layers)
- ¾–1 cup chocolate fudge sauce (room temperature or refrigerated)
- 1 bag (10 oz) M&M’s
- 1 batch Kit Kat ice cream (or use store-bought vanilla)
- 1 batch Kit Kat chocolate ice cream (or use store-bought chocolate)
Tools Needed
- Food processor (for crushing cookies)
- 9-inch springform pan, lined with parchment
- Mixing bowl and spatula
- Sharp knife (run under hot water for slicing)
- Freezer space for chilling layers
Cooking Instructions
Step 1: Prepare the crust
Let ice cream soften at room temperature for about 10 minutes. Crush Oreos in a food processor until fine crumbs. Mix with melted butter until soft and moldable. Press into the bottom of the springform pan.
Step 2: Add the Kit Kat wall
Arrange whole Kit Kat bars vertically around the edges of the pan, logo facing outward. Gently press into the crust to hold them in place. Freeze 10 minutes.
Step 3: Layer with chocolate ice cream
Spread softened chocolate Kit Kat ice cream evenly over the crust. Smooth the top. Freeze for 2 hours until firm.
Step 4: Build the middle layers
Top the chocolate ice cream with a thin layer of fudge sauce, sprinkle on chopped Kit Kats, then spread softened vanilla Kit Kat ice cream on top. Freeze 2 hours.
Step 5: Finish with topping
Spread more fudge sauce over the surface, then cover with M&M’s. The fudge helps the candies stick. Freeze for at least 6 hours or overnight.
Step 6: Serve and enjoy
Before slicing, run a sharp knife under hot water for clean cuts. Serve straight from the freezer.
Troubleshooting tip: If your Kit Kats start slipping while arranging them, freeze the crust for 5 minutes before pressing the bars in place.

Mistakes to Avoid & Solutions
Using hard ice cream: If you don’t let the ice cream soften first, spreading will be frustrating. Solution: leave tubs out for 10–15 minutes.
Crust crumbling: If the Oreo mixture feels dry, add 1–2 extra tablespoons of melted butter.
Kit Kats falling over: Make sure the crust is pressed firmly and bars are snug against each other. Chill briefly before adding ice cream.
Rushed freezing: Cutting corners on freeze time leads to messy slices. Solution: always allow at least 2 hours between layers and 6 hours total.
Overloading toppings: Too many M&M’s can weigh down the top. Stick to a single even layer.

FAQs
1. Can I use store-bought ice cream?

2. Do I have to use Oreos for the crust?
No, you can use graham crackers, digestives, or any cookie you prefer.
3. Can I make this cake ahead of time?
Yes, it’s best when made the night before serving.
4. How do I slice it neatly?
Use a sharp knife dipped in hot water, wiping clean between cuts.

Line the base with parchment to prevent sticking.
For clean edges, freeze overnight before slicing.
