This homemade Buster Bar Ice Cream Cake captures everything I love about nostalgic summer treats: creamy layers of vanilla ice cream, gooey hot fudge, crunchy peanuts, and a chocolate shell all stacked over a crisp graham cracker crust. Inspired by Dairy Queen’s classic Buster Bar, this version is a no-bake wonder that is always the first dessert gone at birthday parties or family barbecues.
The very first time I made this, my grandma declared it more delicious than the original Buster Bar. It has become our go-to make-ahead summer dessert ever since.
Ingredients
- Fudge-covered graham crackers: These create a sturdy chocolatey base. Look for the ones with real chocolate and a crisp texture
- Vanilla ice cream: The star layer. Let it soften just enough to scoop and spread easily
- Hot fudge topping: Use high-quality hot fudge for a rich layer that holds its shape as it freezes
- Chocolate magic shell topping: This coats everything with that signature crack and glossy finish
- Dry-roasted peanuts: Choose unsalted or lightly salted. Fresh peanuts give maximum crunch and bring a salty balance to all the sweetness
Step-by-Step Instructions
- Prepare the Pan:
- Lightly spray a nine by thirteen inch baking pan with nonstick spray so the cake lifts out easily later
- Build the Graham Cracker Crust:
- Break the fudge covered graham crackers into smaller pieces and spread in an even layer across the bottom of the pan. Press down slightly to form a base
- Layer the First Ice Cream:
- Scoop one container of slightly softened vanilla ice cream on top of the crackers and spread it gently into a smooth even layer. Take your time to fill every corner
- Add Hot Fudge:
- Warm the hot fudge topping in the microwave for about ten to fifteen seconds so it is pourable but not hot. Pour evenly over the ice cream then gently spread with a spatula
- Sprinkle Peanuts:
- Scatter half a cup of dry roasted peanuts across the hot fudge to add a layer of salt and crunch
- Add Second Ice Cream Layer:
- Place the second container of softened vanilla ice cream over the peanuts and press into a flat layer with the back of a spatula
- More Peanuts:
- Sprinkle another half cup of peanuts evenly over the ice cream
- Finish with Magic Shell and Toppings:
- Warm both bottles of magic shell topping for eight to ten seconds and shake well. Pour over the entire top to cover. Quickly sprinkle remaining quarter cup of peanuts over the magic shell before it hardens
- Freeze:
- Cover the pan tightly with foil or a lid. Freeze for at least four hours until completely set and firm
- Serve:
- For clean slices, run a sharp knife under hot water and dry, then cut into twelve even pieces. Serve immediately for the best texture

When I was a kid, I looked forward to the chocolatey shell and crunchy peanuts on every bite. Now, tasting the first slice always brings up those summer memories of laughter and sticky faces.
Storage Tips
Keep any leftover cake tightly covered in the freezer to avoid frost bite and maintain freshness. The dessert will stay delicious for about ten days. If you are storing for longer, wrap the pieces individually in plastic and then store in a freezer safe container
Ingredient Substitutions
You can use any kind of ice cream that pairs well with chocolate and peanuts. Try chocolate chip or peanut butter for variety. For nut allergies, swap in crushed pretzels or caramel bits for texture. Chocolate wafer cookies also work great for the crust if fudge-covered grahams are hard to find
Serving Suggestions
Cut the cake into squares or rectangles for easy grabbing at parties. Serve each piece with a drizzle of extra hot fudge or a dollop of whipped cream. On extra hot days, I like to add a scoop of fresh berries for a refreshing tang
Cultural and Historical Context
The original Buster Bar has been a Dairy Queen favorite since the seventies known for its frozen layers on a stick. This cake adaptation gives you all the beloved flavors and textures in a shareable dish that feels just right for backyard gatherings and big family celebrations
