Buster Bar Ice Cake is a showstopping summer dessert that echoes a favorite ice cream treat but serves a crowd. Creamy vanilla ice cream is layered with crunchy graham crackers, rich hot fudge, and roasted peanuts, finished with that signature crackle of Magic Shell topping. If you want something nostalgic and utterly satisfying for your next gathering, this freezer cake always disappears fast at my house.
I put this together for my daughter’s birthday when it was just too hot to bake. It ended up stealing the show from the actual cake and now everyone asks for it every year.
Ingredients
- Chocolate graham crackers: Essential for that chocolaty crunch that lines the base. Choose whole crackers for strength and a store brand with good dark cocoa flavor
- Vanilla ice cream: Go for a rich, creamy style. Quality makes all the difference so pick a brand you would eat on its own
- Hot fudge sauce: Creates a decadent gooey layer. Use a high-cocoa variety and warm it a bit before spreading for easier layering
- Red skin peanuts: Bring a classic salty crunch to every bite. Seek out roasted and salted for balanced flavor
- Magic Shell chocolate coating: Delivers the iconic crackle and seals in the nutty layer. Store bought works beautifully if you want that signature snap
Instructions
- Soften the Ice Cream:
- Let the gallon of vanilla ice cream sit out on the counter just until soft enough to scoop easily. Ideally it should hold shape but be pliable when pressed with a spoon
- Prepare the Base:
- Arrange the chocolate graham crackers snugly across the bottom of a 9 by 13 inch baking dish. Break up a few crackers as needed so the entire base is covered edge to edge. This creates the structure for the whole dessert
- Layer the Ice Cream Bottom:
- Scoop half the softened ice cream onto the cracker layer. Use an ice cream scooper or a stiff spatula to gently smash and spread the ice cream into an even flat sheet. Press out air gaps as much as possible for a solid base
- Add the Fudge and Peanuts:
- Warm the hot fudge until pourable but not hot. Drizzle it across the ice cream and spread with an offset spatula or spoon into a thin even layer. Immediately scatter half the peanuts over the fudge, pressing down slightly to anchor them in place
- Layer the Ice Cream Top:
- Scoop the remaining ice cream over the peanuts and fudge. Spread it gently with a spatula all the way to the edges. Press until smooth creating a sealed ice cream top that holds everything in
- Add Final Peanuts and Magic Shell:
- Distribute the rest of the peanuts evenly over the ice cream. Drizzle the Magic Shell generously across the peanuts making sure to coat most of the surface. The shell will set up quickly locking everything together
- Freeze:
- Place the finished cake uncovered in the coldest part of your freezer for at least three hours or overnight for best texture. When ready to serve, cut into squares using a warm sharp knife for clean edges

Red skin peanuts are my favorite ingredient here because their saltiness and hint of earthiness play so well with the sweet fudge. I remember my aunt making a similar treat for every family summer reunion and to this day that crack of Magic Shell brings me right back to those noisy backyard tables.
Storage Tips
Cover leftover slices tightly with plastic wrap or store in a container with a firm lid for up to seven days in the freezer. Let sit at room temperature for a couple minutes before cutting to make slicing easier. Individual squares can be wrapped and stashed for single serve weekend treats.
Ingredient Substitutions
Try chocolate wafer cookies or regular graham crackers if chocolate graham crackers are not available. Swap in chocolate or coffee ice cream for vanilla for a richer flavor. Roasted cashews or almonds can stand in for peanuts if needed.
Serving Suggestions
Serve straight from the freezer with an extra drizzle of warm hot fudge. Top with whipped cream or a cherry for a sundae effect. Pairs beautifully with a hot espresso or strong coffee to balance the sweetness.
