Ingredients You’ll Need
To make this luscious frozen cake, gather the following:
- 14 fudge graham crackers, crushed – These form a sweet, chocolatey base.
- 96 oz vanilla ice cream, softened – That’s about 3 standard tubs of ice cream.
- 16 oz hot fudge topping, slightly warmed – For that rich, decadent middle layer.
- 14.5 oz chocolate magic shell topping – This hardens on top just like DQ’s iconic chocolate coating.
- 1¼ cups dry roasted peanuts, roughly chopped – Adds crunch, saltiness, and nostalgia.
Step-by-Step Instructions
Step 1: Prepare the Crust
Start by crushing your fudge graham crackers into fine crumbs. You can use a food processor or place them in a zip-top bag and crush them with a rolling pin. Press the crumbs firmly into the bottom of a 9×13-inch baking dish lined with parchment paper. This will serve as your chocolatey crust. Place the dish in the freezer to chill while you prepare the next layers.
Step 2: Add the First Ice Cream Layer
Let your vanilla ice cream sit at room temperature for 10–15 minutes to soften slightly. Once scoopable, spread half of the ice cream evenly over the chilled crust. Smooth it out with a spatula. Place the dish back in the freezer for at least 30 minutes to firm up.
Step 3: Layer on the Fudge and Peanuts
After the first ice cream layer is firm, drizzle the warm hot fudge topping evenly across the surface. Try to cover every inch for maximum richness. Immediately sprinkle the chopped peanuts over the fudge while it’s still warm and gooey — they’ll stick better this way and create a delicious salty-sweet layer.
Step 4: Add the Second Ice Cream Layer
Spread the remaining half of the vanilla ice cream over the fudge and peanut layer. Work quickly so the ice cream doesn’t melt. Smooth the top with a spatula and return the dish to the freezer for at least 1 hour, or until very firm.
Step 5: Finish with Magic Shell
Once the top ice cream layer is frozen solid, pour the magic shell chocolate topping over the entire surface. Tilt the pan gently if needed to ensure full coverage. As the chocolate hits the cold surface, it will instantly harden, forming that signature crispy shell that makes Buster Bars so irresistible.
Freezing & Serving Tips
- Freeze the finished cake overnight for the best texture.
- To slice easily, dip your knife in hot water and wipe dry between cuts.
- Serve directly from the freezer — this cake is best enjoyed frozen.
Optional Add-Ins & Variations
- Use chocolate or peanut butter ice cream instead of vanilla for a flavor twist.
- Add a thin layer of crushed Oreos on top of the graham cracker crust for extra crunch.

- Top with whipped cream and a maraschino cherry for the full Dairy Queen effect.
