- Salted Peanuts – Provide the signature salty crunch, offering the perfect contrast to the sweet elements.
- Hot Fudge Sauce – A thick, chocolatey topping that ties everything together. In this recipe, you’ll make it from scratch!

How to Make Buster Bar Ice Cream Cake (Step-by-Step)
Make the Crust: Combine crushed Oreo cookies and melted butter in a bowl. Press this mixture firmly into the bottom of a 9×13-inch pan to create a firm base. Chill it briefly while you prepare the next layers.
Layer the Ice Cream: Spread softened vanilla ice cream evenly over the crust. This layer should be smooth but firm enough not to melt quickly. Sprinkle one cup of salted peanuts across the ice cream layer. Place the pan in the freezer to let it firm up.
Prepare the Homemade Fudge Sauce: In a medium saucepan over medium heat, combine the semi-sweet chocolate chips, evaporated milk, sugar, and butter. Stir the mixture continuously until it reaches a boil, then let it boil for 8 minutes, stirring occasionally to prevent burning. Remove from heat and mix in the vanilla extract. Let the sauce cool to room temperature before using.
Add the Fudge Layer: Once the sauce is completely cooled and the ice cream layer is firm, pour the fudge sauce over the cake. Spread it gently for an even coating. Sprinkle the remaining salted peanuts on top.
Freeze and Serve
Freeze: Return the pan to the freezer and allow the cake to freeze for at least 4 hours, or overnight for best results. This helps all the layers set perfectly and gives you clean slices.
Serve: When you’re ready to serve, use a sharp knife to cut the dessert into bars or squares. Let it sit at room temperature for 3–5 minutes before slicing to make it easier to cut through. Serve frozen and enjoy that rich, creamy, crunchy goodness in every bite!
Storage and Freezing Instructions
- Storage: Cover the pan tightly with plastic wrap and foil, or use an airtight lid.
- Freezer Life: Stays fresh and tasty for up to 2 weeks in the freezer.
- Leftovers: You can wrap individual pieces in parchment and foil for easy grab-and-go servings.
Expert Tips for the Perfect Buster Bar Ice Cream Cake
- Soften Ice Cream Slightly: Let the ice cream sit out for 5–10 minutes before spreading so it layers easily without melting too fast.
- Chill Between Layers: Freeze after the ice cream layer before adding fudge to prevent mixing or sliding.
- Use a Hot Knife to Slice: Run your knife under hot water, wipe it, and then slice — repeat between cuts for clean edges.
- Customize the Nuts: Swap peanuts with almonds, cashews, or go nut-free if needed.
- Double the Recipe: Making it for a large crowd? Just use two pans and double the ingredients.
