Photo instructions

In a bowl, stir together the graham cracker crumbs, peanut crumbs, peanut butter, and melted butter until fully combined and evenly moist.

Transfer the crumbs to a 9-inch (23cm) baking pan and press crumbs evenly into the bottom of the pan with the back of a flat-bottomed cup. Freeze for about 30 minutes.

Remove the crust from the freezer and fill the half of the ice cream into the pan.

Spoon dollops of the remaining peanut butter on top of the ice cream. Even and swirl it into the ice cream with an offset spatula or spoon.

Sprinkle with the remaining peanut butter cups.

Spoon the remaining ice cream on top and spread evenly.

Freeze the cake for at least 8 hours but preferably overnight.

Top Tips

• Don’t skip freezing. That is what makes it set up so you can cut it nicely.
• Due to the high amount of whipping cream, the ganache will stay soft even after it’s frozen. This is completely normal.
• The best way to cut it is to set it on the counter about 5 minutes before you are ready to serve it. That gives it a little time to thaw slightly. Don’t go much longer than that because it will begin to melt.
• Warm a large knife under hot water for cutting. After each cut, you will need to wipe off the knife and run it under hot water. Follow these tips, and you will end up with perfect slices.

Substitutions

Consider substituting any of the following:

• Use crushed Oreos instead of graham crackers.
• Replace half the peanut butter cups with Snickers, milk chocolate bars, or any other kind of candy bar you prefer.
• Replace chocolate chips with peanut butter chips for the ganache topping.
• Trade vanilla ice cream for your favorite chocolate ice cream to make it even richer.

Additional flavors

• Add ½ cup (25g) of mini marshmallows on top.
• Sprinkle ½ cup (30g) of crushed pretzels as a garnish.
• Mix 1 cup (175g) of peanut butter chips or white chocolate chips into ice cream mixture.

To make a s’mores version of this cake add the following:

• Add 7oz of marshmallow fluff when you add the peanut butter and peanut butter cups.
• Top with meringue after you applied the ganache.

Storage

It needs to be stored in the freezer in an airtight container. It will last for up to 2 weeks. If you notice a lot of ice crystals or it doesn’t taste good anymore, then it may have started going bad, and then it would need to be tossed.

Except for cutting, keep it in the freezer all the time. Don’t let it set out for too long. If it seems to have melted a fair amount, then it might not hold up very well to be frozen again.
