Step 1

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) springform pan and press crumbs evenly into the bottom of the pan with the back of a flat-bottomed cup. Freeze for about 30 minutes.

Step 2

In a large bowl, stir ice cream with a wooden spoon to soften, for about 1-2 minutes. Add 1 cup of peanut butter and 5 oz peanut butter cups to the ice cream and stir until combined. It's absolutely fine when peanut butter swirls are still visible. You don't need to work that accurately.

Step 3

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.

Step 4

Place the chopped chocolate bars, sweetened condensed milk, and heavy cream in a heat-proof bowl and microwave for about 2 minutes until it has the typical chocolate fudge consistency. Stir every 20 seconds, that the chocolate doesn't get too fast too hot. Pour, drizzle, or spread on top of the cake. Freeze the cake for at least two hours.

Step 5

Serve with whipped cream, meringue, or additional toppings of your choice. Store leftovers up to 2 weeks in the freezer.
