Its rare I treat myself to some B&J, they are ****ing $7 here!
What I do when is get some regular vanilla ice cream, buy a few cookies and just crush them as topping. First Ill wait for the ice cream to get like real soft, then I mix in the crumbs of cookies. If I feel wild I add some chocolate sauce
Once (not sober) I took a ice cream cake, put a different ice cream cake on top of it, and whipped cream, chocolate sauce with nuts and sliced bananas on top of that. Cant remember how it tasted but it was magical!
