Peanut butter and chocolate combos make me think of my favorite ice cream topping as a kid, which I used to make with rice crispies and crumble into tiny bites of deliciousness. Since hazelnut butter is kosher for Passover (unlike peanut butter, which is kitniyot), that’s what I use here – and while I was at it, I decided to be super original and throw in crushed potato sticks instead of rice crispies. It worked!
