The no-bowl choc slice (or seven-layer bar in the US) is a magical confection in which a bunch of crunchy, sweet things are layered on top of each other and held together by sweetened condensed milk. They are very good, but very sweet, and — like everything — benefit from the addition of potato chips.

The video above will walk you through it, but it’s really just a matter of swapping out a sweet base like biscuit for a salty potato chip. You can doctor your own bar recipe or use the one linked below.
To make the base, pulse 280g of (thin) potato chips in a food processor with 3 tablespoons of flour. Add in four tablespoons of melted butter and pulse until the chips are “evenly moistened and finely chopped.” Press into a baking pan, bake at 180C until lightly browned, and then pile on the rest of your delicious layers according to whatever recipe you happen to be using.
