I’m not going to pretend I invented this. A quick Google search for saltine toffee bark or some variation of that will turn up this super simple recipe. I think the only adjustment I made was the amount of butter I used (spoiler: it was more than most recipes you’ll find out there). Why the change? First it was by accident; doubling the initial amount. I learned from people that they actually liked it a little chewy. I, unfortunately, didn’t but I found a nice little compromise that allowed it to be toffee-like but not break your teeth.
