Thanks all!!! In the end I went with half chocolate and half salted caramel. Left out the nuts since they’re more polarizing and in case there’s any allergies at the dinner I’m going to. I had a little taste and I think they’re going to be really good.
PP, I agree that the flavor of blondies is just perfection by itself (I also prefer my chocolate chip cookies without chocolate) but I think we’re in the minority.
I used the cook’s illustrated Blondie recipe. Interestingly, the butter is just melted, not browned but they still have that caramel-y taste.
