We can only think of one word to accurately describe these decadent Hello Dolly-inspired bars: Wow. The coconut on top crisps up beautifully, while the espresso chips add something extra indulgent. Serve these with ice cream or on their own. You'll be tempted to dig in as soon ASAP, but try to restrain yourself—the bars need to cool completely before you cut them. They should set up after an hour in the fridge but, for even better results, you could let them chill overnight.
