As a quick ASMR trigger in the middle of a work day, Justin's Honey Peanut Butter and any good dark chocolate can't be beat. The recipe is simple: smear a wadge of peanut butter over a shard of chocolate. Adjust proportions to taste.
The gourmet peanut butter has a boosted sweetness and saltiness to complement cocoa. And though Justin's also sells pre-made dark-chocolate cups, I like my own ratio. Dark chocolate bars also offer stronger flavor than thin-walled cups.
