I completely hear you. Two ideas:
~ the chocolate lava cakes at Trader Joe’s——- kindof a cop-out answer, but they are AMAZING (and easy to heat and affordable) – if you have one near you, try one, and then maybe there’s a local place with something similar or you can find a recipe. i’m overwhelmed with half of one of these.
~ in liquid form, I love making hot chocolate out of a really good dark chocolate (bar or powder), non-dairy milk (like almond, rice, soy, or hazelnut milk), a generous sprinkle of cinnamon, and a pinch of cayenne (or other hot spice). add the cinnamon and cayenne when it’s warm/hot so they dissipate instead of making balls. a store-bought version would be Dagoba’s xocolatl (it’s not on Dagoba’s website, so that’s a random link) or many types of Mexican hot cocoa (like this one) if you have a store nearby that sells that kind of thing.
