Roasted Sweet Potato with Chocolate Magic Shell

First, roast a sweet potato until it's tender and sweet (the longer the better). Let the roasted potato cool slightly to avoid burning your mouth. Melt the dark chocolate with a little olive oil until smooth. After adding the melted chocolate to the sweet potato, place it in the freezer for a few minutes until the chocolate hardens enough. Note that it won't be as hard as a typical magic shell if you want the potato to remain warm.
