This is a recipe video for a rich, gluten-free chocolate cake made with rice flour. Simply mix eggs, milk, maple syrup, rice oil, rice flour, cocoa powder, and baking powder in a mug, add dark chocolate, and heat in the microwave for 90 seconds. The cake has a fluffy and chewy texture, and when served with whipped cream and cocoa powder, it offers an easy yet authentic taste. It's easier than a sponge cake and is perfect as a dessert for the New Year holidays.
