Finalizing

  4. Let it cool slightly before serving warm.

Notes

For an extra touch, serve with whipped cream or vanilla ice cream. Store leftovers in an airtight container in the refrigerator for up to three days, or freeze tightly wrapped for a couple of months. Experiment with high-quality cocoa powder or add nuts for variation.
