Cut the stems off of the habanero peppers, then place the habaneros evenly across a foil lined baking sheet.
Bake the habaneros in the oven for 4 to 6 hours, until the chilies have dried. Depending on your oven, you may need more time.
Remove the habanero peppers from the oven, then place them in a food processor or mortar. Do not remove the seeds as that removes much of the habanero heat.
Whether automatically or by hand, crush the chilies until they reach your desired flake size.
Use immediately or store the habanero flakes in an airtight container.
Notes
Use gloves during the preparation of habanero flakes. Habanero peppers are extra hot and can cause significant chili burn.
