Using a blow torch, char three cinnamon sticks on both sides.
Let them cool down, break them into small pieces, blend them until you get a fine powder, and pass it through a sifter.
Place the softened butter, salt, a black pepper pinch, two teaspoons of charred cinnamon powder, a bit of freshly grated nutmeg, and the beans of half a vanilla bean pod in a mixing bowl and give it a good whisk until smooth.
Add the powdered sugar, and whisk vigorously to incorporate some air.
Add and incorporate honey.
