Preheat oven to 350ºF and adjust rack to middle position. Place all of the donut ingredients in a
large bowl and whisk until smooth. Spoon the batter into a buttered donut baking pan. Bake for
18-20 minutes until just turning golden brown on the edges. Cool completely.
Place the coconut sugar and coconut milk in a medium saucepan and whisk until combined. Heat over medium-high until boiling and then turn down to medium-low and simmer for 20-25 minutes until reduced and mixture has thickened. Cool for about 30 minutes.
To glaze the donuts: Pick up a donut and dip the top half in the cooled caramel and then place
on a cooling rack. Repeat with remaining donuts. Sprinkle with Celtic sea salt. Serve.
