Melt the butter in a small bowl and set aside for 3-5 minutes to allow it to cool slightly.
In a large bowl, mix together the cornmeal, oat flour, baking powder and salt.
In a medium bowl mix the butter with water, vinegar, honey and eggs.
Make a well in the center of the dry ingredients and pour the wet ingredients into it. Mix until just combined.
Line a 12 count muffin pan with paper or silicone liners. Divide the batter evenly among them, filling each about ¾ full.
Bake for 14-18 minutes until the centers bounce back slightly when pressed and a toothpick poked in the middle comes out with just a few crumbs.
Serve warm with extra butter and honey.
