In a large bowl, whisk together the cornmeal, flour, sugar, baking powder, and salt.
Pour plant-based milk, coconut milk, and 1 tablespoon melted vegan butter to the dry ingredients, stirring until just combined. The mixture will be a bit runny; let it rest for 15 minutes.
Place a cast iron skillet in the preheated oven for about 5-10 minutes. Then grease it with remaining 3 tablespoons of melted vegan butter.
Pour the batter into the prepared skillet, spreading it evenly. Bake in the preheated oven for 20-25 minutes, or until the top is golden and the edges are nicely browned .
Serve immediately with additional vegan butter.
