In a medium bowl, combine all of the dry ingredients and whisk thoroughly. Cut 2 tablespoons butter into the masa mixture.
In a different bowl, combine all of the wet ingredients, except the rest of the butter, and whisk thoroughly. Combine the wet ingredients with the dry. Allow the mixture to sit for 5 minutes.
While you let the mixture sit, place remaining butter into a 8x8 square pan or 8" cast iron pan and place in oven until melted.
Bake for 20 minutes and cut into 8 pieces for a circle pan and 9 pieces for a square pan.
