Mix together the melted butter, date sugar, and date syrup in a bowl. Stir in the eggs and the yogurt and milk mixture. Add in the dry ingredients and stir until there are relatively few clumps (don’t over-mix!), followed by the corn.
Pour into a greased 10-inch (25cm) cast iron skillet or 9x9 in. (23x23cm) square baking dish. Bake at 375°F/190°C for 25-35 minutes, or until a toothpick comes out clean.
