Combine dry ingredients in large bowl: flour, sugar, baking powder, baking soda, salt.
Add buttermilk, eggs and melted butter and mix just until wet and dry ingredients are incorporated. You don't want to over-mix the batter. Add milk, a little at a time until batter is still thick, but pourable.
Add toppings: Pour batter into greased 13x18’’ pan (bakers half sheet). Add toppings, if desired.
Bake at 425 degrees F for about 14-15 minutes. Cut into squares, and serve warm, with syrup.
