Heat a griddle or a skillet over medium high heat. Add a little bit of butter and once melted and hot, pour about 1/4 cup of the pancake batter into the skillet. Cook for 2-3 minutes a side until golden brown on each side, flipping the first side over once bubbles form and batter begins to dry up.
Enjoy with pure maple syrup or honey!
