Preheat your waffle iron.
Combine the flour, sugar, baking powder, and salt in a large bowl or large glass measuring cup (at least 4 cup size).
Mix the dry ingredients well.
Create a well in the center of your flour mixture.
Add the wet ingredients to the dry ingredient mixture.
Mix thoroughly, taking care to scrape the sides and bottoms of the measuring cup.
If your waffle iron needs to be greased ahead of pouring in the batter, do that now.
Pour the batter using a measuring cup or ladle into the preheated waffle iron. My waffle iron uses about ¾ cup batter.
Note: Depending on the size of your waffle iron, you may need more or less batter. However, the batter when initially poured, should be enough to fill just the center leaving the edges bare as the batter will rise and spread significantly.
Follow the cooking instructions that came with your waffle maker for the appropriate time, for my machine it is about 2.5-3 minutes per waffle. Usually, as the steam from the waffle begins to slow or stop, they are done.
Serve with butter and maple syrup and enjoy!
