The first step is to add eggs an sugar to a large mixing bowl.
Then, using a hand-held electric mixer or whisk, beat at high speed for about 3 minutes until it is fluffy.
Next, combine flour with baking powder and salt in a separate mixing bowl. This is the time to add some of your favorite spices. I added cinnamon and nutmeg this time.
Incorporate the flour mixture into the egg mixture. Avoid overmixing; the batter should have small lumps. Fold the blueberries into the mixture with a spatula.
Now, if necessary, grease the waffle iron (some nonstick waffle makers do not need to be sprayed).
Pour the batter over it. The amount of batter should be determined by the manufacturer's instructions for your waffle maker. Make sure to do so to avoid batter spills.
Cook until golden brown. Must waffle makers have an indicator (timer) of when the waffles are done, just follow that.
