You will need 2 medium to large bowls.
In one bowl whisk together all of the dry ingredients.
In the other bowl beat the eggs, then whisk in the butter. Lastly, whisk in the buttermilk.
Add the wet ingredients to the bowl of flour mixture, stirring with a rubber spatula. Don’t over mix or it will become too dense. Set this aside to rest for 5 minutes.
Meanwhile, coat the waffle plates with vegetable oil spray, unless you anticipate that the batter won’t stick, and insert them into the grill. Turn the heat on to the highest setting or 400°F, depending on your machine model. Close the top and allow the grill to preheat. The red indicator light will come on when the grill is ready.
Pour or ladle the waffle batter onto the bottom plate until it is covered but not overflowing, approximately 2/3 cup. As soon as the batter starts to form air bubbles at the outer edges (approximately 1 minute), close the top of the grill and cook for another 5 minutes.
Open the top to see if the waffles are the color you like. If not, close the lid for another minute or two.
After opening the lid, unplug or turn off the grill. Allow the waffles to slightly cool for a minute. Then remove them with tongs or a fork.
Serve warm with your favorite toppings, such as maple syrup, chocolate chips, or banana slices and toasted nuts.
