To help activate the yeast, microwave the milk for 40 seconds.
Add the yeast to the milk until a small foam forms.
In a bowl, mix the flour, sugar, baking soda, and salt.
In another bowl, gradually combine the butter, eggs, and flour, alternating with the milk.
Let the waffle batter rest for 30 minutes in a draft-free spot.
Brush your waffle iron with melted butter using a silicone brush.
Scoop about ¾ cup of waffle batter into the waffle iron, using a knife or spatula to evenly spread it across the bottom plate.
Close the waffle maker and flip it 180 degrees.
When the green indicator light turns on, flip the waffle iron back and remove the waffle.
Repeat for each waffle, remembering to butter the waffle iron each time.
Serve hot with syrup and fresh berries.
