Make the rainbow waffles by combining flour, sugar, and baking powder in a bowl. In another bowl, lightly beat eggs, then add milk, butter, and vanilla; mix well. Stir into dry ingredients just until combined.

Divide batter evenly between 6 bowls. Add a few drops of red food coloring into the first bowl, stirring until uniformly distributed and desired shade is reached. Continue coloring batter in the remaining bowls: orange, yellow, green, blue, and purple.

Follow instructions for your waffle maker. Cook waffles one at a time until all batter has been used. Stack the waffles in a rainbow pattern, red at the top, then orange, yellow, green, blue, and purple. Or you can start with purple at the top and end with red.
