This recipe came out pretty well. I used about half a cup of batter for each /side/ of the waffle iron, and it yielded 6 waffles (with a little extra batter.)

1 1/2 cups white whole wheat flour (from Trader Joe's)
2 teaspoons baking powder (**the next time I cut this down to 1.5 tsp so they'd be a tad less airy. I think I prefer that.)
1/2 teaspoon salt
2 tablespoons sugar
1 large egg
1 1/2 cups lukewarm milk (I warmed it in the microwave for 30 seconds in a glass cup - would have done it longer, the butter still re-solidified a little)
1/3 cup melted butter (I used salted and omitted added salt)
Preheat your iron while you make the waffle batter.
Whisk together the flour, baking powder, salt, and sugar.
In a separate bowl, whisk together the egg, milk, and butte
Mix together the wet and dry ingredients, stirring just until combined. (I used a spatula)The batter will be a bit lumpy; that's OK.
Cook the waffles as directed
I used not-the-hottest setting. (4/5?) I think something more like 3.5/5 would have been better - the first few were a tad overdone.
I ate them topped with sour cream (sweetened with some sugar) and frozen strawberries, defrosted.
