These waffles were nice and light and lacked the graininess typical of baked goods made with whole wheat flour. I'm not sure if it was the soaking or the fact that I used whole wheat pastry flour. I'm really becoming a fan of buttermilk -- it adds such a nice flavor.
The batter was a pretty typical texture-wise when I used whole wheat pastry flour. Using regular whole wheat flour, the batter was much goopier than I expected. The waffles still baked up fine though.
