I’ve made many different lightened up waffle recipes, and this is my fave because of the texture (crisp outside fluffy inside) and because they have some protein. For flour I used half 1:1 GF + half regular white. I also added an additional 1/2 cup oat flour because my batter was too runny. However, when i poured the final batter out, I realized the reason it was originally too runny was because a lot of flour was stuck in the bottom 4 corners of the blender. This happened despite pre-blending all the liquid stuff first, despite having a Vitamix, and despite scraping down sides a couple of times. I did add a couple of Tbs of maple syrup to the batter to sweeten a little. I will definitely make again, but I will forgo blender and just mix by hand. My toddlers like them too. And they do great being frozen then reheated in toaster.
