First, I preheated my waffle iron so that can get niiiiiiice and hot while I mix up my batter.Then, I melted the butter and coconut oil in a small saucepan over medium heat.While that was workin', I whisked together the flours, coconut sugar, baking powder, baking soda and salt in a large mixing bowl, making a little well in the middle for my wet ingredients to hang out in.Then, I whisked together the buttermilk, vanilla and eggs in a large measuring cup, and poured that into my little flour well. I poured the melted butter combo in there too, then gave it a few good stirs just to incorporate everything. Your batter will be lumpy. That's totally cool, preferable even. We like our batter with some curves.I spooned up a couple big spoonfuls of batter into the waffle iron and let it do its thaaaang.I garnished each waffle with a little spoonful of vanilla yogurt and a few nectarine slices and blueberries.Then, I stuffed my face with waffles!
