Put the coconut oil, milk, eggs, and vanilla into the pitcher of your blender.
Add dry ingredients on top of the liquid. (I measured the flour using the "scoop and level" method, not the "spoon and level". To understand why that's important and how each method affects your baked goods, check out the complete information in this post.)
Put the lid on the blender and blend just until the ingredients are thoroughly combined.
Pour waffle batter into preheated waffle iron and cook according to your appliance's directions. (Mine usually take less than 1 minute.)
Serve with your favorite syrups, fruit and toppings. I prefer Pure Maple Syrup and butter, unfortunately, I may have converted David to whole grains, but he still prefers commercial pancake syrup. One step at a time, right? :) Enjoy!
