Preheat your waffle maker to desired setting–medium-high heat worked for me!
In a measuring cup, add the milk and ACV together, stirring to combine and letting them sit for 5 minutes.
In a large bowl, whisk together the flour, cornmeal, baking powder, baking soda, apple spice blend, and sea salt. Create a well in the middle.
Add the milk-ACV mixture, coconut oil, apple butter, Agave, and vanilla in the well of the dry ingredients and stir together well (using a rubber spatula) until fully incorporated and batter looks smooth.
Now, let the batter sit for 2-3 minutes while it slightly thickens and rises, which means that the ingredients have activated. NOTE: the batter should be pourable but not 'runny' at all. It should slightly stick when whisk is lifted up, as a test for thickness. NOTE: DO NOT OVER-MIX!
Next, spoon batter into your waffle maker (½ cup approximately) and cook according to your waffle iron’s instructions.
Once each waffle completes, add to a baking sheet and place them in the oven on the lowest setting (to keep them warm). Repeat until all waffles are made.
