Preheat your waffle iron. In a large bowl, whisk together the buckwheat flour, baking powder, baking soda, salt, cinnamon and ginger.
In a separate bowl or large measuring cup, combine the milk with the apple cider vinegar. Allow to to sit for a few minutes. Add the egg, maple syrup and molasses and whisk until smooth.
Pour the liquid mixture into the bowl with the flour. Using a spatula, stir a few times. Add the melted coconut oil then continue to stir until a smooth batter forms. If the batter seems a little thin, allow to sit for 5-10 minutes, until thickened.
Once the iron is preheated, scoop out about 1/4 cup of batter per waffle (this amount may vary depending on the type and size of your waffle maker). Close and cook until edges are firm and crispy. Remove and allow to cool on a cooling rack.
Reheat waffles in the toaster for maximum crispness. Serve warm with pure maple syrup and enjoy!
