Using a measuring cup that holds at least two cups, fill it to the '1 cup' line with the buckwheat groats.

Add water to the groats until you reach the '2 cup' line.

Stir in the vinegar and oil.

Let the mixture sit and soak for at least two hours.

After the soak time, preheat the oven to 350 degrees.

Add the buckwheat mixture, salt, and baking soda to a blender.

Blend all until smooth.

Line a baking sheet with parchment paper.

Pour the buckwheat batter onto the parchment paper (it will be similar to pancake batter in consistency).

Spread it out a bit with a spatula.

Bake for 30 minutes.

Top with your choice of toppings.

Bake for another 10 minutes.

Cool, cut, and serve!
