Mix all the dry ingredients (all-purpose flour, sugar, baking powder, baking soda and salt) into a large mixing bowl. Lightly mix all the ingredients together with a wooden spoon or wire whisk to ensure there are no pockets of one single ingredient.
In a smaller mixing bowl, add the wet ingredients (egg, oat milk and light oil) and lightly beat the mixture with a wire whisk. Pour the wet ingredients into the dry ingredients.
Lightly mix all the ingredients together with a wire whisk until there is no longer dry flour in the mixing bowl. Do not over mix to keep the pancakes as airy as possible. It is okay if there are clumps in the batter.
Place a pan on the stove top and heat on medium-low heat. Spray the pan with cooking spray to prevent the pancakes from sticking onto the pan. Pour a ¼ cup of pancake mix onto the pan for each pancake. Once the pancakes start to bubble like shown in the photo below, it is time to flip the pancakes over and allow to cook for another minute or two.
Remove the cooked pancakes from the pan and place on a plate off to the side. Repeat until all the pancake batter is used up.
Top the pancakes off with your favorite toppings and enjoy!
