In a mixing bowl, combine the whole wheat flour, baking powder, baking soda, salt, and sugar substitute. Whisk until well blended.
In another bowl, mix the almond milk, vanilla extract, and melted coconut oil or butter. Stir until combined.
Pour the wet ingredients into the dry ingredients. Mix gently until just combined; be careful not to overmix as this can lead to dense pancakes.
Heat a non-stick skillet or griddle over medium heat. Lightly grease with a little coconut oil or butter.
Pour 1/4 cup of batter onto the skillet for each pancake. Cook until bubbles form on the surface, about 2-3 minutes.
Flip the pancakes and cook for an additional 2-3 minutes, or until golden brown.
Remove from the skillet and keep warm while you repeat with the remaining batter.
Serve warm with your favorite toppings, such as fresh fruit or a drizzle of sugar-free syrup.
