In a medium bowl, combine 1 1/3 cups flour, 2 teaspoons baking powder, a pinch of salt, and 2 tablespoons sugar.
Whisk together until thoroughly mixed and set aside.
In another bowl, mash the ripe plantain with a whisk or fork. Then add 1 1/4 cups soy milk, 1 teaspoon lemon juice, and 1 teaspoon vanilla extract and whisk everything until smooth.
Ensure all ingredients are well incorporated.
Pour the wet ingredients into the bowl with the dry ingredients. Whisk vigorously until the mixture forms a smooth batter, ensuring there are no lumps.
Optionally, refrigerate the batter for up to 30 minutes to improve texture.
Heat a frying pan over medium heat. Grease the pan lightly with vegan butter or oil to prevent sticking.
Optionally, fry slices of plantain in the hot pan until golden on both sides. Set aside.
Once the pan is hot, pour a scoop of batter onto the pan for each pancake. Allow the batter to spread naturally into circular shapes.
Cook the pancakes until bubbles form on the surface and begin to burst, indicating the bottom is cooked. This typically takes 2-3 minutes.
Carefully flip each pancake using a spatula and cook for an additional 1-2 minutes on the other side, or until both sides are golden brown and cooked through.
Remove the pancakes from the pan and transfer them to a plate.
Repeat the cooking process with the remaining batter, adjusting the heat if necessary to prevent burning.
Serve the pancakes warm, optionally topping them with the fried plantain slices, plant-based yogurt, maple syrup, or your favorite fruits. Enjoy your delicious vegan pancakes!
