Combine the dry ingredients: In a large bowl, whisk together the flour, baking powder, and cinnamon until evenly distributed. The mixture should look fluffy and slightly clumpy.
Mix the wet ingredients: In a separate bowl, mash the ripe banana until smooth, then whisk in the plant-based milk, oil, and vanilla extract. The mixture should be fragrant and slightly frothy.
Pour the wet mixture into the dry ingredients: Gently fold everything together with a spatula or whisk until just combined. A few lumps are fine—this helps keep the pancakes tender.
Preheat your skillet: Set a non-stick skillet or griddle over medium heat and let it warm until a few drops of water dance on the surface. The pan should be hot but not smoking.
Pour batter: Using a 1/4 cup measure, pour the batter onto the hot skillet, leaving space between each pancake. Cook until bubbles form on the surface and edges look matte, about 2–3 minutes.
Flip the pancakes: Carefully slide a spatula underneath each pancake and flip them over. Cook for another 2 minutes or until golden brown and cooked through in the center.
Remove and keep warm: Transfer the cooked pancakes to a plate and cover loosely with foil or keep warm in a low oven. Repeat with remaining batter.
Serve immediately: Top with fresh fruit, a drizzle of maple syrup, or your favorite toppings. Enjoy the fluffy, golden texture of your homemade vegan pancakes!
