In a large mixing bowl, whisk together the whole wheat flour, baking powder, cinnamon, and salt until evenly combined.
In a separate bowl, whisk together the egg, milk, and mashed banana until smooth. Add the melted coconut oil, brown sugar, Greek yogurt, and vanilla extract, then whisk until fully incorporated.
Pour the wet ingredients into the dry ingredients and gently stir until just combined. Avoid overmixing the batter. A few small lumps are perfectly fine and will help keep the pancakes light and fluffy.
If desired, gently fold in chocolate chips, chopped walnuts, blueberries, or your favorite mix-ins.
Heat a lightly greased griddle or large nonstick skillet over medium heat.
Pour about ¼ cup of batter onto the hot skillet for each pancake.
Cook for approximately 2 minutes, or until bubbles begin forming around the edges and the surface starts to look set.
Carefully flip each pancake and cook for another 1 to 2 minutes until golden brown and cooked through.
Transfer the cooked pancakes to a baking sheet in a 200°F (93°C) oven to keep warm while cooking the remaining batter.
