Grab a large mixing bowl. Toss in your baking powder, flour, a pinch of cinnamon, and a bit of salt. Give it a good whisk, then set that bowl aside for a moment.
In another big bowl, crack one large egg and pour in the milk. Mash up a ripe banana and whisk it in until smooth. Next, add in the brown sugar, oil, yogurt, and a splash of vanilla extract. Whisk it all together until combined.
Pour these wet ingredients (from Step 2) into your dry ingredient bowl (from Step 1). Use your whisk to gently mix everything and make sure no dry flour lingers at the bottom.
Heat a big skillet or griddle over medium heat and coat the surface generously with nonstick spray or butter.
Drop or pour a full ¼ cup of batter onto it. Let it cook until all the edges start to look more set and tiny bubbles form around them. Flip it over and keep going until all the sides of the pancakes are cooked through and lightly browned. Repeat for each of your batter batches.
(Optional) Place the pancakes in a preheated oven at 200°F (about 93°C) so they will stay cozy there until you’re ready to serve.
Serve up these fluffy pancakes with whatever toppings that make your heart happy. Enjoy!
