In a medium bowl, mash the banana using a fork until it resembles a paste. You want to minimize big chunks so the pancakes don't fall apart.Tip: put the banana inside a zip bag, mash it with your hands, cut the tip of the bag to make an opening, and squeeze the banana paste into the bowl.
Add the egg to the bowl and whisk with a fork until it's mixed into the banana paste. Then, add the all-purpose flour (or oat flour) and mix until combined. You can also add a dash of cinnamon for flavor.
Let the batter sit in the bowl for 5 to 10 minutes before cooking. This helps the flour absorb some of the moisture and improve the pancake texture.
Cook the pancakes:
Heat a non-stick griddle or large pan over medium heat. Once it's hot, grease with oil, spray, or butter. Immediately pour 2 tablespoons of batter onto the pan per pancake. You want to keep these small.
Cook the pancakes for 2 minutes per side. If they're browning/burning too quickly on the first side, your heat is too hot. If necessary, rinse the pan between each batch to lower the temperature.
Serve & store:
Serve warm with fresh fruit. Leftovers keep in the fridge for up to 4 days. These can also be frozen for up to 3 months and warmed in the microwave or toaster.
Notes
Flour adds texture to the pancakes and makes them easy to hold and for kiddos to self-feed. All-purpose or whole-wheat flour (12+ months) and oat flour (6+ months). You can make oat flour by blending oats in a blender until they're a fine powder.
