Preheat your griddle over medium heat. Then mash the banana and avocado into a medium mixing bowl and pour in the milk. Mix well.
Next, add the flour, sugar and baking powder. Then stir until combined without overmixing.
Ladle your batter on your preheated griddle, making pancakes roughly 4 inches in diameter. Cook for 4-5 minutes until the edges are golden brown and there are several bubbles on top.
Then flip and continue cooking until the pancakes are cooked through.
Notes
Weigh your flour for the most accurate results. Scooping from a bag often results in too much flour being used due to compacting the flour into the measuring cup.
If you do not have a kitchen scale, spoon the flour into your measuring cup and scrape off the top with a knife, but do not scoop from the bag.
Use fresh, active baking powder. Baking powder that has been opened and sitting in the pantry for several months can start to lose its effectiveness.
No need to overmix your pancake batter. If there are a few lumps, that’s perfectly fine. Just mix until combined and no floury bits remain.
Preheat your pan or griddle. It should be hot before pouring your pancake batter to prevent sticking and for even cooking.
Use medium heat to cook your pancakes. Although your pan should be hot, that doesn’t mean you should use high heat. This may result in uneven cooking, with crisp outsides and mushy middles.
Flip your pancakes ONCE when the edges are golden brown and have several bubbles on top. Flipping too often can cause them to deflate and make a denser pancake texture.
Leftovers keep in the fridge for 2-3 days or frozen for up to 3 months.
