Preheat your oven to 200°F—this will keep finished pancakes warm while you cook the remaining batches. Measure out all your ingredients and have them ready by the stove. Bring your eggs to room temperature if they've been in the fridge, as this helps them emulsify better into the batter for a fluffier texture.

Add the oats to your blender and grind them into a fine flour-like consistency—this creates the dry base for your pancakes. Then add the ripe bananas, Greek yogurt, milk, room-temperature eggs, honey, and vanilla extract. Blend for about 2 minutes until the mixture is completely smooth with no lumps. The bananas will naturally sweeten the batter and provide moisture, which is why using well-ripened bananas with brown spots is essential for best flavor.

Add the baking powder, cinnamon, salt, and nutmeg to the blended mixture and pulse just until combined—don't overmix, as this can make the pancakes dense. Pour the batter into a bowl and let it sit for 10 minutes. This resting period allows the oats to fully hydrate and the leavening agents to activate, which results in fluffier, more tender pancakes. I find this step makes a noticeable difference in texture.

Heat a non-stick skillet or griddle over medium-low heat and lightly oil it. Pour about 1/4 cup of batter onto the hot surface for each pancake. Cook for about 3 minutes until the bottom is golden and the edges look set, then flip gently and cook for another 1-2 minutes on the second side. Transfer cooked pancakes to the preheated 200°F oven to keep warm while you finish the remaining batter. I recommend cooking over medium-low rather than high heat because these pancakes are delicate and cook best with gentle, even heat.

Remove the warm pancakes from the oven and stack them on serving plates. Serve immediately while still warm with your choice of toppings such as fresh berries, Greek yogurt, honey drizzle, nuts, or maple syrup.
