Place the ingredients in the blender in the order listed, making sure the milk is first to ensure a smoother batter. Blend for 1 minute. The batter will be thick, and depending on the blender, you might have to pause to scrape the sides. It's sometimes easier to measure and scoop the batter when you pour it into a bowl.
Cook the pancakes:
Heat a large non-stick pan (or griddle) over medium heat. Once hot, grease the surface with oil, spray, or butter. Immediately, pour ¼ cup of batter per pancake and use the back of the scoop or a spoon to gently spread it into 4-inch circles.
Cook the pancakes for about 2 minutes on the first side. Flip them over and cook for a little less time on the second side. Avoid pressing the pancakes with the spatula after flipping (they'll get dense). Remove them from the pan onto a plate and cover with a kitchen towel or keep them warm in the oven (set to 200F) on a sheet pan while you cook the rest.
Serve & Store:
Build your healthy pancake stack on a plate, topped with fresh fruit and light syrup.
Refrigerate leftover pancakes for up to 4 days. Reheat them for 30 seconds to 1 minute in the microwave or toast them. These freeze great, flat, in a zip bag, for up to 3 months.
Notes
Add-ins:
Add ½ to 1 teaspoon of cinnamon to the blender.
Add 1 teaspoon vanilla to the blender.
Pour the batter into a bowl and fold-in ½ cup of chocolate chips, finely diced strawberries, or blueberries.
For sweeter pancakes:
If your banana isn't very ripe, you can add 2 tablespoons of honey or maple syrup to sweeten the batter.
To ripen your banana in a pinch, peel the banana and microwave it in 15-second intervals, mashing it with a fork as it softens. This will quick-ripen the banana and bring out its sweetness. Then, allow it to cool down completely before making the batter.
This batter naturally has a mild, neutral flavor, so check that your baking powder is aluminum-free. The metallic flavor can often ruin the taste. If it's time to buy new, get the right baking powder.
