Preheat the oven to 400F and position the top oven rack in the middle of the oven. Grease a 12-muffin pan. Do not use paper liners; they'll stick.
Add the following ingredients to a blender in the order listed: cottage cheese, bananas, eggs, honey, vanilla, baking powder, cinnamon, and oats. Blend for 45 seconds on high speed, until the batter is smooth.
Bake:
Pour the batter into the muffin pan, filling each cup ¾ of the way to the top.
Bake for 20 minutes, until the tops are brown and a toothpick inserted in the middle comes out clean.
Remove from the oven and let them cool in the pan for 10 minutes before removing them.
