Preheat your oven to 350°F (175°C) and grease a baking dish.
Combine mashed bananas, whole wheat flour, Greek yogurt,honey or maple syrup, baking powder, and vanilla extract. Mix to form a soft dough.
Roll out the dough into a rectangular shape on a lightly floured surface. Sprinkle ground cinnamon over the rolled-out dough to infuse it with warm, comforting flavor. Carefully roll the dough into a log, similar to how you would roll a cinnamon roll. Slice the log into individual rolls and arrange them in a baking dish.
Bake for about 20 minutes until they're golden brown and fragrant, creating a delightful aroma.
After baking, you can also drizzle a yogurt-based glaze or a touch of honey over the rolls for extra sweetness. Once cooled slightly, these healthy banana cinnamon rolls are ready to be enjoyed as a wholesome treat.
