Preheat the oven to 350°F. Generously coat a 9x13-inch baking dish with nonstick cooking spray, making sure to spray the corners for easy release.

Add bananas, oats, Greek yogurt, milk, eggs, monk fruit sweetener, baking powder, cinnamon, vanilla extract, and salt to a blender. Blend on high until a smooth, pourable batter forms, about 1 minute.
03 -
Let the blended batter sit in the blender for 5 minutes to allow the oats to absorb some liquid and improve the final texture.
04 -
Pour the batter evenly into the prepared baking dish. Sprinkle half of the chocolate chips over the top, then gently swirl some chips into the surface with a knife for even distribution.

Transfer the pan to the oven and bake for 35–40 minutes, or until the edges are golden, the center is set but still slightly jiggly, and a toothpick inserted near the center comes out mostly clean.

Remove from the oven and let cool in the pan for at least 10 minutes before slicing for clean portions. Serve warm, optionally with additional chocolate chips, maple syrup, or fresh berries.
