Start by mashing your ripe bananas in a large bowl. You want them soft and smooth — this is what gives the bars natural sweetness and moisture.
To the mashed bananas, add the egg, honey (or maple syrup), melted coconut oil, and vanilla extract. Whisk everything together until well combined.
In the same bowl, add the oats, cinnamon, baking powder, and salt. Stir until everything is evenly coated and no dry oats remain
If you want to add extras like chocolate chips, chopped walnuts, or dried cranberries, fold them in now.
Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving a little overhang on the sides so it’s easy to lift the bars out later.
Pour the mixture into the pan and press it down firmly with the back of a spoon or spatula.
Bake for 20–25 minutes, or until the top is golden brown and slightly firm to the touch. The edges should be lightly crisp while the center stays soft and chewy.
Let the pan cool completely before slicing
