In a mixing bowl, mash the bananas with a fork until smooth.
Add the eggs, almond flour, coconut flour, rolled oats, Greek yogurt, cinnamon, baking powder, maple syrup, and vanilla extract. Mix everything thoroughly with a fork. Stir in the choco chips and combine evenly.
Preheat the oven to 180°C (350°F). Line a baking tray with parchment paper and pour the mixture onto the tray.
Evenly distribute the blueberries on top of the mixture.
Bake for approximately 45 minutes or until a toothpick inserted in the center comes out clean.
Allow the cake to cool for at least 30 minutes before slicing.
Serve and enjoy your healthy, no-sugar cake! 😊
