Preheat your oven to 350°F (175°C). Lightly grease a small baking dish or line it with parchment paper.
In a mixing bowl, mash the bananas until smooth.
Add the eggs and whisk until fully combined.
Gently fold in the blueberries.
Pour the mixture into the prepared baking dish and spread evenly.
Bake for 25–30 minutes, or until set and lightly golden on top.
Let it cool for 10 minutes before slicing and serving.
