I’ve perfected this incredibly moist and rich chocolate cake that uses the natural sweetness of ripe bananas and the wholesome goodness of oat flour. This recipe transforms simple, nutritious ingredients into a decadent dessert that satisfies chocolate cravings while keeping things healthy. The combination of bananas and cocoa creates an intensely chocolatey experience without the need for refined sugars or processed flour.
Why This Recipe Works

The result is a cake that’s incredibly moist and fudgy, with a perfect balance of chocolate and banana flavors. Plus, it’s naturally gluten-free and dairy-free!
