How to Make Banana Cocoa Oatmeal Cake
Step 1: Preheat & Prepare
Preheat your oven to 175°C (350°F). Line your baking pan with parchment paper.
Step 2: Mash the Bananas
In a large bowl, mash bananas until mostly smooth. A few small lumps are perfectly fine.
Step 3: Add Wet Ingredients
Stir in maple syrup, melted coconut oil, eggs, and vanilla extract. Mix until combined.
The mixture should look glossy and slightly thick.
Step 4: Add Dry Ingredients
Add oat flour, cocoa powder, baking powder, baking soda, and salt.
Gently fold until just combined. Do not overmix.
Fold in chocolate chips if using.
Step 5: Bake
Pour batter into prepared pan and smooth the top.
Bake for 25–30 minutes, or until a toothpick inserted comes out mostly clean (a few moist crumbs are perfect for fudginess).
Step 6: Cool
Let cool completely before slicing. This step is key for clean, fudgy slices.
What to Serve with Banana Cocoa Oatmeal Cake
- Greek yogurt and berries
- Almond butter drizzle

- Use certified gluten-free oats if needed.
