Why Oat Banana Cake Deserves a Spot in Your Recipe Book

Bananas and oats are two pantry staples that shine when baked together:

• Bananas bring natural sweetness, potassium, and moisture to the cake, eliminating the need for large amounts of refined sugar.

• Oats (especially rolled or quick oats) add a hearty texture, soluble fiber, and a nutty flavor that makes the cake more filling.

The result? A wholesome cake you can enjoy guilt-free, whether you pair it with your morning coffee or serve it as an after-school snack.

Step-by-Step Instructions

Step 1: Prep the Oven and Pan

Preheat your oven to 350°F (175°C). Grease and line a 9-inch round or square baking pan with parchment paper.

Step 2: Mix the Dry Ingredients

In a large mixing bowl, combine oat flour, rolled oats, baking powder, baking soda, salt, and cinnamon. Stir until evenly distributed.

Step 3: Prepare the Wet Mixture

In another bowl, mash the bananas until smooth. Whisk in the eggs, honey (or maple syrup), milk, oil, and vanilla extract until well combined.

Step 4: Combine Wet and Dry

Pour the wet mixture into the dry ingredients and stir gently until just combined. Avoid overmixing to keep the cake tender.

Step 5: Add Extras

If you’re using nuts, raisins, or chocolate chips, fold them in now.

Step 6: Bake

Pour the batter into the prepared pan and smooth the top. Bake for 30–35 minutes, or until a toothpick inserted into the center comes out clean.

Step 7: Cool and Serve

Allow the cake to cool for at least 10 minutes before slicing. Serve warm or at room temperature.

• Don’t skip the cinnamon: It enhances the banana flavor and adds a cozy aroma.

• Vegan option: Swap the eggs for flax eggs (1 tbsp ground flax + 3 tbsp water per egg) and use plant-based milk.
