Step 1: Prep the Oven and Pan
Preheat your oven to 350°F (175°C). Lightly grease your 8x8 inch square baking pan and line it with parchment paper, leaving an overhang on two sides to easily lift the cake out later.Step 2: Mash and Mix the Wet Ingredients
In your large mixing bowl, thoroughly mash the overripe bananas until they are almost smooth, with only small lumps remaining. Add the room-temperature eggs, olive oil (or melted coconut oil), maple syrup, Greek yogurt, and vanilla extract. Whisk vigorously until the mixture is uniform and well combined.Step 3: Whisk the Dry Ingredients
In a separate medium bowl, whisk together the white whole wheat flour, baking soda, baking powder, cinnamon, and salt. Ensure the leavening agents are evenly distributed throughout the flour.Step 4: Combine Wet and Dry
Pour the dry ingredient mixture into the large bowl containing the wet banana mixture. Using your rubber spatula, gently fold the ingredients together just until the flour streaks disappear. Do not overmix. Overmixing whole wheat flour will result in a tough, rubbery cake. If you are adding nuts, fold them in now.

Pour the batter into the prepared baking pan and smooth the top evenly. Bake for 45 to 55 minutes. The cake is done when the top is a deep golden brown and a toothpick inserted into the center comes out clean or with a few moist crumbs attached.Step 6: The Essential Cool Down
Let the cake cool in the pan on a wire rack for at least 30 minutes. This resting period is crucial; because the cake is so moist, attempting to slice it while hot will cause it to fall apart. Use the parchment paper overhang to lift the cooled cake out before slicing.
