This recipe yields a delicious, yet structurally fragile, maple banana cake perfect for small celebrations or immediate enjoyment. While initially considered for a “smash cake” style presentation, the cake’s delicate nature requires careful handling. The flavor profile balances sweetness from ripe bananas with the tang of a Greek yogurt frosting, though keeping it fresh requires attention to temperature.
Understanding the Recipe’s Nuances
The recipe is designed to be adaptable. Maple syrup provides a natural sweetness, but refined sugar can create a sturdier, easier-to-frost cake. Greek yogurt offers a light, tangy frosting, but its instability at room temperature means it must be served shortly after assembly or replaced with a more stable cream cheese-based alternative.
The original author is upfront about the cake’s fragility, which is a key consideration. This isn’t a recipe for elaborate decorations or extended display. It’s a fresh-baked treat best enjoyed soon after preparation.
Ingredients & Adaptations
The recipe calls for:
- Cake:
- ½ cup maple syrup
- ¾ cup mashed, overripe bananas (about one medium)
- ⅓ cup warmed coconut oil
- 1 tsp vanilla extract
- 2 room-temperature eggs
- 1 ¼ cup all-purpose flour (or cake flour for a lighter texture)
- ¾ cup quick-cooking oats (or pulsed old-fashioned oats)
- 1 tsp baking powder
- ½ tsp baking soda
- ½ tsp cinnamon
- Pinch of sea salt
- Frosting:
- 2 Tbsp room-temperature butter
- 2 Tbsp room-temperature cream cheese
- 6 oz full-fat Greek yogurt
- 1 cup powdered sugar (maple flavored optional)
- Dash of vanilla extract
Substitutions:
- Egg-free: Use a flax egg (1 Tbsp flaxmeal + water)
- Gluten-free: Substitute GF 1:1 flour for whole wheat pastry flour
- Banana alternative: Canned pumpkin can be used in a pinch.
Instructions: Baking & Frosting
- Preheat & Prepare: Preheat oven to 350°F (175°C). Grease and line an 8-inch round cake pan (or three 6-8 inch rounds for thicker layers) with parchment paper.
- Combine Wet Ingredients: In a large bowl, mix maple syrup, mashed bananas, coconut oil, vanilla, and eggs until well combined.
- Add Dry Ingredients: Gradually add flour, oats, baking powder, baking soda, cinnamon, and salt. Mix until just combined. Do not overmix.
- Bake: Pour batter into prepared pan and bake for 30 minutes, or until a toothpick inserted into the center comes out clean. Let cool completely.
- Make Frosting: In a mixer, beat butter and cream cheese until smooth. Add Greek yogurt, powdered sugar, and vanilla. Mix until combined.
- Frost & Serve: Frost the cooled cake immediately. The Greek yogurt frosting is best served cold and does not hold well at room temperature. For a more stable frosting, use a higher powdered sugar ratio or substitute with a cream cheese-based frosting.
This cake is delicious, but its delicate nature means it’s best enjoyed fresh. Expect a moist, flavorful treat that requires gentle handling.
The key to success is understanding that this isn’t a cake for perfectionists. It’s a recipe for a simple, enjoyable dessert that prioritizes flavor over flawless presentation.
