Instructions:

1. **Preheat Oven**: Preheat your oven to 350°F (175°C). Grease a 9-inch round cake pan or line it with parchment paper.

2. **Mix Wet Ingredients**: In a large mixing bowl, combine mashed bananas, eggs, honey or maple syrup, melted coconut oil, and vanilla extract. Mix until well combined.

3. **Combine Dry Ingredients**: In another bowl, whisk together almond flour, baking powder, baking soda, cinnamon, and salt.

4. **Combine Wet and Dry Ingredients**: Gradually add the dry ingredients to the wet ingredients, stirring until just combined. Be careful not to overmix. If using chopped nuts, fold them into the batter.

5. **Bake**: Pour the batter into the prepared cake pan and spread it evenly. Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted into the center comes out clean.

6. **Cool**: Allow the cake to cool in the pan for about 10 minutes, then transfer it to a wire rack to cool completely.

7. **Serve**: Once cooled, slice and serve the banana cake. You can enjoy it as is or top it with a dollop of yogurt, whipped cream, or your favorite frosting.

Enjoy your delicious almond flour banana cake!
