Ingredients
Method
- Preheat oven to 350°F (175°C). Grease and flour a 9x9-inch cake pan or use 8x8-inch for taller cake.
- In a medium bowl, whisk together flour, baking powder, baking soda, salt, chia seeds, cinnamon, and nutmeg.
- In a large bowl, mix sugar, coconut oil, and applesauce until smooth. Add mashed bananas and vanilla extract.
- Gradually stir dry ingredients into wet mixture until just combined. Do not overmix.
- Pour batter into prepared pan. Smooth top with spatula.
- In a small bowl, mix flour, sugar, and coconut oil to make crumb topping. Sprinkle over batter.
- Bake for 30–35 minutes. Check doneness with a toothpick.
- Let cake cool in pan for 10 minutes. Transfer to wire rack to cool completely before slicing.
Notes
Let batter rest for 5–10 minutes before baking to allow chia seeds to hydrate. For vegan version, use plant-based yogurt and protein powder. Any neutral oil can replace coconut oil. Store cake in an airtight container for 2 days at room temperature, or refrigerate for a week.
