Healthy Vanilla Banana Birthday Cake for Kids

This Healthy Vanilla Banana Birthday Cake for Kids is soft, fluffy, gluten-free, dairy-free, and lower in sugar than a traditional birthday cake. Naturally sweetened with ripe bananas and coconut sugar, it's made with simple, wholesome ingredients and is perfect for birthdays, toddler celebrations, or anytime you want a healthier homemade dessert the whole family will love.
Notes:
- Use very ripe bananas with lots of brown spots for the best flavor and moisture.
- If your batter looks thicker than a typical cake batter, that's okay. It should be thick, but not dry or crumbly.
- For an extra fluffy texture, bring eggs and yogurt to room temperature before mixing.

Ingredients

  • 1 cup mashed very ripe banana (about 2 large bananas)
  • 3 large eggs
  • ¼ cup melted coconut oil slightly cooled
  • cup plain whole milk Greek yogurt or coconut yogurt
  • cup coconut sugar
  • 2 teaspoons vanilla extract or vanilla bean paste
  • 1 teaspoon apple cider vinegar
  • 2-3 tablespoons milk of choice
  • cups gluten-free 1:1 baking flour (I recommend using King Arthur Measure for Measure)
  • 2 teaspoons baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon cinnamon
  • ½ teaspoon sea salt

Instructions

  • Preheat the oven to 350°F. Grease and line an 8 or 9-inch round cake pan with parchment paper.
  • In a large bowl, whisk together banana, eggs, Greek yogurt, coconut sugar, vanilla extract, and apple cider vinegar until smooth.
  • Slowly whisk in the melted coconut oil.
  • Stir in the milk.
  • In a separate bowl, whisk together gluten-free flour, baking powder, baking soda, cinnamon, and sea salt.
  • Add the dry ingredients to the wet ingredients and stir until just combined. The batter should be thick but easily spreadable. Avoid overmixing.
  • Transfer batter to the prepared pan and smooth the top.
  • Bake for 26–30 minutes, checking around the 24-minute mark.
    The cake is done when the center springs back lightly and a toothpick inserted into the center comes out clean or with a few moist crumbs attached.
  • Allow the cake to cool in the pan for 10–15 minutes before transferring to a wire rack to cool completely.
  • Chill before frosting (option to make my Healthy Chocolate Date Frosting recipe), if desired. Enjoy!

To Make Ahead & Store:

  • Store the unfrosted cake tightly wrapped or in an airtight container at room temperature for up to 2 days, or refrigerate for up to 5 days.  
    Once frosted, store covered in the refrigerator for up to 5 days.
    For longer storage, wrap the unfrosted cake tightly and freeze for up to 3 months. Thaw overnight in the refrigerator before frosting and serving.

Notes

Swaps & Substitutions:
  • Greek yogurt: Plain whole milk Greek yogurt or plain unsweetened coconut yogurt both work well.
  • Gluten-free flour: King Arthur Measure for Measure is recommended, but another gluten-free 1:1 baking flour with xanthan gum should also work.
  • Coconut sugar: Substitute light brown sugar 1:1, if preferred.
  • Coconut oil: Swap with melted avocado oil or another neutral oil.
  • Milk: Use any milk of choice, including dairy, almond, oat, or coconut milk.
  • Vanilla: Vanilla extract and vanilla bean paste are interchangeable.
