For the Cake

  • Butter and whole wheat flour for the pans
  • 1 cup white whole wheat flour
  • ½ teaspoon baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon cinnamon
  • 1/8 teaspoon salt
  • 1 medium ripe banana (about 3 ounces)
  • 1/3 cup unsweetened applesauce
  • 1/4 cup whole milk
  • 1/4 cup pure maple syrup
  • 1 large egg
  • 1 teaspoon vanilla extract

These ingredients create a soft, naturally sweet cake that feels lighter and more nourishing than many traditional birthday cakes.

White Whipped Cream Frosting

  • 1 cup heavy whipping cream

This simple frosting keeps the cake airy, creamy, and gently sweet.

Purple Whipped Cream Frosting

  • 1 cup frozen blueberries
  • 1/4 cup water
  • 1 cup heavy whipping cream

The blueberry version adds a naturally colorful and cozy homemade twist perfect for a cheerful birthday cake.

How to Make It

This easy baking method keeps the cake soft, moist, and perfectly balanced for a cozy homemade dessert.

Prepare the Cake Pans

Preheat the oven to 350°F.

Butter two small cake pans and lightly dust them with whole wheat flour, tapping out any excess. This simple step helps the cake release easily and keeps the texture tender.

Two 4-inch pans work beautifully for a small family birthday celebration, though cupcakes are another easy option.

Mix the Dry Ingredients

In a large bowl, whisk together:

  • whole wheat flour
  • baking powder
  • baking soda
  • cinnamon
  • salt

This gentle spice blend adds warmth that makes the cake feel like cozy homemade comfort baking.

Set the bowl aside while preparing the wet ingredients.

Blend the Wet Ingredients

Place the banana, applesauce, milk, and maple syrup in a blender.

Blend until completely smooth. The banana and applesauce create natural sweetness and moisture, making this homemade cake recipe feel softer and more nourishing.

Pour the mixture into a bowl or measuring cup.

Whisk in the egg and vanilla extract until smooth and creamy.

Combine the Batter

Pour the wet mixture into the bowl with the dry ingredients.

Using a spatula or spoon, gently mix until just combined.

Try not to overmix. A few small streaks of flour are perfectly fine and actually help keep the cake light and tender.

This small step keeps the homemade baking texture soft and fluffy.

Bake the Cake

Divide the batter evenly between the prepared cake pans.

The pans should be just slightly more than half full.

Bake for 20–23 minutes, or until a toothpick inserted into the center comes out clean.

If making cupcakes, bake for 14–16 minutes.

Let the cakes cool in the pans for about 10 minutes, then carefully transfer them to a wire rack to cool completely before frosting.

Cooling fully keeps the frosting smooth and helps the layers stay neat for your family birthday cake moment.

Make the White Whipped Cream Frosting

Using an electric mixer, beat the heavy whipping cream until it becomes soft and fluffy whipped cream.

The result is a light, creamy frosting that pairs beautifully with the soft cake.

For a double-layer cake:

Spread a spoonful of frosting on the top of the first cake layer.

Place the second layer on top and gently spread frosting over the top and down the sides using an offset spatula.

This simple finish keeps the cake feeling soft, cozy, and homemade.

Make the Purple Blueberry Frosting

For a naturally colorful option, start by placing the frozen blueberries and water in a small saucepan.

Heat over medium-low, stirring often, until the blueberries soften and burst — about 8 minutes.

Allow the mixture to cool slightly.

Transfer it to a blender and blend until smooth.

Let the blueberry puree cool completely before adding it to the whipped cream.

Beat the heavy cream until soft peaks form, then gently fold in the blueberry mixture.

This creates a beautiful purple frosting with natural sweetness, perfect for a playful first birthday cake.

Frost the cake using the same layering method.

Cozy Tips & Serving Ideas

Make-Ahead Friendly: Bake the cake layers a day in advance and store them in the refrigerator for an easy celebration setup.

Naturally Sweet Option: The banana and applesauce provide gentle sweetness, creating a more balanced homemade birthday treat.

Gluten-Free Adjustment: A good 1-to-1 gluten-free flour blend can work well in place of whole wheat flour.

Family Dinner Dessert Idea: This small cake is perfect for a cozy family birthday dinner or intimate celebration.

Cupcake Version: For busy party prep, bake cupcakes for easier serving at gatherings.
