This Healthy Smash Cake is made simply with wholesome ingredients, like oat flour and applesauce! Perfect for your little one’s first birthday celebration.


  • 2/3 cup apple sauce
  • 3 eggs (see note for egg alternative)
  • ¾ cup oat milk
  • ½ cup coconut oil, melted and cooled (see note)
  • ⅓ cup maple syrup (optional)
  • 3 cups oat flour 
  • 1 tablespoons baking powder  


  1. Pre-heat oven to 350ºF and prepare three 6″ cake pans by cutting out three parchment paper circles to fit exactly inside the cake pan. Lightly spray the sides and bottom of the cake pans with avocado oil and place parchment paper circles inside.
  2. Add applesauce, eggs, milk, coconut oil and maple syrup to a large bowl and whisk together. Add in oat flour and baking powder and whisk until smooth.
  3. Evenly divide batter into cake pans and bake for 28-32 minutes, until the cake is puffed up all over and a toothpick inserted in the center comes out clean.
  4. Let the cakes cool in the pan for 5-10 minutes, and then remove from the pan to a cooling rack to cool completely before frosting.
  5. Frost as desired, and optionally decorate with fruit! If your cake is unsweetened, it might be a nice touch to add in some sweet fruit in between the layers of the cake.


If possible, have your eggs, milk and applesauce be as close to room temperature as possible. This is only important to prevent the coconut oil from solidifying when it hits the cold ingredients.


The coconut oil needs to slightly cool down after melting because if it is added too hot into the bowl with the other cool ingredients, it will solidify.

Need to swap out the eggs? Instead, make a flax egg with ⅓ cup ground flaxseed mixed together with 1 additional cup of milk. Let it sit for 15 minutes before adding it into the cake batter in place of eggs.

We have a whole paragraph up above with frosting suggestions. Some options would be to just use a basic buttercream. Or you could use unsweetened whipped cream. Or even coconut cream! Use what you feel comfortable serving to your baby.
