vegan, sugar-free, gluten-free baby first birthday cake recipe

Caleb’s first birthday, and the vegan smash cake I made for him, were a huge success!

While we’re all about giving kids the freedom to enjoy sweets and treats, I didn’t think that his first birthday was the time to give him a sugar overdose. Especially with all of the other excitement and stimuli that day!

Instead of making the day a total sugar bomb, I decided to make my own smash cake using many of the same ingredients he’s used to, and enjoys, on a regular basis.

For instance, bananas, strawberries, cashews, dates, and non-dairy milk are things that Caleb eats often and enjoys. As it turns out, they also make a really nice contribution to baby’s first birthday cake.

While this came out to be more of a muffin or bread texture than a cake, he didn’t know the difference. He wolfed it down with utter joy and I may have stolen a few bites too.

Why A Healthy Smash Cake?

Major health organizations, like the American Heart Association, recommend waiting until at least two years of age to introduce added sugar to kids. Even after age two, it’s best to limit sugar intake to less than six teaspoons (or 25 grams) per day.

Why? Research shows that eating large amounts of added sugar is linked to a heightened risk for issues like high blood pressure, obesity, heart disease, and diabetes.

Since early childhood is a time when numerous health habits begin to form, we can probably all agree that this isn’t the best time to make added sugars a regular part of our kid’s diet.

That’s why we love this healthy smash cake.

So, if you’re looking for a healthy alternative for your baby’s first birthday cake, we highly recommend this recipe. It’s vegan, gluten-free, and sugar-free… as well as kid-tested and delicious!

  • 1 3/4 cups oat flour
  • 2 tsp baking powder
  • 2 each bananas, mashed
  • 1 cup strawberries, sliced
  • 1 Tbsp vanilla
  • 3/4 cup milk (we like soy, almond, or cashew)


  • 1 1/2 cups cashews (soaked for at least 2 hours)
  • 1 Tbsp lemon juice
  • 1 tsp vanilla
  • 1/2 cup milk

To make the cake:

  • In a large bowl combine oat flour and baking powder.
  • In another bowl, combine mashed bananas, strawberries, vanilla, and milk.
  • Mix wet with dry ingredients.
  • Pour into 3 x 4-6 inch round, greased cake pans and bake at 350 degrees for 20-25 minutes.
  • While the cake bakes, make your frosting!

To make the frosting:

  • In a high-powered blender, combine cashews, lemon juice, vanilla, milk, and dates until smooth.
  • Let the frosting chill in the refrigerator until you’re ready to use.
  • Let the cake completely cool, then stack the layers adding frosting in between.


For best results, frost the cake right before serving or keeping the cake in the fridge until serving to keep the frosting hard.

    This post and recipe was shared with me on Facebook. The cake is adorable.. I am being recruited to “attempt” to make this for my grand-daughters first birthday.. How did you make the giraffe and tree?

    • alexwhitney on June 10, 2019 at 11:40 pm

      Those were purchased!

  4. Ln on June 25, 2019 at 1:49 am

    I only have a 9 inch pan .. will this change baking time ?

    • alexwhitney on July 15, 2019 at 2:22 pm

      Yes, check it earlier and see when it’s done.

    This cake is amazing. I just did a test before my daughter’s first birthday and I couldn’t believe the texture of the frosting! If I’d like it a bit sweeter so you think it’d be fine to add 2 more dates to the frosting and a some to the cake too?

    • alexwhitney on July 15, 2019 at 2:21 pm

      So glad you liked it!

  6. P on August 23, 2019 at 12:31 pm

    First time making a vegan cake. Will it be okay to make ahead of the birthday?

    • alexwhitney on August 27, 2019 at 4:49 pm

      Yes! Shouldn’t be a problem. Freeze, then defrost before frosting!

  7. Eleonora on September 20, 2019 at 1:43 pm

    Lovely cake!
    I want to make it for my little girl’s 1st birthday.

    Is the giraffe edible? And where did you buy it from?

    Thanks a lot

    • alexwhitney on September 23, 2019 at 4:09 pm

    Hi! Just wondering if there are any recipe options that you know of for a baby with cashew and peanut allergy! Thank you!

    I have just tried to make this cake for my grandsons 1st birthday. Unfortunately the cake didn’t look properly or rise. Is this 1 and 3/4 of flour or 1 x a 3/4 cup of flour?

  10. Gözde on November 16, 2019 at 10:20 pm

    How did u manage to do giraffe and number 1 ?

    • alexwhitney on November 18, 2019 at 5:25 pm
