Here’s the dilemma. You want your baby to have an adorable, memorable time squishing his chubby little hands in a colorful smash cake on his first birthday.

But you’re not crazy about the idea of your tiny precious human gorging himself on a cake that has enough sugar, butter, and artificial colors in it to give even YOU a tummy ache.

Good thing you can have it all! This small, simple homemade cake is moist, light, tasty, and irresistible to smash. And it’s made from simple whole food ingredients like fruit, whole milk, and whole grain flour.

You won’t find any added sugars or oils in this cake, either. It’s the perfect recipe to help you keep fun traditions while avoiding ingredients you’re not ready for your baby to taste yet.

How to Make Baby’s First Birthday Cake

This cake is easy to make! The basic concept: mix the wet ingredients in one bowl, the dry ingredients in another, then stir them all together to finish the batter.

There’s one unconventional ingredient in this recipe, and that’s the fruit puree. Use your food processor to blend a banana with half a cup of sliced peaches. It’s OK to use frozen (and thawed) peaches here. Fresh also works, and you can leave the skin on if you like. Just make sure you blend it well.

When it comes to the size and shape of your cake, you’ve got options. We used two six-inch diameter pans to make a mini layer cake. But you can also pour the batter into a standard-sized cupcake tin to make cupcakes.

Keep in mind that the batter is for a baby-sized cake. So the amount of batter you get with the recipe will only fill half a standard-sized muffin tin. You should double the recipe if you want to make a full-sized sheet of cupcakes.

Bake the cake until a toothpick comes out clean from the center, than cool on a rack.

The frosting is simply whipped cream! Use a stand-mixer or hand beaters to whip heavy cream, then spread it onto the cake.

There! So Pretty.

Tips for Decorating Baby’s First Birthday Cake

Now’s the fun part. Indulge your creative impulses! Here are a few fresh and fun ideas for dressing up your baby’s first birthday cake:

  • Decorate with fresh berries. Cut strawberries, blueberries, raspberries, or blackberries make this cake naturally beautiful.
  • Get a “1” candle, or another themed cake topper. Is your party nautical? Elmo-themed? Unicorns? Dinosaurs? Check Amazon for cake toppers that match your baby’s bash.
  • Add 1-2 teaspoons of corn starch to the whipped cream frosting if you’re assembling your cake ahead. This prevents the frosting from melting and losing its shape while you’re waiting to serve it.
  • Put a dash of dye-free sprinkles onto baby’s cake. We like the pretty pastels of this brand.
