If you’re looking for a special first birthday cake—or second, or third birthday cake!—you’ll love this Honey Oat Smash Cake with Greek Yogurt Frosting. It’s moist, flavorful, and super delicious, but it happens to be made without refined sugar or gluten, so it’s a little healthier for your birthday girl or boy to dig into. And, it’s easy to make it look stunning, without the need for any cake decorating skills!
Healthy First Birthday Cake
This smash cake recipe comes from my friend Sarah of Punctuated with Food. She made it for her youngest daughter Ruby when she turned one and has been making it ever since for other occasions too!
“While we’re not particularly rigid about limiting sweets, especially when it comes to special occasions, I instinctively look for ways to keep treats as wholesome as possible. When I stick to that philosophy, I find we enjoy celebrations even more, having enjoyed something special to eat without crashing too hard in the minutes and hours that follow.”
1st Birthday Smash Cake Recipe
This healthy first birthday cake is made with whole grains and natural sweeteners, but it is joyfully gratifying to eat for both babies and their parents. The texture is light and delicate but the flavors are bold —hearty oat, floral honey, and tangy yogurt. It’s lovely even without the fruit, though I think the fresh berries make it extra special!
Gluten-Free Smash Cake
“And speaking of those berries, they resulted in an unintended but possibly appealing outcome in a smash cake situation. Turns out, your little one might be too involved with picking off and eating the sweet berries to get too far into the cake itself. This means the adults might even have a chance to enjoy the cake too!”
The oat flour in the smash cake recipe is made from finely grinding rolled oats in a food processor or blender. You can buy oat flour if you’d like to skip a step. And if you need the cake to be gluten-free, simply buy certified gluten-free oats.
This fresh smash cake has a base of rolled oats and is simply decorated—so your little one can dig right into the deliciousness!
- 1 1/2 cups oat flour
- 1 teaspoon baking soda
- 1/4 teaspoon salt
- 6 tablespoons unsalted butter, melted and slightly cooled
- 1/2 cup honey
- 2 eggs, lightly beaten
- 1 teaspoon vanilla extract
- 1 recipe Greek Yogurt Frosting
- 1 cup fresh berries, to garnish
- Preheat the oven to 350 degrees F. Grease three 4-inch cake pans (I have only one 4-inch pan, so I bake one at a time.), and coat lightly with flour, tapping out any excess. In a medium bowl, whisk together the flour, baking soda, and salt.
- In a separate medium bowl, whisk together the melted butter, honey, eggs, and vanilla until smooth. Add the flour mixture and stir until just combined.
- Divide the batter evenly between prepared cake pans (or pour 1/3 of the batter into your single pan, bake, and repeat twice to bake your three layers). Bake until a toothpick inserted in the center of the cake comes out clean, about 20 minutes. Carefully turn cakes out onto a cooling rack until room temperature and fully cooled.
- Place the first cake layer on your serving plate with about 1/3 cup of frosting or plain yogurt, spreading it in an even layer just past the edges. Add the second, repeat with frosting, and then repeat with the third cake . Use an offset spatula or knife to scrape off the frosting overhang for a “naked” cake look, or use additional frosting to coat the entire cake. Top with berries and store in the fridge until 30-60 minutes before ready to serve. Let the birthday kiddo dig in!
Greek Yogurt Frosting
Strain 1 cup whole milk yogurt overnight in the fridge in a sieve lined with a double layer of cheesecloth, with a bowl underneath to catch the liquid. (Or use a very thick yogurt like Siggi’s.) The next day, use a spatula to place yogurt into a medium bowl. Stir in the honey. Refrigerate until ready to use.
Note: With the additional straining, this frosting is piping consistency, and you can add a drop or two of food coloring if you’d like. See example of piped Greek yogurt frosting here.
