Everyone knows that the best part of a birthday is the birthday cake! I have made this dairy free vanilla cake for countless birthdays and to be honest, no one has ever even known that its dairy free.

You can easily adapt this double layer dairy free birthday cake depending on what size of cake pans you have, and you can even pair it with a dairy free chocolate frosting instead of vanilla. It’s the same frosting I use in my dairy free chocolate cake (another birthday favorite!).

Ingredient Notes

  • Milk: I love using oat milk or soy milk, since they most closely mimic whole milk in terms of being thick and creamy.
  • Sprinkles: I suggest using long strand sprinkles and avoid nonpareil sprinkles as those will bleed in the cake batter.

Recipe Developer Expert Tips

  • I always recommend using a kitchen scale to weigh out your ingredients, especially your flour! It is so easy to add too much flour if you use measuring cups, which is going to make the cake dry and crumbly.
  • Don’t skip out on lining the bottoms of the cake pans! Otherwise, you won’t be able to get the cakes out in one piece. 
  • Always let the cake layers cool completely before you start making the frosting. Warm cake and frosting are not a good mix!

Ingredients
 

  • ½ cup (105 g) dairy free butter, softened
  • ½ cup (108 ml) oil (canola oil, vegetable oil, grapeseed oil, or sunflower oil)
  • 3 eggs
  • Tablespoon vanilla extract
  • cup (250 g) granulated sugar
  • 2⅓ cup (292 g) all-purpose flour
  • ¼ cup (25 g) cornstarch
  • teaspoon baking powder
  • ¾ teaspoon salt
  • cup (375 ml) unsweetened oat milk, (or other dairy free milk)
  • ½ cup sprinkles, (NOT non pareils)

Vanilla Buttercream

  • cup (315 g) dairy free butter, softened
  • teaspoon vanilla extract
  • ¼ teaspoon salt
  • 3-3½ cups (360 g) powdered sugar (icing sugar)
  • sprinkles (optional)

Instructions
 

  • Preheat the oven to 350°F and prepare two 8 inch round cake pans. Spray the inside with cooking spray, then cut out pieces of parchment paper so that they fit in the bottom of each pan (do not skip this step!). Set the pans aside.
  • Using a hand mixer or stand mixer with the paddle attachment, beat the butter and oil together until combined. Add in the eggs and vanilla extract.
  • Mix in the granulated sugar.
  • Add in flour, cornstarch, salt, and baking powder to a separate bowl and whisk together.
  • Alternate slowly adding in the milk and the dry ingredients. Mix until combined. Gently fold in the sprinkles.
  • Divide the cake batter between the two cake pans and bake for 24-30 minutes, or until a toothpick inserted in the middle of the cakes comes out clean.
  • Let the cakes cool in the pan for 10-15 minutes, then remove them from the pan (by running a butter knife or offset spatula around the edges and then flipping the cake upside down onto a cooling rack). While the cakes cool, make the buttercream.

Vanilla Buttercream

  • In the bowl of a mixer, beat the butter, salt, and half the powdered sugar together until combined. Add in vanilla. Slowly add in ¼ cup of powdered sugar at a time until it reaches your desired consistency. If the buttercream is too thick, you can add ½ tablespoon of milk in at a time, thinning it out as much as you'd like. If buttercream is too thin, add in more powdered sugar ¼ cup at a time.

Assembling the Cake

  • Add an even layer of buttercream between each of the completely cooled cake layers.
  • Frost the outside of the cake, scraping off the excess frosting with a bench scraper (this is called a crumb coat). Then place the cake in the freezer for 20 minutes then add another layer of frosting.
  • If you'd rather skip the crumb coat, you can simply frost the outside of the cake in one layer then decorate with sprinkles or as desired.

Notes

Parchment Lining: I highly recommend lining your cake pans with parchment paper. It’s an easy way to avoid the cake breaking when you try to remove it from the pan. To do this, trace then cut a circle in the shape of your cake pan out of the parchment paper and place it inside the pans.
Measuring Flour: Either measure your flour using a kitchen scale or use the proper scoop and level method.
Cake Pan Size: This recipe can also be made with two 9 inch round cake pans. Shorten the baking time by a few minutes.
Storage and Freezing Instructions:
The cake can be stored covered at room temperature for 3-4 days. 
You can also freeze the cake layers if you want to make this cake ahead of time. Let them cool completely, then tightly wrap each individual cake layer in parchment paper, then aluminium foil. Freeze in ziploc bags for up to 3 months, then let them thaw at room temperature.
You can store leftover buttercream in an airtight container in the freezer for up to 2 months. Thaw it in the fridge then re-whip it using a handheld or standing mixer before frosting the cakes.
