Ingredients for the Best Keto Birthday Cake

All the ingredients in this gluten-free yellow cake are easy to find at your local grocery store or you can order them online. I’m sure that if you made any of my other recipes, you’re familiar with my easy keto dessert recipes that are super easy to make and super delicious.

what ingredients to use to make keto cake

You’ll be impressed by how few ingredients are needed for such a fancy cake:

  • Keto Flours – I always use a mix of almond flour and coconut flour as they complement each other and deliver that fluffy and airy texture. I suggest using both of these flour without trying to make any substitution. Choose superfine blanched almond flour to make this almond flour vanilla cake. If possible, sift the flours before use.
  • Unsalted Butter – Make sure to use unsalted butter and add only a dash of salt as this is a low carb dessert, and salted butter would overpower the sweet taste. If you’re looking for a dairy-free keto cake replace butter with melted coconut oil or avocado oil.
  • Sweetener – I used Erythritol in this cake, but Monk Fruit sweetener or Allulose work as well. These are my favorite keto sweeteners that don’t have any aftertaste and taste similar to sugar.
  • Eggs – Use room temperature large eggs
  • Vanilla Extract – I highly recommend using high-quality pure vanilla extract to make this cake taste heavenly.
  • Baking Powder – works as a leavener and helps the cake rise and become fluffy.

How to Make this Keto Vanilla Cake?

The ingredients in this gluten-free birthday cake are enough for baking 2 cake layers with an 8-inch diameter. You can use a 9-inch cake pan as well, but the cake will be slightly thinner. 

keto birthday cake step by step instructions
  1. Preheat the oven and line the pans with parchment paper, and grease the sides well.
  2. To make the cake: Cream together the eggs with the butter, then add eggs one at a time. Incorporate the rest of the ingredients until a smooth batter forms. Don’t over mix! The keto batter for this cake is slightly thick and not runny. It hardens as it bakes, and the coconut flour absorbs the liquid in the eggs. 
  3. Bake the cake in the preheated oven for about 20-25 minutes until the edges look golden brown and the top is set. For a moist cake, don’t overbake the cake, or it becomes super dry and crumbly.
  4. Once baked, remove from the oven and allow to completely cool.
  5. Meanwhile, make the keto frosting by simply combining room temperature butter, cream cheese, sweetener, and vanilla extract until fluffy and creamy. This keto vanilla frosting is almost zero carbs per serving.
  6. Decorate the cake – Spread the frosting evenly on the cake, decorate with a sprinkle, and let the party begin. Enjoy a slice or more with your loved ones.

Tips for the Best Keto Vanilla Cake

  • If you prefer to make a single-layer cake, have the recipe and use only one pan. 
  • Use a hand mixer to cream the sweetener and butter. A whisk or a rubber spatula won’t deliver the same results.
  • Sift the flours for the fluffiest texture.
  • Use a super fine blanched almond flour that doesn’t have any weird smell. If your almond flour smells or tastes odd, it might be rancid and ruin the whole low carb cake!

Is this a diabetic-friendly cake?

Ingredients
  

Keto Vanilla Frosting

  • 8 oz cream cheese room temperature
  • 4 oz unsalted butter softened
  • 1/2 cup powdered sweetener
  • 2 tsp vanilla

Instructions
 

  • Preheat the oven to 180°C /350°F. Line two 8-inch (20cm) cake pans with parchment paper and spray with non-stick spray.
  • Make the cake: Combine the dry ingredients: almond flour, coconut flour, baking powder, salt. Stir to break any almond flour lumps. Set aside.
  • Cream the butter and sweetener for about 3 minutes until smooth and creamy using an electric mixer.
  • Add eggs one at a time and continue mixing. Add in milk and vanilla extract. The mixture might look curdled as the liquids combine with the fat in butter.
  • Add the dry ingredients and mix until a creamy cake batter forms. Scrape the sides from time to time.
  • Evenly pour the batter into the prepared cake pans. Use a rubber spatula to smooth out the tops.
  • Bake in the preheated oven for about 20-22 minutes. To test for doneness, insert a toothpick in the center of the cake. Let the cakes cool completely in the pan.
  • Meanwhile, make the keto frosting.
  • Assemble and decorate the cake – Place one cake layer on a large serving plate and top with half of the frosting. Top with the second layer and evenly spread the remaining frosting to cover the top and sides.
  • Refrigerate for at least 1 hour before serving! Enjoy!

  1. This sounds fabulous! For cupcakes, about how long would you say to bake? Same temp? And how many will they yield?

    Thanks in advance! I’m such a newbie at baking and terrified LOL

    1. To make cupcakes you’ll need to bake for 20-25 minutes or until they are firm to touch. I’d say you can make 12 cupcakes. If you try them, let me know how they turned out!

  2. 5 stars
    It’s really good! It’s a pain to make with dropping one egg at a time and all but it is delicious. I didn’t have almond milk so I used whipping cream and added a little more so the batter would pour into the pan.

  3. 5 stars
    Cake tastes great but layers did not bake up high. Mix came out more like a loose dough than a batter

    1. What size were your pans? The cake batter can be slightly thick if you’re not using room-temperature eggs. Hope this helps.
