Best Keto Birthday Cake Ever – Time to Celebrate!

Keto Birthday Cake

yield: 12 SERVINGS

prep time: 15 MINUTES

cook time: 30 MINUTES

total time: 45 MINUTES

Ingredients

Cake:

Buttercream Frosting:

Directions

1

Preheat oven to 350 degrees. Spray a 9x13 baking pan with non-stick oil. Line the bottom of the pan with parchment paper. This will help the cake to pop right out of the pan after baking.

2

In a large bowl, add almond flour, coconut flour, baking powder, and salt. Whisk together to combine and set aside. *Note, be sure to spoon in the almond flour and coconut flour and level out the scoop to avoid using too much. 

3

With a hand mixer or standing mixer, cream together the granular sweetener and butter. Slowly add in eggs, heavy cream, sour cream, vanilla extract, and almond extract.

4

Add in dry ingredients while mixing on low. Make sure to scrape the side of the bowl to get all the ingredients mixed together.

5

Add batter to the baking pan, spread evenly with a spatula, and bake in a preheated oven for 30-35 minutes. If the cake starts to turn brown, place a sheet of aluminum foil over it to prevent burning.

6

Remove cake from the oven and let it cool completely before removing it from the pan.

7

Make the Buttercream Icing:

Combine butter, powdered keto sweetener, vanilla, and heavy whipping cream. Use a hand mixer and mix ingredients until you have reached a creamy frosting texture, about 3-4 minutes. If icing is too thick, you can add another teaspoon or two of heavy whipping cream, continuing to beat for another 1-2 minutes, or until you have reached your desired consistency.

8

Add cake to a cake plate or stand. Frost your cake with buttercream and top with keto-friendly sprinkles. You can also tint some of your buttercream with food coloring to pipe onto the edges of the cake. Enjoy!

Tips for making the best keto birthday cake:

    • Make sure to spray your 9×13 pan with non-stick oil to prevent the cake from sticking.
    • Place a piece of foil over the pan while baking to prevent the top of your cake from over-browning.
    • I used Lina’s keto buttercream frosting recipe to make this cake over the top delicious. Make sure to let the cake completely cool before adding the frosting.

Additional Notes

Don’t be alarmed by the high total carb count! Fiber and erythritol, the main ingredient in Swerve, do not affect blood sugar in the same way that regular carbs do, so we subtracted them from the total carb count. You’ll see that the net carbs are much lower once you remove the sugar alcohols and fiber.

Make your birthday a sweet one!

I love how easy this cake is to make and knowing that it’s sugar-free is even better. I had my boys try it out and didn’t tell them it was keto and they ate it right up! So go ahead and let the whole family have a slice and sit back and watch them fall in love with this keto birthday cake.

Here’s what my teammate Jenna had to say after making this keto sheet cake:

“This is so fun and I love that it’s low carb, I mean who doesn’t love sheet cake? The kids dug into this and didn’t once care that it was keto. They often ask me before eating anything I make these days if it’s keto or not. This has the full birthday cake experience without any of the sugar, it’s perfect!”

    I’d love if grocery stores would make this and offer the single slices like they do the sugary stuff. This looks so yummy! May have to pick up the ingredients this weekend.

    • Collin (Mrs. Hip)

      Yay! Hope you love it, Brit!

  2. Beth

    No baking powder?

    • Amber (Hip Sidekick)

      Hi Beth! Baking powder is listed above in the ingredients and the instructions. Hope that helps!
