INGREDIENTS IN KETO VANILLA CAKE
Almond Flour - Use a fine ground almond flour for cake recipes. You'll get the best light and fluffy texture that way.
Coconut Flour - The combination of two types of flours makes for the best texture. I've tested this specific blend to get the perfect tender crumb.
Powdered Erythritol - This is my favorite sweetener for baking with. Use the powdered form of erythritol for best results.
Baking Powder - Baking powder helps the cake rise in the oven.
Salt - Just a bit to balance the sweetness.
Eggs - Leave your eggs on the counter for at least 30 minutes to get them to room temperature.
Buttermilk - this cultured milk adds a specific tenderness and lightness to the cake, but whole milk can be substituted.
Unsalted Butter - Melt your butter and then allow it to cool before mixing. Making a keto cake with butter gives you an extra rich and decadent experience.
Vanilla Extract - Use your best quality vanilla extract for this cake.

HOW TO MAKE KETO VANILLA CAKE
A keto vanilla cake is really simple to make!

- In a separate bowl, whisk together the almond flour, coconut flour, powdered erythritol, baking powder, and salt.

- Divide the batter evenly between two prepared baking pans, then bake as directed in the recipe.
These numbered steps match the numbered photos above and are for illustration purposes. For the complete list of ingredients and instructions, please see the recipe below.

HOW TO SERVE KETO VANILLA CAKE
You can serve this cake "naked" with some berries and call it a delicious day, but for a really decadent sugar free vanilla cake, make a keto vanilla buttercream to fill and top a keto layer cake.
The recipe for my sugar free buttercream is in the recipe card below. It comes together in just minutes with four ingredients, including butter and powdered sweetener. You can color this keto cake frosting using food dyes or natural colors for a beautiful keto birthday cake.
Sugar free sprinkles would be so fun to add to this cake as well.
Alternately, you may want to serve this low carb vanilla cake with Keto Whipped Cream or Keto Chocolate Frosting.
TIPS FOR MAKING AN ALMOND FLOUR KETO CAKE
If you haven't done much Keto baking, it can be helpful to learn about using almond flour in baking recipes. We use almond flour as a low carb substitute for wheat flour, but it acts slightly differently than wheat flour in cake recipes.
- First, if you are storing your almond flour in the fridge or freezer, let it come to room temperature before using in your recipes.
- When measuring almond flour, always use a spoon to fill your measuring cups rather than scooping down into your flour container. This will ensure that you aren't measuring too much flour.
- Almond flour (and coconut flour) will absorb wet ingredients differently than wheat flour. You may notice that your batter is thicker than you'd expect it to be for a cake recipe. This is normal.

HOW TO STORE SUGAR FREE VANILLA CAKE
Without icing, you can store the baked cake in the refrigerator or at room temperature in a sealed container for up to 3 days before serving.
You can freeze unfrosted cake layers, well wrapped in plastic, for up to 3 months. Allow to thaw before decorating.
HOW TO ASSEMBLE A KETO LAYER CAKE
You can make a cake as beautiful as the one in these photos. It's not hard! Just follow these tips.
- Bake your cakes, and allow them to cool completely before attempting to frost and stack them.
- Find a large plate or a cake turntable to work on. Add a tablespoon of frosting to the middle of the plate, then place the first layer on top of that. The frosting works like glue to keep the cake in place.
- Next, add about a cup of buttercream frosting to the top of that first cake layer. Spread it evenly.
- Finally, add the second layer of cake. Here I like to turn the cake upside down so that the flat bottom of the cake is now the top.
- To complete the layer cake, use the rest of your frosting to cover the top and sides of the cake. Decorate as desired.
SUBSTITUTIONS IN KETO VANILLA CAKE
I've tested this recipe as written here and made lots of changes as I tested to make sure that I loved the outcome.
For best keto cake results, I don't suggest making any substitutions. But if you do decide to try something different, let me know how it turned out for you.
Sweetener Substitutions: I use powdered erythritol in most of my keto baking recipes, including keto cake. I find it easy to work with and the flavor and sweetness level is right where I want it to be. I've had good results using either plain powdered erythritol or Lankanto, which is a combination of erythritol and monk fruit. I don't recommend trying to use any liquid sweeteners, but other granulated sweeteners should be able to be used instead.
Flour Substitutions: The best combination for making keto cakes is the ratio of almond flour to coconut flour that I've used in this keto vanilla cake recipe. I can't give you any other options that work as well because I haven't found one yet!
If you're looking for a way to use up those last few pieces of keto vanilla cake, consider making birthday cake ice cream with it, or create a low carb blueberry trifle.

Notes
- Allow all ingredients to come to room temperature before mixing, especially the eggs and almond flour.
