Usually, keto cake batter made with almond flour sticks a bit more to cake pans so it is very important to use a non-stick high-quality aluminized pan. It may sound expensive to invest in a high-quality pan but they last for years. The one below is in my kitchen for 7 years and none of my cakes stick to it.
I am using a 9-inch cake pan with a non-stick coating, removable sides that clamp around the base, and ridged texture at the bottom.
If your pan doesn’t have a ridged texture, your cake may stick slightly at the bottom. To prevent your keto cakes from sticking to the pan, I recommend a double-greasing method.
First, grease the whole pan, bottom, and sides, with butter or coconut oil. Then, cut out a piece of parchment paper, the same diameter as the pan, so here a 9-inch circle.
Place the piece of parchment paper at the bottom of the pan, it will stick to the pan since you grease it before. Finally, grease the whole pan again, including the paper. This 2-step greasing method will ensure that your keto cake does not stick to the pan.
Of course, no! You can simply follow the keto vanilla cake recipe and serve this delicious almond flour cake in 30 minutes. It is a good tea cake to enjoy plain or with the vanilla buttercream frosting recipe provided. I recommend making the layers and frosting though, to have a lovely light and fluffy keto birthday cake.
To make the layers of this diabetic cake, I recommend baking 2 small vanilla cakes instead of slicing a bigger one. It means you repeat the entire low-carb cake recipe 2 times.
This is the best way to create a lovely keto sponge cake with even layers and a decent cake height.
Following are my top 3 tips to make a layer cake:
I know it is tempting to double up the recipe to save time and then divide the batter in half. It would work but I don’t like this technique because it is very difficult to perfectly halve the batter. Often, you end up with a layer thicker than the other.
Never bake two cakes at the same time in your oven. It will impact the baking time too much and the baking would not be consistent. There is always one cake that burns and one that is not cooked. So take the time and bake them separately.
Your sugar-free birthday cake will come up with a small bump on top. Fully cool the cake then use a knife or a cake leveler tool to remove that bump and create 2 flat cake layers. This will make it much easier to frost them later on.
First, make sure your low-carb cake layers are cool, at room temperature to prevent the frosting from melting. Then, I recommend using a turning table and icing spatula.
Add a tablespoon of frosting in the center of the turning table and place the first cake layer on it. This frosting is not a cream cheese frosting and so will act like glue and stick the cake to the table.
Next, add 1 cup of frosting in the middle of the cake. Spread the frosting with an icing spatula turning the table at the same time to spread evenly.
The frosting will fall on the sides and that is ok. Finally, add the second cake layer and repeat this process until you have covered all the top of the cake. Use more frosting to cover the edges.
I hope you enjoyed my 36-year-old diabetic birthday cake recipe. Happy birthday to you too if you try this recipe for your birthday today.
