The Best Sugar-Free Keto Funfetti Birthday Cake
Do you recall the feeling of going to a party but being unable to eat the coveted birthday cake? Just thinking about it makes you sad. After all, the main reason why you go to a birthday party is to eat the cake (and don’t you dare deny it!).
While you can’t control what other birthday celebrants choose to serve at their parties, you can at yours. And if you want everyone to enjoy your birthday cake, regardless of if they are low carb, you know that a regular birthday cake just won’t do! That’s why we’ve got you covered with our funfetti cake recipe.
This delightful cake starts with a base made from a blend of almond flour, coconut flour, milk and vanilla extract a touch of xanthan gum for that perfect texture. We’ve sweetened it with a keto sugar alternative that won’t spike your blood sugar levels. The addition of unsweetened coconut adds a tropical twist and enhances the cake’s moisture. If all this sounds yummy, let’s get started with the baking, shall we?

Tools you'll need on hand:
- Cake pans: this is where we'll be pouring our cake batter before we put it into the oven for baking. For this recipe, we'll be using two 8-inch diameter cake pans as we'll be making a two-layer keto birthday cake. If you prefer to use a larger pan, you'll either have to make a single-layer cake or increase the proportions of the ingredients in this recipe.
- Parchment paper: you'll be using this to prevent the cake batter from sticking to the cake pans. This will make it easier to remove the cakes from the pans when they are finished baking.
- Mixing bowl(s): this is where we'll be mixing our wet and dry ingredients to create the cake batter. You may opt to use the same bowl or another one to create the buttercream frosting.
- Liquid food coloring: we'll use this to add color to our coconut "sprinkles." Have as many different colors as you want. More colors, more fun!
- Make sure to taste the cake batter first before baking and adjust the sweetness to your preference. Note that the sweetness may slightly decrease during the baking process.
- You may use coconut milk, cashew milk, or any other keto-friendly milk instead of almond milk. Do note that it may change the flavor slightly.
- Use room-temperature eggs. This will ensure that the cake batter blends beautifully. Don't use refrigerated ones, as it can result in a lumpy batter that may even require a longer bake time.
- You can do away with the coconut "sprinkles" if that isn't your thing. You may top your keto birthday cake with other keto-friendly options, such as pecans or walnuts.
- If you want more control over the cake's flavor, you may use unsalted butter.
Frequently Asked Questions
Almond Flour: Another way to cut carbs is to get rid of flour-based food. Even substituting to wheat flour has just too many carbs in it to be keto or low-carb-friendly. So, instead of regular flour, we would use almond flour– this keto-friendly flour substitute is extremely low in carbs and healthy fats. This makes it perfect for our funfetti keto birthday cake recipe .
Use blanched almond flour (or superfine almond flour) as it has a finer and lighter texture compared to regular almond flour. This will help in giving our birthday cake a lighter-colored appearance and less dense texture.
Coconut Flour: To add more taste and thickness to our keto funfetti cake, we’ll be mixing in coconut flour. It’s another keto-friendly flour substitute that also makes an excellent thickener. It will add coconut flavor to our birthday cake, which should go well with our coconut “sprinkles.”
No, we do not. The sprinkles in a regular birthday cake are typically made of hardened sugar. As we can’t have that on our sugar-free birthday cake, this recipe utilized unsweetened shredded coconut and some food coloring to create our mock sprinkles.
Note that it’s important to use unsweetened shredded coconut. This is because sweetened coconut contains sugar, which makes it non-keto and most certainly exceeds your macros.
Yes, you can! You just have to increase the proportions of the ingredients listed in the recipe. For example, if you want to have four cake layers, you just need to double the recipe. Just adjust the proportion for any additional cake layers that you want.
Technically, you can. You can use vegan butter with no issues. However, it’s hard to make a cake without eggs and have it retain the same texture. You can use an egg substitute, but the cake will not be as fluffy or as moist. It may be denser too. If you don’t mind that, sure, go ahead and use a pre-formulated egg substitute.
The chances of having leftovers are very low, but just in case you need to store any, you can store them in your refrigerator. Put any leftover cake in an airtight container and put it in the fridge. It will stay good for up to 4 days.
If you need to store it for far longer, you can put it in the freezer. It should be good for up to 6 months. Defrost the cake overnight in the fridge before serving it. That said, I am not a fan of defrosted cake so I would not suggest doing this.
You likely stirred your batter way too much. To avoid this from happening, make sure to mix together your wet ingredients first. When they’re already well mixed, that’s when you add in the dry ingredients. Mix them together until everything is well mixed but still slightly lumpy. Remember not to overdo it!
Your cake is probably still undercooked. You need to allow enough baking time for your cake to rise and set properly. Pop it in the oven again and let it bake some more.
Certainly, and I hope this keto cake recipe showed you how possible and easy it was.
To substitute sugar as the sweetener to our keto funfetti birthday cake, we used the keto-friendly Lakanto Monk Fruit Sweetener. It’s a great sugar substitute for keto cake recipes as it has no aftertaste, has a zero glycemic index, and has zero additives. What’s more, it has a 1:1 ratio to sugar, making it easier to convert traditional dessert recipes into keto-friendly ones.
For our buttercream frosting, we also used Lankanto Powdered Monk Fruit Sweetener as our sugar substitute. This keto-friendly sugar substitute has all of the same qualities as the granulated version, only in powdered form. With this, we were able to get a keto frosting that was not grainy.
You cannot eat just any birthday cake on a keto diet, as traditional birthday cakes are typically high in carbohydrates and sugar, making them unsuitable for a keto diet, let alone a low-carb diet. When following a keto diet, it’s important to limit your carbohydrate intake and focus on consuming high amounts of healthy fats and moderate amounts of protein. Most cakes are neither of these.
However, this Funfetti keto cake recipe is specifically crafted to be low in carbohydrates and sugar, making it a suitable option for those following a keto lifestyle. Using almond flour and coconut flour instead of traditional wheat flour and incorporating keto-friendly sweeteners, you can enjoy a delicious birthday cake while staying within your keto dietary guidelines.
