17 Best Sugar-Free Cakes

I have a list of incredible sugar-free cakes that’ll let just about anyone feel a bit decadent without breaking their diets or shooting up their blood sugar levels.

There are plenty of people out there who’d swear that dessert is the best part of any meal, but unfortunately, due to health and dietary restrictions, not everyone gets to enjoy it.

However, being on the ketogenic diet or having diabetes shouldn’t prevent you from enjoying a delicious birthday cake, some yummy muffins, or sweet and tangy holiday treats. 

And those are precisely the kinds of things you’ll find on this list.

From birthday cake and coffee cake muffins to the fruit cake and pumpkin cheesecake, this roundup has it all. 

So get ready to enjoy some truly delectable desserts without all the added sugar and carbs. 

Sugar-Free Cake Recipes for Diabetics, Keto, and More

1. Diabetic Birthday Cake

What if I told you that you could whip up two layers of light and fluffy vanilla cake, topped in creamy chocolate frosting, and keep the sugar count to a mere 2 grams per serving?

It’s true, and you won’t even need any hard-to-find ingredients to do it, just standard baking ingredients. 

Simply substitute Splenda for sugar and make your frosting with sugar-free whipped topping, a sugar-free packet of chocolate fudge instant pudding mix, and skim milk. 

And voila! You’ll have an insanely good birthday cake with only 2 grams of sugar! 

2. Keto Chocolate Cake

Despite its low-carb status (2.7 net carbs), this keto chocolate cake is 100% chocolatey goodness through and through. 

It uses fewer than ten ingredients and has an insane amount of rich cocoa flavor.

Plus, a little tweaking on the eggs and substitution of water for milk makes it vegan-friendly as well. 

3. Keto Death by Chocolate Cake

Here’s another keto death by chocolate cake that’s even more indulgent than the last. 

It’s three layers of incredibly sweet chocolate, separated by velvety smooth, chocolate cream cheese frosting.

Top it with even more chocolate chips, and drizzle it with melted chocolate.

It won’t actually kill you – and with only five net carbs per serving, it shouldn’t – but it certainly tastes good enough to make you believe it could.

4. Lemon Pound Cake

If you’re looking for something with a bit more tartness and tanginess, give this lemon pound cake a try.

It’s spongy, lemon-flavored, and has a crunchy poppyseed surprise inside.

The sweet and sticky lemon glaze gives it a bit of extra zestiness. 

5. Coffee Cake Muffins

Whether you’re looking for something sweet, cinnamony, and crumbly for breakfast, lunch, or dessert, these coffee cake muffins are just the thing. 

They’re fluffy but dense and have a fantastic buttery taste that’ll make you want to eat them for every meal of the day.

6. Bundt Cake

This tasty treat looks, feels, and almost tastes like any other chocolate bundt cake you’ve tried. The difference is that it is sugar-free and low-carb. 

It also takes only 5 minutes of prep time and another 40 or so to bake. The rich chocolate glaze on top adds extra decadence and looks lovely.

7. 3-Ingredient Christmas Cake (Fruit Cake)

Of all the desserts on this list, this one is the most impressive and unique because you can make it with only three ingredients: dried mixed fruit, iced coffee, and self-rising flour.

That’s all it takes. There’s no sugar, eggs, baking powder, or other standard baking ingredients – just those three things.

It’s moist, crumbly, and full of fruity flavor. 

8. Angel Food Cake

With less than one gram of sugar and only 5.6 total carbs per serving, this spongy, vanilla-flavored angel food cake requires only six ingredients. 

With nothing more than egg whites, cream of tartar, powdered monk fruit, almond flour, coconut flour, and vanilla extract, you can have it ready in just a little over an hour. 

Top it with whipped cream, berries, icing, or whatever else you like on your cakes. It’s unbelievably simple and scrumptious. 

9. Sugar-Free Cheesecake

Not only is this yummy cheesecake sugar-free and keto-friendly, but it’s also no-bake and requires only 15 minutes of hands-on prep time.

Then, you’ll simply stick it in the fridge and let it chill for several hours.

It’s sweet and tangy, and you can eat it plain or topped with extra cream and your favorite berries. 

10. Keto Marble Cake

Marble cake is gorgeous, super tasty, and gives you the best of both chocolate and vanilla worlds. It’s also keto-friendly and gluten-free. 

You can make it with fewer than ten ingredients in just a touch over an hour, and only 15 minutes of that is active preparation time. 

And if you’re worried about getting the attractive swirl, don’t be; it’s remarkably simple.

It’s just a matter of adding the two batters and swirling them with a knife or spatula. 

11. Blueberry Breakfast Cake

All you’ll need to make this moist, pillowy soft blueberry breakfast cake is almond flour, cinnamon, baking powder, eggs, coconut oil, vanilla extract, blueberries, and cream cheese frosting.

You’ll also need your no-carb/low-carb sweetener of choice. I like to use monk fruit sweetener, but Splenda or erythritol are okay, too. 

Just don’t be surprised when there’s a tart blueberry explosion in your mouth. 

12. Sugar-Free Lemon Blueberry Cake

Here’s another great blueberry cake recipe, but this one is even more sour and tangy, thanks to the addition of lemon juice and lemon zest. 

The cake layer is light and fluffy, and the thick layer of buttercream icing on top is insanely rich and thick.

Luckily, the tartness helps cut down a bit on the sugary sweetness. 

13. Keto Blueberry Mug Cake

If you’ve never had a mug cake – an individualized serving size cake you make in a mug in your microwave – then you’re in for a real treat. 

It takes about 5 minutes to prepare this tangy blueberry cake and another 1 minute to cook it. Yes, that’s not a typo—1 minute. 

Best of all, it may be small and easy to make, but it tastes like the real thing. 

14. Keto Pumpkin Cheesecake

If the sight of all that orange creaminess doesn’t make your mouth water, then you and I are not the same because that slice of cheesecake looks heavenly to me. 

It’s silky smooth, features your favorite fall spices, and takes only 20 minutes to make. And again, it’s pumpkin cheesecake! That’s really all you need to know. 

15. Keto Cinnamon Mug Cake

If you’re looking for a mug cake that’s more sweet and rich and less tart and tangy, then try this keto cinnamon mug cake instead. 

It still has the same 6-minute prep and cook time, but the taste is much warmer and more decadent.

To make it, you’ll need an egg, coconut oil, monk fruit, almond flour, baking soda, ground cinnamon, and peanut butter. 

It’s beautiful and tasty, so what’s not to love?

16. Easy Keto Butter Cake Recipe

Butter cake may not sound like much, but just imagine the most amazing, softest, and butteriest homemade cake layer your grandmother ever made. 

Remember how it just fell apart in your hands because you couldn’t wait for it to cool down before you bit into it?

Remember how it practically melted on your tongue?

Yeah. That’s this cake; only this one is 100% keto-friendly. You’re welcome.

17. Keto Vanilla Cake

All you’ll need for this simple vanilla cake layer is olive oil, your sweetener of choice, almond meal, eggs, sour cream, vanilla extract, and baking powder. 

The great thing about this one is that it also gives you a bright and zesty lemon buttercream frosting recipe. If you like lemon, I highly recommend making it. 

However, if that isn’t your thing, you can top it with any sugar-free or keto-friendly frosting you can find at the store or use any of the other frosting recipes you enjoyed on this list.
