These keto cupcakes are so moist and fluffy, you won’t believe that they are low carb! Made with coconut flour and naturally sweetened, they are perfect with a sugar free frosting! 2 grams ner carbs per cupcake.

When it comes to keto desserts, there is nothing better than chocolate cake, no bake cheesecake, and fluffy keto cupcakes

These keto vanilla cupcakes were inspired by my recipe for a keto vanilla birthday cake. As nice as making a full cake is, there is something special about cupcakes.

Now, don’t let the low carb ingredients put you off making them. They are just as fluffy as any good cupcake out there. They also have the most delicious vanilla flavor, and we can’t forget the keto vanilla frosting on top! 

Perfect for serve at parties, celebrations, events, or when you want a perfectly portioned dessert, these sugar free cupcakes are a winner!

How do you make keto cupcakes

You only need 7 main ingredients and no fancy gadgets to make fluffy vanilla cupcakes! 

keto cupcake ingredients

The Ingredients

  • Butter– Room temperature butter, and unsalted. 
  • Granulated sweetener– Either erythritol or monk fruit sweetener can be used. I prefer monk fruit sweetener, as it doesn’t tend to have the sometimes grainy texture. 
  • Salt– Brings out the sweetness of the cupcakes!
  • Vanilla extract– A must for any cake or baked good recipe! 
  • Eggs– Room temperature eggs. If you’d like to make it without eggs, you can try using an egg replacer. 
  • Milk– Any milk will work. I used unsweetened coconut milk, and it didn’t have any coconut flavor! 
  • Coconut flour– A low carb and grain free flour, the coconut flour gives these cupcakes the incredibly fluffy texture. If your coconut flour has clumps, sift it before adding it to the batter. 
  • Baking powder– Gives the cupcakes some rise and
  • Vanilla frosting– A simple vanilla buttercream frosting made with homemade keto powdered sugar.

The Instructions

Start by beating together your butter and sweetener, before adding the rest of your wet ingredients. Fold through your dry ingredients and mix until just combined. Distribute the cupcake batter amongst a greased muffin tin. Bake the cupcakes at 180C/350F for 18-20 minutes, or until a skewer comes out clean from the center. Remove from the oven and let cool in the pan for 10 minutes, before carefully transferring to a wire rack to cool completely. Once cool, frost the cupcakes.


Can I make these without eggs? 

I often get asked for vegan subs for many of my keto recipes. I tested these cupcakes with chia eggs and flax eggs and they did NOT come out well at all. They just wouldn’t hold their shape and lost their fluffy and cakey texture. 

If you want to make these vegan, use a pre-formulated egg replacer, like Bob’s Egg Replacer. Use the equivalent of 4 eggs.

Tips for perfect keto cupcakes

  • You cannot substitute the coconut flour for another flour. It will not bake correctly and will likely crumble. If you’d like a muffin recipe without coconut flour, try chocolate muffins.
  • Do not overmix the batter, to keep the fluffy and light texture. Mix until all the coconut flour has been folded through.
  • Avoid overbaking the cupcake,  as they continue to cook while cooling down.
  • Always use cupcake liners, as even non-stick muffin tins are prone to sticking. Also, even though the cupcake liners *should* not stick, I still lightly spritz each one with cooking spray, just to be safe.

Storing and Freezing Cupcakes

  • To store: Leftover cupcakes will keep well at room temperature, in a sealed container. If you don’t use frosting, you can even cover the cupcakes with a paper towel, to keep them extra fluffy and moist. You can also refrigerate them to keep longer. 
  • To freeze: Freeze leftover cupcakes in a ziplock bag and store in the freezer for up to 6 months. Thaw overnight in the refrigerator or at room temperature.

Keto Cupcake Flavors

  • Chocolate Cupcakes– Add 1/2 cup cocoa powder to the batter and increase the milk by 2-4 tablespoons, or as needed. Top with a keto chocolate frosting.
  • Red Velvet Cupcakes– Add a few drops of red food coloring to the batter, and top with a keto cream cheese frosting.
  • Chocolate Chip Cupcakes– Fold through 1/2- 1 cup of keto chocolate chips to the batter. Reserve a handful to top the cupcakes with. 
  • Lemon Cupcakes– Add 1/2 teaspoon lemon zest and 1 tablespoon of lemon juice to the batter. Add 1 tablespoon lemon juice to the cream cheese frosting.

  1. Why are the carbs on the frosting so high? Just curious when not using sugar, thought the carbs with be way down since butter and cream cheese has little or no carbs….is the sugar sub that high?? Your recipes are awesome BTW, so I want to try these, but, I’m concerned about the carbs. Thanks.

    1. Hi! Sorry, there was an error in the calculations, it changed it to 25 when it should be 2- it is 1 net carbs per half cup 🙂

  2. In your directions it says to add the salt to the wet ingredients, but in the ingredient list I can’t find how much salt to put in oh

    Thanks for this recipe! I loved that it was moist and doesn’t have an “eggy” taste despite the amount of eggs added. The coconut flour also provided a good balance by absorbing the fats from the butter. I added blueberry on some of my cupcakes and it gave another layer of flavor and texture to the cupcake, hence not requiring the frosting anymore. Loved it!

    I did not think they were going to come out as I was making them because the butter would not incorporate. I softened it before adding, but it just stayed in clumps kind of looking curdled. Followed recipe exactly. They are delicious. Made these for my birthday. They are so good, honestly, they don’t need icing. I did not have time to make the icing with recipe provided, so I bought keto organic vanilla icing. I will make these again. My goal is to make the keto birthday cake next! I am not good at baking, but your recipes allow me to be successful! They have a delicious taste, not overpowering. The texture is fluffy but holds together nicely. Ever so slight hint of coconut flour but barely detectable. I liked the flavor very much. Easy and delicious. Thank you!

  5. 5 stars
    Wow, I just made these the recipe, the cupcakes are soft and buttery I added some walnuts too. thank you so much for sharing this recipe

  6. Is it best to make these right before they will be eaten, or make the night before? The ingredients cost me a little more than usual, and I don’t want to mess them up.
