Looking for basic yellow cupcakes? These vanilla Keto Cupcakes with sour cream have only 2 net carbs each. They are great plain or with your favorite icing. I also love keto vanilla cupcakes with strawberries and whipped cream. This easy low carb cupcake recipe is low carb, keto, gluten-free, grain-free, sugar-free, and Trim Healthy Mama friendly.
Birthday season is coming to our house. It begins with my baby turning 2 on December 30th and continues with everyone else within the next 6 months. Most of my husband's family also has late winter or spring birthdays. Last week I made a batch of Magnolia Bakery's famous vanilla cupcakes to freeze for our first party. They are my favorite.
But they are not Trim Healthy Mama compatible (not even a smidge). I was strong that morning and didn't even lick the mixing spoon. I don't know if I can be that strong at the party once they are covered in buttercream icing. I knew that I needed an alternative for myself so the next day I went to work creating a keto cupcake recipe. Here are my sour cream vanilla HEALTHY cupcakes. I love keto chocolate cupcakes too but there is something about a vanilla cupcake with sweet buttercream frosting that gets me every time.
These gluten free keto cupcakes are perfect. They are very flavorful I'm thrilled to have a batch in the freezer so I don't have to miss out at all of our celebrations.
Ingredients in Keto Cupcakes
Butter - I use salted butter in my baking recipes. I think the pinch of added salt balances out the sweetness of baked goods.
Sweetener - I normally use my blend of xylitol, erythritol, and stevia but offer suggestions to alternatives in the recipe card.
Eggs - Regular large eggs are the binder in this and help the cupcakes to rise.
Vanilla Extract - Vanilla is the most common extract used in baking. It enhances the other flavors and adds a subtle sweetness.
Sour Cream - Sour cream makes these moist and tender. If necessary you can sub in plain yogurt but the carbs will be slightly higher.
Almond Flour - Almond flour has a tender flavor and texture that works well in keto desserts.
Coconut Flour - I prefer to combine coconut and almond flour together. The coconut flour balances the natural oiliness of the almond flour.
Baking Powder - Make sure to check the date on your baking powder to ensure your cupcakes rise properly.
How to make Keto Cupcakes
If you have a hand mixer or food processor it is very very easy to make cupcakes! Simply mix together a couple of ingredients. Add a couple more. Mix more. Add more. Mix. And then just scoop into cupcake liners. That's it! The prep for these takes 15 minutes tops. I think I can get them in the oven in 8 minutes if my kids aren't helping. If the little ones are helping it probably takes 30. No joke.
Step One: Cream together the butter and sweetener. Add the other wet ingredients. Mix in the dry ingredients.
Step Two: Divide the cupcake batter between a muffin pan lined with cupcakes liners.
Step Three: Bake the keto cupcakes until they are golden and firm to the touch.
Chocolate - You can add chocolate chips to the batter without needing to adjust the other ingredients or baking time. For a chocolate cake batter try my Keto Chocolate Cupcakes with keto chocolate frosting.
Without Coconut - If you want keto cupcakes without coconut flour try my keto Almond Flour Cupcakes.
Berries - You can fold a few berries into the batter without compromising the recipe.
Extracts - The easiest way to change the flavor of cakes or cupcakes is to swap out the extract. Orange extract, lemon extract, almond extract, and maple extract are good choices to easily change the flavor profile.
Can I freeze Keto Cupcakes?
Yes! These cupcakes freeze really well. I like having a batch in the freezer of a couple of favorite keto recipes so I'm not tempted by high carb baked goods. A batch of these and a batch of fudge brownies ready to go and I can resist almost anything.
To freeze I recommend wrapping each one tightly in plastic wrap. After I do that I normally just pack them into a gallon-sized storage bag.
Can I double this recipe?
This recipe makes one dozen delicious sour cream vanilla keto cupcakes. If you need more cupcakes then go ahead and double or triple this recipe.
You can also double or triple this to make a sheet cake or layer cake!
Which icing to use for keto cupcakes?
There are dozens and dozens of ways to top these. One of my absolute favorites is with chocolate frosting. You can see the chocolate frosting used for these cupcakes here.

I use this batter as the base in a few of my other healthy cupcakes. This is a great recipe to start with and then play around with the flavors and top them as desired. These are a good inspiration if you aren't sure how to top the sour cream vanilla cupcakes:
My Keto Lemon Cupcakes are pretty enough for a baby or bridal shower. They are filled with lemon curd, a fresh raspberry, and then topped with Raspberry Buttercream!
Cranberry Bliss Cupcakes mimic the flavors of the classic Starbucks treat. With a cranberry filling and cream cheese icing, they are the perfect bite.
Or turn them into my Tagalong Cupcakes if peanut butter and chocolate are more your thing. My Chocolate Peanut Butter Cupcakes are a fave low carb recipe in my house.
