Out of all of the many desserts I make, these simple vanilla cupcakes are the most requested treat among my circle of friends. They are incredibly fluffy, full of real vanilla extract, and stay moist for days. When I developed this recipe years ago, I wanted to make a go-to vanilla cupcake that was super easy to make—they stir together and are baked in less than 30 minutes.
One common issue with cupcakes is that they dry out fast. My recipe stays moist for a few days. So what’s the secret? Sour cream! Get all of the tips I gathered from testing this recipe to help you bake cupcakes that are perfectly fluffy, moist, and full of flavor.

Key Ingredients

These are the main ingredients you need to make homemade vanilla cupcakes. You can find the full list of ingredients and measurements in the recipe card below.
All-purpose flour – this kitchen staple is perfect for super fluffy, moist vanilla cupcakes! No need for specialty flours like cake flour in my recipe.
Granulated sugar – while it’s most commonly thought that sugar just lends sweetness to recipes, in cakes, it is also essential for moist crumbs and a light texture. Stick to granulated or white sugar for this cake batter recipe, and don’t decrease the amount, or the cupcakes will be dense and dry.
Milk – whole milk is ideal for its fat content. 2% can be used in a pinch. Bring it to room temperature before starting the batter; cold milk will solidify the melted butter.
Sour cream – this tangy, thick cultured cream helps in two main ways. It provides acid for the baking soda and baking powder to react and help the batter rise in the oven. It’s also the secret to incredibly moist cupcakes and will keep them that way for days. (More on the science behind it, below!)
Eggs – you only need the egg whites for the cake batter. Separate the eggs while they are cold, then let the white come to room temperature. When you separate the eggs, reserve the yolks for a custard, lemon curd, or use them to make a batch of French Buttercream!
Butter – unsalted butter gives the cupcakes a rich flavor, and melting it first means you don’t have to beat it into the batter, making this a super easy vanilla cupcake recipe.
Vanilla extract – pure vanilla extract is the best choice. You can use vanilla bean paste for a classy, bakery look if desired!
A bit of advice on the ingredients: You can get the cheapest flour, sour cream, milk, and even butter, but you have to get good vanilla for this recipe! It’s the main flavor, and you want it to shine, so go find a good, real vanilla extract. If you want to get points for being fancy, use some vanilla bean paste while you’re at it. People love seeing the little specks of vanilla in the cupcakes and frosting!

The Secret To Moist Cupcakes: Sour Cream
I love using sour cream in my cake recipes to make them moist and tender! So what’s the science behind this? Well, the lactic acid in the sour cream weakens the proteins in flour that form gluten, so the cake turns out more tender. Because sour cream also contains fat, it helps keep the cakes from drying out as quickly.
It’s the secret to my perfect Devil’s food cake and strawberry cupcakes, too! If you don’t have sour cream, you can use a thick Greek yogurt instead. Just be sure to use one with fat—2% minimum, with 5% being ideal.

Which Type Of Frosting Is Best For Vanilla Cupcakes?
There are so many options to choose from! My vanilla cupcakes are a delicious foundation for all different flavors and styles of frosting. Here are three of my favorite types for you to choose from, depending on the type of frosting you like or how sweet you want it.
American Buttercream: Sweet And Easy
Beat room temperature butter with powdered sugar, a pinch of salt, and some vanilla extract until light and fluffy. Super fast and a total crowd-pleaser! Check out my vanilla buttercream post for all the tips and tricks as well as a full how to video!. You can also make flavored versions with strawberry buttercream, Oreo frosting, and chocolate buttercream.
Swiss And Italian Meringue Buttercream: Silky, Light, and Not Too Sweet
Swiss and Italian buttercream are both meringue-based, so you’ll be adding butter to a fluffy meringue made with egg whites and sugar. The result is light as air, smooth as silk, and totally delicious. Not very sweet, but really, they let the cake shine through. Try my Swiss meringue buttercream and Italian meringue buttercream recipes and check out my tips and tricks for the perfect frosting!
French Buttercream: Pipe-Able Custard
French buttercream is made with egg yolks, sugar, and butter, so it naturally has a beautiful pale yellow color. It tastes like a custard and has enough structure to pipe easily. Very underrated, and you can use the extra egg yolks from this recipe to make it! Try my French buttercream recipe on your next batch of cupcakes.

Pro Tips For The Best Vanilla Cupcakes
Measure your flour correctly! Adding too much flour to the recipe is the most common mistake. The best and easiest way to measure flour is by using a scale. If you don’t have one, then fluff your flour with a spoon, sprinkle it into your measuring cup, and use a knife to level it off.
Cupcake liners come in different sizes. Be sure to use regular cupcake or muffin pans with regular paper liners. You can choose festive ones, or put them inside decorative sleeves after baking, as I did! I found these pink polka dot ones online.
Make this into funfetti cupcakes! You can definitely add sprinkles to the cake batter. About ⅓ cup should do, to make this an amazing funfetti cupcake!
Everyone’s oven is slightly different. I like to turn my pan halfway through baking to promote a more even bake, in case there’s a hot spot.
Towards the end of the baking time, I keep a close eye on the oven. Once the centers are springy and a toothpick comes out clean, the cupcakes are ready. Being watchful at the end lessens the chances of having caramelized dark edges on your cupcake, ensuring it’s light, soft, and moist!
How To Make Vanilla Cupcakes
Below, I’ve highlighted portions of the recipe in step-by-step process images along with instructions for making these easy vanilla cupcakes. You can find the full set of instructions in the recipe card below.

1. Preheat the oven to 350°F. Arrange 16 cupcake liners between two cupcake pans. In a large bowl, add the flour, sugar, baking powder, baking soda, and salt. Whisk to combine.
2. Add the sour cream, milk, vanilla, melted butter, and egg whites in a separate bowl. Whisk the wet ingredients together until well combined. The mixture will probably not be completely smooth as the butter might clump up a bit but it will be fine so don’t fret!

3. Add the wet mixture to the dry mixture and fold just until combined. Don’t overbeat it, though; a few small lumps are okay.
4. Scoop the vanilla cake batter into the cupcake papers and fill each one about ⅔ full. Bake at 350°F for about 18 minutes or until the centers JUST spring to the touch.

5. Allow cupcakes to cool for a few minutes in the pan, then remove and place on a cooling rack to cool completely. Use a stand mixer with a paddle attachment to beat together the frosting ingredients until smooth and fluffy.
6. Pipe the vanilla buttercream frosting on top of each cooled cupcake. I’m using an 849 tip, but any star tip will do nicely.

Frequently Asked Questions
These cupcakes are fine overnight if left covered. You can refrigerate them for three days, but they should come to room temperature before eating. The butter-based cake needs to warm up a bit. If unfrosted, you can wrap and freeze the cupcakes for up to two months.
YES! I skip the yolks for a whiter cake, but you can use the whole egg; just reduce the sour cream by ¼ cup.
I LOVE the taste of butter, which is why I’ve used it in this recipe, but if you’re making cupcakes in advance and will be chilling them, then you may want to sub in some vegetable oil or replace the butter altogether. An oil-based cake will stay softer when cold. To make a complete substitute, use ¾ cup vegetable oil minus 1 tablespoon, as the oil has a higher fat content than butter.

Absolutely delicious!
COLEEN MCCUNE says
These cupcakes are simply amazing! I always double the cupcake recipe but halve the frosting recipe. This gives me just enough frosting for a generous swirl design on each cupcake. I use Nielsen Massey vanilla for the cupcakes and Trader Joe’s butter, which is an excellent quality and price point as well as being a nice pale yellow color. Because I do not like to use food coloring in the frosting, I use Trader Joe’s vanilla bean paste. It keeps the frosting a nice white color and the vanilla bean flecks looks so tasty. Thank you so much for this wonderful recipe!
