Easy enough if you’ve never baked before. Impressive enough if you have.

Tools You’ll Need

Nothing fancy here:

• Standard 12-cup muffin tin
• Paper cupcake liners
• Mixing bowls (one medium, one large)
• Electric mixer (hand mixer or stand mixer, either works)
• Measuring cups and spoons
• Wire cooling rack
• Rubber spatula
• Ice cream scoop (makes filling the liners super easy)

The Ingredients

Okay, let’s talk about what goes into these babies.

The magic ingredient? Sour cream. It keeps everything moist and tender.

And the vanilla bean paste? That’s what gives you those gorgeous little specks and deep vanilla flavor.

Here’s your shopping list:

For the Cupcakes:

• All-Purpose Flour – This is your base, the structure
• Baking Soda and Baking Powder – These work together to make the cupcakes light and fluffy
• Salt – Brings out all the other flavors
• Butter – Unsalted, softened to room temperature (this is important!)
• Granulated Sugar – For sweetness and that tender crumb
• Eggs – Room temperature, please (I’ll explain why later)
• Full-Fat Sour Cream – The secret weapon for moisture
• Vegetable Oil or Canola Oil – Keeps everything soft
• Vanilla Extract and Vanilla Bean Paste – Double the vanilla, double the flavor

For the Vanilla Buttercream:

• Butter – Again, unsalted and softened
• Powdered Sugar – Makes it smooth and sweet
• Vanilla Bean Paste – Those beautiful specks!
• Whole Milk – Gets you that perfect creamy texture

Want to Mix Things Up?

The basic recipe is amazing. But sometimes you want to get creative.

Try these:

• Funfetti style – Fold rainbow sprinkles right into the batter
• Chocolate chip – Toss in some mini chocolate chips
• Almond twist – Swap half the vanilla extract for almond extract
• Lemon version – Add lemon zest to both batter and frosting
• Different frosting – Cream cheese frosting or chocolate buttercream work great too

How to Make These (Step by Step)

1. Get Your Pan Ready

First things first.

Preheat your oven to 350°F. Line your muffin tin with paper liners.

This saves you from scrubbing later. Trust me.

2. Mix the Dry Stuff

Grab a medium bowl. Whisk together your flour, baking soda, baking powder, and salt.

Set it aside.

3. Cream the Butter and Sugar

Here’s where the magic starts.

Beat your softened butter and sugar together for 2-3 minutes. You want it light and fluffy.

This creates tiny air pockets. That’s what makes your cupcakes tender.

4. Add Eggs and Vanilla

Beat in your eggs. One at a time. Mix well after each one.

Then add your vanilla extract and vanilla bean paste. Mix until it’s all combined.

5. Prep Your Wet Mix

In a small bowl, whisk together the sour cream and oil.

This is your moisture bomb.

6. Bring Everything Together

Now here’s the trick.

Add half of your flour mixture to the butter mixture. Mix on low speed.

Add the sour cream mixture.

Then add the rest of the flour.

And here’s the most important part…

Stop mixing as soon as it’s combined.

Seriously. Overmixing makes dense cupcakes. Nobody wants that.

7. Fill and Bake

Divide your batter evenly among the 12 liners. Each should be about two-thirds full.

Bake for 16-18 minutes.

How do you know they’re done? Stick a toothpick in the center. It should come out clean.

The tops should spring back when you touch them lightly.

8. Let Them Cool

This is the hardest part.

Waiting.

Let the cupcakes cool in the pan for 5 minutes. Then move them to a wire rack.

They need to cool completely before frosting. About 30 minutes.

I know it’s torture. But warm cupcakes = melted frosting disaster.

9. Make That Buttercream

Beat your softened butter for 2 minutes until it’s creamy.

Then slowly add your powdered sugar. One cup at a time. Beat it well.

Add the vanilla bean paste and 2 tablespoons of milk.

Now beat on high for 3-4 minutes. You want it light and fluffy.

Too thick? Add more milk, a little at a time.

10. Frost Away

Grab a piping bag with a star tip if you’re feeling fancy.

Or just spread it with a knife. Either way works.

Swirl that buttercream generously on each cupcake.

How to Serve These Bad Boys

These cupcakes are ready for anything:

• Birthday parties – Load them up with sprinkles, candles, fun decorations
• Baby showers – Use pastel sprinkles or cute fondant shapes
• Weddings – Go elegant with fondant flowers or gold leaf
• Just because – Sometimes you don’t need a reason for cupcakes
• With ice cream – Vanilla ice cream on the side? Yes please.

Want to make them extra special?

Add rainbow sprinkles. Edible glitter. Fresh berries. Chocolate shavings.

Go wild.

Keeping Them Fresh

Unfrosted cupcakes:

Room temperature in an airtight container: 2 days

Refrigerator: up to 5 days

Frosted cupcakes:

Refrigerator in an airtight container: up to 4 days

Just bring them to room temperature before serving. They taste way better.

Freezing:

Freeze unfrosted cupcakes for up to 3 months. Thaw them overnight in the fridge, then frost.

My Tips for Perfect Cupcakes Every Time

I’ve made these cupcakes more times than I can count. Here’s what I’ve learned:

• Room temperature ingredients matter. Cold butter, eggs, and sour cream don’t mix smoothly. Let them sit out for 30 minutes.
• Don’t overmix. I can’t stress this enough. Mix just until combined.
• Use an ice cream scoop. It makes filling the liners perfectly even. So satisfying.
• The toothpick test is your friend. Clean or with just a few moist crumbs = done.
• Patience with cooling. I know you’re excited. But wait.
• Thin buttercream? Add more powdered sugar. Too thick? Add milk one teaspoon at a time.

Your Questions Answered

Can I skip the vanilla bean paste and just use extract?

Yep. Use 2 teaspoons of vanilla extract total in the cupcakes and 1 teaspoon in the frosting.

Why did my cupcakes turn out dense?

Two reasons usually.

Either you overmixed the batter. Or your ingredients were too cold.

Mix just until combined. And make sure everything’s at room temperature.

Can I make these ahead?

Absolutely.

Bake them up to 2 days early. Keep them unfrosted at room temperature.

Frost a few hours before serving.

My buttercream isn’t smooth. What did I do wrong?

Your butter probably wasn’t soft enough. It should be softened, not melted.

And beat it for several minutes. That’s what makes it fluffy and smooth.

Can I use different frosting?

For sure.

Cream cheese frosting is amazing on these. So is chocolate buttercream. Or even whipped cream frosting.
