These soft and moist White Chocolate Cupcakes are the perfect vehicle for my creamy peanut butter frosting. They’re a match made in heaven! I’ve twisted the frosting with vanilla to create a swirl on top!

These cookies were originally published in February 2013. I updated the recipe notes and images in August 2025.
Aimee’s Recipe Notes

Taste & Texture- Soft, moist cupcakes with a hint of white chocolate. Topped with a swirls of creamy peanut butter frosting and vanilla frosting.
Serving Note- These cupcakes don’t “dome” like typical cupcakes. The white chocolate is a little heavier, but they do get a crunchy topping like brownies.
Storage- Keep cupcakes in an airtight container for up to one week.
Top Tip- These cupcakes were inspried by white chocolate Reese’s cups. Add one to the top of each cupcake for a sweet garnish.
Cupcake & Frosting Ingredient Notes

Scroll down to the recipe card below for the full list of ingredients with measurements. Here are a few highlights.
- Egg Whites – Separate them from the yolks a few minutes ahead of time so they can come to room temperature before you make the cupcakes. Use the yolks to make my drop sugar cookies or lemon curd!
- Cake flour – This flour is processed to remove more of the gluten than all-purpose, creating a light and airy cupcake.
- White Chocolate Bar – Use a good quality white chocolate for best taste. I used Green & Black’s. You’ll need some for the cupcake batter and more for the frosting.
- Peanut Butter – Regular, shelf stable creamy peanut butter (like Jif or Skippy) work best.
How to Make White Chocolate Cupcakes

Make the cupcake batter.
- Whisk the egg whites and milk together. In a separate mixing bowl, beat the butter and sugar together, then add in the dry ingredients and the egg white mixture. After the other ingredients are combined, fold in a melted white chocolate bar and a little more milk.
- Divide the batter into a lined cupcake tin and bake for about 15 minutes. Let the baked cupcakes cool while you make the frostings.

Make the Frosting and Swirl.
- Make both frostings in separate bowls. Spoon into individual piping bags. Put both smaller pastry bags inside of an extra large pastry bag.
- Swirl the frostings onto the cupcakes however tall you like. I like a LOT of frosting on mine so I pipe it on extra high.

Tips & Tricks
- Use a 6S tip to make the frosting look like the cupcakes in these pictures.
- The peanut butter frosting is light so you may not see the swirl. That’s okay–you’ll taste it in each bite!
- To get the perfect sized cupcake, fill the liners only half full. This ensures even baking and a flat top perfect for holding all of that extra delicious frosting.
- Garnish with a mini white chocolate peanut butter cup for a pretty (and tasty) finishing touch!

White Chocolate Cupcakes Recipe
Ingredients
For the Cupcakes:
- 5 egg whites room temperature
- ¾ cup whole milk divided
- ¾ cup unsalted butter softened
- 1 ¾ cup granulated sugar
- 3.5 ounce white chocolate bar melted (I used Green & Blacks)
- 2 ½ cups cake flour
- 1 Tablespoon baking powder
- ½ teaspoon kosher salt
For the White Chocolate Frosting:
- 1 cup unsalted butter softened
- 2 cups powdered sugar
- 3.5 ounce white chocolate bar melted
- 1 ½ Tablespoons whole milk
For the Peanut butter Frosting:
- 1 cup unsalted butter softened
- 2 cups powdered sugar
- ⅓ cup creamy peanut butter
- 1 ½ Tablespoons whole milk
Instructions
- Preheat oven to 350 degrees. Line a cupcake tin with paper liners and set aside.
- For the cupcakes, whisk together the egg whites, and 1/4 cup of the milk in small bowl until slightly combined. Set aside.
- In mixing bowl, beat butter and sugar for 2 minutes on medium. Add in dry ingredients and mix until combined. Slowly in a steady stream add in the egg white mixture. Beat in remaining milk and melted white chocolate bar.
- Fill cupcake liners half full with batter and bake in a 350 degree oven for about 15 minutes. Remove and cool in pan 5 minutes then transfer to a wire rack. Cool completely before frosting.
- For the vanilla frosting, beat butter 5 minutes until it becomes pale in color. Add sugar, melted white chocolate and whole milk. Beat an additional 5 minutes until fluffy. Fill a disposable pastry bag with frosting (no tip on the end). Set aside.
- For Peanut Butter frosting, beat butter 5 minutes until pale in color. Add sugar, peanut butter and whole milk. Beat an additional 3-5 minutes until fluffy. Fill a disposable pastry bag with frosting (no tip on end).
- Take a LARGE pastry bag and add both types of frosting, making sure the ends of each bag go down to the bottom. Using a 6S tip, pipe onto cupcakes. The peanut butter frosting is very light, so it’s hard to see the swirl. That’s okay, you will taste it!!

Easy Cupcake Recipes
It’s the scrumptious marriage of white chocolate and peanut butter makes these cupcakes so wonderful! White Chocolate Cupcakes with Peanut Butter Frosting are a must try dessert for peanut butter lovers.









Yum! I LOVE peanut butter AND white chocolate so these sound amazing to me. I’ve never swirled frosting together when piping but you’re inspired me to try! 🙂
Oh Audra, it’s so easy!! You can do a chocolate vanilla swirl, which is impressive looking! Strawberry Chocolate Swirl. So many possibilities!!
These sound pretty close to perfect. PB and white chocolate are basically the only two things my boyfriend and I can agree on regularly 🙂
It’s good to find common ground. it’s better to find it in cupcakes 🙂
Oh no, now I will have to copy the vanilla bean cupcake recipe too!!! YUM!!! I can’t wait to get baking!!!! 🙂 Thank you so much ~ keep the great recipes coming!
Thank YOU Kathy. Here’s the recipe link for the Vanilla bean Cupcakes: https://www.shugarysweets.com/vanilla-bean-cupcakes-and-a-baby-shower
The very best white cake recipe I’ve ever made. It’s the base I use for all my variations (almond, lemon, confetti, etc). ENJOY!
Hi Aimee! First, I LOVE your site ~ all the recipes are to die for! I am getting ready to make your White Chocolate Cupcakes with P.B. Frosting – my hubby LOVES P.B. – but the instructions state “to whisk egg whites, vanilla paste, etc.,” I have almond paste, but vanilla paste? These look fab and I can’t wait to make them! 🙂
Kathy, I just fixed it. The vanilla paste was for the Vanilla bean cupcake version, and it referred to vanilla bean paste. These cupcakes don’t call for it!! ENJOY!!
These cupcakes are killing me!! White chocolate is my most favorite thing in the world! Mix that together with my other favorite thing…peanut butter and I am in heaven! Seriously! I need to make these immediately…or not, because that would be a bad thing for me to consume so many cupcakes and I know I wouldn’t be able to stop! I pinned this!
No you definitely need to make them immediately. And share 🙂
My husband says these are his favorite cupcakes I ever made. = that is saying something b/c you make more than anyone I know!
Aimee, I am a huge huge huge PB fan (wrote a book on it) and white chocolate! And this is a match made in heaven! Pinning!!!
What tip do you use to decorate and do you have any secrets for not wasting frosting and creating a huge mess..when I use a pastry bag, I swear, I make more of a mess than anything else! lol
Haha, I do make a lot of cupcakes! I used a large 6S tip. Make sure you use a 16inch bag, it will hold much more! Also, I take a chip clip (the kind that snaps close) and twist the end of my bag and clip it so that none leaks out the back end. I tend to use reusable pastry bags for frosting, I think they hold up better and are more flexible. I use the disposables when making royal icing for cookies. Hope that helps!!!
So helpful and thank you! I need to invest in some resealables I guess…the last thing I want to do though is clean them out…Lol
Cleaning them isn’t too bad. Just don’t let them sit and dry out with icing in them. Run hot water through them right away, Then a little dish soap and air them out (inside out) to dry.
These cupcakes are incredible! I love peanut butter, so these amazing looking cupcakes are right up my alley!
YES! All peanut butter lovers and non PB lovers can unite in this recipe!
I am one of those people who eat peanut butter out of the jar so these cupcakes are right up my ally. They look incredibly good! Pinning now.

I am not a huge PB fan either but these cupcakes woah! I love white chocolate so this might just convince me to try peanut butter frosting again.
I think you should definitely try it!
These look perfect and I love the white chocolate addition, especially with the peanut butter!
