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
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!
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!!
