My husband says these are his favorite cupcakes I ever made.

I’ve said it before, I like peanut butter, I don’t love peanut butter. My kids and husband LOVE peanut butter. So when I made these cupcakes I thought “perfect, something I won’t be tempted to eat.”

I was wrong. Let’s start with the cupcake base. I made this base using my favorite white cake recipe, and I added in some melted white chocolate. GOOD white chocolate. Not morsels. I used Green & Black’s White Chocolate bar for this recipe. It’s my favorite white chocolate…once you try it you will understand. It melts so smooth and creamy, not lumpy like most other white chocolates. PLUS, it has vanilla in it, which makes it the perfect bar to put in this recipe! The white chocolate does weigh the cupcake down, SLIGHTLY, so you won’t get domed tops. But don’t let the weight fool you. These are still light, airy cupcakes that are perfectly moist!

Now. The frosting. Remember I said I’m not a huge peanut butter freak. Apparantly that didn’t apply to this frosting. This frosting is made with MORE melted white chocolate and some creamy peanut butter. You really can’t tell from these photos, but I made TWO batches of frosting. One white chocolate and one peanut butter. I then swirled them together on top of the cupcakes. Because I didn’t go overboard on the peanut butter, the color is hard to differentiate. I then of course had to top each one with a White Chocolate Reese’s Cup (halved). This frosting is insane. Creamy. Light. Insane.

Of course I pipe my frosting high on cupcakes, so if you like to just spread a little bit on top, you probably won’t need the entire recipe. The cupcakes make about 24-30 cupcakes, so be prepared to feast! Or make sure you have company over to help you eat them! I am not responsible for YOUR lack of willpower. I have my own lack of willpower to deal with!

White Chocolate Cupcakes with Peanut Butter Frosting

White Chocolate Reese's Cups are the inspiration for these Cupcakes. White chocolate cupcakes topped with a creamy Peanut Butter Frosting!

Ingredients

For the Cupcakes:

  • 5 egg whites, room temperature
  • 3/4 cup whole milk, divided
  • 3/4 cup unsalted butter, softened
  • 1 3/4 cup granulated sugar
  • 3.5oz white chocolate bar, melted (I used Green & Blacks)
  • 2 1/2 cup cake flour
  • 1 Tbsp baking powder
  • 1/2 tsp kosher salt

For the White Chocolate Frosting:

  • 1 cup unsalted butter, softened
  • 2 cup powdered sugar
  • 3.5oz white chocolate bar, melted
  • 1 1/2 Tbsp whole milk

For the Peanut butter Frosting:

  • 1 cup unsalted butter, softened
  • 2 cup powdered sugar
  • 1/3 cup creamy peanut butter
  • 1 1/2 Tbsp whole milk

Instructions

  1. For the cake, whisk together the egg whites, and 1/4 cup of the milk in small bowl until slightly combined. Set aside.
  2. 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.
  3. 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.
  4. For the 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.
  5. For PB frosing, 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).
  6. 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!!

  1. Hi Aimee. This recipe looks wonderful! I was wondering if it would be possible to substitute the unsalted butter for salted and the whole milk for low-fat 1% milk? I just don’t buy unsalted butter or whole milk regularly.

  2. I made these tonight but was very disapointed as to how they turned out. They rose and then fell. The top of the cupcakes were crunchy and tasted like they had too much sugar in them. I have never had cupcakes fail like these did. The frosting also was very rich and almost unedible to the point where it makes you sick. A lot of money wasted on a not so good recipe.

    1. The top does get a crunchy coating (which I actually love!!), but they shouldn’t fall. Sorry you didn’t enjoy the recipe.

    1. You can, but it will change the texture! There are instructions out there on how to make all-purpose flour into cake flour (removing some flour and adding cornstarch, and sifting it). Just google it 🙂
