A holiday classic, this peppermint white chocolate bar recipe is a must-try. Your whole family will love the chewy dessert bar and fluffy peppermint frosting!

The combination of chocolate and peppermint is everywhere during the holiday season and I am not complaining one bit! I love these bars because they call for both white chocolate and milk chocolate chips. The combo isn’t overly sweet, which makes for a great bite alongside each bite of peppermint frosting.

What is a peppermint white chocolate bar?

Dessert bars are neither a brownie or a cookie – but they are all delicious! I love a bar, and I have plenty of favorites here (check the end of this post for a few I want to share). These are found all over the world, with thousands of variations, but the idea is thought to have come out of the U.S. and gained popularity through Betty Crocker’s dessert bar mixes. 

I always prefer home made and this peppermint white chocolate bar is great for everything from holiday parties to on-the-go snacking since they are hand-held and won’t fall apart! This version is great for gifting and can be stored in the freezer for many months. 

Ingredients //

We have ingredients for both the bar and the frosting, and I have separated them that way 

This is two photos showing the ingredients for the cookie bar on the left, and the peppermint frosting on the right.

For the bar (photo on the left) you will need basics like eggs, flour, butter, sugar, and vanilla extract.

You will also need chopped white chocolate; I recommend finding a brand that does not use palm oil, as it can create a greasy texture. Finally, mini chocolate chips and peppermint extract  round out this portion. 

The peppermint frosting (photo on the right) is made with more white chocolate as well as vanilla and peppermint extract. It also calls for butter, powdered sugar, sour cream, salt, and some peppermint candies we will crush. 

How to // The Steps 

  • Begin by melting the white chocolate and butter over a double boiler.
  • Once melted, take off the heat and whisk in sugar, eggs, vanilla, and peppermint extract until smooth.
  • Add the flour and mix completely.
This is a collage of the initial steps of this recipe, ending with a prepared batter.

  • Prep a 9×13 inch pan with non-stick spray or butter. 
  • Pour batter into your pan and bake for 28 to 30 minutes.
  • Once they’re out of the oven, sprinkle on chocolate chips and let them cool. 
This is a process shot of the bars before baking, after baking, and after the addition of chocolate chips.
  • While those cool, melt the next portion of white chocolate for your frosting. Set it aside. 
  • Next, cream together butter powdered sugar. 
  • Beat in sour cream, vanilla, peppermint extract and salt on low until combined. After that, pour in the white chocolate and beat until smooth. 
  • Then, add the remaining powdered sugar and mix until combined.

What makes this peppermint white chocolate bar so good? // 

I love these because of their flavor combo, and the incredible smell they make in the oven – but also: 

  • These freeze really well, making them great to make ahead 
  • The peppermint flavor can be toned down easily to adjust for taste buds
  • You don’t have to choose between a cookie or a brownie! With this bar, you can have both

Serving Suggestions // 

I like to slice these small to start, since they are so rich! Of course a glass of milk or a cup of coffee goes really well with these. 

Storing and Gifting your Peppermint White Chocolate Bars // 

The peppermint flavor is usually associated with the holidays, but these are great year-round and they’re easy to pull from the fridge when you get a hankering in March! 

To eat within the week: Cut the pan into squares. Line the base of an air-tight container with parchment paper and start adding the bars. You will want to keep parchment between each layer; they will hold up in the fridge for about five days before starting to dry. 

To enjoy these later, start out by putting the sliced peppermint white chocolate bars on a cookie sheet. Line them with 1-2 inches between each piece and freeze for an hour. After that, line an air-tight container with parchment paper and stack the bars with more parchment between each. 

If gifting these, it’s important to note that the frosting is best when it has been chilled. Wrapping them in parchment paper and then plastic wrap, will keep them cooler and fresher for longer! Throw a little bow on, and these are a hit!

    Those look refreshing yet decadent all at the same time and your photos of these bars are perfect, clean and gorgeous as if you have been trained in food photography. This dessert speaks to me loud and clear as I think mint and chocolate is a mix made in heaven. Whenever I get ice cream, it’s hard for me NOT to get mint chocolate chip!

  10. Julia {The Roasted Root}

    Wow, these bars look awesome and I’ve never had a Christmas treat like this! I could easily see this recipe become a family holiday tradition. Think you could do 52 weeks of Christmas cookies? 😉 Happy holidays, lady!

  13. Spencer

    1. bakedbree

      thanks Jennifer! I love these bars, they are so pretty too!

  15. Mary orourke

    Can you please clarify the amount of powdered sugar in the frosting? I see that originally you mix butter with 1 3/4 cup. I cannot see that i add any more. The recipe calls for 3 1/2cups. Am i missing something?
    Thanks.

    1. bakedbree

      It is 3 1/2 cups. You add it in two additions as to not get sugar all over your kitchen.

  16. Kitty

    These do look excellent, ta! One question. How long should the 12 oz of white chocolate and butter cool before whisking in the sugar, eggs, vanilla, and peppermint extract? Or do you temper so the eggs won’t ‘curdle’/start cooking?

    1. bakedbree

      Cool enough to not scramble the eggs, I do not temper it.

  17. Jennifer

    Confused about how much powdered sugar goes into the frosting…3-1/2 or 1-3/4cups?

    1. Jennifer

      Now I see the comments…thanks!

  18. Colleen

    Thank you for the lovely recipe! I made these for an office holiday potluck today and they were a hit! Many colleagues telling each other, “You’ve got to try one of those!”

    1. bakedbree

      Just what I like to hear!

  19. Lizzy

    I just made these and they are cooling but smell absolutely delicious! The print of recipe doesn’t say to add the rest of the powdered sugar though, just a heads up(: I can’t wait to try them!(:

    1. bakedbree

      thanks Lizzy! I’ll fix it.

  20. Yesenia

    These look amazing!

  21. Jill

    I want to try these for sure! Question though, with the sour cream in the frosting, is it safe to leave out?

    1. bakedbree

      I don’t ever really leave anything out. I’d keep them in the fridge.

  22. Sallie Zimmerman

    Can you freeze these bars?

    1. bakedbree

      Yes you can.
