Ingredients

Ingredients

  • 4 oz (113 g) Pasturized liquid egg whites
  • 3 tsp (3 tsp) Créme bouquet optional flavoring
  • 1/4 tsp (1/4 tsp) Fine salt
  • 16 oz (454 g) Powdered sugar
  • 1 tsp (1 tsp) Vanilla extract
  • 1 dash (1 dash) Lemon extract
  • 6 oz (170 g) White chocolate Good quality
  • 24 oz (680 g) Butter room temperature

Instructions

Instructions

  • Melt white chocolate. Make sure it’s completely smooth! Set aside while you mix the other ingredients.
  • Start blending egg whites & powdered sugar slowly in stand mixing bowl with whisk attachment until powdered sugar is combined. 
  • Add crème bouquet, salt, vanilla, and dash lemon extract. Speed up to high until thick and glossy (about 4-5 minutes).
  • Add butter, a large piece at a time, while continually whisking on medium speed. Whisk until fully blended. Mixture may look a bit curdled. No worries! The next step fixes that.
  • Add melted white chocolate to mixture, careful not to touch sides of bowl. I like to make a well in the center of the bowl & pour the white chocolate into it. Start whisk on slow & quickly increase to medium-high. 
    Do not let the white chocolate touch the sides of the bowl, sit for any length of time, or not get mixed in immediately or it will cool into lumps throughout the icing. Scrape it down several times until fully mixed in.
  • Whisk on medium-high for a few minutes, until light & fluffy and white in color.

Notes

I love the Cremé bouquet, but if you don't want to use that no worries. Just use your vanilla. The dash of lemon extract really brings out the flavor & cuts the sweetness, but again, optional.
This is a great base for just about any flavor too. Start with this, then mix in strawberries, salted caramel, oreos, etc etc.
To make a chocolate version, just sub 1/4 cup cocoa for 1/4 cup of the powdered sugar, reduce egg whites to 75 g & change white chocolate to semi-sweet chocolate chips. It does tend to be softer though, no matter what. Tastes amazing though!

    1. In the microwave. 30 seconds to start, stir. Then 15 second intervals until melted. Let cool to 80ºF before pouring into the buttercream

  1. Do you have a suggestion on how to make this buttercream with matcha green tea flavor?

  2. would this be ideal for piping flowers to put on cakes? I would imagine the white chocolate would make this a bit firmer than your regular easy buttercream. I would prefer to use this as I find the easy buttercream to be perfect.

    1. You can pipe flowers with any buttercream, it’s all about just working with the right temp of buttercream. Working quickly and not warming it too much in your hand.

  3. If I use 1/2 lb of Spectrum to replace 1/2 lb of the Butter will that help Stablize it for a covered area outside? It’ll be about 82-85. It’ll only be a filling. I’m just not sure if I just want straight Ganache because it’ll have fresh fruit. Thank you

    1. Sorry, not sure what spectrum is? Shortening I assume. You can replace all the butter with shortening if you like, it will just have a much greasier mouth feel and not be quite as stable as ganache

  4. Hi Liz,
    I’m going to make this frosting with the white mud as a filling and cover. If I want to colour it, would I have to use oil based colours because of the chocolate? Also, when telling clients about this flavour, would I just say, white chocolate, or is more a buttery flavour.
    thanks

  5. I have seen lots of comments about freezing this BC. However, once you have decorated the cake with the white chocolate bc, can you freeze the cake. . Will bc cake crack upon thawing

  6. How long will the BC stay fresh? I am making a wedding cake, I need to transport the cake the day before it’s required.

  7. How long can it be keep in the refrigerator and then taken out to re whip it.

  8. Hi. Should I double this recipe to cover a 3 layer- 8 inch round cake?

  9. should I use a Wilton gel food coloring or a Wilton icing coloring?? is there a difference??

  10. Hi liz we don’t have this type of egg white in my country I only do regular imbc,smbc,fmbc how can I turn it into white chocolate bc please help?

  11. Can I put tiny TINY drop purple food coloring for a whiter frosting? same on your buttercream frosting. I really like white frosting but with white chocolate flavor.

    I love your easy buttercream recipe!! Everytime i make a buttercream recipe from someone else, i regret it and go back to yours.
    I have made this one with speculoos spread instead of the white chocolate. It was delicious.
    I always use egg white powder, which works great! I have never seen pasteurized eggwhites in the stores here (Netherlands)
    Thank you for all your delicious recipes. I will keep trying them out!

    I love this frosting! I don’t know why it took me so long to try it. I’m glad I did! The recipe was very easy to follow and the taste is amazing! Thank you

    Hi and thanks so much for this recipe. I’m going to try a chocolate drip cake with a white chocolate frosting and a dark chocolate ganache drip on top. Would this recipe work for covering the sides smoothly with sharp edges? Thanks in advance
