This dense, delicious Vanilla Cake with White Chocolate Buttercream topped with White Chocolate Curls made a dreamy, one layer birthday cake!

With a variety of picky palates in our household, I went to our favorite white chocolate cupcake recipe and baked it up in an 8-inch cake pan. There were absolutely no complaints or leftovers!

Vanilla Cake with White Chocolate Buttercream

Bill’s birthday was approaching, and even though I know he’d prefer the most decadent dark chocolate dessert I could create, he always selects a birthday cake that Katie would enjoy. This year, instead of the yellow cake with chocolate icing we’ve had the past 3 or so birthdays, he asked for a white chocolate cake.

I decided to convert our favorite white chocolate cupcakes recipe into an 8 inch cake and use the same exquisite Swiss buttercream for icing.  And voila…Vanilla Cake with White Chocolate Buttercream. The cake turned out denser than I expected, but still really tasty…though the true star of the show was the white chocolate icing and jumbo white chocolate curl garnish.

Converting a Cupcake Recipe into a Cake

I decided to convert our favorite white chocolate cupcakes recipe into an 8 inch cake and use the same exquisite Swiss buttercream for icing.  And voila…Vanilla Cake with White Chocolate Buttercream. The cake turned out denser than I expected, but still really tasty…though the true star of the show was the white chocolate icing and jumbo white chocolate curl garnish.

To convert a recipe for 12 cupcakes into a cake, this method works for most recipes. 

  • Make the cupcake batter as directed in the recipe.
  • Once it’s mixed, scrape it into a greased 8-inch cake pan.
  • If you’re worried about sticking, line the bottom of the pan with a round of parchment, then grease the top of the parchment.
  • Bake for about 25 minutes or until a toothpick inserted in the middle comes out clean.
  • Cool on a rack for about 15 minutes, then invert it onto a wire rack to finish cooling.
  • Frost as desired.

White Chocolate Curls

And in case you haven’t mastered the chocolate curl, read on. I’ve abandoned the vegetable peeler and started using the Pioneer Woman’s method, first shared in this blog post for my Fluffy Chocolate Dessert.

White Chocolate Curls

A beautiful topping for white chocolate or vanilla desserts!

  • Author: Liz Berg
  • Prep Time: 10 minutes
  • Total Time: 10 minutes
  • Yield: 3 ounces 1x
  • Category: Garnish
  • Method: Melting, Chilling
  • Cuisine: American

Ingredients

  • 3 ounces of white chocolate
  • 1 teaspoon of shortening

Instructions

  1. Melt chocolate with shortening (I use the microwave). Spread the warm chocolate out on the back of a sheet pan with an offset spatula….nearly covering the whole surface. The layer should be thin, but not translucent.
  2. Place it in the freezer for 2-3 minutes. My chocolate was a little too hard when I pulled it out, but it was curling consistency after a minute or so at room temperature.
  3. Using a metal bench scraper (but you could use a metal spatula with a very straight/sharped edged scooping end), scrape off chocolate curls. Not every piece was perfect, but the leftover shards could still be used for garnishing. These curls will get soft as they warm up to room temperature, so refrigerate till needed.

  30. Hi Liz,
    Just stopped by to say thanks for being a part of the YBR this month.:) I hope your husband and family are doing well. Hugs

  31. I came across your blog whilst trying to look for a similar recipe. My question is can you use meringue powder instead of egg whites for this recipe and what do you think about cream cheese as some other recipes on the web use that. Your feedback and advice is greatly appreciated. BDW beautiful cake!!!

    • I’ve only tried meringue powder in royal icing and I’m not sure it would give you the results you’re looking for. I think a cream cheese frosting with white chocolate would be a better bet. I have a recipe coming up on Thursday that uses that frosting flavor profile on a red velvet cake…it was delicious!

  32. Thank you so much for your help:)

  33. You always make me want to break my diet!

  34. It’s gorgeous:@)
