Sticky Ginger Cake with Caramelized White Chocolate Buttercream

This Sticky Ginger Cake with Caramelized White Chocolate Buttercream is so gingery, moist, sweet, and delicious!

Sticky Ginger Cake with Caramelized White Chocolate Buttercream

This ginger cake with caramelized white chocolate buttercream is loaded with so many gingerbread-y flavors, including molasses, brown sugar, cinnamon, powdered ginger, and even homemade stem ginger syrup.

What is stem ginger? I'd never heard of it before trying this recipe. Stem ginger is candied ginger in its own syrup.

You can make it by boiling fresh ginger in water for about an hour, and then adding sugar to some of the water and boiling it even longer. Once you've made it, you can keep it in the refrigerator and use it for lots of recipes calling for candied ginger. It will last about 6 months.

You can also substitute corn syrup or buy it on Amazon! (affiliate link)

Stem Ginger

How to make this sticky ginger cake:

First, you melt butter, molasses, corn syrup, stem ginger syrup, and vanilla in a saucepan. After that, stir in sugar off heat. 

Next, whisk together eggs and milk and stir them into the gingery mixture. Sift in the flour, baking soda, powdered ginger cinnamon, and a pinch of dried cloves. Finally, bake the batter in a parchment lined baking pan. The deliciousness of the cake will amaze you.

Once you have baked the cake, frost it with caramelized white chocolate buttercream frosting.

Caramelized White Chocolate Buttercream

How to make (or rescue) your caramelized white chocolate: 

This cake also includes a delicious buttercream frosting which includes caramelized white chocolate.

Caramelized white chocolate is made by baking white chocolate in an oven, stirring it every 10 minutes until it turns to a caramel color and is smooth and liquified. I know that it's possible because David Lebovitz, one of my favorite dessert icons, says it's possible, and he's proved it with photos.

Unfortunately, I was totally unsuccessful with the process for making caramelized white chocolate, with my chocolate ending up all grainy and powdery. I suspect it was because the white chocolate I used did not have high enough cocoa solids. I learned after making this cake that the white chocolate should have at least 30 to 35 percent cocoa solids. Unfortunately, most white chocolate does not come labeled with their cocoa solid percentages.

To save my Caramelized White Chocolate Buttercream, I processed the grainy mixture of caramelized white chocolate in a food processor. Next, I heated the grainy mixture in the microwave for about a minute. After that, I brought about 1/3 cup of heavy cream to a boil and dropped the white chocolate mixture into the hot cream.

Finally, I used an immersion blender to mix the cream and white chocolate and get rid of the graininess. I added this mixture to the buttercream, and, guess what? It worked! In fact, my taste testers reported that the "frosting is amazing!"

P.S. For a quick and easy white chocolate dessert, be sure to try White Chocolate Muffins

This cake was amazing. After all of my issues with the frosting, it was totally worth the trouble. If the frosting frustrates you, just substitute some melted caramel and add it to the frosting.

One thing I did need was an 8 x 12 inch rectangular cake pan. I can't believe I had to buy a new pan!

  1. Hah, I didn't go with this selection just because of that stem sugar syrup. Thanks for the tip on making my own.

    1. The cake seemed easy at first glance until I had to figure that one out!

  2. That's amazing. Sorry you had to go to so much trouble with the frosting. Unfortunately if your family loves it, they may make you make it that way again!! Looks great.

    1. Ha ha! I'm going to have to find the good stuff!

  3. Yes, white chocolate is so so tricky, you need the real best stuff to do the caramelized trick - but you turned a disaster into total bliss, so MORE POWER TO YOU!

    I have her cookbook, so I will be following your adventures as you guys bake from it - she was great on the show

    1. Thank you! I was so frustrated but determined to make the best of it. Plus, I didn't want to throw out all of that chocolate. I wish her cookbook would have said that upfront rather than a postscript! And I'm very proud of my SAVE!

  4. You made so many amazing gingery components for this cake! It sounds packed with flavor!

  5. Great save with the buttercream! Stem syrup is new to me but I am a ginger fan. I'll save this one for our end of the year free-for-all!

    1. I've heard that if you use the good white chocolate there is no problem.

  6. So many great hints! I just got a bunch of ginger in our produce box and will definitely be making this.
