Chocolate Stout Cupcakes with Caramelized White Chocolate Ganache

This month’s Improv Challenge theme is Hearts and Flours…perfect for Valentine’s Day! Kristen of Frugal Antics of a Harried Homemaker is our lovely hostess….and our assignment was to make anything made with flour that incorporated hearts.  If you’d like to join our group, feel free to contact Kristen…March’s pairing is peas and carrots…I don’t think a dessert is possible with that combo! Darn.

Not being too creative when it came to this theme, I grabbed the jar of Valentine sprinkles and remembered the stout cupcakes with caramel buttercream that my friend, Jan, raved about. Chocolate pleases the hubby…and caramel reels me in every time. But I took it in my own direction when I remembered reading about David Lebovitz’s Caramelized White Chocolate. White chocolate discs are baked in a low-temperature oven, stirring every 10 minutes, till caramelized. I added this chalky, tan concoction to hot cream with a pat of butter and whisked till it resembled caramel sauce. I let it cool and beat it into an amazing whipped ganache.

Almost unprecedented, these cupcakes drew praise from the hubby, the daughter and me! I did take liberty with the beaters and mixing bowl, licking any and all remains! I wouldn’t say the frosting tastes like white chocolate nor caramel, but something in between…unique and just exquisite. These Chocolate Stout Cupcakes with Caramelized White Chocolate Ganache were divine!

If I’ve inspired you to try this icing, make sure to check out Lebovitz’s post linked above. I found I had a few teeny chalky bits in my “caramel” which were probably due to 10 minutes too long in my oven. Pressing the mixture through a fine-mesh sieve would have alleviated any lumps…and there’s a lot more troubleshooting and details in his post.  Doesn’t the resulting mixture look like caramel? I chilled it, then whipped it to a frosting consistency. I will play around with the amount of cream next time…I started with a half cup, but think I’ll add an extra tablespoon of cream. If you like to experiment in the kitchen, this is one cupcake you need to try.
