Vanilla Bean Cake with Dark Chocolate Frosting

Just recently we hosted survived my daughter’s birthday party ☺. Since the Christmas holidays we have celebrated my son’s 9th birthday and now my daughter’s 7th birthday. Winter babies make for a very busy start to each new year…but also lots of opportunities to challenge my vegan baking skills!  Similar to my son’s party a few weekends ago, my daughter was allowed to invite a few of her closest friends over for a sleepover party. In all she had three friends spend the evening. Between some Just Dance, playing some classic games like Jenga and dominoes, watching Gnomeo & Juliet and colouring the girls were occupied and quite content (the resident cats not so much). In the spirit of it being birthday season in our household (Janik’s birthday is in March, mine follows in April) today I’m sharing our recipe for Vanilla Bean Cake with Dark Chocolate Frosting.

I learned from my son’s birthday party that kids don’t care to eat that much at parties….or really at all 😛. We had a ‘create your own pizza’ theme for his party and while there was evidence of a few nibbles here and there for the most part our effort to make homemade (organic) pizza dough and provide a smorgasbord of toppings was for not. After all, boys just wanna have fun too right? Lol Instead of pizza I decided to serve up Macaroni & Cheese Bites (think Mac & Cheese meets muffins) for the all girls birthday party. Instead of serving our Creamy Dreamy Mac & Cheese on a plate (boring) I spooned the mixture into lined muffin trays, topped with vegan parmesan cheese, and  baked them for a few minutes. Voila….Mac Muffs! (as we affectionately called them). One of my daughter’s friends asked why the Mac & Cheese didn’t taste like the one she has at home so I politely answered ‘I just use a different kind of cheese, a rare cheese, in my recipe!”☺.  All things considered I would say this vegan birthday dinner was a success!

After much ado about her preference for a chocolate vs vanilla cake (and icing too) my daughter settled on vanilla cake with chocolate icing. I was determined to make a cake she would fall in LOVE with and worked hard to create a moist, sweet-but-not-too-sweet cake topped with a heavenly chocolate frosting. “Let it be fluffy” I muttered under my breath as I watched it bake. My cakes typically tend to end up – vegan or not – on the dense side. I wanted a lighter cake…the kind you can enjoy with a scoop of ice cream and fruit and not feel you’ve overdone it.   I’m happy to share that this vanilla cake is THE one! It is incredibly simple to make and requires most basic pantry ingredients save for the vanilla bean pod. If you don’t normally have vanilla bean pods on hand I encourage you to give it a try… the results are well worth it. They add an authentic vanilla flavour you just can’t get with extract 😉. A cake is only as good as the frosting on top and this Dark Chocolate Frosting hits the mark without a doubt! The combination of cacao nibs and cocoa powder gives it a rich flavour while the texture is creamy with that just-right amount of sweetness. The girls devoured the cake and most even had seconds! No one questioned whether the cake had eggs or milk….it was simply cake in their minds (bliss for a vegan parent!)

I hope you enjoy this recipe as much as my daughter and her friends did!
