Before my daughter's 5th birthday, I was curious to try a new recipe for a birthday cake. We always lean towards the traditional chocolate cake, that's fantastic, of course, but as my daughter is unusually excited about rainbow and unicorns, I decided I must try to re-invent the concept of birthday cakes, or at least add an option to the menu :) So here it is! A sprinkle vanilla cake that's festive and truly comes together beautifully. It holds together really well, and can be decorated with frosting that's plain vanilla or with a touch of more sprinkle. Although the cake was well received by all tasters, my daughter still went for the chocolate cake for her party (alas!). Do your kids prefer chocolate or vanilla?
