For the past several years, I’ve always shared some sort of cake or decadent sprinkle-coated dessert this last week in June, because it’s a pretty big week around here. 

2019: Funfetti Babka
2018: Almond Rhubarb Cake
2017: Funfetti Bundt Cake
2016: Peanut Butter Banana Cupcakes
2015: Chocolate Oreo Peanut Butter Torte
2014: Chocolate Peanut Butter Cup Cake

Why the celebratory dessert trend?  The last week in June includes not only my birthday, but also my blog-iversary.  I hit publish on the very first post on Bunsen Burner Bakery on June 28th, 2011 (a dark chocolate cheesecake recipe, for those who are curious).

So this year, I’m sharing another celebration-worthy dessert: this amazing rainbow layer cake recipe, which served as a very special 2nd birthday cake for our favorite little girl back in April.  

It’s so fittingly appropriate for so many reasons.  A tall, beautiful rainbow cake?  I’d love one for my birthday!  Or my blog-iversary.  June is Pride Month – now we can even celebrate with a giant edible rainbow.  And of course, the state of the world is more than a little dreary, so how about a rainbow cake to brighten things up?

So come along for all the tips you need to make a beautiful rainbow cake of your own.  It’s easier than you think, especially because this one is neither six cake layers tall (i.e., so tall your cake is at risk of sliding off without wooden dowels to anchor it), nor does it involve cutting cake layers in half, which is not the easiest.

Easy recipe, beautiful cake.  Just the way it should be.
