So what to serve for a RootBeer Birthday – Rootbeer Cake, of course! I didn’t even know there was such until I stumbled upon it over at Joy the Baker. With ice cream, it can be called the “Rootbeer Float Cake” – and it needs ice cream – it’s really rich (and yummy!). There’s almost a can of rootbeer in the cake batter and another 1/2 a can in the icing, if I remember right. I couldn’t taste it too much in the cake, but it was noticeable in the icing. Head over to the link above for recipe and directions.
