Tanners Luigi cake

Here is sweet Tanners Birthday cake. It’s a root beer cake with root beer filling and his favorite game person on top, Luigi. An easy way to make root beer cake is to substitute some of the liquid for a cake mix or a, from scratch cake with the root beer flavoring. You can measure out how much you use and taste the batter until you get the taste you want then add the rest of the liquid. If you add a vanilla flavored icing or layer it with vanilla cake you have vanilla root beer cake. How easy is that?
