Party Panache, Root Beer Float Cake

How about a good old fashioned Root Beer Float?

Cake style!

rootbeer soda cake

I got the idea for this cake when HH bought some beer called Best Damn Root Beer


It really does taste just like root beer!  But HH decided he prefers his beer to taste like beer 🍺

“Let’s keep it, it would be good for a marinade or something,” I said…..”hmmmm,

I wonder what it would taste like in a chocolate cake….

root beer extract

I wanted to flavor the icing too, and looked for root beer extract at the grocery.  No luck, but Amazon prime to the rescue!  I got it 2 days later, so handy.


I had used a similar chocolate cake mix for Chocolate Cake with Pistachio Ganache and knew it would make a perfect chocolate cake.  I used the beer for the liquid, substituted butter for the oil, added an extra egg and used root beer and vanilla extracts


I also added a splash of root beer beer to the chocolate pudding mix included in the cake mix


The dark spots are where the rich dark chocolate pudding mixed into the batter


The icing “ice cream” balls are a plain buttercream icing flavored with root beer extract


Use a small scoop and roll the thick icing gently into balls and place them on cake

Pile them all around the top of cake, pressing them gently on to the cake and each other.  Everything sort of sticks together

You can fill the center with real or maraschino cherries

with a cherry on top
