Root Beer Float Cake Recipe - a total favorite. Light, fluffy, delicious. Make the cake ahead of time so it can be nice and cold before you frost it. Make the frosting and top right before serving! Also, I use real whipping cream rather than dream whip.
LC: This is the rootbeer cake I made, but not the frosting. It was INCREDIBLY moist and SO GOOD but never did taste rootbeer-y. Even on the second and third days. You could a TINY bit with the frosting but that's it. Still though, insanley good though.
