Simple Ube Cake With Buttercream Frosting

Seeing photos of Duchess of Cambridge looking FABULOUS and STUNNING in her purple suit today reminded me that I have an Ube Cake I need to write about. The power of purple 💜💜💜.

I just wanted a simple yellow cake actually but while gathering my ingredients I realized I didn’t have vanilla extract. I have Ube extract though so I’ve figured that’s even better.
