I picked up a mini layer cake pan set whilst in the US. Add rainy day + one box spice cake mix + homemade cream cheese frosting. Voila!
I’m surprised more people don’t use box cake mixes. You can easily fancy them up by using extra eggs, butter rather than oil, etc. (There are plenty of hacks for box cake mixes all over the internet!)
That being said, I don’t like frosting, although my attempt at a “rustic” style spice cake will not get me to the finals on GBBO anytime soon… But it should taste good!
