This is a popular after school or lunch bag treat for all South African kids. Most South African baking is done using self-rising flour - and I highly recommend using it! The kind we get here in Canada is Brodies.
This chilly treat is an adaptation of one served at the Royale Eatery, a burger and shake shop in Cape Town, South Africa. A simple purée of avocado, ice cream, mint leaves, and ice, it's sweet, rich, and dense enough to stand a spoon in.
