Purple Sweet Potato Marble Cake

WHAT THE!!! Read on and learn how to make Purple Sweet Potato Marble Cake using a Thermomix

Some comfort food for you this winter baking and that we're still in partial restrictions so here's a yummy Purple Sweet Potato Marble Cake.

“Comfort foods are just tat so comforting, because they provide both a psychological comfort and nutritional benefit,” certified nutritionist Brian Bender says.

Often at times, these foods remind us of fond memories or occasions — birthdays and holidays, for example — connected to friends or relatives, according to Bender.

"Although comfort food will never break your heart," Gabriel says in a news release, "it might destroy your diet." But hey, this Purple Sweet Potato Marble cake is not one which you bake daily, so enjoy this especially with winter just a cold breath away. Here is the recipe generously contributed by Melanie. Melanie is a Thermomix Consultant and she has a few more bakes and recipe up her sleeve. She also conducts classes online and if you grab your thermomix from her she's more than happy/willing to guide you.
