Bake a cake, but refrain from using refined sugar, gluten, or dairy products. That was Hannah Grant's dogma when she created The Cake Cookbook. A cake cookbook based on, among other things, sweet potatoes, celeriac, and other root vegetables, which magically transform into delicious and beautiful cakes. The Cake Cookbook is already a big hit, with more than 6,000 copies sold. Whether you just want healthier cakes or have allergies, The Cake Cookbook is a fantastic companion in the kitchen.
