When modern Michelin pastry chef Su Tang crashes into the Great Jing Dynasty with a head full of macaron recipes, she opens her eyes to find herself a lowly maid sold into the Prince of Jing's estate. Others transmigrate with military tactics or medical skills, but she brings a whisk to the ancient world. She wins over the exacting prince with snow-skin pastries made from glutinous rice flour, settles political turmoil with caramel pudding, and even has the imperial kitchen's head chef chasing her for her secret soufflé recipe. Xiao Jue, the cold-faced God of War, was an "Ice Prince" who kept his distance from women. But after sneaking a taste of her tiramisu one late night, he pins her down with reddened eyes and says, "This sweet little treat... and you, too, belong to me." From the estate's little kitchen to the imperial kitchens, and from a maid everyone could bully to the capital's celebrated pastry chef, Su Tang rides on clouds of chiffon cake and turns life in the ancient world into a sugary-sweet romance with Xiao Jue's exclusive devotion.
