This delicious Japanese Kit Kat not only tastes like cheesecake, but is meant to be baked too! It features a cream filling with natural cheese powder and salt (that’s the secret!), and a white chocolate coating that captures the aroma of cheesecake. For ultimate enjoyment, Kit Kat recommends baking it slightly in the toaster over as well. Instructions are included in Japanese on the packaging, but in short they recommend: chilling the Kit Kats first, placing the unwrapped bars on a baking tray in a toaster oven, briefly baking them just until they turn golden, and chilling them again for optimal flavor.
