What can you bake for the entire week that will help you stay in ketosis? Keto baking mixes! After baking, you can store them in the fridge. They should last up to one week. Take them with you to work, share them with your family, and snack on them anytime you feel hungry and a bit less productive. Whether you choose Brownie, Shortbread Cookie, or Snickerdoodle Cookie, there’s no need to buy additional ingredients — except for egg and butter that are already in your pantry. You see, these keto desserts are easy to prepare.
