Miso has been an ingredient that I’ve just fallen in love with. Ever since I added them to my Miso Chocolate Chip Cookies I’ve been experimenting with it in both sweet and savory dishes. The other day I used them in these miso rice krispie treats, and wow they were some of the best dessert bars I’ve ever made! The key to this recipe is actually the salt! The salt brings out the miso flavor and the flavor of the other ingredients, making these rice krispie treats some of the best I’ve ever tasted!

Why I used white miso for these Miso Rice Krispie Treats

White miso is made by fermenting soybeans with a large percentage of rice. The resulting miso is sweet which makes it perfect for desserts and lighter savory recipes like salad dressings. In contrast, red misos are saltier and more pungent, and yellow miso is somewhere in the middle flavor wise.
