15-Minute Miso Rice Krispie Treats

A super simple 15 minute Miso Rice Krispie Treat recipe. Rice Krispie cereal is coated in marshmallows and brown butter flavored with white miso. It’s an effortless dessert that makes you look like you made a lot of effort.

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!

What is miso?

Miso is a thick paste made by fermenting soybeans with salt and koji. It is a popular ingredient used in Japanese cooking, and can be found in both sweet and savory Japanese dishes. It goes great on fish like in the case of miso cod or in desserts. There are many varieties of miso, and they all taste and look different depending on the fermentation process. Some are red. Some are white. (I used white miso for these rice krispie treats!) Tase-wise, it has a rich, umami, salty flavor. A little goes a long way with miso, so you only need a little bit in your dish!

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.

Ingredients, Substitutions & Adjustments

• White Miso – I used white miso for these rice krispie treats because they are sweeter than other types of miso.
• Rice Krispie cereal – This is what makes this bar a Rice Krispie treat! Rice Krispie cereal has gluten in it, so if you want to make it gluten free, make sure to get the gluten free version. The brand does make it.
• Unsalted butter – Adds a nice nutty flavor to the rice krispie treats.
• Marshmallows – Marshmallows bind the Rice Krispie cereal together. You can use either large or small marshmallows.
• Salt – As I mentioned above, salt is the key to this recipe. I tested this recipe with and without salt, and I found that salt not only brings out the flavor of the miso, but also the other ingredients in the recipe.

How to make miso rice krispie treats

First, prep a 9×9 baking pan by greasing it with butter and covering it with parchment paper. Next, add Rice Krispie cereal to a large bowl. Set aside. Melt butter until golden brown. Add the marshmallows and stir until melted. Lastly, add the white miso and salt and stir until incorporated.

Pour the miso marshmallow mixture over the Rice Krispie cereal and stir to coat. Spoon rice krispie treats into the prepared 9×9 baking dish and press down with a spatula so the rice krispie treats are distributed evenly. Let them cool for 5-10 minutes before serving.
