Miso Chocolate Chip Cookies
I first wondered about putting miso in cookies when a close friend mentioned trying some miso on a peanut butter and jelly sandwich. It turns out that the salty, umami flavors of miso pair perfectly with the rich sweetness of things like jam, jelly, and chocolate.
These cookies are one of those situations where salt, fat, acid, and sweetness combine to form the most decadent and satisfying flavor profile.

Since miso is so salty, these cookies do not need any salt added. Once you try these cookies, you’ll be amazed at how delicious all the flavors are together. The miso, sourdough starter, and combination of chocolate chips make the perfect cookie.
This is an adaption of my sourdough cookie master recipe. Here are some other versions of this cookie you may enjoy:

Sourdough Miso Chocolate Chip Cookies
Making cookies with a sourdough starter is all about how you mix the ingredients. The order in which you mix your ingredients is the most crucial part.
You need to mix the sourdough starter with the wet ingredients and sugar first before you add any dry ingredients. Also, I want to note that the miso is a wet ingredient too, so that needs to be mixed in with the sourdough starter.
Just follow the directions on the recipe card below, and you won’t have any problems.


As for storing the cookie dough, you can ferment the cookie dough in the fridge overnight before forming the cookie dough balls and baking.
When I make a batch of these cookies, I ferment them overnight in the fridge, then shape the dough into balls the next day. This recipe at 1x makes 20 cookies, so usually bake six, then freeze the rest of the cookie dough balls.
To bake the frozen cookie dough, you just put the frozen cookie dough ball on a parchment paper-lined sheet pan, let it sit at room temperature for about 30 minutes, then bake as usual.


Miso Chocolate Chip Cookies with Brown Butter
Since we use sourdough starter and miso in this recipe, no eggs are needed. My cookie recipe also calls for browned butter (cooked butter).
The most important part to remember when using browned butter is to allow it to cool to just above room temperature before you use it. If you dip a finger in the butter, it should not feel warm at all. You want the butter to still be liquid, but not warm to the touch.

Miso Cookies with Chocolate Chips
Okay, let’s discuss the delicious miso I used in this recipe. I used some of my homemade, one-year fermented miso that I teach students to make in my online course. I make it from lentils.

You do not have to use homemade miso, however. Store-bought miso works great in this recipe. Almost any kind of miso will do, just make sure it is plain and not flavored with anything like garlic or pepper.

Miso Cookies with Dark Chocolate Chunks
These cookies are fantastic with dark chocolate chunks and mini milk chocolate chips. However, you can change up the ingredients a bit to suit you.
If you really enjoy nuts in your cookies, for instance, you can add some pecans or walnuts. White chocolate chips are also great in this recipe. If you like crunchy texture, add in some crushed pretzels. All of these ingredients work well in these miso chocolate chip cookies.
