Who knew miso paste worked so well in peanut butter cookies?
It might sound weird, but it’s true! These peanut butter miso cookies are the perfect balance of sweet and savory goodness. Coated in demerara sugar, every bite offer the perfect contrast of crisp exterior and chewy, peanut buttery interior. These have become my go-to peanut butter cookie and they’re sure to become yours as well!
A few notes:
- The peanut butter: Crunchy or creamy both work for these peanut butter cookies but I recommend using the unprocessed versions ( i.e. sugar and salt free). The miso actually acts as the salt in the recipe and there’s enough sugar in the dough and coating the outside of the cookie that any additional will be over kill.
- The miso: I typically use yellow miso since that’s what I’m able to find most often in my local grocery store. The original recipe recommends white miso and I’ve seen online that red works as well (note: the miso/umami flavor will be a little more intense with red miso.) Here’s a great article explaining the differences between the various pastes if you want to learn more.
- Yes, bang the baking sheet: These cookies are meant to be *thin.* Banging the baking tray on a flat surface and then letting the cookies bake a little longer releases any trapped air and ensures they bake nice and crisp.
