peanut butter miso cookies

by Brittney

Our sweet and salty peanut butter miso cookies have crispy edges, a chewy center and unbelievable flavor! The addition of miso paste gives this classic treat a rich and complex twist that is seriously addictive!

This is the type of cookie where you really can’t eat just one. They have that perfect balance of sweet and salty that instantly makes you reach for another. The secret? A few heaping spoonfuls of miso paste to give these peanut butter cookies a slight umami flavor boost and incredible depth of flavor!

baking with miso

Miso is most traditionally used in Japanese cooking to season soups and other savory dishes. But in recent years, baking with miso has become increasingly popular. After trying these cookies, it’s not hard to see why! It adds an umami flavor that can balance the sweetness in baked goods and provides an almost unidentifiable flavor boost.

what is miso?

Miso is a fermented soybean paste commonly used in Japan. It’s made by fermenting soybeans with salt and koji (a mold cultivated from grains, most often rice or barley). The delicious paste comes in a variety of textures and styles determined by the length of fermentation, type of grain used and ratio of ingredients.

Rice-based miso is the most common product found in the States and is generally found in white or red. Red miso has been fermented longer and will have a stronger flavor.

where can I find miso and what type should I use?

Depending on the type, miso flavors range from mild to quite funky. For this recipe, white miso (shiro miso) is the best choice due to its sweet and mild flavor.

We used Eden Organic Shiro Miso which we picked up at Whole Foods.

ingredients and substitutions

Aside from the miso paste, the ingredients for these peanut butter cookies are mostly pantry staples: flour, sugar, butter, egg, baking soda, salt, vanilla extract and, of course, peanut butter!

For the peanut butter, you’ll want to make sure you’re using something unsalted as the miso already adds a good bit of saltiness. I’ve used several brands of natural creamy peanut butter including Trader Joe’s and Crazy Richard’s and both batches have turned out well. Just make sure to stir the peanut butter well before measuring! That being said, if you do want to use a regular peanut butter such as Skippy or Jif, just omit the additional salt in this recipe.

And a quick note on the flour — I sometimes like to substitute half of the all purpose flour for whole wheat flour. This will give your cookies an extra bit of nuttiness without any change in texture. To make the substitution, use one cup (120 g) all purpose flour and ¾ cup (100 g) whole wheat flour.

tips and tricks to get the perfect cookies

Now let’s talk process. These cookies can be mixed up in just minutes, but there are a few things you should keep in mind to get the very best texture and flavor:

Measure your flour correctly. We highly recommend using a kitchen scale to measure flour when baking. If you decide to measure in volume, use the spoon and level method to get a more accurate amount. Lightly spoon flour into the measuring cup until it’s completely full. Then run the back of a knife over the cup to gently scrape off any excess.

Chill the dough for at least two hours before baking. This helps the cookies develop flavor and contributes to their chewy texture.

Adjust the bake time as needed. The cookies should be quite soft when coming out of the oven, but will firm up while cooling on the pan. Don’t be afraid to take them out before they’re too golden brown around the edges.

peanut butter miso cookies: FAQs

What do miso cookies taste like?

The miso won’t really be identifiable as miso, but will give the cookies a very slight umami flavor and deeper dimension, which contributes to the perfect balance of sweet and salty!

How do I store these cookies?

Store these cookies in an airtight container at room temperature for 3-4 days or for up to a week in the fridge. Baked peanut butter miso cookies can also be frozen for up to three months.

Can I use chunky peanut butter?

Yes! I prefer creamy peanut butter, but chunky can also be used if you want more texture.

Do I have to use natural peanut butter?

Nope! You can use a regular peanut butter, but make sure to leave out the salt called for in the recipe.

Description

Our sweet and salty peanut butter miso cookies have crispy edges, a chewy center and are seriously addictive!

Ingredients

  • butter 1 c (230 g)
  • dark brown sugar 1 c (200 g)
  • granulated sugar ½ c (100 g)
  • creamy unsalted peanut butter* ¾ c (190 g)
  • (stir well before measuring)
  • white miso paste ¼ c (70 g)
  • egg 1 large
  • vanilla extract 2 tsp
  • all purpose flour 2 c (240 g)
  • (spooned and leveled*)
  • baking soda 1 tsp
  • salt ¼ tsp

Instructions

  1. Cream the softened butter with the brown sugar and granulated sugar until smooth.
  2. Mix in the peanut butter and miso paste until fully incorporated.
  3. Add the egg and vanilla extract and continue beating until combined.
  4. In a separate bowl combine the flour, baking soda and salt.
  5. Gradually add the flour mixture to the wet mixture and mix until combined.
  6. Cover and refrigerate for at least 2 hours and up to several days.
  7. Preheat the oven to 350 F (180 C) and line several baking sheets with parchment paper.
  8. Using a cookie scoop or spoon, portion the dough out into balls (approximately 2 tablespoons of dough each) and place them on the prepared baking sheets 2 inches (5 cm) apart. They will flatten as they cook.
  9. Bake for 12-14 minutes or until golden brown around the edges. Let the cookies rest on the baking sheet for 10 minutes and then remove to a wire rack to cool completely.

Notes

Measuring Flour: We highly recommend using a kitchen scale to measure flour. If measuring by volume, use the spoon and level method to avoid over-measuring the flour. Use a spoon to lightly scoop flour into the measuring cup until it’s completely full. Then run the back of a knife over the cup to gently scrape off any excess.

Substituting Whole Wheat Flour: These cookies are especially delicious when using whole wheat flour! We recommend using 1 cup (120 g) all purpose flour and 3/4 cup (100 g) whole wheat flour for the perfect blend.

Peanut butter: I used a creamy natural peanut butter where the only ingredient was peanuts. Omit the salt in this recipe if using a regular peanut butter such as Skippy or Jif.
