Heat oven to 400F degrees. Place oven rack in center of oven. Line baking sheets with parchment paper.
Miso Glazed Walnuts
In a small saucepan or skillet, over medium heat, whisk mirin or syrup, miso, brown sugar and ½ teaspoon cinnamon until blended. Bring mixture to a boil. Using a flexible rubber spatula fold in walnuts until completely coated. Reduce heat and continue cooking and stirring until mixture is thickened.
Spread candied walnuts out into a single layer on a lightly greased sheet of aluminum foil to cool.
Cookie Dough
In a bowl, whisk flour, cornstarch, oats, baking soda, salt and remaining ½ teaspoon cinnamon for 30 seconds or until blended. Set aside.
In the bowl of a stand mixer, or a large mixing bowl, beat butter on low for 1 minute or until smooth.
With the mixer on low, add both sugars. Blend for 1 minute on low until mixed.
Add eggs and mix until smooth.
Add dry ingredients.
Pulse the mixer until the wet and dry ingredients are incorporated. This will take about 10 pulses of the mixer (quick on-off motion) . Then mix on low until the flour disappears.
Mix in the raisins and walnuts using the pulse motion again.
Using a kitchen scale, measure out 3-ounce portions, do not compact the dough or use a cookie scoop, the cookie is meant to have a rough shape! Stack the cookie high, so it will still be thick after baking.
Place the cookies on prepared baking sheet.
Bake for 6-7 minutes or until the cookie is set and golden on top.
Transfer cookies on parchment paper to rack. Cool completely.
Notes
It's best to let cookies cool completely to set up before eating.Torani makes delicious flavored syrups that I love to cook with. I love to replace the mirin with different syrups depending on my other add ins.
