Preheat the oven to 350ºF (175ºC) and position an oven rack to the center position. Line 2 large baking sheets with parchment paper.
Spread the oats over a quarter baking sheet or a large pan and toast them for 9 to 10 minutes (see note 4). Let the oats cool as you prepare the dough.
Roughly crush the freeze-dried raspberries with your fingers or a mortar and pestle and then set aside.
In a bowl, whisk together the all-purpose flour, baking powder, and baking soda. Set the bowl aside.
In the bowl of a stand mixer, add the butter, miso, brown sugar, and granulated sugar. Beat on medium-low speed for about 3 minutes, until the mixture is very light and sticking to the sides of the bowl.
Scrape down the sides of the bowl. Add the egg, vanilla, and soy sauce, and mix on low until everything is incorporated, about 30 seconds. Scrape down the sides of the bowl again.
Add the flour mixture all at once and mix on low speed until just incorporated, about 15 seconds.
Set aside 22 to 25 larger chunks of chocolate. You’ll press them onto the shaped cookie dough later.
Add the rest of the chocolate, toasted oats, and crushed raspberries. Mix on low speed until everything is incorporated, about 20 to 30 seconds. To ensure that all the add-ins have been incorporated thoroughly, use a silicone spatula to scrape the bottom of the bowl and fold the dough a few times.
Grab a large ice cream/cookie scoop (see note 5) to scoop out a portion of cookie dough, using a knife or spatula to level off the top of the cookie scoop. Transfer to the lined baking sheets. There should be enough dough to make about 11 cookies.
Press 2 to 3 chocolate chunks over each ball of cookie dough. Bake the cookies one sheet at a time, for 12 to 14 minutes, until the edges are lightly golden. Make sure to rotate the pans halfway through baking to ensure even browning.
Let the cookies cool on the baking sheet for 5 minutes before transferring to a cooling rack. The cookies are very soft when the first come out of the oven, so make sure they cool slightly before transferring to a cooling rack. Store any leftover chocolate chip cookies in an airtight container for up to 4 to 5 days.
