Weigh your wheat berries and then grind them into your dry ingredient bowl.
Use an electric mixer or stand mixer for beating the butter, peanut butter, brown sugar, and white sugar for at least 4 to 5 minutes on medium speed.
Then add in your egg and beat for another couple of minutes.
Mix your dry ingredients in a seperate bowl.
Slowly add in your dry ingredients and mix until just incorporated. I beat it with the paddle attachment on my kitchen aid for about 30 seconds.
Chill the dough. 30 minutes to 48 hours.
Shape about 1 Tablespoon of dough into balls or use a small cookie scoop for uniform portions. Roll each dough ball in sugar before placing them on the baking sheet.
Bake for 8-10 minutes. Remove the cookies when you start to see cracking on the top of the cookie and they are golden brown, then immediately press a chocolate kiss into the top of each cookie.
Cool completely before storing. Once cool, keep them in an airtight container to maintain that chewy texture.
