Preheat oven to 350 degrees Fahrenheit. Line a sheet pan (or two) with parchment paper or a silicone baking mat.
In the bowl of a stand mixer cream butter, both sugars, and peanut butter on medium speed for 3 minutes until light and fluffy.
Add egg and mix until incorporated. Scrape the sides of the bowl with a spatula.
Add the almond flour, baking soda, and kosher salt to the bowl and mix well until a cookie dough forms. The cookie dough will be soft.
Add the semisweet chocolate chips and mix just until they're dispersed throughout the dough.
Use a small portion scoop to scoop 6 to 8 cookies onto a sheet pan and bake for 12 minutes until the edges are golden brown. The middles should still look underbaked.
Let the cookies cool for at least 5 minutes before transferring to a cooling rack. Cookies set up as they cool! Repeat until all of the cookie dough is gone.
Notes
Note 1: You can omit the chocolate chips, reduce the amount, or swap them with peanut butter chips, white chocolate chips, or M&M's.
