Preheat oven to 350F and line a baking sheet with parchment paper.
Mix the protein powder, flour, and baking powder together in a small bowl. Set aside.
Add the light butter, Swerve brown, Swerve granular, and vanilla bean paste to a food processor, stand mixer, or large bowl. Mix until light and fluffy.
Add the remaining dry ingredients and mix until a crumbly dough begins to form. (I used 4 pulses in the food processor.)
Remove the blade from the food processor and add the chocolate chunks. Use a rubber spatula to bring the dough together into one large ball.
Divide the dough into 8 pieces and press between your palms to flatten. Place the cookies on the parchment paper, sprinkle with salt, and bake for 7-9 minutes until the cookies are still slightly soft in the center. Transfer to a wire rack to cool the cookies.
