Preheat oven to 350F and line 2 baking sheets with parchment paper or a baking mat.
In a large bowl, combine the almond flour, sweetener, cocoa powder, baking soda, collagen, and salt. Now add in the butter, vanilla, and beaten eggs and mix together with an electric mixer.
Pour in the chocolate chips and combine with a rubber spatula (reserve some for the tops if you want pretty chocolate chip tops). The batter will be very thick.
Using a cookie scoop, scoop out 20 cookies onto the baking sheets. Flatten the tops with your fingers or a cup and press in any reserved chocolate chips. Place in the preheated oven and bake for 13 minutes.
Remove from the oven and let cool completely on the baking sheet before serving.
