Preheat the oven to 350 degrees F. Line a baking sheet with parchment paper and spray with nonstick cooking spray.

For the Cookie Dough Stuffing: Using a hand mixer or a stand mixer, mix together the butter, brown sugar, and vanilla until combined. Then add the flour, protein powder, salt, and pancake syrup and mix until all ingredients are incorporated. Add the m&m's and knead the dough with your hands until the m&m's are evenly incorporated. Place the dough in the freezer to thicken while you prepare the cookies.

For the Chocolate Sprinkle Cookies: In a large mixing bowl, combine the protein powder, all-purpose flour, coconut flour, brown sugar alternative, black cocoa powder, baking soda and salt. Mix until the ingredients are combine and there are no clumps. Then add the butter, pancake syrup, and vanilla and mix with a silicone spatula until all the dry ingredients are incorporated and you have a ball of dough. Place in the freezer for 5-10 minutes so that the dough is easier to shape.

Assemble: Break the chocolate cookie dough in 8 pieces and roll into a ball with your hands. It helps to add a little water to your palms before rolling to prevent the dough sticking to your hands. For exact macros, make each cookie 28g. Once cookies are rolled out, space them a few inches apart on the baking sheet and flatten as much as you can without breaking the cookie. You can use the water on your palm trick again or use another sheet of parchment paper sprayed with nonstick cooking spray to flatten the cookies.

Take the cookie dough out of the freezer and roll into 4 large balls. Place the cookie dough balls on top of 4 of the cookies. For exact macros, use 30g.

Take remaining 4 chocolate cookie dough pieces and lay them over the cookie dough. Pick them up and pinch the sides together. Once the seams of the cookies are together, gently roll the sides to ensure it stays all together. Then flatten back out some with your palms.

Place sprinkles on a small plate and dip one side of the cookie into the sprinkles to cover. Gently press down and place back on the baking sheet, sprinkle side up. Repeat with all the other cookies and make sure to place them a few inches apart.

Bake for 8-10 minutes, then take out and transfer to a wire rack to prevent further baking. Let cool and enjoy!
