In a separate bowl, whisk together the flour, salt, baking powder, baking soda and collagen peptides.
Dump the dry mixture into the wet mixture and mix until just combined.
Stir in the chocolate chips and chopped nuts (if using).
Cover the mixing bowl and refrigerate for 30 minutes to 1 hour so that the dough is easier to handle.
Scoop out a small portion of the cookie dough and roll it into a ball and then flatten it on the palm of your hands. Place a small caramel candy in the center. Then, roll the dough into a ball and place it on a baking tray, lined with parchment paper. By the way, it really helps to wear disposable plastic gloves in this step since it prevents the dough from getting warm and sticking to your hands.
Place this tray in the freezer for 5-10 minutes. Do not skip this step or else your cookies will spread while baking.
Then, remove the trays from the freezer and bake at 350 degrees F for about 10-12 minutes or until the cookies are golden brown and firm along the edges.
Let these cookies cool down to room temperature before digging in!

Notes
Some other add-ins include other flavors of chocolate chips, chopped nuts, pretzels, toffee bits, shredded coconut, sprinkles.
All ingredients must be at room temperature because they blend together smoothly this way.
Use browned butter for additional flavor.
Don't over-bake the cookies because that will dry them out. The cookies will continue baking in the pan as they cool from the residual heat.
If you can't find salted caramel, sprinkle a little bit of sea salt on top of the caramel candy before you finish rolling the cookie dough ball.
Read additional tips and variations above.
Leftovers can be stored in a cookie jar at room temperature for up to 2 days.
