Add the sunflower seed flour, coconut flour, xanthan gum and salt to a stand mixer or large bowl. Mix to combine dry ingredients.
Add the wet ingredients to the dry; softened butter, sweetener and caramel extract and blend to combine. Taste and adjust sweetener if needed.
Add the egg and mix to combine.
Place the cookie dough in the fridge for 30 minutes.
Make a batch of the sugar free caramel sauce and set aside.
Preheat oven to 350 degrees F.
Roll dough into 20 balls about 1 heaping tablespoon each and place onto a parchment paper lined baking sheet pan.
Use a rounded teaspoon to make an indent or use your thumb in the center of each cookie. Freeze for 15 minutes or overnight.
Bake for 8-10 minutes until just golden brown around the edges. If freezing overnight they will need about 15 minutes of baking time. Do not remove from sheet pan as they will be very fragile and allow to cool for at least 15-20 minutes. If they come out of the oven and have spread, gently make the indent again in center of cookies.
Place a teaspoon of caramel sauce in center of each cookie and refrigerate or allow to set on counter for 30 minutes. (**Quick tip! If your caramel separates while waiting for the cookies, simply reheat for 30 seconds then stir and it will come back together quick!)
If using optional drizzle, melt the chocolate chips and butter together. Stir well so no lumps and place in a ziplock baggie. Snip corner and drizzle over each cookie. Set on counter or refrigerate for 3 days or can be frozen for up to 3 months in an airtight container.

1 cookie with caramel sauce not including chocolate drizzle has 1 g net carbs.
