Combine the ingredients together in a medium mixing bowl until completely mixed together.
Place on a parchment lined cookie sheet approximately 2 inches apart using a small cookie scoop. Press your thumb into the top creating an indent.
Prepare the caramel packet and fill each thumbprint in the cookie. You can add in a bit more so that it's over the top a bit, it doesn't have to be level.
Cool in the refrigerator for 10 minutes.
Cook for 12-15 minutes, until the edges are cooked and the middle is set.
Remove from the oven and cool on baking sheets completely.
