To a medium-size bowl, add peanut butter, maple syrup, and sea salt, and mix it with a fork until smooth. Then add almond flour and combine it into a thick dough. Fold in chocolate chips and transfer them to the prepared pan. Press the dough to the pan (use the bottom of the measuring cup or glass to flatten it and smooth the top). Make sure to get it all the way into the corners of the pan. Refrigerate while making the salted caramel.
