Preheat the oven to 350 degrees and line a baking sheet with parchment paper
In a mixing bowl, add peanut butter, tahini, maple syrup, eggs, baking soda and vanilla and whisk together until smooth.
Stir the chocolate chips into the cookie batter
Pour the batter onto the prepared baking sheet into a log. Wet your fingers and gently make sure the batter is in one long oblong log shape.
Sprinkle the coarse salt over the top of the log and bake at 350 degrees for about 15 minutes
Take the cookie sheet out of the oven and slice the log into cookie bars, Once cut, separate them a bit and return the cookie sheet to the oven. Bake an additional 5 minutes.
Remove from oven, let cool at least 10 minutes and enjoy!
Notes
When you first start whisking the batter it will appear separated, just keep whisking and everything will come together to form a smooth batter.
If you want to have a crispier cookie bar, leave them in the oven a few extra minutes on the second bake.
