Preheat oven to 350 degrees Fahrenheit. In a large bowl, mix tahini, coconut sugar, maple, vanilla extract and eggs and whisk until smooth. Add the dry ingredients in (except choco chips) and mix to combine. Gently fold in choco chips. Transfer to a lined baking pan and bake for 20-25 mins or until cooked through.
To make the salted caramel sauce, combine all ingredients in a saucepan and heat it up in low heat until smooth & creamy, for about 2 minutes and it starts to bubble a bit but not boiling. Set aside to cool down for a few minutes.
Once brownies are cooked, drizzle with caramel sauce on top and crushed nuts like walnuts. Slice into squares and enjoy!
