First, preheat your oven to 350 degrees. Then, grease a 7 x 11 baking dish and set it aside.
Next, add the dry ingredients to a mixing bowl and stir to combine.
Then, add the wet ingredients as well as 2/3 cup of the mini chocolate chips to the bowl and stir again until just combined.
Pour the batter into your greased pan and smooth it over evenly so that the batter reaches every edge and corner of the pan.
Sprinkle the remaining 1/3 cup of chocolate chips to the surface of the brownie batter.
Bake in your preheated oven for 18-20 minutes or until a toothpick inserted down the center comes out mostly clean. (Try to avoid the chocolate chips when doing so!)
While you're waiting for the brownies to cool a bit, make your date caramel. To make the caramel sauce, simply add all of the ingredients to a high speed blender and blend until smooth.
Immediately drizzle the caramel sauce over the surface of the brownies. And then crumble coarse salt flakes over the surface, if desired! FYI - skip this step if you decide to use a jarred caramel sauce that contains salt. Otherwise, your brownies will be too salty.
