Preheat oven to 350°F. Spray an 8x8" pan with oil and line with parchment paper so that it hangs over the edges.
Coconut Filling
In a medium bowl, mix the coconut and sweetened condensed milk together with a spatula until well combined.
Brownie Batter
In a microwave safe bowl, melt the butter and chocolate chips (stir every 30 seconds until melted, ~1-2 minutes total). Let it cool slightly (so that it doesn't cook the eggs when added in the next step).
In a large bowl, beat the eggs with a whisk for about a minute. Add the sugar and continue to whisk for another 2-3 minutes until it's slightly thick, light, and airy. Then, slowly pour in the warm butter/chocolate mixture and whisk for another minute.
In a small bowl, combine the flour, cocoa powder, and salt. Then, gently fold them into the wet ingredients just until all flour streaks are gone. The batter will be slightly thick.
Assembly
Scoop half of the brownie batter into the prepared pan and spread it around with a spatula so that it's even across the bottom.
Add the chocolate caramel squares on top of the brownie batter in an even layer.
Carefully spread the coconut filling over the chocolate caramel squares.
Finally, spread the remaining brownie batter on top of the coconut filling, covering it completely and evenly.
Bake for 30-40 minutes or until the edges begin to harden and a smooth film sets across the middle. The batter should leave behind a streak on a toothpick inserted into the middle.
Let the brownies cool in the pan until they're sturdy enough to be lifted out. Cool completely for clean cuts, or indulge while they're warm and gooey!

Notes
Recipe Update: This recipe was updated on February 1st, 2022. The sugar was decreased from 1 cup to ¾ cup and the powdered sugar was omitted from the coconut filling.Chocolate Caramel Squares: I use Ghirardelli's Milk Chocolate ones. They also make them in dark chocolate. Any brand with melted caramel in the middle should work!Coconut: Coconut flakes can work instead of shredded coconut. If they're really thick, feel free to chop them in a food processor. If you don't like coconut, you can omit the coconut and sweetened condensed milk layer.Gluten-free: These were successfully tested as gluten free by one of our readers using Bob's Red Mill Gluten Free Flour!Storage: Store brownies in an airtight container at room temperature for up to 1 week or in the freezer for 1 month.Nutrition: The provided nutrition information is an estimate, the calorie accuracy is not guaranteed.
