Preheat the oven to 350 degrees Fahrenheit. Spray a 12 cup Bundt pan with nonstick baking spray that contains flour. Getting into every crevice is essential to prevent sticking.
In a large mixing bowl, combine the chocolate cake mix, instant chocolate pudding mix, sour cream, eggs, oil, and cooled brewed coffee.
Beat the mixture on low speed for one minute to moisten the dry ingredients. Scrape down the sides of the bowl.
Increase the speed to medium and beat for two minutes. The batter will become thick and glossy.
Stir in the mini chocolate chips by hand using a spatula. This prevents the chips from sinking directly to the bottom of the pan.
Pour the batter into the prepared Bundt pan and smooth the top gently.
Bake for 55 to 60 minutes. A toothpick inserted into the center should come out clean or with a few moist crumbs, but no wet batter.
Remove the cake from the oven and let it cool in the pan for 15 minutes. Do not skip this rest. It allows the cake to set and pull away from the sides slightly.
Place a wire rack or a large plate over the top of the pan. Carefully flip the cake over and lift the pan away. Let the cake cool completely before adding any toppings.
In a microwave safe bowl, melt the white chocolate wafers according to the package directions. Stir until completely smooth and creamy.
Transfer the melted white chocolate to a plastic baggie. Snip a small corner off the bag. Drizzle the white chocolate in a zigzag pattern over the cooled cake.
Place the caramel bits and heavy cream in a small saucepan. Heat on low, stirring frequently, until the mixture melts into a smooth sauce.
Stir one teaspoon of coarse ground sea salt into the warm caramel.
Drizzle the salted caramel over the white chocolate. Work quickly, as the caramel begins to set as it cools.
Sprinkle the remaining one teaspoon of coarse sea salt over the top of the cake while the drizzles are still slightly tacky.
Let the cake set for about 20 minutes so the drizzles firm up before slicing.
