Preheat the oven to 350°F and line two baking sheets with parchment paper and set aside.
In a medium bowl, whisk together 1¾ cups all-purpose flour, ½ cup unsweetened cocoa powder, 1 (3.4oz.) box instant chocolate fudge pudding mix, 2 tablespoons malt powder, ½ teaspoon salt, and ¼ teaspoon baking soda. Set aside.
Cream together ½ cup salted butter, ½ cup light brown sugar , and ½ cup granulated sugar in a large bowl or stand mixer fitted with a paddle attachment and cream for 2 minutes.
Add in 1 large egg and 1½ teaspoons pure vanilla extract and beat until fully incorporated.
Add the dry ingredients and 3 ounces whole milk , alternating between them 3 times, beginning with flour and ending with milk. Mix for about 1 to 2 minutes The dough should be thick but soft, greasy but not sticky.
Use the scoop to measure the dough into 15 portions (about 2oz. each).
Press your thumb into the center of each ball of dough and then press one of the 16 Cadbury Caramello Miniatures into each well. Work the dough up and around the chocolate and seal well.
Add 1 cup mini chocolate chips to a small prep bowl and press the tops of the balls into the bowl to coat them with the mini chocolate chips.
Place the cookie dough balls on the prepared baking pan at least 2 inches apart and gently press the chocolate chips into the top of the dough to secure any that may be loose. I can fit 12 of these cookies comfortably on a 12x17-inch pan for reference.
Sprinkle the tops of the cookies with coarse sea salt.
Bake for 7 to 9 minutes until the edges are just set and the dough looks more matte than glossy.
Allow the cookies to cool on the pan for 15 minutes before transferring them to a wire rack with a spatula to cool completely. Bake the other pan of cookies. These cookies are very soft right after baking and will firm up while they cool.
