These are not a typical chocolate cookie! They're made from a delicious chocolate batter, but cooked in a waffle maker so they achieve a criss-cross pattern. When finished, they're dipped in chocolate and topped with any number of decorations!
Make the batter: In a large bowl, mix together the butter, sugar, eggs, and vanilla extract. Sift in the flour, cocoa, and salt. Mix until no dry streaks remain.
16 tablespoons (2 sticks) unsalted butter, 1 ½ cups granulated sugar, 4 large eggs, 1 teaspoon vanilla extract, 2 cups all-purpose flour, ½ cup Dutch-process cocoa powder, 1 teaspoon kosher salt
Bake: Grease the preheated waffle iron and spoon in heaping teaspoons of batter. Depending on the size of the waffle iron, 2-4 can be made at a time. Let bake until crispy on the edge but soft in the center, 2-5 minutes depending on the waffle maker. It could take a few tries to figure out the baking time. Remove cookies and continue greasing and baking.
While baking, make the chocolate topping: In a medium bowl, combine the chocolate and coconut oil. Using 50% power, melt in the microwave in 30-second increments. Stir and repeat until melted, 2 minutes.
