Allow the butter to soften at room temperature for easier handling. This helps create a soft and homogenous cookie dough.
In a large mixing bowl, cream together the softened butter and powdered sugar until light and fluffy. You can use a hand whisk or an electric mixer for easier blending.
Add the vanilla extract, salt, and egg, then mix thoroughly until a uniform mixture is achieved.
Gradually sift in the flour and cocoa powder, and mix with a spatula or by hand until a moldable, non-sticky dough forms.
Chop the dark chocolate and white chocolate into small pieces, then gently fold them into the dough. This will create delicious melted chocolate chunks in the cookies during baking.
Shape the dough into a large ball, wrap it in plastic wrap, and refrigerate for at least 30 minutes. This helps the cookies maintain their shape during baking.
Preheat the oven to 350°F (180°C) and line a baking sheet with parchment paper.
Remove the dough from the refrigerator and form small balls. Place them on the prepared baking sheet. Gently press them down to create flatter cookies.
Bake the cookies in the preheated oven for about 10-12 minutes, until the edges are slightly crispy, but the centers remain soft.
Let the cookies cool completely on a wire rack, then serve or store in an airtight container.
