Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.

In a mixing bowl, combine the melted butter, granulated sugar, and brown sugar. Mix well using an electric mixer or whisk until smooth.

Add in the eggs, one at a time, mixing well after each addition. Stir in the vanilla extract.

In a separate bowl, whisk together the flour, cocoa powder, salt, and baking powder.

Gradually add the dry ingredients to the wet ingredients, mixing just until combined. Be careful not to overmix.

Fold in the chocolate chips until they are evenly distributed throughout the cookie dough.

Using a cookie scoop or tablespoon, drop rounded balls of dough onto the prepared baking sheet, spacing them about 2 inches apart.

Bake in the preheated oven for 10-12 minutes, or until the edges are set and the centers look slightly soft.

Remove from the oven and allow the cookies to cool on the baking sheet for 5 minutes, then transfer them to a cooling rack to cool completely.

For an extra boost of flavor, consider adding chopped nuts or a sprinkle of sea salt on top of the cookies before baking.

Store any leftovers in an airtight container at room temperature for up to five days.

These cookies can also be served warm with a scoop of ice cream for an indulgent dessert.
