Step 1: Melt Chocolate and Butter: Combine dark chocolate chunks and unsalted butter in a heatproof bowl. Microwave in 30-second intervals, stirring until smooth.

Step 2: Beat Sugars and Eggs: Combine granulated sugar, brown sugar, and eggs in a large bowl. Beat on medium speed for 3-4 minutes until thick and pale.

Step 3: Combine Wet Ingredients: Stir in vanilla extract, then pour in the cooled chocolate mixture, mixing until fully incorporated.

Step 4: Mix Dry Ingredients: Sift together flour, cocoa powder, baking powder, and salt. Fold dry ingredients into the wet mixture until just combined.

Step 5: Chill the Dough: Cover the bowl with plastic wrap and refrigerate for at least 30 minutes.

Step 6: Shape the Cookies: Scoop out portions of dough, flatten, place a piece of chocolate in the center, and wrap dough around it.

Step 7: Prepare for Baking: Preheat oven to 350°F (175°C) and line a baking sheet with parchment paper.

Step 8: Bake the Cookies: Bake for 10-12 minutes; edges should be set while centers remain soft.

Step 9: Cool and Serve: Let cool on the baking sheet for 5 minutes before transferring to a wire rack.

Step 10: Enjoy the Warm Cookies: Serve warm for the best experience, optionally with a scoop of ice cream.
