Preparation

• Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
• Cream together the softened butter, granulated sugar, and brown sugar in a large mixing bowl until light and fluffy.
• Beat in the eggs one at a time and stir in the vanilla extract until well combined.
• Whisk together the flour, cocoa powder, baking soda, and salt in a separate bowl.
• Combine the dry ingredients with the wet mixture, mixing until just combined. Fold in the chocolate chips.
• Scoop out a portion of cookie dough, flatten it slightly, and add about 1 teaspoon of chocolate fudge sauce in the center.
• Seal the fudge sauce by folding the edges of the dough over it, rolling into a ball.
• Arrange the filled cookie dough balls on the prepared baking sheet, spacing them about 2 inches apart.
• Bake for 10-12 minutes, until the edges are set while the centers remain soft.
• Cool the cookies on the baking sheet for about 5 minutes before transferring to a wire rack.
• Serve warm for the best lava effect.
