Preparation Steps

• Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper.
• In a medium bowl, whisk together flour, cocoa powder, baking soda, and salt.
• In a large bowl, cream together butter and sugar until light and fluffy. Beat in the eggs one at a time, then stir in the vanilla.
• Gradually add the flour mixture to the wet ingredients, mixing until just combined.
• Drop cookie dough by tablespoonfuls onto the prepared baking sheet.
• Bake in the preheated oven for 10 minutes, or until edges are firm. Let cool on baking sheet for a few minutes before transferring to a wire rack to cool completely.
