Making these cookies is straightforward, and the process itself is a joyful experience. Here’s how to bring these sweet delights to life:

1. Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
2. In a medium bowl, whisk together the flour, cocoa powder, baking soda, and salt. Set aside.
3. In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until the mixture is light and fluffy, about 3 minutes.
4. Add the peanut butter, egg, and vanilla extract to the butter mixture. Beat until everything is well combined.
5. Gradually add the dry ingredients to the wet ingredients, mixing just until combined. Be careful not to overmix.
6. Fold in the chocolate chips and chopped peanuts (if using) until they’re evenly distributed throughout the dough.
7. Drop rounded tablespoons of dough onto the prepared baking sheet, spacing them about 2 inches apart.
8. Bake in the preheated oven for 10-12 minutes, or until the edges are set but the centers are still soft. Remember, they’ll continue to cook on the baking sheet as they cool.
9. Let the cookies cool on the baking sheet for about 5 minutes before transferring them to a wire rack to cool completely.

There’s something incredibly satisfying about seeing these cookies take shape. The aroma will fill your home with warmth and comfort, inviting everyone to gather around the kitchen.
