1. Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper. This step always reminds me of the anticipation I felt as a child, waiting for the aroma of baked goods to fill our home.
2. In a medium bowl, whisk together the flour, cocoa powder, baking soda, and salt. Set aside.
3. In a large bowl, cream the butter, granulated sugar, and brown sugar together until light and fluffy, about 3-4 minutes.
4. Add the egg and vanilla extract, mixing until well combined. This is where my abuela’s advice comes into play—listen to your batter, she would say, it’ll tell you when it’s ready.
5. Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
6. Take a small amount of dough, about a tablespoon, and flatten it slightly. Add a teaspoon of peanut butter in the center, then fold the dough around the peanut butter to encase it completely. Roll gently to form a ball.
7. Place the dough balls on the prepared baking sheets, leaving space between each cookie.
8. Bake for 10-12 minutes or until the edges are set, but the centers are still soft. This is key for that perfect, chewy texture.
9. Allow the cookies to cool on the baking sheets for 5 minutes before transferring them to a wire rack to cool completely.

These cookies are best enjoyed with a glass of milk or your favorite coffee, reminiscent of the many afternoons spent at my grandmother’s kitchen table, sharing stories and laughter over homemade treats.
