Creating Peanut Butter Filled Brownie Cookies is a simple process. Follow these easy steps to achieve your sweet masterpiece:

1. Preheat Oven: Begin by preheating your oven to 350°F (175°C). Prepare a baking sheet by lining it with parchment paper.

2. Mix Dry Ingredients: In a mixing bowl, whisk together the flour, cocoa powder, baking soda, and salt. Set aside.

3. Cream Butter and Sugar: In a separate large bowl, use a mixer to cream together the softened butter and granulated sugar until light and fluffy.

4. Add Egg and Vanilla: Mix in the egg and vanilla extract, blending until smooth.

5. Combine Mixtures: Gradually add the dry ingredient mixture to the wet ingredients, mixing until just combined. If desired, fold in chocolate chips for extra chocolatey goodness.

6. Scoop Dough: Using a tablespoon or cookie scoop, take a portion of the cookie dough and flatten it in your palm. Place about ½ teaspoon of peanut butter in the center.

7. Seal the Cookie: Form the dough around the peanut butter, ensuring it’s completely encased. Roll it into a ball and then roll it in granulated sugar for an extra sweet touch.

8. Bake: Place the cookie dough balls onto the prepared baking sheet, spacing them a few inches apart. Bake in the preheated oven for 10-12 minutes.

9. Cool: Once baked, allow the cookies to cool on the baking sheet for a few minutes before transferring them to wire racks to cool completely.

10. Enjoy: Once completely cool, enjoy your Peanut Butter Filled Brownie Cookies! Watch as friends and family devour these amazing treats.
