Making Peanut Butter Brownie Swirl Cookies is easy when you follow these simple steps:

1. Preheat the Oven: Start by preheating your oven to 350°F (175°C). Line a baking sheet with parchment paper for easy cleanup.
2. Mix Dry Ingredients: In a bowl, whisk together the flour, cocoa powder, baking soda, and salt. Set aside.
3. Cream the Butter and Sugars: In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.
4. Add Egg and Vanilla: Beat in the egg and vanilla extract until fully incorporated.
5. Combine Wet and Dry Mixtures: Gradually mix in the dry ingredients until combined. Be careful not to overmix.
6. Add Chocolate Chips: Fold in the semi-sweet chocolate chips for an extra layer of chocolatey goodness.
7. Prepare Peanut Butter Mixture: In a separate small bowl, stir the peanut butter until smooth.
8. Swirl the Mixtures: Using a spoon, drop dollops of the brownie batter onto the prepared baking sheet. Add small spoonfuls of the peanut butter mixture on top, then using a knife or toothpick, gently swirl the two together.
9. Bake: Place the baking sheet in the preheated oven and bake for 10-12 minutes, until the edges are set but the centers remain soft.
10. Cool: Remove the cookies from the oven and let them cool on the baking sheet for about 5 minutes before transferring them to a wire rack to cool completely.

These steps will guide you in creating these incredible cookies effortlessly.
