Directions
Prepare the Cookie Dough:

In a large mixing bowl, cream together the softened butter, peanut butter, brown sugar, and granulated sugar until light and fluffy.

Add the eggs one at a time, beating well after each addition. Mix in the vanilla extract.

In a separate bowl, whisk together the flour, baking soda, baking powder, and salt.

Gradually add the dry ingredients to the wet mixture, stirring until just combined.

Cover the dough and refrigerate for at least 30 minutes to firm up.

Bake the Cookies:

Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.

Using a tablespoon or cookie scoop, portion out the dough and roll into small balls. Place them on the prepared baking sheet, spacing them about 2 inches apart.

Flatten each ball slightly with a fork in a crisscross pattern.

Bake for 10–12 minutes, or until the edges are lightly golden.

Remove from the oven and let them cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.

Prepare the Chocolate Filling:

While the cookies are cooling, melt the chocolate in a heatproof bowl using a double boiler or microwave in 15-second increments, stirring until smooth.

If the chocolate is too thick, add the heavy cream and stir until a smooth consistency is reached.

Allow the chocolate to cool slightly but remain spreadable.
