In a large mixing bowl, cream together 1/2 cup butter, 1/2 cup brown sugar, and 1/4 cup granulated sugar until light and fluffy.
1/2 cup butter, 1/2 cup brown sugar, 1/4 cup granulated sugar
Add 1 tsp vanilla extract and 1 egg to the butter-sugar mixture. Mix well until fully incorporated.
1 tsp vanilla extract, 1 egg
Gradually add 2 1/4 cups all-purpose flour, 1 1/2 tsp baking powder, and 1/2 tsp baking soda to the wet ingredients, mixing until just combined. Be careful not to overmix.
Gently fold in 1/2 cup semi-sweet chocolate chips until evenly distributed throughout the dough.
1/2 cup semi-sweet chocolate chips
Make a 5 oz dough ball and flatten it in your hand. Place two pieces of the 3.5 oz dark chocolate in the center and fold the dough around it, sealing it completely and shaping it into a round ball. Repeat this process for the remaining dough and chocolate pieces.
3.5 oz dark chocolate
Place the stuffed dough balls on a baking sheet lined with parchment paper, leaving enough space between the giant cookies to allow for spreading during baking. Refrigerate the dough balls for 1 hour. Chilling the dough helps the cookies maintain their shape during baking.
Preheat your oven to 350°F (180°C).
Bake the chilled cookies in the preheated oven for approximately 15 minutes, or until the edges are golden brown.
Remove the baking sheet from the oven and allow the cookies to cool for at least 15 minutes on the sheet before transferring them to a wire rack to cool completely.
Enjoy these giant chocolate stuffed cookies warm with a gooey chocolate center. Store any leftover cookies in an airtight container at room temperature for up to 3-4 days and preheat them lightly for the center to melt again. Enjoy!
Notes
Storage: Baked cookies can be stored for 3 to 5 days at room temperature in an airtight container. They can also be frozen for up to 3 months by allowing them to cool and transfer them to an airtight container. Thaw the cookies at room temperature and warm them lightly in the oven before enjoying them.
