Give a fun twist to this classic cookie by making chocolate chip marshmallow cookies. This is a chewy sweet cookie studded with chocolate chips and filled with a gooey marshmallow.
In a bowl, whisk together the flour, cornstarch, baking powder, baking soda, and salt. Set aside.
In a large mixing bowl, cream together the butter and sugars until light and fluffy.
Add in the vanilla and eggs, and mix to distribute.
Add the dry ingredients to the bowl of egg mixture and mix until well combined. You may need to use your hands to help mix it in. The dough will be thick.
Fold in the chocolate chips.
Scoop the dough into 2 tablespoon sized scoops and place on a parchment lined baking sheet at least 2 or 3 inches apart.
Top with a halved large marshmallow. Add another 1 tablespoon of dough over the top and press to seal and hide the marshmallow away.
Bake the cookies for 10-12 minutes until the edges look set and the tops of the cookies no longer look "wet." They may appear slightly undone, but will finish cooking as they cool.
Let rest on the baking sheet for 2 minutes before transferring to the cooling rack.
Continue until all cookies have been cooked and cooled.
Notes
Recipe Tips:
Allow cookies to cool completely on baking sheet before transferring to cooling rack to prevent falling apart.
Making in Advance:
Chill dough in freezer for a short time or fridge for longer, adjusting based on desired quantity of cookies.
Consider balling out all dough on one baking sheet and chilling in fridge or freezer while baking another sheet.
