This large-batch recipe makes enough cookie dough to bake some for yourself and others, and still have enough leftover to freeze for those cookie emergencies!
While the homemade condensed milk is reducing, we make our self-raising flour: mix the flour, salt, and baking powder in a large bowl.
Add 2 cups of butter, and the cup of sugar to the flour mixture and mix together thoroughly.
Then stir in the chocolate chips.
Once the condensed milk mixture is ready, pour it into the rest of the cookie batter. The hot condensed milk will melt the chocolate chips, which is what we want; it will also melt the butter which will help the cookies caramelize in the oven. Stir together until the chocolate chips are completely melted.
Let the dough sit for 10 minutes to cool off, then stir in the Reese's Pieces.
Bake in a 400 degree oven for 10 minutes. The cookies will be very soft and will need to cool for at least 10 minutes on the cookie sheet before being removed to a cooling tray.
Let cool completely before eating, and enjoy!
