Deliciously soft and chewy chocolate cookie cake with an easy chocolate frosting recipe. Cookie recipe from Peas and Crayons/peasandcrayons.com, and frosting recipe inspired by The Yummy Life/theyummylife.com. Notes: I used all unsalted butter in the cookie cakes and did not modify the salt amounts from the original recipes. This dough IS stiff, but the final product tastes better when made with a hand mixer.
