Instructions
Cookie Cake:
Preheat the oven to 350°F. Grease the pan. Melt the butter by microwaving for 20-30 seconds.
In a mixing bowl, stir together butter, sugar and brown sugar. Stir in egg and vanilla.
In a separate bowl, combine the flour, baking soda, baking powder and salt. Sift the flour ingredients into the sugar mixture and stir until almost combined. When it's nearly there, add the chocolate chips and combine.
Scoop the batter into the pan and use your hands to press it evenly.
Bake for 12-15 minutes. The middle will look underbaked, but the edges will be done.
Let it cool completely before removing from the pan. While you're waiting, make the frosting.
Chocolate Frosting:
Beat the butter on high for 2-3 minutes until creamy and fluffy.
Add the salt, vanilla, and cocoa powder. Beat until combined, then add the powdered sugar one cup at a time until smooth.
Once the cookie is cool, pipe the frosting onto the cake in whatever design you want!
