Combined softened cookie dough and cocoa in large mixer bowl. This can be done with a mixer or with clean hands. Press dough into prepared pan.

For border, gently stir in 1 tablespoon white frosting into chocolate frosting (do not overmix- need to keep some light brown streaks for wood affect). Frost a 1-inch border around the top edges and sides. An additional tablespoon of white frosting can be added if more highlights are needed.
