Prepare the following icing colors:
Step 2: Using piping consistency green icing, outline the blackboard, leaving a border around the edge.
Step 3: Next, using brown piping consistency icing, pipe a border around the edge of the rectangle.
Step 4: Using piping consistency green icing, pipe some squiggles in the main part of the blackboard. This will help to give your flood some structure, so that the icing doesn't collapse as it cools. Once you have your squiggles piped, flood the inside of the blackboard with green flood consistency icing.
Step 5: Once you have your squiggles piped, flood the inside of the blackboard with green flood consistency icing.Use a scribe tool or toothpick to move the icing around to ensure full coverage. Wait for icing to dry for 30-60 minutes.
Step 6: Using brown flood consistency icing, fill in the border of the blackboard. Wait for the icing to dry about 15-20 minutes.
Step 7: Once flood icing has dried, use brown piping consistency icing to pipe a border around the edge of the cookie and around the green blackboard part of the cookie. This will give the frame of the blackboard some dimension.
Step 8: Using white piping consistency icing, pipe your message on the blackboard.
And you're done! These blackboard cookies are perfect back-to-school treats!
