• Mix the brownie mix, egg, water, and oil
• Spread the batter into a rectangular pan that has been lined with parchment paper
• Bake until cooked through and set out to cool for about an hour
• Once the brownie has completely cooled, pull the parchment paper up to lift the brownie out of the pan
• If you can, then pull the parchment paper off of the bottom of the brownie

Making the Eye

• Cut the tip off of the marshmallow about 1/4 inch deep
  
• To that, use frosting to attach the green M&M into the center and then dot a black dot of gel onto the M&M
• Now you can start to decorate the brownie
• Mix as much black gel as you need into your white frosting to make a silver color
• Attach the basket weave tip to a piping bag and fill it with the silver frosting

Silver Decorations

• Make a line going down the left side of the book
  
• Replace the tip with the large round tip
• Make a wavy snake on top of the line you just made and add some curves to the other 2 corners of the book
• *Note - The Hocus Pocus books actually has curled up snakes in the other 2 corners. I did not want to make the book that complicated so I kept it simple with some curved lines

Stitches

• Now, add about 1/4 of the chocolate frosting into a piping bag that has been fitted with a writing tip
  
• Use the writing tip to make stitches around the book
