Line a large baking sheet with parchment paper. This will prevent the cookies from sticking and make cleanup a breeze.
Place 12 graham cracker squares neatly on the parchment paper. Ensure they are spaced out enough to allow for spreading.
Cover each graham cracker square generously with marshmallow cream, using a butter knife to spread it evenly across the surface. It's important to coat the entire cracker to ensure every bite is sweet and creamy.
Top each marshmallow-covered cracker with another graham cracker square, pressing down gently to help the marshmallow stick. This step is crucial for holding everything together!
Once you’ve assembled your cookies, place the baking sheet in the refrigerator. Allow them to chill for one hour. This helps the marshmallow cream firm up slightly.
While the cookies chill, start preparing your melting chocolate by adding the chocolate wafers to a microwave-safe bowl.
Microwave the chocolate on 50% power for 1 minute. This gentle heating will help prevent the chocolate from burning.
After the minute, stir well, adding vegetable oil to give the chocolate a lovely sheen. Return to the microwave for additional 30-second intervals, stirring each time until the chocolate is silky smooth.
Using two forks or dipping tools, dip each cookie into the melted chocolate, ensuring every part is covered. This process is an absolute joy, watching those cookies transform!
Place dipped cookies back on the baking sheet, repeating the process until all are covered in chocolate.
Finally, return the baking sheet to the refrigerator and allow the chocolate to set for another hour. Once set, your Easy Copycat Girl Scout S'mores Cookies are ready to be devoured!
