Instructions

1. Prepare a batch of whipped cream. Chill the bowl and whisk attachment in the freezer for 5-10 minutes. Pour the heavy whipping cream into the chilled bowl and use an electric mixer to beat the heavy cream on medium-high speed until the cream starts to thicken. Slowly add the powdered sugar and continue beating on high speed until stiff peaks form. Set the whipped cream aside.
2. Beat the cream cheese using the paddle attachment until it’s completely smooth then add the sugar and vanilla extract and beat until combined.
3. Add the remaining ingredients. First beat in the marshmallow crème and continue mixing until well combined then fold in the prepared whipped cream and blend until smooth. Roughly crush 24 OREO cookies in a large Ziploc bag then fold into the batter until combined.
4. Spread the dip in a 9-inch square pan. Refrigerate for at least 1 hour.

Make the gravestones

1. Use a serrated knife to cleanly slice the graham crackers.
2. In a microwave-safe bowl, melt the white chocolate at 50% power in 30 second increments, stirring occasionally until the chocolate is melted and smooth. Add 1-2 drops of black food gel to dye and stir to combine until you reach your desired color.
3. Dip one side of the graham crackers into the white chocolate and smooth it with a knife, tap off any excess chocolate. Place on a baking sheet lined with parchment paper. Allow the chocolate to set completely.
4. Melt the chocolate in the same way you did the white chocolate and then use a small piping bag fitted with a size 3 round piping tip (optional) to write RIP on each gravestone. Allow the chocolate to set completely.

OREO gravesites: 

1. Using a food processor, grind 4-6 OREO cookies into find crumbs.
2. Create a stencil using folded parchment paper with a hole cut out or a rectangular cookie cutter. Place the stencil on top of the OREO cookie dip and spoon some crumbs over the stencil, gently pat and then carefully remove the stencil.
3. Place two edible candy eyeballs in each gravesite and then place a prepared gravestone at the top.

Decor (prepare just prior to serving)

1. Edible blood: Combine the corn syrup with a drop or two of red gel color and stir to combine until you reach the desired color.  Slowly sprinkle in powdered sugar to thicken. Drizzle over gravestones and dip.
2. Marshmallow: On a microwave-safe dish, place 4-6 large marshmallows and microwave for 10 second until marshmallow are puffy. Allow to cool to the touch. Use your fingers to pull apart and string the marshmallow over the dip, draping on the gravestone.
