Prepare the glass: Chill a martini glass. Place chocolate syrup on a plate and rim the edge of the glass. Take 2-3 Halloween Oreos with the orange cream filling and crush them up. Dip the rim of the glass in the crushed Oreos and set aside.

Mix the cocktail: Add the vanilla vodka, white chocolate liqueur, crème de cacao, half-and-half or milk, and ice to a cocktail shaker.

Make it orange: Add a small amount (2-3 drops) of orange food coloring and shake until the color is vibrant and everything is well combined. Add more drops until your desired orange color.

Strain: Drizzle chocolate sauce on the inside of the glass and strain your cocktail into the prepared glass.

Garnish: Add a Halloween Oreo to the rim right before serving.
