Crush the vanilla Oreos in a food processor until they turn into fine crumbs. Transfer the crumbs into a large bowl, add the softened cream cheese, and mix thoroughly with a hand mixer until well blended.
13 ounces pack vanilla Oreos, 8 ounces package cream cheese
Add the green food coloring, using about 10 drops or as many as needed to reach your desired shade, and mix again until the color is even.
10 drops green food coloring
Line a baking sheet with parchment paper. Scoop about 1 ½ tablespoons of the mixture, roll it into a ball with your hands, and place it on the tray. Repeat until all the mixture is used. Freeze the balls for about an hour.
While the truffles are freezing, melt the almond bark and red candy melts in separate microwave-safe bowls. Divide the almond bark into two bowls for easier handling when dipping.
24 ounces bar vanilla almond bark, ½ cup red candy melts
Remove the truffles from the freezer. One at a time, dip them into the melted almond bark, using two forks to flip and coat each truffle completely. Once coated, lift it out with a fork and let the excess bark drip off before placing it back on the parchment-lined tray.
20 candy eyeballs
Take a toothpick, dip it in the red candy melts, and draw thin lines starting at the bottom of the truffle and dragging upwards, making it look like veins. Leave the top center clear for the candy eye. Place the candy eye on top while the coating is still wet to ensure it sticks. Repeat for each truffle, working one at a time to keep the coating from hardening before decoration and wiping the toothpick after each eye.
Let the truffles sit for about 5 minutes until the coating is fully hardened. They're ready to serve and enjoy!
