In a medium saucepan, combine 2 cups of semi-sweet chocolate chips, 1 can of sweetened condensed milk, and 2 tablespoons of butter over low to medium heat. Stir continuously for about 5–7 minutes until melted and smooth.

Remove from heat and let cool slightly. Stir in 1 teaspoon of vanilla extract until evenly distributed.

Divide the mixture into two or three bowls. Add green food coloring to one bowl and mix until desired shade is achieved.

Prepare an 8x8-inch baking pan lined with parchment paper. Spoon the colored fudge into the pan, layering as desired. Smooth the top with a spatula.

Place in the fridge to set for about 2 hours or until firm.

After setting, lift the fudge from the pan and place on a cutting board. Decorate with orange and black gel, candy eyeballs, Halloween sprinkles, and crushed chocolate cookies.

Cut the fudge into squares or rectangles and serve on a festive platter.
