1-First, line an 8-inch square pan with parchment paper for the green layer. Stir the neon green food coloring into the sweetened condensed milk until it’s uniformly bright, then combine it with the white chocolate chips and softened butter in a saucepan. Warm this over medium heat, stirring frequently until everything melts into a smooth mixture. Once done, stir in the green apple extract, pour it into the pan, and let it harden in the fridge.

2-Next, for the black layers, remove the hardened green fudge from the pan and parchment, then re-line the pan with fresh parchment. Mix the black gel food coloring into another can of sweetened condensed milk until it’s fully black. Heat this with the white chocolate chips and butter in a clean saucepan over medium-low heat, stirring until smooth, then add the green apple extract. Pour half of this black mixture into the pan, gently place the green fudge block on top, and spread the remaining black mixture evenly over it. Pop it in the fridge to chill until fully hardened about 12 hours!

3-Once your fudge is set, cut it into 1.5-inch blocks for about 32 bite-size pieces, and you’re all set for your Halloween party!
