Bake the Grinch cookies according to package directions and allow them to cool completely.
Prepare the Santaverse Holiday cookies as directed, adding lime green food coloring to the dough before baking. Bake and cool completely.
Melt the white chocolate according to package instructions. Stir in green and yellow oil-based food coloring until you reach your desired shade.
Pour the colored chocolate into the cavities of a chocolate bar mold. Immediately sprinkle the tops with candy cane crunch, holiday sprinkles, and heart sprinkles.
Refrigerate the mold for about 30 minutes, or until the chocolate is fully set and firm. Once set, gently remove the bars from the mold and wrap each one in candy bar foil.
To assemble the gift pans, place a mix of Grinch cookies, green sprinkle cookies, and wrapped chocolate bars into each Grinch foil pan. Add any extra festive candies or chocolates if desired.
