Ready In:
2hrs 50mins
9 Bars


  • 1 12 cups flour
  • 12 cup sugar
  • 34 cup unsalted butter
  • 14 teaspoon salt
  • 3 teaspoons super black gel food coloring
  • 8 ounces cream cheese, softened
  • 1 (14 ounce) can sweetened condensed milk
  • 14 cup lime juice
  • 1 teaspoon lime extract
  • 12 teaspoon electric green gel food coloring
  • 1 cup white candy melts to decorate cake
  • edible silver metallic spray to decorate cake
  • 1 12 cups mini green m&m candies


  • Preheat oven to 350 degrees F. Line a 9x9 inch square baking pan with parchment paper so that there is some overhang on each side. Spray with nonstick spray.
  • Add flour, sugar, butter, salt, and black gel food coloring to a food processor. Pulse until combined.
  • Press the mixture into the prepared pan. Bake for 15 minutes, then let cool in pan for 15 minutes.
  • Add cream cheese to the bowl of a standing mixer fitted with a paddle attachment. Beat until fluffy. Add sweetened condensed milk and beat. Add lime juice, extract, and green gel food coloring. Beat until combined. Pour mixture over cooled crust.
  • Bake 30-35 minutes until set. Cool 30 minutes then cover with plastic wrap and refrigerate until chilled, 4 hours to overnight.
  • Add candy melts to a microwave-safe bowl and microwave in 30 second intervals, whisking in between, until melted. Transfer to a piping bag. Pipe out 9 snakes, about 2 inches tall, onto a parchment-lined baking sheet, using a toothpick to move chocolate around. Use a printed template if needed. Refrigerate until set, about 10 minutes.
  • Once snakes are dry, spray with metallic spray and let set.
  • Lift chilled bars from pan and cut into even squares, 3 across and 3 vertical, so you have 9 squares total.
  • Push mini M&M’s into the bars in offset rows to create a snake-like pattern.
  • Pipe some melted chocolate onto the back of the snakes and place in the center of the bars. Let dry before serving.
