Popcorn Bark

Preheat oven to 350°F. Line a large baking sheet with parchment paper and arrange graham crackers in a single layer. Bring butter and sugar to a boil over medium-high heat. Once boiling, stir and reduce to a simmer until the mixture is golden brown, which can take about 10 minutes. Pour the toffee evenly over the graham crackers and popcorn. Bake for approximately 12 minutes until the toffee is bubbling. Remove from oven and top with semisweet chocolate chips. In a glass bowl, add white chocolate and coconut oil. Microwave in 20-second intervals until melted. Scatter the melted white chocolate over the bars; decorate with red and green M&Ms.
