tablespoons holiday candy sprinkles (red and green)
Preheat oven to 375 degrees F. Line a large baking sheet with parchment paper.
Align the sweet rolls on the baking sheet, placing them close together in rows, forming a tree shape. You want to decrease the number of rolls as you go up with each row starting with one at the top, then two below, then three below, then four below, then five. Place the last roll on the bottom row in the center.
Insert a few cranberries into each roll. Bake until golden brown, about 10 to 12 minutes. Remove from the oven and let cool completely.
In a medium bowl, whisk to combine the powdered sugar, butter, vanilla, and as much milk as needed to make a smooth pourable glaze. Top each roll with the glaze and let set, about 5 minutes.
In a medium bowl, combine buttercream frosting with 2-3 drops green food coloring and mix to combine completely. Transfer to a piping bag fitted with a small tip.
Pipe the green buttercream frosting onto the tree. Place red and green candied fruit on the buttercream to decorate and top with sprinkles.
