28 count package store-bought cinnamon rolls make sure to buy the kind that unravel, I found that the store brands or best choice usually unravel (Pilsbury does not unravel, it is more of a stamped cinnamon roll). I believe Aldi's cinnamon rolls unravel as well.
1 cuppowdered sugar
2Tbspplus 2 tsp milk
red gel food coloring SEE NOTE ABOUT FOOD COLORING
Preheat your oven to 400 degrees
Open your cinnamon roll packages and unravel all the cinnamon rolls.
On a quarter baking sheet, or a baking dish around 9 x 13 in size, start to twist, turn, and coil your unraveled cinnamon rolls. You want them to look intestine-y
Bake the cinnamon rolls for 10 minutes.
Meanwhile make the red frosting (aka - blood) by mixing together the powdered sugar, milk, and enough food coloring to get the red you are going for.
Drizzle the frosting over the baked cinnamon rolls.
Time to eat your Halloween Treat!
Food Coloring Note: If you only have the liquid food coloring, that will work too. However you will want to lessen the amount of milk added to frosting to just 1 tablespoon.
