How To Make Remove the biscuits from the freezer and let them thaw at room temperature for 10 minutes. Preheat the oven to 375°. Prepare muffin tin with paper muffin liners. While the oven is preheating, prepare the cinnamon mixture by combining the sugar, cinnamon and salt in a medium sized bowl and set aside. Melt the butter in a small bowl and set aside. After the biscuits are slightly thawed, cut each biscuit into 9 pieces. Roll each piece in the melted butter then toss in the cinnamon mixture to coat. Place 9 pieces of the cinnamon coated dough along with 1 Tablespoon of raisins into the lined muffin tin and repeat until you have completed. Sprinkle the remaining sugar mixture evenly over the top of each muffin. Place the muffins of the center rack and bake for 22-25 minutes.
