1Heat oven to 350°F. Grease bottoms only of 8 regular-size muffin cups with shortening or cooking spray.
2In large bowl, stir Bisquick mix, Italian seasoning, 1/4 cup of the mozzarella cheese, the Cheddar cheese and pepperoni. Stir in tomato soup and milk just until blended. Spoon batter into muffin cups, filling almost full.
3Bake 18 to 20 minutes or until toothpick inserted in center comes out clean. Immediately sprinkle remaining 1 1/4 cups mozzarella cheese on muffins to look like mummies. Place 2 olive slices close together in center of each muffin for eyes. Bake 2 minutes longer or until cheese begins to melt. Cool 5 minutes; remove muffins from pan to cooling rack. Serve warm.
