Line an 11x8-inch baking pan with foil, letting excess extend over sides of pan. Spray foil with cooking spray.
In a medium heavy saucepan, combine sugar, butter, milk, and salt ; bring to a boil over medium heat, stirring constantly. Boil for 5 minutes, stirring constantly. Remove from heat, and add chocolate, stirring until melted. Stir in marshmallow crème and vanilla extract until well combined. Stir in 1⁄2 cup almonds and 1⁄2 cup cherries.
Spread mixture into prepared pan. Using an offset spatula, smooth surface. Sprinkle with remaining 1⁄4 cup almonds and remaining 1⁄4 cup cherries. Let stand for several hours until fudge is firm enough to cut.
Using excess foil as handles, remove fudge from pan, and place on a cutting surface. Using a long, sharp knife, press downward to create clean cuts. Trim and discard edges of fudge. Cut into 45 (1-inch) squares.
Notes
Make-Ahead Tip: Fudge can be made up to 3 days in advance. Store in an airtight container.
