Spray miniature (1 3/4") muffin pans with cooking spray, or line pans with paper liners and spray liners with cooking spray. Spoon brownie batter evenly into each cup, filling almost full. Bake at 350° for 19 to 20 minutes. Cool in pans 3 to 4 minutes, and then gently press a miniature candy into each baked brownie until the top of candy is level with top of brownie. Cool 10 minutes in pans. Gently twist each brownie to remove from pan. Cool on a wire rack.
