STEP 1: Drain Cherries and Prepare Liquid. Begin by draining the juice from the cherries into a measuring cup. Substitute this flavorful liquid for cold water in the recipe. Add enough water to the cherry juice to make it equal 1 cup.

STEP 2: Prepare Gelatin.  Follow the instructions on the gelatin box, substituting the cherry juice mixture for cold water. Stir until the gelatin powder is completely dissolved.

STEP 3: Chill.  Place the gelatin mixture in the refrigerator and allow it to chill until it begins to set, approximately 1 to 1 1/2 hours.

STEP 4: Prep the Cherries.  Slice each cherry in half.

STEP 5: Add Cherries.  Once the gelatin has partially set, gently fold the sliced cherries into the prepared gelatin mixture.

STEP 6: Incorporate Marshmallows.  Gently stir the miniature marshmallows into the cherry gelatin mixture, ensuring even distribution.

STEP 7: Add Cool Whip.  Gently fold the Cool Whip into the chilled mixture. Ensure thorough incorporation.

STEP 8: Final Chill.  Return the gelatin salad to the refrigerator and let it chill until completely firm, approximately 4 hours.

Serve and Enjoy!  Once firm, your Marshmallow Black Cherry Jell-O Salad is ready to be served. Enjoy the delightful blend of cherry flavor, fluffy marshmallows, and creamy whipped topping  in every spoonful.
