Begin by boiling 2 cups of water until it reaches a rolling boil. In a large mixing bowl, pour in one package of strawberry jello mix and carefully stir in the boiling water. Keep stirring until the jello is completely dissolved.

Once your jello mixture has cooled down, fold in the thawed frozen strawberries, stirring slowly to avoid breaking them apart.

Gently add one container of Cool Whip to the mixture and fold in carefully to maintain a light, fluffy texture.

Add mini marshmallows to the fluffy mixture and fold until evenly distributed.

Transfer the mixture into a serving bowl and refrigerate for at least 4 hours to set properly.

When ready to serve, scoop into bowls and consider garnishing with fresh strawberries.
