Yes Virginia, there really is a connection between Communion, Coffee, and Cake.
Relationship between God and others is developed in these areas that help us grow as individuals and more in love with our God so we can share His love with others.
For I received from the Lord what I also handed on to you, that the Lord Jesus on the night when he was betrayed took bread, and when he had given thanks, he broke it, and said, "This is my body which is [broken] for you. Do this in remembrance of me." In the same way also he took the cup, after supper, saying, "This cup is the new covenant in my blood. Do this, as often as you drink it, in remembrance of me" (1 Corinthians 11:23-25).
And in Mark, written between 75-80 A.D. we read of the scene of Jesus' Last Supper:
And as they were eating, he took bread, and after blessing it broke it and gave it to them, and said, "Take; this is my body." And he took a cup, and when he had given thanks he gave it to them, and they all drank of it. And he said to them, "This is my blood of the covenant, which is poured out for many" (Mark 14:22-24).
