Real's goals came via Adam Hersh and new boy Joe Metliss.
Hersh had headed Real in front but parity was restored on the stroke of half-time when star man Ellis levelled for Bayern.
Real restored their lead with their best goal of the season - and a candidate for JC Goal of the Week. A long ball from Doron Shooter was helped forward by big centre forward Benny Goldberg. He laid it off to Lolu Hibbert who passed to Chaim Gothold who laid the ball off to Motty Korman. He played a defence-splitting pass through to debutant Joe Metliss who ran through and finished past the keeper.
But Ellis had the final say, silencing the Real fans with an injury-time leveller.
Real's Motty Korman told JC Sport: "It was a fantastic performance against an excellent and young Bayern team.
"They beat us 4-1 a few weeks ago and are a team we expect to be challenging for the title.
"We were disappointed not to have taken three points, especially as we had more chances but weren't clinical enough.
"We also felt we should have had a goal in the first half when the ball clearly crossed the line - waiting for video evidence - and also a strong penalty claim when Chaim Gothold was bundled over the in the box.
"We're very pleased with our performance against a very good team and probably the best individual player in our division, and will take the positives into our next game."
Bayern joint-manager Alon Pinhas told JC Sport: "It was probably the worst football pitch I have ever seen. Hendon had the advantage as their home pitch was extremely suitable for their style of play. We were unable to play the neat passing game that we usually play, therefore we were slightly uncomfortable today.
"We knew time was running out, with about 15 minutes to go I told all the boys to go up, attack and pile on the pressure leaving just one man back. In the final minute of added-on time, Akiva Fink put Ellis through on goal again with the keeper making a decent save to Ellis's first attempt on goal, but Ellis on the rebound with the last touch of the game headed the ball into the net and gained us a point which could be vital come the end of the season. Ellis was our man of the match today, doing his job well.
"Overall, I can't say I'm happy with a point as I know this is the worst Bayern will ever play, but it was a good sign to see my team fighting until the last moment and not losing.
"Next week we are away to Oakwood in the cup and we will definitely be up for it as we want a good cup run, and to bounce back from this weeks result."
