syn help pleeeease!

Could anyone accurately calculate the syn value of a 25g slice of jewish honey cake?
ive looked everywhere online but cant find it anywhere, problem is, my friend made it for me so i dont know how it was made or what exactly is in it..?!
It goes a little bit like..8 oz Margarine, 8 oz Honey, 3 Eggs, 12 oz Self Raising Flour.
Ive cut half of it up to send to work with the hubby. but Id love to enjoy it using my syns, however small the slices might be!
Thanks in advance! xx

You will find the syns for all these ingredients over in the syn values subforum - just use the search forum button at the top right of the stickies
You would need to guesstimate how many 25g slices were in the cake though. Prob high though as you are looking at about 50 syns just for the flour
