I have been making this since my son and daughter were small. They are 40 and 38 now and still ask for my Mum Mums. I worked at a Sud shop and made these to sell. They were the best selling cookie in the shop. We love them hope you do too.
1Grease 13x9x2 pan . Slice package of cookies put in the bottom of pan pressing it in with fingers ,until it fits the pan. Mix cream cheese and eggs,sugar and vanilla. Spread over cookie dough, Slice the other cookie dough and put on top covering as much as you can. Bake at 350 for 35 mins. Cool completely and slice. Yummy.
