This royal, time-honored recipe (hello -- Downton Abbey -- Mrs. Patmore's near-disaster!) turned out beautifully, with the following changes: I melted a stick of butter, then brushed it onto about 8 stale hamburger buns (split, of course). Then I peeled and quartered 5 granny smith apples, then rinsed them and put them into a saucepan with 2T caster sugar and 2T butter over low heat. After about 30 mins of stirring occasionally, they became pulpy (next time I'm going to try out-and-out caramelizing them!) so I put them in a bowl and mashed them up. I then added another T butter, 3T sugar and 1/4C cream cheese, and about 2t each ginger, cinnamon, nutmeg, allspice and pumpkin pie spice. This was not too much spice, considering all that bread! Then I buttered an 8in. round casserole and pressed one layer of stale buns on the bottom VERY hard, then added half the apple puree, then another layer of buns pressing very hard, then the rest of the apples, then a final layer of buns. I put it in a 350 degree oven for about 45 mins or until the top buns were VERY dark. Then I turned it upside down on a plate and gave it about 10 mins before we dove in. My brother agreed -- heavenly!!! And it held it's shape very well, even the next day, cut like a pie! Not at all runny! A definite hit, a unique mix between a cake and a pie! Next time I might experiment with a different stewed fruit, or maybe a custard. Served with ice cream -- the BOMB!!!
