I greased the pan and still couldn't get the cake out. It doesn't say what size "cookie sheet." I assumed one with sides on it, not a flat one. "Fluffy" was a little vauge for me- stiff peaks, or foamy? Because I must say, I went with foamy and that didn't work out. It doesn't say what size can of condensed milk, either. It needs to be more specific, all around.
Excellent tasting cake. My wife even like it and that's hard to do. To save time, I have started using a can of dulce de leche instead of making it myself and have had the same great results.
I made this the other day and it was YUMMY! It took a really long time to make but it was worth it. The cake tastes very spongy and light. The caramel sauce is super sweet on its own but once you spread it on the cake and roll it back up, the caramel is soaked into the cake. Neat, huh? I put my cake into the fridge but I'm not sure if I was supposed to. This cake reminds me faintly of French Toast! I would definitely make this cake again and recommend this recipe to others.
