Yeah - grumblebee did leave out a couple of key items; temp and size of pan.
I would have gone with 350ºF and a 9x13 inch pan. But an 8x8 should have worked - although it might take a little longer to bake because it would be thicker.
The recipe did specify that you don't mix it all together and dump it into a pan ... you put half the cake batter on the botton, top with the filling, then top with the other half of the cake batter.
AND ... the last of the instructions say:

Obviously - allowing it to cool in the oven is actually part of the cooking time.
Maybe grumblebee will see this and fill in the blanks!
