Filling the Cake

It was difficult to split the cake lengthwise so it could be filled with the custard. I ended up cutting into 8ths and then splitting those pieces, filling them and reassembling the pieces. I think the cake should have been a little thicker, this was very thin, like a cookie sheet cake only uneven due to the rising process. Where the sugary topping pooled it didn't rise as much adding to the difficulty.
