I made this cake today and loved the flavor, but I seem to have trouble with loaf cakes. The cake tested done and was very brown on top. I took it out and it sunk in the middle while cooling. I just had my oven checked so I know the temp. was okay. Do you think that baking this at 325 the whole time and not turning after 15 minutes would help? What about baking at 300 to keep the top from over browning and get the middle completely cooked? I have the same trouble with banana bread so I know it is something I am not doing right. Any help would be appreciated. Thanks
