Why don't your try microwaving it? it's very similar to a mock danish which I microwave every morning! I'd try putting it in a small glass (1-qt) casserole dish or loaf pan, nuke on med power for about 3-4 mins. If the center is still gooey, cook a little longer. If you're baking it at 350, I'd check it at 20 mins to see if the center is set....if not, cook a little longer!
