Favorite treats or desserts from Austria?

I am Auntie Andie from Oregon and I am working on a cooking blog. I haven't created it yet but it will have recipes, a blog and video segments on how to prepare treats from around the world. Do you have a treat or dessert from your adopted home country that you think should be in my segment on your country? I'd love to hear it and try to make it. If it is the one I select I will put a short video clip of you in the segment too if you want. Send me your ideas! :-)
