Notes
This cake has a occasionally done a souffle trick. It collapses in the middle. I have not figured how to stop it or to fix it. I am not sure if you need to cook it longer or what. The problem is that you don't know if it will fall until you start to cool it. You can try turning the oven off and letting cool in the oven to prevent it from falling
Substitutions
Gluten: Gluten is a protein found in specific grains (wheat, spelt, kamut, barley, rye). Other grains are naturally gluten-free but may have cross-contact with gluten-containing grains. Look for certified gluten-free products if you need to avoid gluten. Find out more about wheat and gluten substitutions.
