Two different times I have tried this gluten free zucchini bread. First it's rising then it's falling. It's rising nicely, then half way through the baking I look in the oven and it's falling. Something in my recipe isn't quite correct but I am not sure what it is. Luckily the shape doesn't affect the taste. Maybe I need to cut down on the baking powder or soda? If you have any hints, please let me know. Thanks for reading and for all your comments.
