I bet cherries would be awesome, or blackberries, or pretty much any fruit, that recipe is so yum!
The oatmeal cookie mix crumble thing is super intriguing, I am so going to try something like that soon, thanks for the idea!
And yes...Honeycrisp tree definitely needs to be a thing lol!
Glad I could help a little though it doesn't seem you need any help from me! My wife is the real kitchen master of the house! She is pretty amazing.
