    I have made this recipe twice in one weekend. It is very good. Here are some tips. Use the 9 X 13 pan but you will need to reserve only about 3/4 C of crumb mixture- otherwise there won't be enough to pack into the pan. I reserved all of the walnuts for the topping. I added 1 TSP of Vanilla and subbed nutmeg for cinnamon. Oh one more thing... I used half a jar of jam for each batch.  -  15 Mar 2009  (Review from Allrecipes US | Canada)


    These are a delicious healthy snack..... I used all applesauce in place of the butter. It makes a soft bottom crust, then i mixed 1 - 1 1/2 cups more oats into the remainder of the mix, to make it more crumbly for the top. I used rasperry jam. They're just the right amount of sweet.  -  16 Dec 2011  (Review from Allrecipes US | Canada)


    We really like these. We were looking for a healthy treat, though, so I substituted 1/2 cup applesauce for 1/2 cup of the butter. It added a really good flavor, reduced the fat, and I think helped the improve the crumbly factor other reviewers have mentioned--they stuck together just fine. However, one reviewer said she left out the sugar entirely and put tons of jam so I tried to just put half the sugar and tons of jam. It was okay but next time I'm just gonna put the sugar. Half the sugar = breakfast snack (not a problem), but all the sugar = treat (yum!).  -  21 Jan 2008  (Review from Allrecipes US | Canada)
