I made a half-batch to top an apple-berry pie, and it was a hit! I didn't know how it would work simply blended together like that, but I spread it over, and it came together and baked up crispy!
Thank you for a wonderful crumble topping. I made it to go with Courtly's Perfect Blackberry Pie for easter dinner at my Dad's and both were a huge hit. The only thing I omitted was the walnuts as I just don't like nuts mixed in with my food (just fine if I'm snacking them from a can or bag though)lol.
