THE BEST, CRISPIEST TOPPING from Chew Out Loud

This crisp topping recipe comes from Chew Out Loud. I'm reviewing the topping only, not the peach filling recipe, as I made apple crisp to go with it. Like the name says, it's very crispy, which is how I prefer a crumb topping. It's made with equal parts flour and oats, and equal parts brown and white sugar. I did use half the amount of nuts. I didn't add spices to the topping.

I grade this an A+.
