FAQs
Can I use quick oats instead of rolled oats?
Rolled oats provide a chewy texture that complements these cookies well. Quick oats can be used but may result in a softer, less chewy cookie.
How do I prevent the crumble topping from burning?
Keep an eye on the baking time and avoid overbaking. The crumble should be golden but not dark. If your oven runs hot, reduce the temperature slightly or check the cookies a couple of minutes earlier.
