FAQs
Can I use quick oats instead of rolled oats?
Quick oats have a finer texture and will result in a softer, less structured bake. For best results, stick with old-fashioned rolled oats to retain some chewiness and shape.
How do I make this recipe vegan?
Replace the eggs with flax eggs (1 tablespoon ground flaxseed mixed with 3 tablespoons water per egg) and use a plant-based milk and coconut oil instead of butter to keep it vegan-friendly.
