FAQs
Can I use old-fashioned oats instead of quick oats?
Yes, but the texture will be chewier, and the cookies may not hold together as well. Quick oats absorb moisture better and create a smoother consistency.
How can I make these cookies even more lemony?
Increase the lemon zest or add ½ teaspoon of lemon extract for an extra punch of citrus flavor.
Can I use honey or maple syrup instead of sugar?
Yes, but the consistency may change. Honey and maple syrup add moisture, so you might need to adjust the oats slightly.
Do these cookies need to be refrigerated?
Not necessarily, but refrigeration helps them stay fresh longer and makes them firmer.
Can I make these cookies without butter?
Yes, you can use coconut oil or a plant-based butter alternative for a dairy-free option.
Conclusion
These lemon oatmeal no-bake cookies are a simple yet flavorful treat that's perfect for any occasion. With their bright citrusy taste and chewy texture, they’re a refreshing alternative to traditional chocolate no-bake cookies. I love how easy they are to make, and the fact that they require no baking is a huge bonus. Whether I keep them on hand for a quick snack or serve them at gatherings, they always disappear fast.
