FAQs
Can I use rolled oats instead of quick oats?

No, but it helps them set faster. Room temperature setting works fine in cooler environments.
Can I freeze these cookies?
Yes. Freeze in a single layer with parchment between and thaw before eating.
Can I make these vegan?
Yes—use vegan butter and non-dairy milk like almond or oat milk.
Why didn’t my cookies set properly?
You may not have boiled the sugar mixture long enough. Timing is crucial—boil for exactly one minute.
Can I make them more lemony?
Yes—add extra lemon zest, a drop of lemon extract, or sprinkle lemon sugar on top before setting.
What’s the best way to store them?
In an airtight container with parchment between layers. Refrigerate for up to 10 days for best texture.
