FAQs

1. How do I make this recipe dairy-free?

Substitute the butter with coconut oil and the milk with any plant-based milk such as almond, oat, or soy.

2. Can I use quick oats instead of rolled oats?

Quick oats will change the texture and may result in a mushier cookie. Rolled oats are recommended for the best chew.

At least 30 minutes in the refrigerator is recommended for the cookies to firm up properly.

4. Can I freeze these cookies?

Yes, freeze them in a single layer with parchment paper in between. Store in an airtight container for up to 2 months.

5. Do these cookies need to be baked at all?

No, this is a no-bake recipe. The heat from the stovetop mixture is enough to bind everything together.

6. What can I use instead of lemon juice?

You could substitute lime juice for a different citrus flavor, though lemon is preferred for the classic taste.

7. How do I know when the cookies are ready to eat?

Once they are firm to the touch after chilling, they are ready to serve.

8. Can I make these cookies sweeter or less sweet?

Yes, you can adjust the sugar to your taste or use a sugar substitute that can handle heat.

9. Will the cookies hold their shape at room temperature?

Yes, but they are best served slightly chilled to maintain firmness.

10. Can I add protein powder to this recipe?

You can mix in a scoop of unflavored or vanilla protein powder, but you may need to add a bit more milk to maintain the texture.
