The simplest, most delicious, fragrant walnut cookies are also fasting, you can adapt them for any tastes and preferences. You can definitely turn them from fasting cookies into butter cookies, instead of oil, and milk instead of water. Maybe they will be a little more fragrant, but know that it is a challenge to make it so simple, to see what they taste like. In addition, you can combine oatmeal with flour, some of the flour in these fasting cookies can be replaced with wholemeal. If you want them even more interesting you can put coconut butter instead of oil. But these are variations, below is the simple recipe for cookies with walnuts and cinnamon, a classic combination and don't go wrong with it.
I improvised these walnut cookies starting from the poppy seed lemon cookies recipe, I congratulate myself for what I managed to create below because I kept all the changes very well. They turned out so good for me, maybe not as perfectly tender as others with butter, but too good for some ordinary fasting cookies.
As a suggestion, if you do not like cinnamon flavor you can omit it or replace it with cocoa. So see how many suggestions I've already given you for a delicious fast, and another recipe for delicious fasting cookies with coconut flavor are these banana and coconut cookies, just as great.
