I’m in love. I’ve got a new shortbread recipe that’s sending me over the moon. It’s a new technique for me, a new flavor, and a soft melting texture that is indescribable. And that’s coming from someone who’s made about a gazillion shortbread cookies and crusts on this blog…but this one brings me back to why I fell in love with shortbread in the first place.
Shortbread is a very old Scottish recipe renowned for its simplicity. The original formula is one part sugar, two parts butter, three parts flour, by weight.
If you’ve ever bought packaged shortbread, including the classic Girl Scout ‘Trefoils’, you might associate it with a rather bland, crisp biscuit-y cookie. It can be that, but it can also have a softer, more tender texture, which is the way I like it best. This dough is patted into a baking pan, pricked all over with a fork, and baked just until it sets, but is still pale. It’s cut into ‘fingers’ while still warm, and it melts on the tongue. If you like it more on the crisp side, you only have to bake it longer.
As I was setting out my ingredients to make this, I remembered the wonderful lemon sugar I used in my Lemon Poppy Seed Muffins. I figured why use regular sugar when I can get such lovely hit of lemon along with it? It gives this shortbread a surprisingly clear citrus flavor. I use a serrated peeler (the sharp ‘teeth’ make peeling a breeze, even soft fruit like ripe peaches) to peel the zest off of a large lemon. Then I process it with a cup of sugar until the zest is completely incorporated, It only takes a minute. The result is a slightly damp, terrifically fragrant sugar, ready for baking. This recipe calls for 1/2 cup of sugar, so you will have extra.
This recipe also uses oat flour, which, if you’ve never tried it, is super easy to make at home in a food processor or a high speed blender. Check out my post on how to make your own oat flour for all the details.
The inspiration for this shortbread came from a blog I discovered recently from the remote Shetland Islands, off the coast of Scotland. I set out to make their Shetland Shortbread out of curiosity, knowing it would be completely authentic, and to see how it differed from my usual recipe. Interestingly, their recipe uses melted butter, which is great because it’s so easy. I made a couple of adjustments, and of course used the lemon sugar, and I’m thrilled with the result.
If you’ve fallen in love with this shortbread like I have, you might want to try some of my other shortbread recipes, like my Butter Pecan Shortbread, or my Bittersweet Chocolate Chip Shortbread, for starters.

March 26, 2015 at 7:46 amWow! This has been a most amazing lemon week! I made a chocolate thumb print cookie last weekend that featued short bread, it’s so buttery and crumbly, how could any one resist! I will look for oat flour, but just in case I can’t find it, I will use the alternate method with oatmeal. Thanks for another yummy post!
