Notes on the Ingredients
*Scottish shortbread recipes typically call for golden caster sugar which is not really a thing in the States. While you could use confectioners sugar as a replacement for the caster sugar, I prefer to take a good sugar like Florida Crystals Organic Pure Cane Sugar, and use a Ninja blender to pulse it into a fine powder.
**I also do the same things with Florida Crystals Organic Brown Raw Cane Sugar. You don't have to use brown sugar if you don't have have/want it. Just add the sugar amount to the regular sugar, or cut back on the sugar total if you prefer.
***Using unsalted butter? Consider using 3/4 teaspoon or up to 1 teaspoon of salt instead.
****I make oat flour by pulsing regular quick oats (oatmeal) in the blender as well. You can buy oat flour or make it.
*****The cornstarch adds a little more "melt in your mouth" feel to the shortbread. Feel free to omit and replace with oat or all-purpose flour.
Notes on the Instructions
*You can also grease a pan instead of using parchment paper. I prefer to use parchment paper and a springform pan for simple removal. Don't want them to crumble. Springform pans can be expensive, especially if you don't have 9x13 rectangular one. Two 8 inch round cake pans can also be used. On that note, you can cut the recipe in half and use one 8 inch round cake pan. The full recipe makes 32 shortbread fingers. A round cake pan will make 16 shortbread wedges.
**You can also use a food processor to mix. I don't have one, but it should work.
***Use some muscle or a food processor. You can even use your hands, but this isn't ideal because the heat from your hands will melt the butter into the dough, and the results are best if you don't do that. But do what you have to do because it'll still be delicious.
Shortbread is delicious on its own (all that butter! mmm), but it's also fantastic dipped/drizzled with things like caramel and chocolate (sounds like a homemade Twix bar, right? but *so* much better).
I topped some of these with melted caramel chips and semi-sweet chocolate.
An example of what the wedges look like if you use a round pan.
Shortbread smells amazing when baking, just ask this nose!
