What is the Secret to Good Shortbread?

Powdered sugar! Powdered (or confectioner’s) sugar is a blend of granulated sugar and cornstarch. The resulting shortbread is crisp and buttery, yet melts in your mouth.

Maybe it’s the Scottish blood coursing through my veins, but shortbread is my favorite of all cookies. This recipe comes from our Glaswegian neighbor who uses powdered sugar instead of granulated sugar for his Scottish shortbread recipe.

Cookie or Biscuit?

While Americans would consider a piece of shortbread a “cookie,” it’s actually called a “biscuit” outside of the US. This can be confusing since Americans consider a “biscuit” something similar to a British scone.

There are cookies in Britain, like snow cookies, but they tend to be softer and filled. Whatever you call shortbread, I just call it delicious!

I’ve written about shortbread before. My Lavender Shortbread and Rose Scented Shortbread are wonderful for special occasions.

How to Make Traditional Scottish Shortbread

Today we’re talking about the classic Scotch shortbread cookie recipe. No additional ingredients, just buttery goodness!

This shortbread recipe with powdered sugar is easy to make with just the following simple ingredients:

2 cups all-purpose flour
8 ounces unsalted butter, room temperature
3/4 cup powdered sugar
1/2 teaspoon kosher salt (don’t use table salt or it will be too salty!)
2 Tablespoons sanding sugar for dusting on cooked shortbread, optional

To make Scottish shortbread cookies, start by creaming the butter until light and fluffy. Slowly add sugar, scraping down the sides.

Mix the flour and salt together, then add it to the butter and sugar. Add flour all at once and mix just until incorporated. Do not over-mix!

Pat the shortbread into a sheet pan to get square sides. Pat it down to about 1/2″ to 3/4″ thickness. I usually make them somewhere in between.

Use a knife and cut the dough into rectangles about 2” x 1 ½”. Prick each rectangle three times. They don’t have to be perfect.

Chilling the dough at this point makes it easier to remove the shortbread from the baking sheet, and helps it keep its shape on a warm day.

Transfer the shortbread onto a parchment or silpat lined cookie sheet. Bake for 20-25 minutes at 325* F. The shortbread should be pale and light golden. Dust with sanding sugar, if desired, as soon as they are pulled from the oven.
