Who doesn’t love an effortless shortbread cookie? This cookie levels up shortbread cookies by at least three levels with the inclusion of a brown sugar cinnamon swirl that can actually be anything you like. (Just check out the long list of variations!) This cookie is also not your typical, crumbly shortbread texture, as this cookie has an amazing soft chew with crispy caramelized edges.
226g (1 cup / 16 Tbsp) unsalted butter, room temperature
55g (1/4 cup) brown sugar, light or dark
100g (1/2 cup) granulated sugar
1 tsp vanilla extract or paste
1 tsp Diamond Crystal kosher salt, or 1/2 tsp regular table salt
270g (2 1/4 cups) all purpose flour
55g (1/4 cup) brown sugar, light or dark
1 Tbsp ground cinnamon (I like Saigon)
1/4 tsp ground nutmeg, optional
1/2 tsp ground ginger, optional
In a small bowl, combine the ingredients for the filling. Set aside.
In a large mixing bowl, or in the bowl of a stand mixer, beat the butter until it is smooth and lump free. Add the brown sugar, granulated sugar, salt, and vanilla and mix until fully combined and slightly fluffy. Scrape down the sides and bottom of the bowl to ensure there are no under-mixed bits.
Add the flour all at once and mix on low speed until a moist, crumbly dough starts to form. The dough doesn’t need to come together as a dough ball, but will look pebbly and be easily squished into a dough between your fingers.
Sprinkle about 1/3 of the sugar filling mixture over the surface of the dough. Use your hands or a spatula to press the sugar into the dough. “Fold” the dough in half by picking up one side of the dough and pressing it into the other half. It’s okay if it’s messy and imperfect. Sprinkle the new surface of the dough with another 1/3 of the sugar filling and press it in. Fold it over again, exposing a new side of dough. Sprinkle the rest of the sugar filling, press it in, and fold it again.
Drop the dough onto a sheet of parchment paper and use your hands to press it together and form it into a log. It will resist in some places and not want to stick together, but keep working on it. It will eventually come together. Some sugar will fall out of the dough, and it will eventually cover the surface of the dough log. Make sure to really compress the log with your hands so that it won’t fall apart later. The log should be 10″ to 12″ long.
Wrap the log really well in the sheet of parchment paper before wrapping fully in plastic wrap. Refrigerate the log of dough for at least two hours or up to three days. (You could also freeze it for a few months.)
Once your dough has been properly chilled, it is time to slice and bake. Preheat the oven to 350 F and line your pans with parchment paper. Using a large chef’s knife, slice the log into cookies that are 1/4″ to 1/2″ thick. I like to cut mine slightly between the two.
Bake the cookies for 13-15 minutes if they are cut on the thinner side and 15-18 minutes if they are on the thicker side. Keep an eye on them and pull them from the oven when the tops are no longer shiny. If you like a very caramelized cookie bottom, bake them a little longer.
Let them cool on the sheet for a couple minutes before transferring them to a wire rack to cool completely. Store in an airtight container for up to a week.
This cookie is a customizable queen. She can really do anything and be anything simply by changing the filling. The ratio for the filling is roughly 55g (1/4 cup) of sugar with 1-2 Tbsp of dry flavoring. Here are some ideas:
