Shortbread cookies are inherently simple — flour, sugar, and butter are just about the only things you need to make these rich, crumbly cookies. But like most super simple recipes, there are seemingly infinite variations, from shape to flour blend to mix-in to baking method. One thing that all shortbread cookies benefit from is a slow bake in a consistent oven. Since they’re such a crumbly cookie without much in the way of a binder, they need that time for the sugar to melt and bring everything together without getting too deeply browned. That can be challenging to achieve in a traditional oven, but the consistent and precise temperature control of the Anova Precision Oven makes it the perfect baking vessel for shortbread. Because the oven retains so much moisture, we’ve found that our shortbread cookies benefit from a relatively low ratio of butter to flour. When you make the dough in the food processor, which we find to be the easiest and most convenient method, you’ll notice that it looks kind of like a crumbly mess. However, once it is firmly packed into the baking dish, it’ll hold its shape and bake into a delightfully rich cookie that slices easily into perfect shortbread fingers. These cookies are at their best within 48 hours of baking. For longer storage, we recommend freezing in a vacuum seal or high-quality freezer bag with all of the air removed.

Slow-Cooked Shortbread
3 (1)
139
Ingredients
285 g (2 cups plus 2 tsp)
all-purpose flour
120 g (1 cup)
powdered sugar
½ tsp
fine salt
170 g (12 Tbsp)
unsalted butter, cut into ¼-inch pats, at cool room temperature
2 tsp
vanilla extract
Flaky sea salt, for sprinkling
Steps

1. Preheat the Oven and Prepare Pan

Rack
Lightly grease an 8-inch square cake pan with butter. Line the bottom and sides with a parchment paper sling.
Sous Vide Mode: Off
Steam: Off
Temp: 275°F
Heat: Rear

2. Make the Dough

Combine the flour, sugar, and salt in a food processor. Pulse 2 to 3 times to combine. Add the butter and vanilla. Continue to pulse until the butter is fully incorporated, the mixture turned slightly yellow, and has a sandy texture, about 15 pulses. It should not form into a ball and will appear dry and crumbly. Have faith.

3. Form the Dough

Pour the dough into the prepared pan, then press firmly into the pan with your hands to form a solid, even layer of dough. Sprinkle with flaky salt to taste.

4. First Bake

Rack
Transfer to the oven and bake for 20 minutes.
Sous Vide Mode: Off
Steam: Off
Temp: 275°F
Heat: Rear

5. Slice and Dock

Carefully remove the pan from the oven. Using a butter knife, cut the shortbread into 24 bars by slicing it into thirds in one direction, then into eighths the other direction. Use a toothpick to dock each bar 3 or 4 times.
