Ingredients:
- 1 cup (225g) unsalted butter, European style, slightly softened but cool
- 0.5 cup (60g) icing sugar, sifted
- 2 cups (250g) all-purpose flour
- 0.5 tsp fine sea salt
- 1 tsp pure vanilla bean paste
Instructions:
- Cream the Base. Beat the 1 cup of cool butter and 0.5 cup of sifted icing sugar in a stand mixer on medium low speed until a smooth, pale paste forms. Note: Stop as soon as it's smooth; we want to avoid incorporating air bubbles.
- Add Aromatics. Incorporate the 1 tsp vanilla bean paste and 0.5 tsp fine sea salt during the last 30 seconds of mixing until evenly distributed.
- Sift the Flour. Position a fine mesh sieve over the bowl and sift the 2 cups of all purpose flour directly onto the butter mixture.
- Incorporate Slowly. Pulse the mixer or use a pastry cutter to work the flour in until the dough looks like damp sand and just begins to clump.
- Form the Dough. Turn the shaggy mixture out onto parchment paper and press firmly into an 8x8 inch square baking pan until the surface is level and compact.
- The Essential Chill. Place the pan in the refrigerator for 60 minutes until the dough is cold and firm to the touch. Note: This prevents the fat from melting too fast in the oven.
- Heat the Oven. Preheat your oven to 325°F (160°C). This lower temperature is key for drying the cookie without browning it.
- Slice and Prep. Lift the dough out of the pan and slice into 24 fingers or rounds. Place them on a lined baking sheet.
- The Slow Bake. Bake for 20 minutes until the edges are a very pale mahogany and the center is set.
- Cool Completely. Leave the cookies on the hot pan for 5 minutes before transferring to a wire rack until they are fully room temperature.
