For the cookie:
1 cup (227 g) unsalted butter, softened
2/3 cup (133 g) granulated sugar
1 tsp (4 g) vanilla extract
3/4 tsp (2.25 g) kosher salt
2 1/3 cups (292 g) all-purpose flour
1/2 cup (65 g) custard powder (I used Bird’s)
Vanilla Custard Butter cream, recipe below
Instructions:
- In the bowl of a stand mixer fitted with the paddle attachment, beat butter, sugar, vanilla, and slat at medium speed until creamy -about 2-3 minutes, stopping to scrape sides of bowl.
- In a medium bowl, whisk together flour and custard powder. With mixer on low speed, gradually add the flour mixture to the butter mixture until dough begins to clump together. Turn out dough onto a lightly floured surface, and shape into a disk. Wrap in plastic wrap and refrigerate until chilled, about an hour.
- Preheat ove to 350*. Line baking sheets with parchment paper.
- On a lightly floured surface, roll dough to 1/8 inch thickness. Using a 3 inch fluted round cutter, cut dough, retooling scraps until all the dough is used. Place each round onto the parchment paper 1 inch apart. If you have a cookie stamp, use it now to make a design on the cookie.
- Freeze until firm-about 10 minutes
- Bake until edges are beginning to brown. 10-12 minutes depending on your oven. Remove from pans and let cool completely on wire racks.
