Ingredients
- 4 1/2 cups all purpose flour
- 1 tablespoon baking powder
- 1 tablespoon cracked black peppercorns
- 1/2 teaspoon salt
- 1 1/2 cups sugar
- 1 cup (2 sticks) unsalted butter, room temperature
- 2 tablespoons Grand Marnier
- 1 1/2 tablespoons grated lemon peel
- 2 teaspoons vanilla extract
- 4 large eggs
- Powdered sugar
Directions
- Line large baking sheet with parchment paper. Mix first 4 ingredients in medium bowl. Using electric mixer, beat 1 1/2 cups sugar and butter in large bowl until fluffy. Beat in Grand Marnier, lemon peel and vanilla. Beat in eggs 1 at a time. Mix in dry ingredients. Cover and chill just until slightly firm, about 1 hour.
- Preheat oven to 350°F. Sprinkle powdered sugar on work surface. Divide dough in half. Roll each half on sugar to 11-inch-long, 2 1/2-inch-wide log. Transfer logs to prepared baking sheet, spacing 3 inches apart. Bake until firm to touch, about 40 minutes. Cool slightly.
- Reduce oven temperature to 325°F. Transfer logs to work surface. Discard parchment paper. Using serrated knife, cut logs into 1/2-inch-wide slices. Arrange slices, cut side down, on baking sheet. Bake until dry, about 20 minutes. Cool on racks. (Can be made 3 days ahead. Store airtight.)
