HOW TO ROLL COOKIE DOUGH INTO A LOG RECIPES

Steps:

• Heat oven to 350°F. In small bowl, mix sugar and cinnamon.
• In large bowl, break up cookie dough. Stir or knead in flour until well blended. (DO NOT EAT RAW COOKIE DOUGH AFTER COMBINING WITH FLOUR.) Reshape into log. Cut cookie dough into 32 (1/4-inch) slices. Shape each into ball and roll in sugar-cinnamon mixture; place 2 inches apart on ungreased cookie sheets.
• Bake 10 to 14 minutes or until edges are golden brown. Cool 1 minute; remove from cookie sheets to cooling rack.

Steps:

• Beat butter and sugar with a stand mixer fitted with a paddle attachment on medium speed until light and fluffy, about 2 minutes. Add egg and vanilla extract; beat until fully incorporated, about 1 minute. Gradually add flour and salt, beating on low speed until combined, about 2 minutes. Shape dough into 2 (12- x 1-inch) logs.
• Place sprinkles in a small, shallow, rimmed baking sheet. Roll each dough log in sprinkles, pressing gently to adhere. (Reserve any remaining sprinkles.) Wrap each log with plastic wrap; chill until firm, at least 2 hours or up to 2 days.
• Preheat oven to 350°F. Line 3 baking sheets with parchment paper. Remove 1 dough log from refrigerator, and unwrap. If needed, press some of the reserved sprinkles onto log to fully coat. Slice log into ¼-inch-thick rounds (you will have about 48 rounds). Arrange about 18 cookie rounds spaced 1 inch apart on prepared baking sheet. (Place remaining cookie rounds on prepared baking sheets, and place in refrigerator until ready to bake.) Bake cookies in 3 batches until edges are light golden, 9 to 10 minutes per batch. Remove from oven; cool on baking sheets 5 minutes. Transfer cookies to wire racks, and cool completely, about 20 minutes. 
• Meanwhile, remove second dough log from refrigerator, and repeat Step 3.
