Slice-and-Bake Oatmeal Raisin Cookies

Preparation

1. Step 1

   Whisk both flours, baking powder, baking soda, salt, and nutmeg in a medium bowl. Using an electric mixer, beat butter and both sugars on high speed until light and creamy, 2-3 minutes. Add eggs one at a time, beating to blend and scraping down bowl between additions. Beat in vanilla.

   Step 2

   Reduce speed to low. Gradually add dry ingredients; mix just to combine. Fold in oats and raisins.

   Step 3

   Divide dough between 2 large sheets of parchment paper. Using paper as an aid, roll up each piece of dough into a 1 1/2" diameter log. Wrap in plastic; freeze for at least 4 hours and up to 3 weeks.

   Step 4

   Preheat oven to 350°F. Unwrap dough and cut into 1/2"-thick rounds (return unused dough to freezer); place 2" apart on a parchment paper-lined baking sheet.

   Step 5

   Bake cookies until edges are golden brown, 15-18 minutes. Transfer to a wire rack; let cool.

   Step 6

   DO AHEAD: Cookies can be baked 2 days ahead. Store airtight at room temperature.
