Iced Whole-Wheat Sugar Cookies

To prepare cookies, weigh or lightly spoon flour into dry measuring cups; level with a knife. Whisk together flour, salt, and baking powder in a medium bowl. Beat butter, granulated sugar, and cream cheese in a large bowl with an electric mixer on high speed until light and fluffy, about 3 minutes. Add egg; beat until well blended. Add vanilla; beat until blended. Reduce mixer speed to low. Gradually add flour mixture to butter mixture; beat just until combined.

Flatten dough into a 6-inch disk; wrap with plastic wrap. Chill 1 hour.

Preheat oven to 350°F.

Roll dough to 1/4-inch thickness on a lightly floured surface. Cut out 32 cookies, using a 2- or 3-inch cutter, rerolling scraps as necessary. Place cookies 1 inch apart on baking sheets lined with parchment paper. Bake 12 minutes or until lightly browned around edges. Cool.

To prepare icing, whisk together powdered sugar, yogurt, and rind; drizzle over cookies. Sprinkle with sparkling sugar, if desired. Let stand on a wire rack until icing is set, about 15 minutes.
