• 1 1/4 cups whole-wheat pastry flour or all-purpose flour
• 1/3 cup cornstarch
• 1 1/2 teaspoons baking powder
• 1/4 teaspoon salt
• 3/4 cup sugar, divided
• 2 tablespoons butter, softened
• 2 tablespoons canola oil
• 1 large egg white
• 1 1/2 teaspoons freshly grated lemon zest
• 1 teaspoon vanilla extract
• 3 tablespoons lemon juice

Preheat oven to 350°F. Coat 2 baking sheets with cooking spray.

Whisk flour, cornstarch, baking powder and salt in a mixing bowl.

Beat 1/2 cup sugar, butter and oil in another mixing bowl with an electric mixer on medium speed until fluffy.

Add egg white, lemon zest and vanilla; beat until smooth. Beat in lemon juice.

Add the dry ingredients to the wet ingredients and fold in with a rubber spatula just until combined.

Drop the dough by teaspoonfuls, 2 inches apart, onto the prepared baking sheets.

Place the remaining 1/4 cup sugar in a saucer.

Coat the bottom of a wide-bottomed glass with cooking spray and dip it in the sugar.

Flatten the dough with the glass into 2 1/2-inch circles, dipping the glass in the sugar each time.

Bake the cookies until they are just starting to brown around the edges, 8 to 10 minutes.

Transfer to a flat surface (not a rack) to crisp.
