Makes 12 servings

3/4 cup all-purpose flour
1/2 cup whole-wheat flour or peanut flour
1/2 cup old fashioned oats
1/2 teaspoon baking powder
1/4 teaspoon baking soda
pinch salt
1/4 cup (4 tablespoons) unsalted butter,
room temperature
1/4 cup white sugar
3/4 cup packed dark brown sugar
1/4 cup all-natural peanut butter
1 large egg
1 large egg white
1/2 cup chopped unsalted peanuts
1/4 cup semisweet chocolate chips

Preheat oven to 350°F.

In a medium bowl, combine flours, oats, baking powder, baking soda and salt. Stir with a fork to blend. Set aside.

Place butter and sugars in a large bowl; beat with a mixer at medium speed until well combined and fluffy, about 3 minutes. Add peanut butter and beat until blended. Add egg and egg white; beat until combined.

Fold in peanuts and chocolate chips. Spread mixture evenly on a 13x9x2-inch baking pan lightly rubbed with butter or sprayed with canola-based cooking spray.

Bake for 30 minutes. Cool in pan 10 minutes on a wire rack. Remove from pan, and cut into 12 approximately 4-inch long by 2-inch wide bars; let cool completely.
