Optional: Raisins or semisweet chocolate chips (1 cup each)
Preheat oven to 350°. Cream butter and sugars until light and fluffy, 5-7 minutes. Beat in egg, honey and vanilla. Whisk together flour, cinnamon, baking powder and salt; gradually beat into creamed mixture. Stir in oats, Rice Krispies, nuts and, if desired, raisins or chocolate chips.
Press into a greased 13x9-in. pan. Bake until light brown, 25-30 minutes. Cool on a wire rack. Cut into bars.
