Coconut-Pineapple Rhubarb Bars

Directions

1. Preheat oven to 350°. In a large saucepan, combine rhubarb, pineapple, brown sugar, 1 tablespoon water and lemon juice; bring to a boil. Reduce heat; simmer, uncovered, until rhubarb is tender, 4-5 minutes.
2. In a small bowl, mix cornstarch and remaining water until smooth; stir into rhubarb mixture. Return to a boil; cook and stir until thickened, 1-2 minutes. Remove from heat; if desired, stir in extract.
3. In a large bowl, mix oats, flour, coconut, brown sugar and salt; stir in melted butter until crumbly. Press 3 cups crumb mixture onto bottom of a greased 13x9-in. baking dish. Spread with rhubarb mixture. Sprinkle with remaining crumb mixture.
4. Bake until golden brown, 40-45 minutes. Cool in pan on a wire rack. Cut into bars.
