Strawberry-Rhubarb Cupcakes

In 1-quart saucepan over medium heat, cook strawberries, rhubarb, 1/3 cup granulated sugar, 1 tablespoon flour and 1 tablespoon butter, stirring frequently, until mixture comes to a boil. Reduce heat; simmer 10 minutes. Remove from heat; transfer to small bowl. Cover and refrigerate about 1 hour or until chilled.

Heat oven to 350°F. Place paper baking cup in each of 12 regular-size muffin cups. In small bowl, stir together 1 1/2 cups flour, the baking powder and salt; set aside. Reserve 2 tablespoons strawberry mixture for frosting. In another small bowl, stir together remaining strawberry mixture, 1/3 cup milk and the vanilla.

In large bowl, beat 1/2 cup softened butter and 1/2 cup granulated sugar with electric mixer on medium speed about 3 minutes or until light and fluffy. Add egg; beat until blended. Add half the flour mixture then half of the strawberry mixture, beating well after each addition. Repeat with remaining flour and strawberry mixtures. (Batter will be thick.) Divide batter evenly among muffin cups.

Bake 20 to 25 minutes or until toothpick inserted in center comes out clean. Cool 10 minutes; remove from pan to cooling rack. Cool completely, about 30 minutes.

In medium bowl, beat cream cheese, 1 tablespoon softened butter and the reserved 2 tablespoons strawberry mixture with electric mixer on low speed until smooth. Beat in powdered sugar and enough milk until frosting is of desired spreading consistency. Spread frosting on cooled cupcakes.
