Blackberry Tea Bars

3/4 cup reduced calorie margarine

1 1/2 cups powdered sugar

2 egg whites

3/4 teaspoon almond extract

2 1/4 cups all-purpose flour, sifted

1/8 teaspoon salt

1/2 teaspoon baking soda

1/2 cup blackberry jam

Preheat oven to 350 degrees F. Spray a 9-by-13-inch baking pan with nonstick cooking spray.

In a large bowl using electric mixer on medium speed, beat together margarine, powdered sugar and egg whites.

Reduce speed to low, then blend in almond extract, flour, salt and baking soda. Do not overbeat.

Pour dough into prepared pan, smoothing top with rubber spatula. Lightly run spatula over the top of the dough to make 7 or 8 crisscrossing diagonal grooves. Fill groves with jam.

Bake in preheated oven for 20 to 25 minutes, until top is firm and edges begin to brown. Remove from oven and cool. Refill groves with jam.
