In a medium bowl beat the butter and sugar with an electric mixer on medium speed until combined, scraping side of bowl occasionally. Add egg; beat until combined.

Beat in as much of the flour as you can with the mixer. Using a wooden spoon, stir in any remaining flour. Stir in pecans. Set aside 1 cup of the pecan mixture for topping.

Press the remaining pecan mixture into the bottom of an ungreased 9x9x2-inch baking pan. Spread jam over crust to within 1/2 inch of the edges. Dot with the reserved pecan mixture. Bake in a 350 oven about 45 minutes or until pecan topping is golden brown.

Cool in pan on a wire rack. Drizzle with Powdered Sugar Icing or sprinkle with sifted powdered sugar. Cut into bars. Makes about 24 bars.

Powdered Sugar Icing : In a small bowl combine 1 cup sifted powdered sugar, 1 tablespoon milk, and 1/4 teaspoon vanilla. Stir in enough additional milk, 1 teaspoon at a time, to make an icing of drizzling consistency.
