Preheat your oven to 350 degrees F. Grease a 9x13" baking pan. Set aside.

In a large bowl, stir together flour, sugar, and baking powder. Set aside

With a pastry cutter, or in your food processor, cut the butter into the flour mixture until it resembles coarse crumbs.

Add eggs and blend well.

Press half the mixture onto the bottom of the prepared pan, and then spread the jam over the crust.

Sprinkle 1 3/4 cup of the peanut butter chips over the jam. Stir the remaining reserved crumb mixture with the remaining peanut butter chips and sprinkle over the top.

Bake for 30 to 35 minutes or until lightly browned. Cool completely in pan on a wire rack. Cut into bars.
