Peanut Butter Jammers

I seem to make these every fall during back to school time.  Yummy!

1 (14-ounce) can sweetened condensed milk
1/2 cup peanut butter (better to avoid natural peanut butter for this recipe)
1 cup (2 sticks) butter
2 cups packed brown sugar
1 teaspoon baking soda
2 eggs
2 teaspoons vanilla extract
2 1/2 cups unsifted flour
3 cups rolled oats
1/2 cup jam, any flavor  (we like peach)

1.  Preheat oven to 350.  In medium size bowl, combine sweetened condensed milk and peanut butter; set aside.
2.  With mixer, beat butter in large bowl 30 seconds.  Add brown sugar and baking soda; beat until combined.  Beat in eggs and vanilla.  Stir in flour and oats adding a little at a time.
3.  Press two-thirds (about 3 1/3 cups) of the oat mixture on the bottom of an ungread 15x10 baking pan.  Carefully spread the peanut butter mixture over.  Drop jelly in small dollops (1/4 to 1/2 teaspoon each) evenly over peanut butter.  Dot the top with the remaining oat mixture.
4.  Bake 25 minutes or until top is lightly browned.  Cool.  Cut into bars.  Store covered at room temperature.
