Hi Jodi! Here is a great and easy recipe for a bar cookie that I've made for years.
Chocolate Raspberry Streusel Bars

1 cup butter or margarine,softened
1 1/2 cups all-purpose flour
1 1/2 cups rolled oats (quick or old fashioned)
1/2 cup packed light brown sugar
1/2 cup sugar
1 tsp. baking powder
1/4 tsp. salt
1 1/2 cups chocolate chips
3/4 cup seedless raspberry jam ( approx.)
3/4 cup chopped nuts

Preheat oven to 350 F.Line a 9"x13"pan with
foil,extending sides over pan.Grease foil.
Combine the butter,flour,oats,sugar,brown sugar,
baking powder and salt in a medium mixing bowl.
Beat until mixture is crumbly.
Pat about 3/4 of the mixture evenly into the
bottom of the prepared pan.Reserve remaining crumbs for topping.
Spread raspberry jam over base.
Sprinkle the chocolate chips evenly over jam,and
do the same with the nuts.
Sprinkle the reserved crumbs over all,patting
it down a little so it sticks.
Bake in a 350 F. oven for 20-25 minutes until
cookies are golden brown on top.
Let cool in pan, and then using foil,lift cookie
out of pan,cut evenly into bars.
These have been favorites of mine for years.
You can put as much jam, chocolate chips,and
nuts as you like. Enjoy!
Happy Holidays!! Sharon
