Banana Filled Peanut Butter Cookies

Cookie
1/2 cup stick margarine, room temperature
1/2 cup sugar
1/2 cup packed brown sugar
1 egg
1 tsp vanilla extract
1/2 cup crunchy peanut butter (or add 2 T chopped peanuts)
1 cup all purpose flour
1/2 cup whole wheat flour
1 tsp baking soda
1/2 tsp salt

Filling
1 tbsp margarine
1 1/2 tbsp brown sugar
1 tbsp light rum
pinch each cinnamon and nutmeg
2 small bananas, sliced
1/2 cup light cream cheese
1/2 cup smooth light peanut butter

Directions
For cookies:
Preheat oven to 350° F.
Cream together margarine and sugars until pale and fluffy.
Beat egg and vanilla, add to creamed mixture.
Stir in peanut butter.
In a separate bowl, combine flour, baking soda and salt.
Blend with peanut butter mixture.
Drop 24 balls onto an ungreased cookie sheet and press them with a floured fork.
Bake for 10 minutes. Let cool on sheet.
For filling:
In sauté pan, melt margarine.
Add sugar and increase heat to medium-high.
Stir until melted and bubbling.
Add rum, cinnamon and nutmeg.
Stir in bananas to coat, pour into a bowl and set aside.
Cream together cream cheese and peanut butter until smooth. Mash bananas and add to cream cheese mixture until smooth. Chill for 20 minutes.
Fill between 2 cooled peanut butter cookies to make sandwiches.

The alterations I plan on making to these is to use unsalted butter (I don’t use margarine). But don’t they sound incredible?
