Nutella Banana Cookies

1 1/2 c flour
1 c sugar
1/2 tsp baking soda
1/2 tsp salt
3/4 c shortening (I used butter flavored)
2 large mashed ripe bananas
1 egg
1 3/4 c oats
1/4 c Nutella

Preheat oven to 400 degrees.
Sift flour, sugar, baking soda and salt together in a large bowl.
Cut in shortening.
Beat in mashed bananas and egg.
Mix in oats.
Take a knife and slice Nutella into batter. Don't mix completely, so there will be pretty stripes.
Spoon drops onto parchment paper on baking sheet.
Bake 8 to 10 minutes.

Optional buttercream frosting:

1/2 c butter, softened
3 TBS milk
2 tsp vanilla
1 box powdered sugar
