In a large bowl mix the butter and brown sugar with an electric mixer until creamy and well blended. 

Add the coffee cake mix and the cinnamon mix (2 separate packages), the orange juice, egg and vanilla

Mix just until well blended

Stir in the pistachios and dried cranberries, just until they are mixed through.

Spread the batter evenly in the baking pan and bake for 30 to 35 minutes.

The oatmeal bars will be done when they are golden brown on top and you can insert a wooden pick in the center and it comes out clean. 

While the bars are cooling, mix the confectioner’s sugar and heavy cream together. 

For fun, you can spoon the glaze into a plastic sandwich bag, cut out a corner, and pipe it across the cooled breakfast bars.
