1. Preheat oven to 350 degrees and line pans with cupcake liners.

2. Combine cake mix, pumpkin, eggs, oil, milk and pumpkin pie spice. Stir in chocolate chips.

3. Fill cupcake liners 3/4 full and bake for 15-20 minutes or until and inserted knife or toothpick comes out clean.

4. Let cool.

5. Frosting: Beat butter, vanilla, flour and brown sugar for at least 2 minutes. You want to give the brown sugar time to dissolve. Add powdered sugar until you reach your desired consistency. You can add milk if it becomes too thick (1-2 Tbsp) or a dash of salt to make it less sweet!

6. Pipe onto cooled cupcakes and top with mini chocolate chips.
