Preheat oven to 350 degrees

Mix butter and sugars and until light and fluffy.

Add pumpkin puree, egg and vanilla. Mix well.

Add pumpkin pie spice, baking powder, salt and flour. This should form a thick dough.

Line baking sheet with parchment paper.

Place dough on baking sheet in one large rectangle. It should look like a rectangle log with squared off edges. About half an inch tall and 4 inches wide.

Bake for 25 minutes.

Remove from oven let cool for 5-7 minutes.

Carefully create slices the width of the dough. The thickness of your slices (1/2-1 inch) will determine how many slices you have. I get about 15.

Lay slices cut side down on baking sheet.

Bake for 25 - 30 minutes

Remove from oven and allow to cool.

Melt white chocolate. I do about 1 minute in the microwave in a glass container, stirring every 20 seconds.

Once biscotti has fully cooled then add white chocolate and allow to cool again.
