Preheat oven to 325 degrees. Line a baking sheet pan with parchment paper, or foil, sprayed with non-stick cooking spray.
In one bowl, mix together the wet ingredients. In a separate bowl, mix together the dry ingredients. Mix the wet and dry ingredients together until just combined. Fold in chocolate chips.
Spread mixture on prepared baking pan, forming a log shape with the dough. (Dough should be wet and slightly sticky, but easy enough to spread). Bake for 25 minutes.
Remove from the oven and let sit for 10 minutes. Turn the oven down to 300 degrees.
After about 10 minutes, use a large knife to slice the 'log' into 10 equal slices.
Turn each slice on their side and bake (in 300 degree oven) for another 25 minutes. Remove from oven, flip biscotti to other side, and bake for an additional 25 minutes. (Note: You may need to bake them a little longer on each side, depending on the humidity and your oven. The biscotti should be dry and crisp when done.)
When completely cooled, drizzle white or dark chocolate over the top of each biscotti, and top with a dusting of sprinkles if desired!
