Pre heat oven 350 degrees F

Add all the dry ingredients (except chocolate chips) and mix together. Cut butter into small cubes and add to the mixture and mix until incorporated. Then add chocolate chips and combine. In a separate bowl, lightly mix together eggs and vanilla.

Combine the eggs into the dry ingredients and mix well until dough is formed. TIP: Use a stand mixer with dough hook (if possible).

Separate the dough into 2 loaves. Place loaves on a parchment lined baking sheet and put in oven (middle rack). Bake in oven for 20-25 minutes (adjust cooking times for your oven if necessary)

When the biscotti look light brown remove from the oven and let stand 5 minutes to cool slightly. Transfer to a cutting a board and slice across or on an angle. Approximately 1/2" wide. *Don't slice to thin or they may crumble*

Place sliced biscotti back onto the baking sheet on their side and place back into oven to continue baking for another 5-10 minutes. Flip biscotti half way through and keep an eye them so they don't over cook or burn.

When cool, if they last, store in an airtight container.
