Biscotti is something I have eaten many times, but never made before. This recipe for Banana Walnut Biscotti has all the flavor of banana bread in a crispy cookie. As I was making the recipe I decided to add dried blueberries also, which were a great addition to the biscotti. The cookies are crunchy and taste strongly of the fruit and nuts, and the blueberries add quite a bit of sweetness.

How to Make Italian Biscotti Cookies

The process of making biscotti takes a little longer than most cookies, since they need to be baked twice. But the extra baking time is what gives them their characteristic crispness, and what keeps them fresh longer, so it is worth the effort.

First I shaped the dough into two long logs and baked them in the oven.

Then I cut the rolls into half inch slices and baked them again.

Since I had never made biscotti cookies before I didn’t make them exactly perfectly! I realized after I was done that I should have cut the loaves diagonally, so the biscotti were larger. But this is actually good, because now I have an excuse to make another batch and try out a different combination of flavors.

Recipe Tips

  • You could make this recipe more kid friendly by using 1/2 cup of chocolate chips instead of the dried blueberries.
  • Make sure you use a sharp, serrated knife to cut the biscotti so you don’t end up with a crumbly mess.

  1. Out of all the biscotti flavor combinations this is the first I have ever heard of banana walnut! I love banana walnut cake, but not a huge fan of banana walnut, not sure why! But this cookie sounds amazing! I will have to try this soon! Thank you for sharing!

  2. These are the perfect biscotti for me! I get so many bananas when my trees produce that I still have a freezer full of frozen bananas. What a delicious way to use some! Love your combination with the blueberries too. You couldn’t have made a better first batch!

  3. Your first photo shows exactly how I like to eat my biscotti. I’ve never tried banana in my biscotti, but I always seem to have an abundance of bananas (thanks Costco :)), and can’t wait to try these.

  4. 5 stars
    Don’t have dry blueberries, but was looking where to use the cranberries ☺let you know how it Comes out!!! Thanks for the idea

  5. I haven’t made biscotti in a really long time, but this recipe has got me motivated!Such wonderful flavors this treat 🙂

    • I didn’t roll mine out, my dough was very sticky also. I sprayed my hands with Pam and separated the dough in half put it on cookie sheet and used my fingers to work it to the 8 inch size. It worked out better this way. Hope this helped.
