Peanut Butter and Chocolate Layered Biscotti

Peanut Butter Chocolate Layered biscotti.
Last year it felt like my job was conspiring to keep me from enjoying the holidays. The time I so desperately wanted to use for shopping and baking was sucked into a vortex of powerpoint, taking my holiday cheer with it.  So this year, when faced with a free Saturday and a kitchen stocked with butter, flour and sugar, I knew a bit of a baking marathon was in order, especially with the deadline for The Great Blogger Cookie Swap fast approaching.  I ended up making four batches of cookies, one for the swap (which I’ll be posting about on December 12 along with all of the other participating bloggers) and three for Operation Baking Gals.

For the latter I sent off some of Martha Stewart’s Sugar Cookies, one of my favorite classic cookie recipes.

Also included in the box were two new recipes, including these Peanut Butter and Chocolate Layered Biscotti.

Made of peanut butter and chocolate biscotti dough sandwiched together, they’re elegant looking and loaded with lots of peanut butter and chocolate chips for decadent flavor.  I’ve always found that just about anything you can bake with peanut butter and chocolate is a hit and these biscotti are no exception.  They also travel incredibly well, that is if you can get your hands out of the cookie tin long enough to send them.

Peanut Butter and Chocolate Layered Biscotti
Adapted from King Arthur Flour
Yields approximately 2 dozen biscotti


-6 tablespoons unsalted butter, room temperature
-2/3 cup granulated sugar
-1/4 teaspoon salt
-1 1/2 teaspoons baking powder
-2 teaspoons vanilla extract
-2 large eggs
-2 cups all-purpose flour
-2 tablespoons cocoa powder, ideally Dutch-process
-1/3 cup peanut butter chips
-1/3 cup smooth peanut butter
-1/3 cup semi-sweet chocolate chips
-1/3 cup roasted peanuts
-2 tablespoons coarse sugar


Preheat the oven to 350 degrees F. Line a large baking sheet with parchment paper.

In a medium-sized bowl, beat the butter, sugar, salt, vanilla, and baking powder until the mixture is smooth and creamy.

Beat in the eggs; the batter may look slightly curdled, but this is okay.

Using the mixer set to low speed, add the flour, stirring until smooth; the dough will be sticky.

Divide the dough in half, leaving half in the bowl and placing the other half in a separate bowl. To one half of the dough add the cocoa powder and peanut butter chips and stir just until well distributed.

To the other half of the dough add the peanut butter, semi-sweet chips and peanuts and stir until just combine.

Shape the peanut butter dough on the pan into a log that’s about 14″ long x 2 ½” wide. Straighten the log, and smooth its top and sides using a wet spatula or wet bowl scraper.

Using your wet fingers, spread the chocolate dough atop the peanut butter dough. Sprinkle coarse sugar over the top of the dough.

Bake the dough in the preheated oven for 25 minutes. Remove it from the oven, and allow it to cool to room temperature, about 10 to 25 minutes.

While the biscotti are cooling slightly, reduce the oven temperature to 325 degrees F.

Use the parchment to lift the biscotti off the sheet onto a flat surface. Using a serrated knife or sharp chef’s knife, cut the biscotti crosswise into 3/4″ slices.

Set the biscotti, on edge, back on the baking sheet. Return the biscotti to the oven, and bake them for 30 to 40 minutes, till they feel very dry and are beginning to turn golden. They’ll still feel a tiny bit moist in the very center, if you break off a piece; but they’ll continue to dry out as they cool.

Remove the biscotti from the oven, and transfer them to a rack to cool.

Yum! This looks like the perfect recipe for me. They are beautiful!

It all looks delicious! I’ve always wanted to make biscotti and have to try this recipe soon. Thanks.

Pam – I would definitely recommend trying biscotti making, even if you only do it once. They get such a reputation for being high maintenance but really other than requiring slicing and an extra bake, they are really easy.

These sound fantastic, Kelly! I’d love if some were to travel my way 🙂

Wow those look so pretty and delicious, Kelly! Will you be sending this to anyone? I envy the lucky person!

Sophia – I did. I sent them to a soldier stationed overseas. I’ve never met him before so I hope he likes them. It’s always a little nerve wracking to bake for someone when you have no idea what their personal tastes and preferences are. I try to stick to things that I think are basic, crowd pleasers, but you never know. 🙂

Thank you so very much for posting this recipe. I make a regular biscotti for a close friend who loves it but can’t bake. She recently lost her dad & asked if I could make some with chocolate. I decided on this one because it also combined 1 of her other favorite flavors. This was a big hit & she absolutely loved it. It was fairly easy to make & came out excellent.

Suzy – Thanks so much for the feedback. I always enjoy hearing how my recipes perform in other people’s kitchen. I’m so sorry to hear about your friend’s loss but really believe in the power of food to connect people and help heal. I know I’m always incredibly awkward when it comes to loss. I’m always afraid of doing or saying the wrong thing, but food can be an easy way to show someone how much I care. Thanks again for your comment.

I don’t deal with loss really good either. My kitchen is where I find solace though. It is even better when you add my 3 girls in the mix. The love of food & the ability to share does such incredible stuff. :O)
