Chocolate Hazelnut Biscotti

Chocolate and hazelnut are just made for each other. It’s a flavour pairing that I’ve celebrated once before in my Chocolate Hazelnut Mousse Tart.

Chocolate Hazelnut Biscotti

In these biscotti, I unabashedly bring the two together once again, and these are amazing.

If you’ve read my earlier recipe for Cranberry Pistachio Biscotti, then you’ll know I have a fondness for these crunchy oblong treats. And I love giving them away as gifts because they’re so hardy that I never have to worry about them spoiling or falling apart.

I add a little instant coffee powder in this recipe because I think coffee enhances the flavour of chocolate. Add more coffee or replace the 1/4 cup of water with an espresso, and you’ll get a mocha biscotti. (Mm.)



220g all-purpose flour
30g unsweetened cocoa powder
1/2 tsp baking powder
1/2 tsp baking soda
100g skinned, whole hazelnuts
100g mini chocolate chips

1/2 tsp salt
200g caster sugar
1 egg
1 tsp vanilla extract
1/4 cup water (make sure it’s hot if you’re using the coffee powder)
1 tsp instant coffee powder (opt.)
1 tbsp milk

Makes about 30 biscotti.


Step 1: Tear out a piece of baking paper that will fit your sheet tray. Using a pencil and a ruler, draw two 10-inch by 2-inch rectangles about 3-inches apart. These will serve as guides for when you shape the biscotti logs. Flip the paper over and place on your sheet tray. Preheat your oven to 175°C (350°F).

Step 2: Dissolve the instant coffee powder (if using) into the hot water, and leave aside to cool. Sift the flour, cocoa, baking powder and baking soda into a large bowl. Put the hazelnuts into a resealable plastic bag and bash into small pieces with something stout like a wooden rolling pin. Add the hazelnut debris and mini chocolate chips to the dry ingredients.

Step 3: In a separate bowl, add the salt, sugar, egg, vanilla extract, cooled strong coffee (or just plain water), and milk, and stir well to combine. Add this liquid mixture to the dry and stir until a slightly stiff and sticky dough forms.

Step 4: Divide the dough equally and spoon onto the sheet tray within the two rectangular boxes you marked out earlier. Using a spoon or spatula dipped in water, flatten the top of the log and smooth out the edges.

Step 5: Bake the logs for 35 minutes. Remove the logs from the oven and cool for 10 minutes. Lower your oven temperature to 150°C (300°F).

Step 6: After 10 minutes, cut the logs into 3/4-inch slices. Lay them cut side up on the sheet tray (you may have to line it with a fresh piece of baking paper).

Bake for 10-15 minutes on each side. For softer biscotti, just bake them for 5 minutes on each side.


I deliberately over-dry my biscotti. They’re really hard and nearly almost impossible to bite. But that’s because I expect them to be dunked in a steaming mug of coffee.

I love dipping biscuits in coffee or tea or cocoa. Something about the action just seems to relax me. I know not everyone understands it. After all, what’s there to like about a soggy biscuit? Even my mum says only old men do that. “You no teeth, is it?” she’d say to me.

Well, maybe I’m just an old soul. And maybe that’s why I love making these biscottis so hard and dry – so that whoever tries them will know the simple joy of dipping a biscuit into a hot drink.
