Biscotti dough in the Thermomix is done in a flash, it’s an absolute breeze!

‘Biscotti’ is of Italian origin. They are twice cooked biscuits, baked in a low oven. They are very crunchy and the perfect morsel to dunk in your cuppa.

Traditionally biscotti contains nuts. If you would like nuts in this biscotti, feel free to have a play around! You can replace some of the choc chips with almonds, pistachios, macadamias or pecans.

The dough isn’t overly sweet. Most of the sweetness comes from the choc chips. Because of this, it’s best to not replace all of the choc chips with nuts.

Ingredients for making Lemon Choc Chip Biscotti in the Thermomix

There isn’t a lot to these, just some basic ingredients! You’ll need the following:

biscotti ingredients in bowls - choc chips, salt, baking powder, brown coconut sugar, unbleached white spelt flour, vanilla bean, lemon, two eggs. All on wooden chopping board

Making the biscotti in the Thermomix + oven

Here is a visual guide to making biscotti. The full recipe is in the printable recipe card below.

To make biscotti, add sugar and lemon zest to Thermomix bowl.

Add remaining ingredients and combine. Scrape dough out onto a baking paper lined tray. The dough will be sticky. Use wet hands to shape into a neat log, then cook in a low oven for 30 minutes.

After 30 minutes baking, rest until cool. In the photos below, I’ve left 30 minutes and you can still it was still warm, so some of the choc chips are still melty. You can leave longer if preferred, but 30 minutes is adequate.

Lay the slices of biscotti out flat on the tray and return to the oven.

Bake a 10 minutes, then turn the slices over and bake another 10 minutes. After this time, the biscotti slices will be dry and once cooled, crunchy.

I thought biscotti would be difficult to make but it’s so easy! What a great versatile recipe this is. I added choc chips, cranberries and almonds to my batch and already have a list of combos for future batches – starting with orange, cardamom and almond!
Thanks for yet another brilliant recipe Bec.
