Castagnaccio (locally also known as baldino, ghirighio or pattona) is a plain chestnut flour cake, typically found in the Tuscany, Liguria, Piedmont, Emilia-Romagna, Veneto regions of Italy, and in the French island of Corsica.
Wikipedia
This traditional rustic Tuscan chestnut flour cake is usually served in the fall and winter months following the annual chestnut harvest. However, with chestnut flour available year-round, there is no reason not to enjoy this dessert.
Unlike typical cakes and desserts found elsewhere, it is low in sugar, in fact, classic versions of this recipe do not include any form of sugar or other sweetener. Instead, they rely on the addition of dried fruit and chestnut flour to impart a bit of sweetness.
You may find castagnaccio is a bit of an acquired taste if you prefer more sugary treats.
The recipe we are sharing has a little honey added to offset the stronger, earthy flavors.
As with many Italian dishes, there are regional variations, and if this is the type of dessert you enjoy, why not experiment with different dried fruits and nuts?
Ingredients & Equipment Used In This Recipe

It may not include staple ingredients such as oil, salt, sugar, etc., as you’re likely to have those in your kitchen. The complete list of ingredients with measurements is found in the recipe card.

Recipes on The Purple Pumpkin Blog use both cup measurements and/or weighted measurements. American cups and kitchen food scales are handy pieces of equipment to have in your kitchen as it means you’ll be able to make all of the different recipes on my blog. I try to give American, imperial, and metric measurements in my recipes. Please note, you can mix cup measurements with weighted measurements, but never mix imperial (pounds, ounces, pints, etc.,) with metric (kilograms, grams, litres, etc.,).
