Mostaccioli napoletani are diamond-cut Neapolitan spice cookies built on a honey dough loaded with cinnamon, cloves, candied orange peel, and toasted almonds, then dipped in a dark chocolate glaze that dries to a matte shell. They’re a Christmas staple in Naples, sold by the kilo in every pasticceria from late November on.
The dough itself isn’t sweet the way a sugar cookie is. Honey and a modest amount of sugar carry most of that job, while the spice mix, cinnamon, clove, nutmeg, a whisper of black pepper, does the heavy lifting on flavor. Candied orange peel and almonds add chew and crunch against a dense, almost bread-like crumb.
I bake these every December and the one thing that trips people up is rolling the dough too thin. At 1.5 cm the diamonds bake through without drying out. Any thinner and you get something closer to biscotti.
The chocolate glaze sets at room temperature in about 30 minutes, so plan for that when you’re timing a cookie tray for guests.
Why You’ll Love This Recipe
- Keeps for weeks in a tin, so it’s ready before guests arrive
- Uses pantry spices, no fancy equipment beyond a rolling pin
- Egg-free dough that’s forgiving for first-time cookie bakers
- Dark chocolate glaze sets on its own, no tempering required
Ingredient Notes
- Flour: Plain all-purpose flour gives the dough structure without making it cakey. Weigh it if you can, packed cups run heavy.
- Honey: Warm it gently with the sugar and milk so it blends in without seizing the dough. Any neutral honey works, avoid strong buckwheat honey which can overpower the spices.
- Baking powder: Traditional bakers use ammonium bicarbonate for a drier, snappier crumb. Baking powder is the easier home swap and still gives good lift.
- Candied orange peel: Sub finely chopped candied citron or dried apricot if peel is hard to find. It adds chew, not just sweetness.
- Almonds: Toast them whole before chopping. Raw almonds turn soft in the dough instead of staying crunchy.
- Milk: Moscato, leftover espresso, or even orange juice can replace the milk here, each shifts the flavor slightly toward the sweeter or more bitter side.
- Dark chocolate: Use a 60 to 70% bar you’d eat on its own. Cheaper compound chocolate sets shinier but tastes flat against the spiced dough.
Mostaccioli Napoletani: Spiced Chocolate-Glazed Cookies
Ingredients
Method
- Toast the chopped almonds in a dry 10-inch skillet over medium heat for 3 to 4 minutes, stirring, until fragrant. Set aside to cool.
- In a large bowl, whisk together the flour, cocoa powder, baking powder, cinnamon, cloves, nutmeg, black pepper, and salt.
- In a small saucepan, warm the honey, sugar, and milk over low heat for 2 to 3 minutes, stirring, just until the sugar dissolves. Do not let it boil.
- Pour the warm honey mixture into the dry ingredients. Add the orange zest, candied orange peel, and toasted almonds.
- Mix with a wooden spoon, then knead by hand in the bowl for 2 to 3 minutes until you have a firm, slightly sticky dough that holds together.
- Wrap the dough in plastic and rest at room temperature for 30 minutes. This relaxes the gluten so it rolls without snapping back.
- Heat the oven to 180 C / 350 F and line a 33 x 46 cm / 13 x 18-inch sheet pan with parchment.
- Roll the dough on a lightly floured surface to 1.5 cm thickness. Cut into diamonds about 5 cm across using a sharp knife or pastry cutter, re-rolling scraps once.
- Arrange the diamonds on the sheet pan with 2 cm between them and bake for 16 to 18 minutes, until the tops look matte and dry and the edges feel firm to the touch.
- Cool the cookies on the pan for 5 minutes, then move them to a wire rack to cool completely before glazing.
- Melt the dark chocolate with the oil in a heatproof bowl set over a small pan of barely simmering water, stirring until smooth.
- Dip the top half of each cooled cookie into the glaze, letting the excess drip off, then set them glaze-side up on parchment. Let the glaze set at room temperature for about 30 minutes before stacking.
Notes
- Warm the honey gently, boiling it changes the dough's texture.
- Rest the dough a full 30 minutes before rolling so it won't crack.
- Bake until the tops look matte, not shiny, that's the doneness cue.
- Dip cookies only once fully cooled or the glaze streaks.
Tips for Success
- Roll the dough to 1.5 cm, not thinner, or the cookies dry out before the centers set.
- Warm the honey mixture gently. Boiling it changes how the dough hydrates and the cookies come out gummy.
- Toast the almonds before chopping. Raw almonds turn the crumb soft instead of giving it crunch.
- Dip cookies only after they’re fully cool, or residual heat thins the glaze and leaves it patchy.
- Store the tin with parchment between layers so the glaze doesn’t stick to the lid.
Variations
- Swap candied orange peel for chopped dried figs and a splash of dark rum for a deeper, boozier version.
- Use hazelnuts instead of almonds and add 1 tbsp instant espresso powder to the dry mix for a coffee-forward crumb.
- Skip the chocolate glaze and dust the warm cookies with powdered sugar for a lighter, pasticceria-style finish.
Storage and Reheating
Mostaccioli napoletani keep well because honey acts as a natural preservative. Store them in an airtight tin at room temperature for 2 to 3 weeks, layered between sheets of parchment so the glaze doesn’t smudge.
Freeze the unglazed cookies for up to 2 months in a freezer bag with the air pressed out. Thaw at room temperature for an hour, then melt a fresh batch of glaze and dip, since frozen glaze tends to bloom and turn dull.
Serving Suggestions
Mostaccioli napoletani are built for the coffee break, not a dessert plate. Serve them alongside a short espresso or, for the holidays, a small glass of moscato or vin santo.
Pile them on a platter with other Neapolitan Christmas sweets like susamielli or roccocò so guests can compare the spice mixes side by side.
FAQ
Why did my mostaccioli napoletani come out dry and crumbly instead of dense?
Dry, crumbly mostaccioli usually means the dough got rolled thinner than 1.5 cm or stayed in the oven past 18 minutes. Roll to that thickness and pull the tray once the tops look matte and dry, not once they’ve started to darken. A few extra minutes turns this dense cookie into something closer to a rusk.
Can I use baking powder instead of ammonium bicarbonate in mostaccioli napoletani?
Yes, baking powder works fine in place of ammonium bicarbonate. The traditional leavener gives a slightly drier, snappier crumb, but 8 g of baking powder produces a cookie that’s still dense and holds its diamond shape after baking. Most home bakers outside Naples use baking powder anyway.
How long do mostaccioli napoletani keep in a cookie tin?
Mostaccioli napoletani keep for 2 to 3 weeks in an airtight tin at room temperature, since the honey in the dough acts as a natural preservative. Layer them with parchment so the chocolate glaze doesn’t stick to the lid. For longer storage, freeze the unglazed cookies for up to 2 months.
What goes well with mostaccioli napoletani besides coffee?
Espresso is the classic match, but a small glass of moscato or vin santo works well for a holiday table. Mostaccioli also sit naturally on a mixed cookie platter next to susamielli or roccocò, since all three share the same warm spice base without competing for attention.
Are mostaccioli napoletani dairy free?
Not as written, since the milk and most dark chocolate bars contain dairy. Swap in a plant-based milk and check the label on your chocolate, since many 70% bars are made with just cocoa mass, sugar, and cocoa butter and happen to be dairy free already. Almonds and candied peel are dairy free either way.
What’s the difference between mostaccioli napoletani and susamielli?
Mostaccioli napoletani are diamond-shaped and coated in dark chocolate glaze, while susamielli are S-shaped, left unglazed, and topped with pine nuts and colored sprinkles. Both use the same honey-and-spice base that shows up across Neapolitan Christmas baking, but the shape and finish set them apart on a dessert tray.
