Ingredients
Method
Make the dough
- Combine the warm milk and instant dry yeast in a small bowl. Stir briefly and leave for 5 minutes until slightly foamy.
- Put the flour, sugar, salt, and orange zest in a large mixing bowl or the bowl of a stand mixer. Make a well in the center.
- Add the yeast-milk mixture, eggs, honey, and vanilla extract to the well. Mix until a shaggy dough forms.
- Knead by hand on a lightly floured surface, or on medium speed with the dough hook, for 8 minutes until the dough is smooth and elastic.
- Add the butter in three additions, kneading each piece in fully before adding the next. This takes about 6 to 8 more minutes. The dough will look greasy at first, then smooth out. It should pass the windowpane test - stretch a small piece thin without it tearing.
- Form the dough into a ball, place in a lightly oiled bowl, cover with plastic wrap, and leave to rise at room temperature for 90 minutes, or until doubled in size.
Shape and second rise
- Turn the dough onto an unfloured surface. Divide into 8 equal pieces, about 80 g each.
- Shape each piece into an oval bun by rolling it gently and tucking the ends under to build surface tension. Place on a baking tray lined with parchment paper, spaced 4 cm apart.
- Cover loosely with plastic wrap and leave to rise for 60 minutes until noticeably puffed and soft to a light touch.
Bake and glaze
- Heat the oven to 180 C / 355 F, conventional (not fan) if possible.
- Bake for 18 to 20 minutes until the buns are golden on top and sound hollow when tapped on the base.
- While the buns are still hot from the oven, stir together the honey and warm water, then brush generously over the tops. The glaze will sink in slightly and give a shiny finish.
- Transfer to a wire rack and cool completely before filling, at least 45 minutes.
Whip the cream and fill
- Put the heavy cream, powdered sugar, and vanilla in a cold bowl. Whip with electric beaters on medium-high speed until the cream holds stiff peaks and does not move when you tilt the bowl.
- Score each cooled maritozzo lengthways along the top with a serrated knife, cutting about two-thirds of the way through. Open gently.
- Spoon or pipe the whipped cream generously into each bun, filling the cavity and letting it overflow both sides. Use a palette knife or the back of a spoon to smooth it level with the cut edges.
- Dust lightly with powdered sugar and serve immediately, or refrigerate for up to 3 hours before serving.
Notes
For the lightest crumb, use Manitoba flour and do not skip the windowpane test - under-kneaded dough produces dense buns that can't support the cream filling.
