A sandy texture and traditional soul defined by fine corn flour and sweet milk jam. It is the kind of bite that melts in your mouth and brings back cozy home afternoons, a tender cookie that celebrates simple craft. Pure handmade softness in every bite.

Sift the corn flour, cornstarch, baking powder, ground cinnamon, and salt into a bowl. Mix briefly so the dry ingredients are even and free of lumps.
In another bowl, work the unsalted butter with the powdered sugar for 2 minutes, until creamy and pale. Add the egg yolks
Turn what you find into an experience you can actually bring to your kitchen.

Add the dry ingredients in two additions and bring everything together gently into a compact dough. Do not overwork it: once no loose flour remains, the dough is ready.
Cover the dough and refrigerate for 15 minutes. Shape 32 small balls, flatten them just slightly, and place them on a tray lined with parchment paper, leaving a little space between them.
Bake at 170°C for 13 minutes, until the bases are just lightly golden and the tops stay pale. Let them cool for 10 minutes on the tray before moving; they break easily when hot.
Sandwich the cooled cookies with milk jam, using an even layer without overflowing. Press lightly to assemble 16 maicillos; they should feel fragile, sandy, and mellow in the center.
