Form 20 g (0.7 oz) balls with the semolina dough. You will get about fifty pieces.
Slightly flatten a dough ball in your hand, trying to form a hollow in the center and place a small ball of filling.
Lift the edges of the dough to completely cover the filling, then roll it between your hands to form a smooth ball. Place it on a plate and repeat the process for all the balls. Cover them with plastic wrap so they don't dry out.
If you are using a maamoul mold like mine, flour a ball of dough and place it on a floured work surface. Flour the mold, removing the excess, and press the dough ball with the mold against the work surface. (Look at the steps in the image below). Remove excess flour with a brush (the bottom of the maamoul).
If you are using a wooden mold, press the ball of dough into it, then turn it over against the work surface, giving it a sharp tap to release the formed cake.
Unmold the maamoul directly onto a baking sheet covered with parchment paper. The mold is equipped with a plunger to facilitate unmolding the cookie.
Flour the mold each time to prevent the dough from sticking. If this happens, recover the dough and filling, then reshape them.
Preheat the oven to 180°C / 350°F once you have finished shaping the maamouls.
Bake one tray at a time for about 25 minutes, until the maamouls are lightly golden.
Slide the parchment paper with the cookies onto a wire rack and let them cool completely before dusting with powdered sugar.
