Process of continuously forming individual product pieces having filler therein and having perforations of substantial size in the top layer thereof. A first continuous flat dough sheet is formed and a natural or artificial filler is periodically deposited on the first continuous flat dough sheet, each of the deposited fillers forming a mound. A perforated second continuous flat dough sheet is placed on top of the first continuous flat dough sheet and deposits of filler thereon, thereby forming a continuous composite comprising the filler deposits enclosed between the perforated, second continuous dough sheet and the first continuous flat dough sheet. The continuous composite is divided into individual pieces, each individual piece having at least one deposit of filler enclosed between a segment of the perforated, second dough sheet and a segment of the first flat dough sheet. The individual pieces are baked and packaged.
