Roast the peanuts in a pan without fat, take them out and chop them roughly. Peel and clean the pineapple and cut it into small pieces. Coarsely chop the chocolate. Melt chocolate and butter in a bowl over a warm water bath. Whisk the eggs with a whisk.
Mix flour and baking powder. Put melted chocolate in a mixing bowl. Add sugar, salt, eggs and flour mixture. Mix with the whisk of the hand mixer to a smooth dough. Fold in half the pineapple and peanuts. Fold the aluminium foil several times to form a firm strip. Place the strips in the middle of the fat pan of the oven (32 x 39 cm) and press firmly. Grease half of the fat pan and dust with flour. Add the dough, smooth it down and spread the rest of the pineapple on top. Bake in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for 30-40 minutes.
