@suzukir122 oh only 8 minutes I should think, you don't want them too over done, because the chocolate inside will be BOILING hot and the dough will be impossible to bite into without creating a whole new meaning of broken teeth. You want to make the whole with an apple corer but keep the bit that you core out (the plug), then fill in the nutella, or some other chocolate spread, then put the plug back in the whole with the chocolate in it, then put it in the oven, then take it out after 8 minutes, (i would) leave it to cool down for maybe 2 or 3 minutes. Then, you eat it!
