First, make sure you have a clean muffin pan and spray it down with cooking oil. If using English muffins, divide each one into halves and put one half in each of the muffin trays. For premade pastry dough, divide evenly into the indents, making sure the bottom is completely covered. For homemade bread dough, take a small piece of dough and form it to each indent, let rise for 20 minutes than bake at 400 degrees for 5 minutes.
