Cut the butter into small pieces and add to mixture. Add the beaten egg. (Note: the butter should be at room temperature. It should NOT be melted).

Press the crust into the bottom of an 8x8 inch pan. Use your hands to press the crust down firmly into the pan. (Note: the crust will appear very crumbly, this is ok! It solidifies when cooked).
