Your FOREIGNKEY syntax is wrong. This should work:

CREATE TABLE donut
(
  donutid      INT(5) NOT NULL,
  name         VARCHAR(20),
  descriptioin VARCHAR(60),
  price        DECIMAL(8,3),
  PRIMARY KEY (donutid)
);
CREATE TABLE customer
(
  customerid INT(5)NOT NULL,
  firstname  VARCHAR(30),
  lastname   VARCHAR(30),
  addres     VARCHAR(100),
  apt        VARCHAR(20),
  city       VARCHAR(30),
  state      VARCHAR(20),
  zip        VARCHAR(8),
  homephone  VARCHAR(15),
  cellphone  VARCHAR(15),
  otherphone VARCHAR(15),
  PRIMARY KEY (customerid)
);
CREATE TABLE customer_order_donut
(
  orderid    INT(10) NOT NULL,
  customerid INT(10),
  donutid    INT(10),
  orderdate  DATETIME,
  donutqty   INT(5),
  specialhandling TEXT,
  PRIMARY KEY (orderid),
  FOREIGN KEY (customerid) REFERENCES customer(customerid),
  FOREIGN KEY (donutid) REFERENCES donut(donutid)
);
