final Image image = new Image(getClass().getResource("cross_red.png").toExternalForm(),20,true,true);
MenuButton menuButton = new MenuButton("Don't touch this");
menuButton.setGraphic(new ImageView(image));
menuButton.getItems().addAll(new MenuItem("Really"),new MenuItem("Do not"));

This will generate a button, such as:

Note: if you want the button to be like a real button, you can switch from MenuButton to split MenuButton The only difference is that the control field is divided into button part and drop-down part (so you can also assign actions as titles):
