Yes, you can! Cut your steamed and cooled Chinese New Year cake into large sections that you and your family would eat at one sitting. Freeze in sealed plastic container or sealable baggie. When you are ready to enjoy your Chinese New Year Cakes take out a section and microwave for 10-20 seconds at a time until just until slightly pliable. Slice and dip and egg, fry and enjoy! So now you can make nian gao in advance and eat it along the entire length of Chinese New Year without worrying about having to finish the cake in 3-4 days. You CAN store in freezer, then like x-mas cookies, just take out a serving just before using.
