Beat butter and sugar until fluffy. Add the eggs one by one and beat evenly. Then add the crackers and stir evenly.
Divide the batter into three portions, add cocoa powder to one portion and mix well for later use.
After the water is boiled, pour a portion of the original batter into a mold that has been covered with greased paper, and then smoothen it out and steam it for 15 minutes.
The second layer (cocoa flavor) is also to be steamed for 15 minutes.Then add in the last layer. (original flavor) and steam for another 25 to 30 minutes until the cake is fully cooked.
Turn off the flame, take it out and wait for it to cool down. You're done!
