Preheat oven to 350 degrees Fahrenheit. Grease a nine-inch square pan and set aside.

In a bowl, mix together oil, sugar, vanilla, and eggs until well incorporated.

Microwave half a cup of lotus butter for 20 seconds. Add to the bowl the softened lotus butter, flour, baking powder, baking soda, salt, cinnamon, cornstarch, and pudding powder. Mix until everything is combined.

Press batter into prepared pan. Bake 25 to 30 minutes.

Cut into squares. If desired, drizzle with additional (softened) lotus butter and sprinkle with crushed lotus cookies.
