Cover the glutinous rice with about 2 inches of cold water. Soak for at least 3 hours, or preferably overnight.
Drain and rinse the soaked rice a few times. Mix in the coconut oil and sugar. Stir well until the sugar melts and the rice is evenly coated.
Arrange the toppings in the bottom of a wide heat-proof bowl after coating the bowl with more coconut oil. Begin with the walnuts in the middle, then jujubes, raisins, goji berries, and pumpkin seeds.
Spoon two-thirds of the rice into the bowl over the toppings. Gently press it down without disturbing the design. Create a small dent in the center and fill it with red bean paste, spreading it into a thin layer.
Add the remaining rice on top and smooth the surface.
Return the assembled bowl to the steamer. Steam for another 60 minutes.
While the rice is steaming, combine water, sugar, and chrysanthemum buds in a small saucepan. Bring to a boil over medium heat, then reduce to medium-low and simmer for 10 minutes.
Mix cornstarch with 1 teaspoon of water until fully dissolved. Stir the slurry into the saucepan. Continue cooking and stirring until the syrup slightly thickens. Strain into a bowl and discard the chrysanthemum buds.
When the rice is finished steaming, spoon a few tablespoons of syrup over the top. Let it rest for 10 minutes.
To serve, place a plate over the bowl and carefully flip it over in one quick motion. Remove the bowl and pour the remaining syrup on top. Serve warm.
