Many Chinese cakes are steamed rather than baked. Another characteristic of many Chinese cakes is that the cupcake and muffins will have a split open top. This version is made with purple sweet potatoes that give the muffins their pretty pink color.
Put steamed purple sweet potato flesh, egg, sugar, milk and oil in blender or food processor and process so that the mixture becomes a smooth paste.
Sift cake flour, rice flour and baking powder into a mixing bowl. Pour in the wet ingredients and stir until combined.
Prepare large pot of boiling water and place steamer on top. You can also use a rice cooker steamer.
Spoon batter into cupcake liners. Place the cupcake liners in a firm mold such as ramekins so that the cupcakes hold their form while cooking. Fill cupcake liners about 3/4 full and steam on high heat for 15 minutes.
