Butter Mochi Cake


This is a delectably rich, buttery, and simple-to-make rendition of the traditional Japanese dessert of red-bean mochi. Traditional Japanese mochi is made from sweet rice flour mixed with water, steamed, and formed into small patties filled with sweetened red bean paste and lightly dusted with confectioner’s sugar. This butter mochi cake is a westernized version of the traditional mochi, for it incorporates butter, milk, eggs, and vanilla and is baked.


  • ½ cup unsalted butter, melted
  • 1 ¼ cups white sugar
  • 3 eggs
  • 1 teaspoon vanilla extract
  • 3 cups rice flour
  • 1 teaspoon baking powder
  • 3 cups milk
  • 1 (18.75 ounce) can sweetened red bean paste


  • Step 1
    Preheat oven to 350 degrees F (175 degrees C). Grease a 9-inch Bundt pan or a 9×13 inch baking pan.
  • Step 2
    In a large bowl, mix together the butter, sugar, eggs, vanilla and milk. Stir in the rice flour and baking powder. Pour the batter into the prepared pan. Drop red bean paste by scant teaspoonfuls onto the top of the cake. If spoonfuls are too big, the filling will sink to the bottom.
  • Step 3
    Bake for 1 hour and 10 minutes in the preheated oven, or until cake springs back when lightly touched. If using a Bundt pan, invert the cake onto a serving plate. Cake must be completely cooled before unmolding from Bundt pan, or it will be too soft to hold its shape. Serve small slices of this very rich cake at room temperature or slightly warmed.


This cake can be baked without the sweetened red bean paste. Instead, sweet red bean sauce (which is whole red beans in a sweet syrup, is usually used in Asia over grated ice to make a dessert, and is readily available in cans) can be served in a dollop on top, or to the side, of each slice of cake.
