Baked Mochi Cake with Sweet Red Bean Paste

At Lunar New Year time, we eat a sticky steamed cake called neen gao (nian gao). It's supposed to bring a prosperous new year and it's also what is offered to the Kitchen God to gum up his mouth so he won't give a bad report on the family to Heaven. I also love mochi cakes filled with sweet red bean paste.  I buy them already made, 6 to a pack, or make them at home if I'm motivated.  They are not that hard to make, but it's still a pain - the mochi dough is sticky, the starch powder gets all over everything, and it's tedious making all those little round cakes.  Here's a way to get the sticky sweet gooey taste of mochi, plus the red bean flavor, with lots less work.  Try it!

Mochi Cake

Ingredients:
  • 1 pound of Sweet Mochi, or Glutinous Rice Flour* (like Mochiko brand)
  • 1 Tbsp baking powder
  • 1 cup sugar, or 2 cups brown sugar
  • 2½ cups milk
  • ¾ cup vegetable oil
  • 4 large eggs
  • 1 Can (18 oz) of sweetened adzuki red bean paste* (I used a 17.6 oz pouch)
  • 1 egg, beaten, to brush on top of cake (optional)
  • Sesame seeds* to sprinkle (optional - can be toasted before using)

You can experiment with reducing the sugar if you want.  I made this cake with 1½ cups brown sugar and it tasted great.  I have also reduced the oil to 1/2 cup with decent results.

Instructions:
  1. Preheat the oven to 375° F.
  2. Mix everything together, except for the last three ingredients.  The batter will be runnier than a typical cake batter. 
  3. Pour half of the mixture into a 9" x 13" pan, lined with parchment paper or foil.  It's about 6 2/3 cups batter total, so half is about 3 1/3 cups.
  4. Bake for 20 minutes.
  5. Take the cake out and spread all the red bean paste evenly on top, and then pour the rest of the cake mixture on top of everything.
  6. Squeeze out the red bean paste in lines across the cake.
    Spread red bean paste in an even layer.
  7. Sprinkle with sesame seeds.  Bake another 20-25 minutes, until cake is set and lightly browned at the edges.
  8. Remove and let cool on a rack.  Slice with a serrated knife. It's delicious warm, and even more delicious when cooled down to room temp.
*I get these Asian ingredients from 99 Ranch Market which is here in southern California.  Mochiko brand flour cost $3-over $4 per 16 oz box.  Flying Horse brand is only 99¢. Other food markets in Chinatowns, Japantowns, or Koreatowns would also likely carry this stuff.
