Zebra Cake - Mocha and Red Bean Taste

This evening after my fatburner class, I went home and prepared vegetarian foods for our dinner. I knew that HK and PWei will arrive home after work at 9.30pm. So I decided to bake a zebra cake with mocha and red bean taste. This is my 1st time trying this recipe.

Ingredients:
225g butter
1 cups sugar
3 large eggs
1 tablespoon vanilla
3 1/4 cups cake flour
2 1/2 teaspoons baking powder
1/4 teaspoon salt
1 1/4 cups milk
1 teaspoon mocha powder
50g red bean paste

1. Use a mixer on medium-high speed and beat butter and sugar until fluffy and pale yellow, 5 to 10 minutes.
2. Add eggs, one at a time, beating well after each addition and scraping down sides of bowl as necessary. Add vanilla.
3. In another bowl, mixed flour, baking powder, and salt. Stir (or beat at low speed) about a third of the flour mixture into butter mixture.
4. Stir in half the milk just until blended. Stir in another third of the flour mixture, then remaining milk, followed by remaining flour.
5. Seperate the batter into two portions. Add in red bean paste into one and mocha powder into another.

6. Bake in a 200°C oven until a wooden skewer inserted in the center comes out clean, 30 to 35 minutes.
