用料  

chocolate vanilla marble cake的做法  

1. prep
   1. take out 6 tbsp butter to room temp
   2. take out 3 eggs for room temp
   3. optional: if use coffee to sub water for the chocolate portion, defrost coffee cubes if having them as ice

2. --- vanilla cake (electric mixer)
   zest orange into softened butter
   
   use electric beater (whip attachment) to beat up the zest and butter lightly
   
   add in (could sift) flour, sugar, baking powder and salt, mix by hand gently and cut in the butter in low speed, till an even, crumbly texture forms ----- around 1.5 mins
   (ps. yolk put in the chocolate cake bowl)
   
   Add the buttermilk (or kefir or milk + lemon juice), egg whites and vanilla, mixing at first on LOW to combine and then for 1 min on MEDIUM speed until the batter becomes fluffy.
   
   # this is the reversed method to do the dry ingredients first (a lot less work!)
   # the body comes from egg white in this sponge

3. ---- chocolate cake (by hand)
   Melt the butter and chocolate (unsweetened bar + sugar) together in a medium saucepan over medium-low heat
   
   take off heat, add the brown sugar, coffee, and cocoa powder (to bloom better)
   
   in a large mixing bowl, whisk the egg yolks w/ the whisk attachment by hand, then add sour cream (just use weight) and whisk
   
   add in chocolate mixture and whisk well
   
   add in the other egg and whisk well
   
   add in (could sift) the flour, baking powder and salt and whisk just until smooth.
   
   check the thickness of the mixture and add in 1/4 cup milk to adjust for the missing egg whites in the mixture
   
   # the body comes from chocolate and butter, no need to bother whipping egg too much

4. grease the 9*13 inch glass baking pan
   
   preheat oven to 325F

5. dollop vanilla and chocolate mixture into the pan
   (1/2 vanilla with 1/2 chocolate, then on top of them)
   
   run a skewer through them to create a marble pattern

6. bake to 40 - 60 mins depends on the bakeware
   (metal usually takes 40, ceramic could take 50-60)
   
   * i used 50 mins this time and the skewer came out clean right then. maybe could reduce sometime next time, although it was not dry this time anyway

7. wait till complete cool before glaze, if any
   
   cool completely before store in the fridge
   
   * taste better when served cool
