Equipment

  • 2 medium sauce pans
  • 2 wooden spoons
  • 1 whisk if desired
  • measuring cups
  • measuring spoons
  • 1 spatula
  • 1 11x17" jelly roll pan

Ingredients
  

CAKE:

  • 2 cups UNBLEACHED all-purpose flour (bleached flour toughens baked goods)
  • 2 cups granulated sugar
  • 1 cup unsalted butter (2 sticks)
  • 1 cup half-and-half or water
  • 4 oz. Ghirardelli white chocolate baking bar
  • 1/2 cup buttermilk (I soured a half cup of milk with 1 tbsp. white vinegar for 5 minutes)
  • 1 tsp. baking soda
  • 2 large eggs beaten
  • 1 tsp. vanilla extract

ICING:

  • 1 oz. Ghirardelli's white chocolate baking bar (2 squares)
  • 1/2 cup half-and-half
  • 1/2 cup unsalted butter (1 stick)
  • 3 cups powdered sugar
  • 1 cup walnuts chopped, or pecans (measure after chopping)
  • 1 1/2 tsp. vanilla extract

Instructions
 

CAKE:

  • Melt butter in sauce pan over low to medium heat.
  • Combine flour and granulated sugar and add to melted butter.
  • Add half-and-half and white chocolate.
  • Stir in thoroughly.
  • Let mixture come to a boil in saucepan over medium heat.
  • Remove from heat.
  • Let cool 15 minutes.
  • Dissolve baking soda in buttermilk.
  • The mixture will expand and foam.
  • Add to white chocolate mixture with eggs and vanilla.
  • Mix all together and pour into greased 11x17” jelly roll pan.
  • Bake at 400° for 20 minutes, or until a toothpick inserted in center comes out clean.
  • Mine took 30 minutes.
  • Allow cake to cool completely before adding icing.

ICING:

  • Bring white chocolate, half-and-half and butter to a boil in saucepan at low to medium heat.
  • Remove from heat.
  • Add powdered sugar, nuts and vanilla and combine well.
  • Spread icing over cooled cake.
  • Be sure to spread the nuts evenly over the cake.

Notes

NOTE: Be careful not to use too high of a heat when cooking white chocolate over top of the stove. It will burn or scorch easily.
 
NOTE: Put the buttermilk or soured milk in a 2 cup container. The mixture expands quite a bit after stirring together. Otherwise, it will overflow the one cup measuring cup.
 
NOTE: I refrigerated the cake to make it easier to cut into serving pieces.
 
NOTE: You can thicken the icing up by adding additional powdered sugar. However, you may have to make 1 1/2 batches of the recipe to get it to spread over the entire cake's surface.
