Cake Ingredients

White Chocolate Cream Cheese Frosting


How to prepare the Pumpkin Cake

  • Preheat oven to 350 degrees F
  • Prepare an 18" x 13" baking sheet. Spray with cooking spray and dust with sugar
  • In a large mixing bowl combine the sugars, pumpkin puree, beaten eggs, oil, and vanilla. Whisk the mixture until totally combined and the mixture is smooth.
    Instead of a whisk you can also use a mixer and beat at medium speed.
  •  Mix all the dry ingredients – flour, baking powder, baking soda, salt, ginger, cinnamon, cloves, and nutmeg.  Using a wire whisk or a fork makes this easy to mix up.
  • Combine the dry ingredients into the wet ingredients and mix until the flour is completely combined, using a whisk or a mixer.
  • Spread batter into a greased and sugared pan.
  • Bake for 20 minutes then transfer the cake to a wire rack to cool.

How to prepare the White Chocolate Cream Cheese Frosting

  • Melt the white chocolate in the microwave. Do this by breaking the white chocolate bar into smaller pieces and put into a microwave-safe bowl and then microwave for 20 seconds. Remove the bowl and stir the chocolate and microwave again for 20 seconds and stir.
    Do this one more time. At this point, the chocolate should be melting and the bowl should be warm which will help melt the chocolate.
    Keep stirring until the chocolate is melted.  You do not want to put the bowl in the microwave too much as it will cause the white chocolate to seize up. But if needed go ahead and put the bowl back in the microwave for maybe 12-second intervals to get everything melted.
  • In a large mixing bowl beat the softened cream cheese and softened butter with a mixer until smooth.
  • Add the melted white chocolate and beat to combine.
  • Add the powdered sugar and beat on low speed until the icing is smooth and creamy.
  • Spread frosting on the cooled cake.

The Crumbled Topping

  • On a large cutting board place the pecans, candied ginger and dried cranberries and chop all together to get small pieces. Sprinkle this mixture on the frosted cake.
  • Since this cake has a cream cheese frosting, make sure to refrigerate any leftovers. You can let this cake sit out at room temperature for up to 8 hours, but then stick it in the fridge.


The topping is optional for this cake.  Feel free to leave it off or add your favorite topping.
Use good white chocolate such as Ghiradelli, Lindt or Valrhona. 
This cake freezes well.  Place the cut squares in a freezer container in a single layer and freeze.  To serve remove from the freezer and let thaw for two hours.
