Before Making the Batters:

  • Heat the oven to 350.
  • Spray the Cross-Cake Pan with baking spray or grease and flour it as you see fit.

Prepare each batter in a separate bowl:

    Chocolate Cake Batter:

    • Sift the flour, cocoa powder, baking soda and baking powder into the bowl of an electric mixer using a sifter or a wire-mesh strainer.
    • Add salt and sugar to the bowl, and with the mixer set to low speed, beat for 30 seconds or so until combined.
    • In a separate bowl, whisk eggs, buttermilk, oil, and vanilla.
    • With the mixer set to low, add the wet mixture to the dry mixture and blend until just combined.
    • Beat in the coffee until fully incorporated.

    White Cake Batter:

    • In a medium bowl, stir milk, egg whites, and vanilla with a fork until blended.
    • In the bowl of an electric mixer, combine the cake flour, sugar, baking powder, and salt until just incorporated.
    • Add butter and continue beating on low for about 1-2 minutes.
    • Add half of the wet mixture to the flour mixture and beat at medium speed for about a minute.
    • Add the remaining wet mixture and beat for about another minute until combined.

    After Making the Batters:

    • Pour small clumps of each batter into the cross cake pan.
    • Use a spoon, fork, skewer or coffee-stirrer stick to swirl the batter in the pan.
    • Bake the cake for 40-55 minutes or until a toothpick comes out clean. [Okay, it's a little weird "testing" a cross cake with a knife or pick!]
    • Cool completely.
    • Make Frosting.
    • Colour Frosting with gel or food colouring of your choice.
    • Invert Cake onto a large serving dish.
    • Frost Cake.
    • Decorate top of cake with chocolate covered oreos.
    • Using your hand, press smashed oreo bits onto the sides of the cake.
    • Enjoy!
