Graham Cracker Crust

  • 1 ½ cups crumbed graham crackers
  • 4 tablespoons butter melted

White Cake Batter

  • 17 ouces white cake mix store-bought
  • 1 stick butter (½ cup) room temperature
  • 1 cup 2% milk
  • 3 large eggs
  • ½ cup chopped walnuts toasted
  • ½ cup white chocolate chips

Brownie Cake Batter

  • 15.5 ounce brownie mix store-bought
  • 1/3 cup olive oil
  • 3 tablespoons water
  • 1 large egg


Graham Cracker Crust

  • Preheat oven to 350º F. Cover bottom of a 12-inch skillet with parchment paper. In a medium bowl, combine graham cracker crumbs and butter until moist (I used a food processor to make crumbs). Evenly pat into bottom of skillet and bake 7 minutes; remove and let cool.

White Cake Batter

  • Beat together cake mix and butter on medium until combined. Add milk and eggs, beat on medium speed for 1 minute then medium-high for 2 minutes. Fold in toasted walnuts and white chocolate chips. Pour over crust, about half-way full; depending on depth of skillet you make not need all batter.

Brownie Cake Batter

  • In a large clean bowl, combine brownie mix, oil, water and egg; stirring with a fork or whisk for 2–3 minutes. Spoon large scoops over white cake batter to about 2/3 full, then use a butter knife to create desired swirl pattern, being careful to not over mix. If you have leftover batters bake in a separate dish.
  • Bake skillet at 350º for 25–30 minutes, or until top is set and white cake is just light golden color. Check center with a toothpick, you'll want it to come out moist with brownie batter to get fudge-like effect.


Depending on what brand you use for white cake and brownie mix, ingredients may change. Follow package direction for amounts and baking times.
