Marbled Skillet Brownie Cake (White Cake and Brownie Batter Mix)

White cake and brownie batter swirled in a skillet makes an easy Marbled Skillet Brownie Cake. Baked over a graham cracker crust, with white chocolate and toasted walnuts mixed in.

Within this recipe post you’ll learn how to make a unique dessert that’s baked in a skillet, with two distinctly different batters. Plus you’ll learn about a nice surprise that happens to the baked brownie batter.

I typically use my skillet for savory main dishes like Rustic Herbed Skillet Chicken, but this time, I’m excited to dust it off and do some baking…I’m completely kidding of course and would never let that happen to my skillet. I think of it as my most prized kitchen possession, even more so than my chef’s knife, cold brew coffee maker, or 20 x 13 baking pan; and that’s some tough competition. There’s something timeless about a skillet and hope I can pass mine down for generations.

It takes special care, and must be properly dried and greased after each use to last decades, but every dish you make in a skillet is special. This Marbled Skillet Brownie Cake recipe is no exception. The ingredients and beauty of it alone are mesmerizing, and it bakes perfectly in a skillet. White cake batter swirled with brownie batter, and white chocolate chips and toasted walnuts mixed in for added decadence. To top it off (or bottom it off?) there’s a homemade graham cracker crust that adds texture and flavor. To my surprise it all works better than you can imagine.

How to bake two different batters together

Want to take a guess what happens when they bake together? Here it goes…the white cake requires less time than the brownie batter. Bake the white cake perfectly and the brownie batter remains slightly gooey and moist, but still safe and cooked through. See that open slice with all the rich, moist goodness below the surface? That’s basically fudge inside of your white cake.

Ingredients

  

1x2x3x

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
• ⅓ cup olive oil
• 3 tablespoons water
• 1 large egg

Instructions

 

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.

Notes

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