Transform a simple box of chocolate cake mix into nostalgic bars that capture all the magic of classic Ding Dongs. These decadent treats feature layers of tender chocolate cake, fluffy marshmallow filling, and rich chocolate ganache.
Through testing, I've discovered that proper layering and chilling times create the perfect texture combination.
Essential Ingredients
- For Cake:
- Chocolate Cake Mix: Any brand
- Unsalted Butter: Room temperature
- Large Eggs: For cake mix
- Water: As directed on box
- Oil: As directed on box
- For Filling:
- Marshmallow Crème: Full jar

Detailed Instructions
- 1. Cake Base Preparation:
- Heat oven to 350°F. Line a 9x13 pan with parchment, leaving overhang for easy removal. Prepare cake mix according to package directions. Pour into prepared pan. Bake for 25 minutes or until a tester comes out clean. Cool completely on a wire rack, about 1 hour.
- 2. Ganache Creation:
- Combine chocolate chips and hot cream in a microwave-safe bowl. Microwave in 15-second intervals, whisking between each, until smooth and glossy. Refrigerate until thickened to hot fudge consistency, about 45 minutes.
- 3. Marshmallow Filling:
- Beat softened butter until light and creamy, about 3 minutes. Add powdered sugar and salt, beat until combined. Mix in marshmallow crème and vanilla until smooth and fluffy, about 2 minutes.
- 4. Assembly Process:
- Spread marshmallow filling evenly over cooled cake. Refrigerate for 30 minutes until set. Pour thickened ganache over filling, smoothing with an offset spatula.
- 5. Setting Time:
- Refrigerate until chocolate is completely set, about 1 hour. Use parchment overhang to lift from pan. Cut into 18 pieces with a sharp knife.
