Step 1: Make the Filling Base
In a saucepan, whisk together the sugar, flour, and salt. Slowly pour in the milk while whisking until smooth. Heat over medium, stirring constantly, until the mixture thickens into a pudding-like texture. Transfer to a bowl, press plastic wrap or wax paper onto the surface, and let cool completely.
Step 2: Bake the Cakes
Preheat your oven to 350°F (175°C). Grease and line two 8″ round cake pans.
In a large bowl, whisk together the flour, both sugars, cocoa powder, baking soda, and salt. Add the melted butter and oil, and mix until smooth. Stir in the eggs, yolk, and vanilla.
Add the buttermilk and stir to combine. Finally, carefully pour in the hot coffee and stir until you get a smooth, pourable batter.
Divide the batter evenly between the pans and bake for 33–35 minutes, or until a toothpick comes out with just a few moist crumbs. Cool in the pans for 15 minutes, then turn out onto a rack to cool completely.
Step 3: Finish the Filling
Once the filling base is cooled to room temp, beat the softened butter until fluffy. Gradually add the filling base one spoonful at a time, mixing well after each addition. Stir in the vanilla and whip until smooth and airy.
Chill in the fridge for 15–20 minutes while you prep the ganache.
Step 4: Make the Ganache
Place chopped chocolate and cream in a heatproof bowl. Microwave in 25-second intervals, stirring between each, until smooth and glossy. Let it cool until it thickens to a spreadable consistency.
Step 5: Assemble
Trim the tops of the cakes if needed to level. Place one layer on a serving plate and spread all of the filling on top — don’t worry if it squishes out a bit. Add the second cake layer and press gently. Smooth the sides with any extra filling that escaped.
Chill the stacked cake for 15 minutes, then spread ganache over the top and sides. Refrigerate for at least 15 more minutes before slicing.
Frequently Asked Questions
Do I need to refrigerate Ding Dong Cake?
Yes! Because of the soft, buttery filling, the cake should be stored in the fridge. Let it sit at room temp for 10–15 minutes before serving.
Can I use a different frosting for the filling?
You can! Try a marshmallow frosting or vanilla buttercream if you prefer a sweeter filling, but ermine frosting gives it that authentic texture.
What if my filling looks curdled?
Don’t panic! Just keep whipping — it usually comes together. If it doesn’t, chill the bowl for 15–20 minutes and then try again.
Can I make this as cupcakes?
Yep! Fill cupcake liners ⅔ full and bake for about 17 minutes. Use the same filling and ganache to finish them off.
How long does Ding Dong Cake last?
It keeps well for up to 5 days in the fridge, covered. The texture actually improves after a day as the flavors settle.
Quick Tips Before You Start
. Let the filling base cool completely before whipping with butter — or it’ll split.
. Hot coffee deepens the chocolate flavor, but hot water works in a pinch.
. Clear vanilla gives that classic Ding Dong flavor, but regular extract works too.
. If your ganache thickens too much, microwave it for 5–10 seconds to soften.
