1-First step: Preheat your oven to 350°F and prepare two 9-inch round cake pans by greasing them with a bit of the melted unsalted butter and lining the bottoms with parchment paper. This ensures your Ding Dong Cake layers release easily and maintain their shape, adapting well if you’re using gluten-free substitutes.

2-Second step: Measure out all the dry ingredients for the cake batter, including the 1 3/4 cups all-purpose flour, 1 cup brown sugar, 1 cup granulated sugar, 3/4 cup natural cocoa powder, 1 1/2 teaspoons baking soda, and 3/4 teaspoon salt. Mix them in a large bowl to combine evenly, which helps in creating a uniform texture for your Ding Dong Cake.

3-Third step: In a separate bowl, whisk together the wet ingredients: 1/2 cup melted unsalted butter, 1/2 cup neutral cooking oil, 2 large eggs plus 1 egg yolk, 2 teaspoons vanilla extract, 1 cup buttermilk, and 1/2 cup hot coffee. For dietary adaptations, use vegan alternatives here if needed, and stir until smooth to incorporate air for a lighter cake.

4-Fourth step: Gradually add the wet mixture to the dry ingredients, stirring gently until just combined to avoid overmixing, which can make your Ding Dong Cake dense. Pour the batter evenly into the prepared pans and smooth the tops with a spatula for even baking.

5-Fifth step: Bake the cakes in the preheated oven for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Let them cool in the pans for 10 minutes, then transfer to a wire rack to cool completely, which is crucial for assembling your homemade Ding Dong Cake without it crumbling.

6-Sixth step: While the cakes cool, make the filling base by whisking 1 cup granulated sugar, 5 tablespoons all-purpose flour, and 1/4 teaspoon salt in a saucepan over medium heat. Slowly add 1 cup whole milk, stirring constantly until it thickens into a pudding-like consistency, about 5-7 minutes, and let it cool for low-calorie options.

7-Seventh step: In a mixing bowl, beat 1 cup softened unsalted butter with 1 teaspoon clear vanilla extract until fluffy, then fold in the prepared filling base. This creates the creamy center that defines a great Ding Dong Cake, and you can use vegan butter if adapting for dietary needs.

8-Eighth step: Once the cakes are fully cooled, level the tops if needed, then spread the filling evenly on one layer and top with the second layer, pressing gently. For the ganache, heat 1 cup heavy whipping cream until just simmering, pour over 8 ounces semi-sweet chocolate, and stir until smooth. Let it cool slightly before pouring over the cake.

9-Ninth step: Chill the assembled Ding Dong Cake in the refrigerator for at least 30 minutes to set the filling and ganache, making it easier to slice and serve. This final touch ensures your Ding Dong Cake looks and tastes professional, with options to adjust for different preferences like using low-sugar chocolate.
