Hershey Bar Cake Ingredients
For the Cake
- German Chocolate Cake Mix – This provides the base structure and rich chocolate flavor; you can substitute it with chocolate fudge cake mix for a denser cake.
- Instant Vanilla Pudding Mix – Adds moisture and richness; a different flavor pudding can be used for a fun twist.
- Eggs – Acts as a binder; for a vegan option, use 1/4 cup of unsweetened applesauce instead.
- Canola Oil – Contributes moisture and richness; light olive oil works as a suitable substitute.
- Water – Hydrates the dry ingredients for a smooth batter; replacing half with milk adds richness.
For the Frosting
- Cream Cheese – Forms the base of the frosting, adding creaminess; Neufchâtel cheese is a lighter option.
- Powdered Sugar – Sweetens and thickens the frosting; a sugar substitute can make it lower-calorie.
- Cool Whip – Enhances the lightness of the frosting; you can use homemade whipped cream instead.
- Chopped Pecans – Provides a delightful crunch; omit for a nut-free cake.
- Hershey’s Chocolate Bars – Adds texture and a rich chocolate taste; feel free to swap with dark chocolate for a deeper flavor.
For the Ganache
- Heavy Whipping Cream – Creates a smooth finish for the ganache; coconut cream works for a dairy-free option.
- Semi-Sweet Chocolate Chips – Forms the ganache; you can choose other chocolate varieties based on your sweetness preference.

Step‑by‑Step Instructions for Hershey Bar Cake
Step 1: Preheat & Prepare
Preheat your oven to 350°F (175°C). While it heats up, prepare two 9-inch springform pans by lining the bottoms with parchment paper and spraying the sides with non-stick cooking spray. This ensures your decadent Hershey Bar Cake will slide right out without any sticking or fuss.
Step 2: Mix Batter
In a standing mixer, combine the German chocolate cake mix, instant vanilla pudding mix, eggs, canola oil, and water. Mix on medium speed for about 3-4 minutes until smooth and well-blended. The mixture should be thick and glossy, indicating it’s ready.
Step 3: Bake
Pour the batter evenly between the two prepared pans, smoothing the tops with a spatula. Bake in the preheated oven for 35-45 minutes, or until a toothpick inserted in the center comes out clean. The cakes should rise beautifully and have a soft spring when pressed gently.
Step 4: Cool Layers
Once baked, remove the cakes from the oven and allow them to cool in their pans for 10 minutes. Afterward, transfer them to a wire rack to cool completely for about 30 minutes. Ensure the cakes are completely cool before proceeding to frosting; this will prevent any melting.
Step 5: Prepare Frosting
In a large mixing bowl, beat the cream cheese until smooth. Gradually add the powdered sugar while mixing, allowing everything to blend thoroughly. Gently fold in the Cool Whip, chopped pecans, and pieces of Hershey’s chocolate bars until the mixture is light and fluffy.
Step 6: Layer Cake
Carefully slice each cooled cake in half horizontally, creating four layers. Start stacking the layers by spreading a generous amount of frosting between each tier. Continue stacking and finish by applying the remaining frosting to the top and sides of the entire cake for a beautiful finish.
Step 7: Make Ganache
In a saucepan over medium heat, warm the heavy whipping cream until just beginning to simmer. Remove from heat and whisk in the semi-sweet chocolate chips until the mixture is smooth and glossy. Allow the ganache to cool slightly before drizzling it over the frosted Hershey Bar Cake.
Step 8: Finish Decoration
For the final touch, whip together some additional butter, cocoa powder, powdered sugar, vanilla, and a touch of cream to create a chocolate frosting. Use a piping bag to pipe decorative swirls around the edges of the cake, adding elegance to your already stunning Hershey Bar Cake.

Expert Tips for Hershey Bar Cake
-
Cool Completely: Allow cakes to cool fully before frosting; this prevents the frosting from melting into a gooey mess, ensuring a lovely presentation.
-
Slicing Perfectly: Use a serrated knife to slice the cake layers evenly. This helps maintain clean, beautiful layers for stacking and frosting.
-
Check for Doneness: Avoid over-baking by checking the cakes 5 minutes before the recommended time. A toothpick should come out clean but moist for a perfect Hershey Bar Cake.
-
Chill Cake Before Ganache: Let the frosted cake chill in the fridge for about 30 minutes before adding ganache. This helps the ganache set beautifully once poured.
-
Experiment with Flavors: Don’t hesitate to try different pudding flavors or even add a splash of your favorite extract to customize your Hershey Bar Cake.
