There are chocolate cakes… and then there’s German Chocolate Sheet Cake — the kind of dessert that disappears before you even set down the serving knife. Deep, fudgy chocolate cake topped with that iconic coconut-pecan frosting, slightly gooey, buttery, and caramel-like in texture. It’s nostalgic, indulgent, and absolutely unforgettable.
I’m Chef James, and here at Tiramisucake.com — home of our reader-favorite Classic Tiramisu Recipe — we celebrate desserts that bring people together. This German Chocolate Sheet Cake is exactly that kind of recipe. It’s big enough to feed a crowd, easy enough for a weeknight, and special enough for birthdays, holidays, and potlucks.
Despite the name, German Chocolate Cake isn’t from Germany. It’s named after Samuel German, who developed a dark baking chocolate for Baker’s Chocolate Company in the 1850s. The sheet cake version keeps all the rich flavor but simplifies the process — no stacking layers, no complicated assembly. Just bake, frost, slice, and enjoy.
Because this cake contains eggs, butter, milk, and coconut topping, proper storage matters. According to the USDA, perishable desserts should be refrigerated when necessary and kept below 40°F for food safety. You can review official guidelines here:

The Secret to Authentic German Chocolate Flavor
The magic of this cake comes from three components:
🍫 The Chocolate Base
Traditionally made with sweet baking chocolate for a smooth, mellow cocoa flavor.
🥥 The Coconut-Pecan Frosting
Cooked custard-style with egg yolks, butter, sugar, and evaporated milk — creating that signature caramel texture.
🌰 Toasted Pecans
They add crunch and balance the sweetness.
This is not a buttercream cake. It’s about contrast: moist chocolate cake and sticky, nutty topping.
Ingredients (Serves 15–18)
For the Chocolate Cake
- 2 cups (250g) all-purpose flour
- 1 ¾ cups (350g) granulated sugar
- ¾ cup (75g) unsweetened cocoa powder
- 1 ½ tsp baking powder
- 1 ½ tsp baking soda
- 1 tsp salt
- 2 large eggs
- 1 cup (240ml) buttermilk
- ½ cup (120ml) vegetable oil
- 2 tsp vanilla extract
- 1 cup (240ml) hot coffee
Chef James Tip: Hot coffee enhances chocolate flavor without making the cake taste like coffee.
For the Coconut-Pecan Topping
- 1 cup (200g) granulated sugar
- 3 large egg yolks
- 1 cup (240ml) evaporated milk
- ½ cup (113g) unsalted butter
- 1 tsp vanilla extract
- 1 ½ cups sweetened shredded coconut
- 1 cup chopped pecans

Step-by-Step Instructions
Step 1 – Prepare the Pan
Preheat oven to 350°F (175°C).
Grease a 9×13-inch baking pan.
Step 2 – Mix the Cake Batter
In a large bowl, whisk flour, sugar, cocoa powder, baking powder, baking soda, and salt.
Add eggs, buttermilk, oil, and vanilla. Mix until smooth.
Slowly stir in hot coffee.
Chef James Extra Tip: The batter will be thin — that’s what creates a moist cake.
Step 3 – Bake
Pour into prepared pan.
Bake 30–35 minutes.
Cool completely before frosting.
Making the Signature Coconut-Pecan Topping
Step 4 – Cook the Custard Base
In a saucepan over medium heat:
Combine sugar, egg yolks, evaporated milk, and butter.
Cook, stirring constantly, until thickened (about 10–12 minutes).
Chef James Tip: Don’t rush this step — constant stirring prevents scrambling the yolks.
Step 5 – Add Coconut & Pecans
Remove from heat.
Stir in vanilla, coconut, and pecans.
Let cool until spreadable.
Step 6 – Frost the Cake
Spread evenly over cooled cake.
No need to refrigerate before serving unless desired.
