Grandma’s Authentic German Chocolate Cake is a time-honored dessert rooted in warm kitchens, handwritten recipe cards, and the kind of home-baked love that only a grandmother can offer. This classic cake is cherished for its tender, moist chocolate layers and rich, caramelized coconut-pecan frosting—a sweet, nutty topping that transforms every bite into a celebration. Whether it was reserved for birthdays, Sunday dinners, or special holidays, this cake often held a place of honor at the center of the table. Passed down through generations, it’s more than just a recipe—it’s a piece of family history, a connection to the past, and a delicious way to preserve tradition. Though modern versions abound, nothing compares to the depth of flavor and homemade charm that comes from baking it just like Grandma did—using real ingredients, simple steps, and a little bit of heart in every layer.
The History of German Chocolate Cake
Despite its name, German Chocolate Cake is not a product of German origin but rather an all-American invention with a fascinating backstory. The name comes from Samuel German, an English-American chocolatier who, in 1852, developed a type of mild dark baking chocolate for the Baker’s Chocolate Company. In 1957, a recipe for “German’s Chocolate Cake” appeared in a Dallas newspaper, submitted by a Texas homemaker. This cake, which featured layers of chocolate cake with a unique coconut and pecan frosting, quickly captured the hearts of home bakers across the country. As its popularity grew, the apostrophe-s was eventually dropped, and it became known simply as “German Chocolate Cake.” Its roots may lie in a brand name, but the legacy of the recipe is now firmly embedded in American culinary culture. Over time, it evolved from a trendy treat to a beloved classic found in cookbooks, on holiday tables, and in grandmother’s treasured handwritten notes. Its combination of sweet chocolate, buttery frosting, and chewy coconut still makes it a standout dessert decades later.

- 2 cups (400 g) granulated sugar
- 1 3/4 cups (210 g) all-purpose flour
- 3/4 cup (75 g) unsweetened cocoa powder
- 1 1/2 teaspoons (6 g) baking powder
- 1 1/2 teaspoons (7.5 g) baking soda
- 1 teaspoon (5 g) salt
- 2 large eggs
- 1 cup (240 ml) buttermilk
- 1/2 cup (120 ml) vegetable or canola oil
- 2 teaspoons (10 ml) vanilla extract
- 1 cup (240 ml) boiling water
For the Coconut-Pecan Frosting:
- 1/2 cup (100 g) light brown sugar
- 1/2 cup (100 g) granulated sugar
- 1/2 cup (115 g) butter
- 3 large egg yolks
- 3/4 cup (180 ml) evaporated milk
- 1 tablespoon (15 ml) vanilla extract
- 1 cup (120 g) chopped pecans
- 1 cup (80 g) sweetened shredded coconut
For the Chocolate Buttercream (Optional):
- 1/2 cup (115 g) butter
- 2/3 cup (65 g) unsweetened cocoa powder
- 3 cups (360 g) powdered sugar
- 1/3 cup (80 ml) evaporated milk
- 1 teaspoon (5 ml) vanilla extract
Step-by-Step Recipe
Preheat the oven to 375°F (190°C). Grease two 8-inch or 9-inch round cake pans and line the bottoms with parchment or wax paper for easy removal. In a large bowl, whisk together the sugar, flour, cocoa powder, baking powder, baking soda, and salt. In a separate bowl, mix the eggs, buttermilk, oil, and vanilla until well blended. Combine the wet and dry ingredients, then carefully stir in the boiling water—the batter will be thin, which is perfectly normal. Divide the batter evenly between the prepared pans and bake for 25 to 35 minutes, adjusting based on your pan size. A toothpick inserted in the center should come out clean or with a few crumbs. Let the cakes cool in the pans for 5 minutes before turning them out onto wire racks to cool completely.
To prepare the coconut-pecan frosting, add the brown sugar, granulated sugar, butter, egg yolks, and evaporated milk to a medium saucepan. Stir to combine and bring to a gentle boil over medium heat, stirring constantly. Continue cooking and stirring until the mixture thickens, about 10 to 12 minutes. Remove from heat and stir in the vanilla, chopped pecans, and shredded coconut. Let the frosting cool completely before using.
To make the optional chocolate buttercream, melt the butter and stir in the cocoa powder until smooth. Gradually alternate adding powdered sugar and evaporated milk, beating until the frosting reaches your desired consistency. Add more milk or sugar as needed, then stir in the vanilla.
Cake Assembly
Place one cooled cake layer on a serving platter or cake stand. Spread a thin layer of chocolate buttercream over the surface, if using. Spoon half of the cooled coconut-pecan frosting on top and spread it evenly, leaving a slight border around the edge. Place the second cake layer on top and frost the entire cake with chocolate buttercream. Finish by spreading the remaining coconut-pecan frosting generously over the top of the cake. Chill briefly to set before slicing and serving.
Tips for the Perfect German Chocolate Cake
Use room-temperature ingredients to ensure smooth mixing and even baking. Be cautious not to overmix the batter, particularly when adding the boiling water. For extra flavor, toast the pecans before stirring them into the frosting. Always let the coconut frosting cool completely to avoid sliding off the cake. If baking at high altitude, add 3 tablespoons of flour to prevent the cake from sinking. Line the pans with parchment for easy removal, and cool cake layers fully before assembling. For neat slicing, chill the cake for at least 30 minutes before serving. A serrated knife will help cut through the dense layers cleanly.
Variations and Customizations
Turn this recipe into cupcakes for individual portions, adjusting the baking time to about 18–22 minutes. Swap pecans for walnuts or even almonds for a different twist. Try using dark chocolate in the cake batter or add espresso powder for deeper flavor. Make it gluten-free by substituting a 1:1 gluten-free flour blend. For a dairy-free version, use coconut milk instead of evaporated milk and a vegan butter alternative. Add a layer of chocolate ganache or mousse between cake layers for extra decadence. Want a showstopper? Decorate the cake sides with extra chopped pecans or piped chocolate buttercream rosettes.
Health Considerations and Nutritional Value
German Chocolate Cake is rich and indulgent, typically high in sugar, fat, and calories. A single slice can range from 500 to 700 calories, depending on frosting thickness and portion size. It’s best enjoyed as an occasional treat. To lighten it slightly, reduce the sugar, use low-fat or plant-based milk, and opt for unsweetened coconut. Using high-quality dark chocolate can also provide antioxidants and reduce sugar content. Those with nut allergies or lactose intolerance should use alternative ingredients like oat milk or nut-free frosting versions. If you’re watching your intake, consider serving smaller slices or making mini cakes for better portion control. Despite its richness, the cake contains beneficial elements like fiber from coconut and protein from eggs and nuts, but moderation is key.

Grandma’s Authentic German Chocolate Cake Recipe
Ingredients
For the Cake:
- 1 package 4 oz German sweet chocolate
- 1/2 cup 4 oz boiling water
- 2 sticks 226 g unsalted butter
- 1/2 teaspoon salt
- 1 teaspoon baking soda
- 1 cup 8 oz buttermilk
- 2 cups 400 g granulated sugar
- 4 egg yolks unbeaten
- 1 teaspoon vanilla extract
- 2 cups 240 g all-purpose flour
- 4 egg whites
For the Frosting:
- 1 can 12 oz evaporated milk
- 1 1/2 cups 300 g granulated sugar
- 1 1/2 sticks 170 g unsalted butter
- 4 egg yolks lightly beaten
- 1 1/2 teaspoons vanilla extract
- 1 package 7 oz sweetened shredded Baker’s coconut
- 1/2 cup 65 g chopped pecans
Instructions
- Preheat your oven to 350ºF (175ºC). Line the bottoms of two 8″ x 3″ round cake pans with parchment paper and grease the sides with butter to prevent sticking.
- Using a stand mixer fitted with the paddle attachment, cream together the butter and sugar on medium-high speed for about 3 minutes, making sure to stop and scrape down the sides and bottom of the bowl halfway through to ensure a smooth mixture without lumps.
- Add the egg yolks one at a time, mixing well after each addition. Continue mixing on medium-high speed for about 4 minutes, or until all the yolks are fully incorporated and the mixture is light and fluffy.
- In a separate bowl, combine the German sweet chocolate with the boiling water, stirring until the chocolate is completely melted and smooth. Let it cool slightly, then add the melted chocolate and vanilla extract to the creamed mixture. Mix on medium speed for 3 minutes, or until everything is well blended.
- In another bowl, sift together the flour, salt, and baking soda. With the mixer on medium-high speed, alternate adding the dry ingredients and the buttermilk to the chocolate mixture, starting and ending with the dry ingredients. Continue mixing for about 5 minutes, scraping the bowl again halfway through to ensure an even batter.
- In a clean bowl, use the whisk attachment to beat the egg whites on high speed for about 5 minutes, or until stiff peaks form. Carefully fold the beaten egg whites into the cake batter, taking care not to deflate the mixture. Fold gently until fully combined.
- Divide the batter evenly between the prepared pans and place them in the oven. Bake for approximately 45 minutes, or until a toothpick inserted into the center comes out clean.
- While the cakes are baking, begin making the frosting. In a medium saucepan, combine the evaporated milk, sugar, butter, egg yolks, and vanilla extract. Stir the mixture together and cook over medium heat for about 12 minutes, or until it thickens and becomes rich and golden.
- Remove the saucepan from heat and stir in the shredded coconut and chopped pecans. Mix well until everything is evenly combined. Set the frosting aside to cool completely before using it to assemble and frost the cake.
- Once the cakes are fully baked and cooled, layer them with the coconut-pecan frosting. Slice, serve, and enjoy every bite of this classic homemade German Chocolate Cake!
