German Chocolate Sheet Cake: The Ultimate Recipe Guide

German Chocolate Sheet Cake: Prepare to be transported to a realm of pure chocolate bliss!

Imagine sinking your teeth into a rich, chocolatey cake, topped with a luscious, creamy coconut-pecan frosting that melts in your mouth. Are you drooling yet?

Despite its name, German Chocolate Sheet Cake doesn’t actually originate from Germany. It’s an American creation, born from the use of “German’s Sweet Chocolate,” a baking chocolate developed by Samuel German in 1852. This slightly sweeter chocolate became the star ingredient, giving the cake its signature flavor. The recipe gained popularity in the 1950s and has been a beloved classic ever since.

What makes this cake so universally adored? It’s the perfect combination of textures and flavors. The moist, tender crumb of the chocolate cake contrasts beautifully with the chewy, nutty, and sweet coconut-pecan frosting. Plus, the sheet cake format makes it incredibly easy to bake and serve, perfect for potlucks, parties, or simply a delightful weeknight dessert. It’s a crowd-pleaser that never fails to impress. So, let’s get baking and create a German Chocolate Sheet Cake that will have everyone begging for seconds!

this Recipe

Ingredients:

• For the Cake:
• 2 cups granulated sugar
• 2 cups all-purpose flour
• ¾ cup unsweetened cocoa powder
• 1 ½ teaspoons baking powder
• 1 ½ teaspoons baking soda
• 1 teaspoon salt
• 1 cup buttermilk
• ½ cup vegetable oil
• 2 large eggs
• 2 teaspoons vanilla extract
• 1 cup boiling water
• For the Coconut Pecan Frosting:
• 1 cup (2 sticks) unsalted butter
• 1 cup packed light brown sugar
• ½ cup evaporated milk
• 4 large egg yolks
• 1 ½ teaspoons vanilla extract
• 1 ½ cups shredded sweetened coconut
• 1 ½ cups chopped pecans

Preparing the Cake Batter:

1. Combine Dry Ingredients: In a large bowl, whisk together the granulated sugar, flour, cocoa powder, baking powder, baking soda, and salt. Make sure everything is evenly distributed. This ensures a consistent flavor and texture throughout the cake.
2. Add Wet Ingredients (Except Boiling Water): In a separate bowl, whisk together the buttermilk, vegetable oil, eggs, and vanilla extract. Pour this wet mixture into the dry ingredients.
3. Mix Until Just Combined: Using an electric mixer (or a sturdy whisk), mix the wet and dry ingredients together until just combined. Be careful not to overmix, as this can lead to a tough cake. A few lumps are okay at this stage.
4. Add Boiling Water: Gradually pour the boiling water into the batter while mixing on low speed. The batter will be very thin – don’t worry, this is normal! The hot water helps to bloom the cocoa powder, intensifying its flavor and creating a moist cake.

Baking the Cake:

1. Prepare the Baking Sheet: Preheat your oven to 350°F (175°C). Grease and flour a 13×18 inch baking sheet (also known as a half sheet pan). Alternatively, you can line the pan with parchment paper, leaving an overhang on the sides for easy removal. This is my preferred method!
2. Pour Batter into Pan: Pour the thin cake batter evenly into the prepared baking sheet. Use a spatula to spread it out to the corners.
3. Bake the Cake: Bake for 20-25 minutes, or until a wooden skewer inserted into the center comes out clean. Keep a close eye on it, as baking times can vary depending on your oven.
4. Cool the Cake: Let the cake cool completely in the pan on a wire rack. This is crucial before frosting, as warm cake will melt the frosting. I usually wait at least an hour, or even longer if I have the time.

Making the Coconut Pecan Frosting:

1. Melt the Butter: In a medium saucepan, melt the butter over medium heat.
2. Add Brown Sugar and Evaporated Milk: Stir in the brown sugar and evaporated milk. Bring the mixture to a simmer, stirring constantly to prevent burning.
3. Cook Until Slightly Thickened: Continue to cook the mixture, stirring constantly, for about 5-7 minutes, or until it thickens slightly. It should be thick enough to coat the back of a spoon.
4. Temper the Egg Yolks: In a small bowl, whisk the egg yolks. Slowly drizzle a small amount of the hot butter mixture into the egg yolks, whisking constantly to temper them. This prevents the eggs from scrambling when added to the hot mixture.
5. Add Egg Yolks to Saucepan: Pour the tempered egg yolk mixture back into the saucepan with the remaining butter mixture.
6. Cook Until Thickened: Cook over low heat, stirring constantly, for another 2-3 minutes, or until the frosting thickens further. Be careful not to boil the frosting, as this can cause it to curdle.
7. Remove from Heat and Stir in Vanilla: Remove the saucepan from the heat and stir in the vanilla extract.
8. Add Coconut and Pecans: Stir in the shredded coconut and chopped pecans. Mix well to combine.
9. Cool Slightly: Let the frosting cool slightly for about 15-20 minutes before frosting the cake. This will make it easier to spread.

Frosting and Serving:

1. Frost the Cake: Once the cake is completely cool and the frosting has cooled slightly, spread the frosting evenly over the top of the cake.
2. Cut and Serve: Cut the cake into squares and serve. This cake is best enjoyed at room temperature.

Tips for Success:

• Use Good Quality Cocoa Powder: The quality of your cocoa powder will significantly impact the flavor of the cake. I recommend using a Dutch-processed cocoa powder for a richer, smoother flavor.
• Don’t Overbake: Overbaking the cake will result in a dry cake. Check for doneness with a wooden skewer, and remove the cake from the oven as soon as it comes out clean.
• Cool Completely Before Frosting: This is essential to prevent the frosting from melting. Be patient!
• Adjust Sweetness to Taste: If you prefer a less sweet frosting, you can reduce the amount of brown sugar slightly.
• Toast the Pecans: For an even more intense pecan flavor, toast the pecans in a dry skillet over medium heat for a few minutes before adding them to the frosting. Watch them carefully, as they can burn easily.
• Make Ahead: The cake can be baked a day ahead of time and stored at room temperature, tightly wrapped. The frosting can also be made a day ahead and stored in the refrigerator. Bring the frosting to room temperature before frosting the cake.
• Storage: Store leftover cake in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to 5 days.

Variations:

• Chocolate Chips: Add ½ cup of chocolate chips to the cake batter for an extra chocolatey treat.
• Espresso Powder: Add 1 teaspoon of espresso powder to the dry ingredients to enhance the chocolate flavor.
• Bourbon: Add 1-2 tablespoons of bourbon to the frosting for a boozy kick.
• Different Nuts: Substitute the pecans with walnuts or almonds.
• Cream Cheese Frosting: For a different frosting option, try a classic cream cheese frosting.

Troubleshooting:

• Cake is Dry: Make sure you are not overbaking the cake. Also, ensure you are using the correct amount of liquid ingredients.
• Frosting is Too Thin: Cook the frosting for a longer period of time to allow it to thicken.
• Frosting is Too Thick: Add a tablespoon or two of evaporated milk to thin the frosting.
• Cake is Sinking in the Middle: This could be due to underbaking or using too much leavening agent (baking powder or baking soda).
