German Chocolate Sheet Cake Recipe

A classic German Chocolate Cake made in a sheet pan for easy serving and a moist, delicious result.

Ingredients:

  • For the Cake:
    • 1 cup (2 sticks) unsalted butter, softened
    • 2 cups granulated sugar
    • 4 large eggs
    • 1 teaspoon vanilla extract
    • 4 ounces German sweet chocolate, melted and cooled
    • 2 cups all-purpose flour
    • 1 teaspoon baking soda
    • 1 teaspoon ground cinnamon
    • 1/2 teaspoon salt
    • 1 cup buttermilk
  • For the Coconut-Pecan Frosting:
    • 1 cup (2 sticks) unsalted butter
    • 1 1/2 cups granulated sugar
    • 1 (12 ounce) can evaporated milk  
    • 4 large egg yolks
    • 1 teaspoon vanilla extract
    • 1 1/2 cups shredded coconut
    • 1 1/2 cups chopped pecans

Instructions:

  1. Prepare the Cake Batter:
    • Preheat oven to 350°F (175°C). Grease and flour a 13×9 inch baking pan.
    • In a large bowl, cream together the softened butter and sugar until light and fluffy.
    • Beat in the eggs one at a time, then stir in the vanilla extract and melted German chocolate.  
    • In a separate bowl, whisk together the flour, baking soda, cinnamon, and salt.
    • Add the dry ingredients to the wet ingredients alternately with the buttermilk, beginning and ending with the dry ingredients. Mix until just combined.  
  2. Bake the Cake:
    • Pour the batter into the prepared baking pan.
    • Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
    • Let the cake cool completely in the pan.  
  3. Prepare the Coconut-Pecan Frosting:
    • In a medium saucepan, melt the butter over medium heat.
    • Stir in the sugar, evaporated milk, and egg yolks.
    • Cook over medium heat, stirring constantly, until the mixture thickens and coats the back of a spoon (about 10-12 minutes).
    • Remove from heat and stir in the vanilla extract, coconut, and pecans.
    • Let the frosting cool slightly, until it thickens enough to spread.
  4. Frost the Cake:
    • Once the cake has cooled completely, spread the coconut-pecan frosting evenly over the top.
    • let the frosting set for a short time before cutting and serving.

Tips and Notes:

  • Ensure all ingredients are at room temperature for best results.
  • Melt the German chocolate slowly and carefully to prevent it from seizing.
  • Do not overmix the cake batter, as this can result in a tough cake.
  • Keep a close eye on the frosting as it cooks, as it can burn easily.
  • For a richer flavor, toast the pecans before adding them to the frosting.
  • If you want a less sweet frosting, you can reduce the amount of sugar slightly.
  • This cake is best served at room temperature.
  • Store any leftover cake in an airtight container in the refrigerator.
