Preheat the oven to 325°F. Grease a 10×15-inch glass baking pan. Set aside.
In a large glass or metal bowl, add chopped chocolate.
Pour the boiling water over the chocolate. Whisk until the chocolate has melted and is fully combined into the water.
Add the butter, milk, sugar, eggs, and vanilla. Whisk until well-combined.
Add the flour, cocoa powder, baking powder, baking soda, and salt. Stir in just until smooth, but don’t overmix.
Pour the batter into the prepared baking dish.
Bake for 25-35 minutes, or until a wooden toothpick inserted in the center comes out clean.
Allow the cake to cool while you make the topping.
Add the egg yolks, milk, sugar, and molasses to a large saucepan. Whisk until combined. Add butter to the saucepan and cook over low heat.
Cook for 5-10 minutes, whisking regularly, until the mixture has thickened.
Remove from heat and stir in the vanilla extract. Add coconut and pecans, and stir until everything is well combined.
Dollop the topping evenly over the cake and then spread it with a spatula. Cool to room temperature before serving.
Notes
NOTE: If using a metal pan, preheat the oven to 350°F instead.
Tips for the Best German Chocolate Sheet Cake!
I’ve made this cake countless times over the last 30 years, and here are a few of my favorite tips for the perfect German Chocolate Cake experience!
Don’t overbake – Start checking at 25 minutes! A toothpick should come out with just a few moist crumbs, not completely clean. Overbaking dries out the cake and the custard topping won’t be able to compensate for that.
Let the cake cool before topping – Adding the hot custard to a hot cake works fine, but letting the cake cool for at least 15 minutes first gives you a slightly firmer base that holds the topping beautifully.
Toast your pecans – This is optional but highly recommended if you want a deeper flavor in your topping! A quick 5 minutes in a dry skillet over medium heat brings out a much deeper, nuttier flavor in the pecans that takes the topping to the next level.
Glass pan vs metal pan – A glass pan bakes more evenly and slowly, which is why we recommend 325°F for glass. If you use a metal pan, increase the temperature to 350°F. Either works great, just don’t swap the temperatures!
This cake gets better the next day – The custard topping soaks slightly into the top of the cake overnight and the flavors deepen significantly. If you can make it the day before your event, do it!
