Old German Chocolate Sheet Cake

I found this recipe posted on Youtube by a very sweet lady. After I tried it, I just had to post it. This recipe came from the 1950s and the cake is very moist, rich, and delicious! It takes a little time, but it is so worth it and so much better than any mix, even better than any bakery cake that I’ve ever tasted. The texture is just perfect. I hope you all enjoy it.


  • 1 pkg baker’s german sweet chocolate (4 ounces)
  • 1/2 c water
  • 2 c all-purpose flour, sifted, then measured
  • 1 tsp baking soda
  • 1/4 tsp salt
  • 1 c butter, softened
  • 2 c sugar
  • 4 large egg yolks, room temperature (reserve whites)
  • 1 tsp vanilla extract
  • 1 c buttermilk
  • 4 large egg whites, beaten to form stiff peaks

Coconut-Pecan Filling And Frosting:

  • 1 can(s) evaporated milk 12-ounce size (not sweetened condensed)
  • 1 1/2 c sugar
  • 3/4 c melted butter (1 1/2 sticks)
  • 4 large egg yolks, slightly beaten
  • 1 1/2 tsp vanilla extract
  • 7 oz baker’s angel flake coconut
  • 1 1/2 c broken pecans


1. Preheat oven to 350 degrees. Grease and flour a 9 X 13 or a 10 X 16 baking pan. If you prefer a thinner cake, use the larger pan. You may also use three 9″ pans and frost between the layers.

2. Sift two cups flour and then measure again for accuracy. Stir in baking soda and salt and set aside. Microwave chocolate in the water until chocolate is melted, about 1 minute and 30 seconds, depending on microwave. Remove from microwave and stir well, set aside.

3. Separate eggs. Beat egg whites until stiff peaks form and set aside.

4. Using a hand mixer, beat butter and sugar just until combined. Add egg yolks one at a time, mixing after each addition.

5. Slowly add melted chocolate to butter mixture while mixing. Scrape sides of the bowl with spatula and mix well. Add vanilla and mix well.

6. Add flour mixture alternately with buttermilk, beginning and ending with flour mixture. DO NOT USE A MIXER ON THIS PART!! Stir by hand using a spatula or spoon. Once mixed, you may use your hand mixer for no more than 10-20 seconds, just to make sure batter is mixed well.

8. FOR THE FROSTING: Melt butter in a heavy saucepan. Add milk, sugar, vanilla and egg yolks and cook over medium heat for about 12 minutes, stirring constantly until thickened. Remove from heat and add coconut and pecans. Stir until combined. Pour warm frosting over cooled cake.

9. SPECIAL NOTE: If you’re making the three 9″ layers, you’ll want to let the frosting cool a bit to thicken.
