How To Make German Chocolate Sheet Cake

- In a large bowl, mix together the flour, sugar, and cocoa powder.
- In a small saucepan, add the water, butter, shortening, and chocolate. Bring to a boil over medium heat. Once the mixture is smooth and fully combined, add it to the dry ingredients and whisk to combine.
- Stirring between each addition, first add the buttermilk, baking soda, salt, eggs, and then vanilla.
- Transfer batter to the prepared sheet pan and bake for 20-22 minutes. Let cool before frosting.
FROSTING

- Stir in coconut, pecan, and vanilla.
- Let frosting cool slightly and then spread over the cooled cake.
- Chill for 1-2 hours, then serve.
