🍴 Ingredients
- The Chocolate Base:
- 4 oz German’s Sweet Chocolate bar, chopped
- ½ cup Water
- 1 cup (2 sticks) Unsalted butter, softened
- 2 cups Granulated sugar
- 4 Large eggs (separated)
- 2 ½ cups All-purpose flour
- 1 tsp Baking soda & ½ tsp Salt
- 1 cup Buttermilk
- The Iconic Frosting:
- 1 cup Evaporated milk
- 1 cup Granulated sugar
- 3 Large egg yolks
- ½ cup Unsalted butter
- 1 tsp Vanilla extract
- 1 ⅓ cups Sweetened shredded coconut
- 1 cup Chopped pecans
👩🍳 Instructions
1. The Chocolate Melt
- Preheat your oven to 175°C (350°F). Grease a 12×17 inch jelly roll pan (sheet pan).
- Melt the German’s chocolate in the ½ cup water over low heat. Let it cool to room temperature.
2. The Batter Build
- Cream the butter and sugar until fluffy. Beat in the egg yolks one at a time. Stir in the melted chocolate and vanilla.
- Alternately add the flour (mixed with soda and salt) and the buttermilk, beginning and ending with flour.
- The “Lifting” Tip: In a separate clean bowl, beat the 4 egg whites until stiff peaks form. Gently fold them into the batter. This is what gives German Chocolate cake its signature “velvet” crumb.
3. The Fast Bake
- Pour the batter into the sheet pan. Spread it thin.
- Bake for 20–25 minutes. Because it’s a sheet cake, it cooks much faster than a layer cake. Let it cool in the pan.
4. The Custard Frosting
- In a saucepan, combine the evaporated milk, sugar, egg yolks, and butter.
- Cook over medium heat, stirring constantly, until the mixture thickens (about 10–12 minutes).
- Remove from heat; stir in the vanilla, coconut, and pecans.
5. The Warm Spread
- While the frosting is still warm (but not hot), spread it generously over the cooled cake. The warmth helps it “grip” the surface of the cake.
The “Sheet” Hack: Sheet cakes are notorious for being hard to transport. If you need to take this to a party, let the frosting set for 1 hour, then drizzle melted semi-sweet chocolate in a cross-hatch pattern over the top. It “locks” the coconut in place and adds a bitter-sweet snap to the mild cake.
