  • teaspoon Baking Soda
  • 1 tsp Baking Powder
  • ¼ tsp Salt
  • 2 Eggs (large)(room temperature)
  • 1 cup Vegetable Oil (118 ml) (or two sticks of unsalted butter)
  • 1 cup Buttermilk (237 ml) (room temperature)(substitute: whole milk and add 1 tablespoon lemon juice)
  • 1 cup Hot Water (237 ml) (very warm, not boiling)

Poke Holes in Cake - after baking:

  • 1 (14) ounce can Sweetened Condensed Milk

Chocolate Ganache Topping:

  • 1 (4) ounce bar German Chocolate
  • 4 ounces Heavy Cream

Pecan Coconut Topping:

  • 1 cup Evaporated Milk
  • 1 cup Sugar
  • 3 Egg Yolks (lightly beaten)
  • ½ cup Unsalted Butter
  • 1 teaspoon Vanilla Extract
  • 1⅓ cups Sweetened Shredded Coconut
  • 1 cup Pecans (chopped)

Instructions

  • Prepare and Bake the Cake: Preheat your oven to 350°F. Grease and flour a sheet pan. Optional: Line with parchment paper to be able to take the cake out of the pan.
  • Mix Dry Ingredients: In a large bowl, sift together 2 cups flour, 1½ cups sugar, ½ cup unsweetened cocoa powder, 1½ teaspoons baking soda, 1 teaspoon baking powder, and ¼ teaspoon salt.
  • Combine Wet Ingredients: In another bowl, whisk 2 room-temperature eggs, 1 cup vegetable oil (or melted butter), 1 cup room-temperature buttermilk, and 1 cup hot water (very warm, not boiling).
  • Combine Batter: Gradually mix the wet ingredients into the dry ingredients until smooth. Pour the batter into the prepared pan and spread evenly.
  • Bake: Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
  • Poke and Add Sweetened Condensed Milk: Remove the cake from the oven and, while still warm, use the handle on a wooden spoon to poke holes all over the cake. Open a 14-ounce can of sweetened condensed milk and slowly pour it evenly over the cake, letting it seep into the holes.
  • Prepare the Chocolate Ganache Topping: Chop a 4-ounce bar of German Chocolate and heavy cream into a small saucepan. Heat until just melted then pour over the chocolate cake. Spread evenly pushing the chocolate into the poked holes.
  • Make the Pecan Coconut Topping: Combine Ingredients: In a saucepan, combine 1 cup evaporated milk, 1 cup sugar, and 3 lightly beaten egg yolks. Add ½ cup unsalted butter and 1 teaspoon vanilla extract. Heat the mixture over medium-low heat, stirring constantly until it thickens slightly (about 5-7 minutes). Remove from heat. Stir in 1⅓ cups sweetened shredded coconut and 1 cup chopped pecans. Spread the warm pecan coconut mixture evenly over the ganache layer on the cake.
  • Finish and Serve: Allow the entire cake to cool to room temperature so all layers set. Once cooled, slice the cake into squares and serve this decadent treat!
  • Enjoy your Irresistible German Chocolate Sheet Cake—a perfect blend of rich chocolate, creamy ganache, and a crunchy, sweet pecan coconut topping!
