Ingredients (Serves 20–24)
For the Cake
- 2 cups all-purpose flour
- 2 cups granulated sugar
- ½ tsp salt
- 1 tsp baking soda
- 1 cup unsalted butter
- ¼ cup unsweetened cocoa powder
- 1 cup water
- ½ cup buttermilk
- 2 large eggs
- 1 tsp vanilla extract
For the Topping
- ½ cup unsalted butter
- ¼ cup unsweetened cocoa powder
- 6 tbsp whole milk
- 3½ cups powdered sugar
- 1 tsp vanilla extract
- 1 cup chopped pecans
- 1 cup caramel sauce (store-bought or homemade)
- ½ cup semi-sweet chocolate chips
Step-by-Step Instructions
Step 1: Prepare the Cake Batter
Preheat your oven to 350°F (175°C). Grease an 18×13-inch sheet pan and set aside. In a large mixing bowl, combine flour, sugar, salt, and baking soda. In a medium saucepan, melt butter over medium heat. Add cocoa powder and whisk until smooth, then stir in water and bring to a boil. Remove from heat. Pour the hot cocoa mixture into the flour mixture and stir until combined. Add buttermilk, eggs, and vanilla extract, whisking until smooth.
Step 2: Bake the Cake
Pour the batter into the prepared sheet pan, spreading evenly with a spatula. Bake for 18–20 minutes, or until a toothpick inserted into the center comes out clean. Place the cake on a cooling rack and allow it to cool in the pan.
Step 3: Prepare the Chocolate Topping
While the cake is cooling, melt butter in a medium saucepan over medium heat. Add cocoa powder and whisk until smooth. Stir in milk and bring to a simmer. Remove from heat and gradually whisk in powdered sugar until smooth. Stir in vanilla extract.
Step 4: Frost the Cake
Pour the warm chocolate topping over the cooled cake, spreading it evenly to the edges with a spatula.
Step 5: Add the Turtle Toppings
Drizzle caramel sauce evenly over the chocolate layer. Sprinkle chopped pecans across the top, then scatter the chocolate chips so they slightly melt into the warm frosting.
Step 6: Serve
Let the cake set for 15–20 minutes before slicing into squares. Serve as is or with a scoop of vanilla ice cream for extra indulgence.
Tips & Variations
- Homemade caramel – If you have time, make your own caramel sauce for an extra touch of richness
- Extra fudgy – Add a handful of mini chocolate chips to the batter before baking
- Nut-free option – Omit pecans or replace with toffee bits for crunch without nuts
- Storage – Store covered at room temperature for up to 3 days or refrigerate for up to 5 days
- Make ahead – Bake the cake a day early, then frost and top it before serving
Serving Suggestions
This cake is perfect for large events, but it’s equally at home as a weeknight treat for the family. Pair it with fresh coffee, milk, or even a glass of dessert wine for an after-dinner indulgence. For a true “turtle sundae” effect, serve each slice with a drizzle of extra caramel and a sprinkle of sea salt.
Nutritional Benefits
While this is certainly a dessert indulgence, making it at home allows you to choose quality ingredients. Using real butter, fresh pecans, and good cocoa powder makes all the difference in both flavor and texture.
FAQ
Can I make this in a 9×13 pan? Yes, but it will be thicker and will require a longer bake time (about 28–32 minutes).
Can I freeze it? Yes, freeze unfrosted cake for up to 2 months. Thaw, then add toppings before serving.
Do I have to use buttermilk? Buttermilk gives the cake a tender crumb, but you can make a substitute by mixing ½ cup milk with ½ tbsp vinegar or lemon juice.
What’s the best way to cut a sheet cake? Use a long serrated knife and wipe it clean between cuts for neat slices.
Can I use different nuts? Absolutely—walnuts or almonds work well too.
