Prep & Cook Tools
Before you get started, make sure you have the following tools on hand:
- Mixing bowls: For combining your ingredients.
- Measuring cups and spoons: Precision is key in baking.

Turtle Cake (Chocolate Brownie Cake Recipe): How It’s Done

Step 1: Prepare the Oven and Baking Pan
Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan to ensure the cake comes out easily after baking.
Step 2: Mix the Cake and Brownie Batters
In a large mixing bowl, combine the German chocolate cake mix, fudge brownie mix, eggs, water, and canola oil. Mix until well combined and the batter is smooth. The combination of these two mixes will create a rich and flavorful base for your Turtle Cake.
Step 3: Bake the Base
Pour the batter into the prepared baking pan and spread it evenly. Bake in the preheated oven for about 30-35 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs. Allow the cake to cool in the pan on a wire rack.
Step 4: Make the Caramel Filling
While the cake cools, melt the baking caramels and milk together in a double boiler or microwave-safe bowl. Stir until smooth and creamy. Once melted, fold in 1 cup of the chopped pecans.
Step 5: Layer the Caramel and Cake
Once the cake has cooled slightly, pour the caramel-pecan mixture over the top of the cake, spreading it evenly. This will create a delicious gooey layer that complements the dense chocolate base.
Step 6: Prepare the Chocolate Ganache
In a small saucepan, heat the heavy whipping cream over medium heat until it begins to simmer. Remove from heat and add the semisweet chocolate morsels. Stir until the chocolate is completely melted and the mixture is smooth.
Step 7: Finish the Cake
Pour the chocolate ganache over the caramel layer, spreading it out evenly. Top with the remaining ½ cup of chopped pecans and the chopped chocolate/caramel turtle candies for added texture and flair.
Step 8: Chill and Serve
Refrigerate the cake for at least 1 hour to allow the ganache to set. Once set, slice into squares and serve. The Turtle Cake (Chocolate Brownie Cake Recipe) is best enjoyed chilled, allowing the flavors to meld beautifully.
Budget & Availability Swaps

If you’re looking to make this Turtle Cake more budget-friendly or need to substitute ingredients, consider the following options:
- Canola oil: Swap for vegetable oil or melted coconut oil.
- Heavy whipping cream: Use coconut cream for a dairy-free option.
- Pecans: Substitute with walnuts or almonds if desired.
- Chocolate morsels: Any type of chocolate chips can work in a pinch.
Pitfalls & How to Prevent Them
When making this Turtle Cake, keep these common pitfalls in mind to ensure your baking success:
- Overmixing the batter: This can lead to dense cake. Mix until just combined.
- Not cooling the cake properly: Allow the cake to cool before adding layers to prevent melting.
- Using cold ingredients: Ensure eggs and milk are at room temperature for a smoother batter.
Storage & Reheat Guide
To keep your Turtle Cake fresh and delicious:
- Storage: Cover the cake with plastic wrap or store in an airtight container. It can be stored in the refrigerator for up to 5 days.
- Reheating: Enjoy chilled, or warm individual slices in the microwave for about 10-15 seconds if you prefer a warm dessert.
