Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

For the Cake
• 1 box chocolate cake mix (15.25 oz)
• 3 large eggs (or amount listed on box)
• 1/2 cup vegetable oil (or amount listed on box)
• 1 cup water (or amount listed on box)
• 1 cup semisweet chocolate chips
• 1 cup chopped pecans
• 1 can sweetened condensed milk (14 oz)
• 1 cup caramel sauce

For the Topping
• 1 1/2 cups caramel sauce
• 1 cup chocolate ganache or melted chocolate
• 3/4 cup chopped toasted pecans
• Optional: pinch of flaky sea salt

Directions

1. Preheat your oven to 350°F (175°C) or as directed on the cake mix box. Grease a 9×13-inch baking pan or line it with parchment paper.
2. Prepare the cake batter according to package instructions using eggs, oil, and water. Stir in the chocolate chips and half of the chopped pecans.
3. Pour the batter into the prepared pan and bake for 25 to 35 minutes, or until a toothpick inserted in the center comes out clean.
4. Let the cake cool for 5 minutes, then poke holes throughout the surface using the handle of a wooden spoon.
5. Pour the sweetened condensed milk evenly over the warm cake, allowing it to seep into the holes.
6. Drizzle 1 cup of caramel sauce over the cake while still warm so it absorbs easily. Let the cake cool completely.
7. Once cooled, spread 1 1/2 cups caramel sauce over the surface. Drizzle melted chocolate or ganache on top.
8. Sprinkle with toasted pecans and chill until the topping sets before slicing.

FAQs

How do I prevent the cake from becoming too soggy?

Use the full amount of condensed milk, but ensure the cake is still warm when pouring so it absorbs evenly without pooling.

Can I make this cake a day ahead?

Yes, the flavors deepen overnight, making it an excellent make-ahead dessert.

Do I have to toast the pecans?

Toasting enhances flavor, but you can use raw pecans if preferred.

What type of caramel sauce works best?

A thick, high-quality caramel sauce (store-bought or homemade) gives the best texture and shine.

Can I use a different cake mix flavor?

Yes—dark chocolate, devil’s food, or even chocolate fudge mixes work beautifully.

How do I get clean slices?

Chill the cake for at least an hour and use a sharp knife warmed in hot water, wiping between cuts.

Can I add extra toppings?

Yes—chocolate shavings, additional nuts, or a fine sprinkle of sea salt enhance presentation and flavor.

Can this be made gluten-free?

Yes, use a gluten-free chocolate cake mix and ensure all additional ingredients are certified gluten-free.

Will this work in two round cake pans?

Yes, divide the batter evenly and reduce the bake time slightly. Layer with caramel and chocolate between the cakes.

How long should the cake cool before adding toppings?

Allow the cake to cool completely after adding the caramel and condensed milk so the toppings set properly.
