This chocolate dulce de leche caramel turtle cake recipe is SO SO GOOD! It is decadent and delicious and perfect for a holiday-time treat or any time you want the best turtle cake you’ll ever have!!!
This chocolate turtle cake is a recipe that started as a recipe from one of Martha Stewart’s cookbooks on cake (<- just read somewhere this past weekend she has 98 cookbooks to her name, whoa). I love Martha Stewart’s Cake cookbook and Ben and I always make a chocolate cake recipe from it. Side note -you know it’s a good recipe because it always comes out good, even when baking with a toddler (which leaves plenty of room for error!) I took that inspiration from that cookbook/cake and took it to the next level by adding chocolate and caramel and pecans to turn it into a turtle cake!
She has some really great recipes and the simple chocolate cake is a great starting point. From there, I made up the most delicious frosting and toppings and put it all together into a chocolate dulce de leche caramel turtle cake.
What are the basic steps for making this cake?
You’ll bake the cakes first:
Spray two round cake pans with cooking spray.
Cut a circle of parchment paper and line the bottom of the cake pans and set aside. I like using Gold Touch pans.
Preheat oven to 350.
In a bowl add flour, baking soda and salt and set aside.
In another bowl with a hand or stand mixer, beat butter and granulated and brown sugar until fluffy, about 3 minutes. Beat in eggs and yolk 1 at a time. Beating well after each addition. Add in vanilla extract. Mix sour cream and milk together in a bowl.
Now alternating between the flour mixture and sour cream, add in alternating flour and sour cream/milk in batches (I did this in 3-4 additions starting and ending with flour – flour, sour cream/milk, flour, sour cream/milk, flour, sour cream/milk, flour), beating and incorporating in between each addition. Add in melted chocolate and beat again (I melted chocolate in the microwave in 30 second intervals).
Divide the batter evenly between the two prepared pans. Bake for 30-40 minutes, until a cake tester comes out clean out of the center. Transfer pans to a wire rack to cool for 20 minutes, then turn out cakes onto rack to cool completely.
Cut the domed top off cake to make a straight stacking layer.
Then prepare the thick chocolate frosting
Microwave chocolate chips (or chunks) in 30 second intervals, stirring in between until melted (mine usually takes 2 minutes). Be careful to stir in between and not overcook. Cut butter into cubes (about 1 tablespoon per cute) and put butter on top of melted chocolate and stir until all the butter is melted.
With a hand or stand blender, slowly blend in powdered sugar.
And last comes the assembly:
Put bottom cake layer (with domed top cut off) on a cake stand or plate.
Spread 1/3 of the frosting on the top of the cut off layer. Add 1/2 cup caramel sauce and 1/2 cup chopped candied pecans.
Place the second cake on top. Use the remaining frosting to frost the top and sides of cake. Add remaining pecans and sprinkle around the top. Use the caramel to drizzle around the edges or in a zig zag pattern on top.
Slice and enjoy!
And like the homemade chocolate birthday cake and chocolate layer cake, this chocolate cake is made with sour cream. Sounds funny right? But there is certainly something to be said about a good chocolate cake made with sour cream (something I’d literally never heard of until I started baking homemade chocolate cakes a few years ago, as an adult).
Not only is this cake decedent, but it’s large. So I would say it comfortably serves 10-12 people.
Oh and the chocolate dulce de leche caramel turtle cake recipe makes a great chilled cake too. It’s actually super good if you put it in the fridge so the frosting gets a little cool. Yum!
Dulce de leche is thick caramel sauce, you could use store bought dulce de leche or a rich goat’s milk caramel, like this one (you can use code SWEETPHI for $1 off that caramel).

Where was the milk added? Maybe I missed it’.
Sweetphi says
So sorry, just updated the recipe card – the milk is added with the sour cream!
Jennifer Reinsch says
I just mixed up the batter which is in the oven, but I’m worried as it tasted super salty. Is it really 2 1/2 t salt??
Sweetphi says
Thank you so much for the comment. Yes, it is 2 1/2 teaspoons salt, the recipe was adapted from a Martha Stewart chocolate cake recipe, it evened out the sweetness but it definitely wasn’t salty when I’ve made this!! Fingers crossed that with the frosting and caramel it’ll be perfect for you!!
monika says
what SIZE are the round pans?
Seems like an important thing to leave out…
Sweetphi says
9 inch cake pans, thanks for the feedback, I’ll definitely add it to the recipe.
Sabrina says
very nice, love these flavors in a cake – chocolate and caramel – and love the “turtle” toppings too, thank you!
