Chocolate, Dulce de Leche and Vanilla Marble Cake

A trio of flavors combine in this stunning chocolate, dulce de leche and vanilla marble cake. Each slice reveals a swirled pattern of all these delicious flavors.

It’s rare that I find a recipe that’s perfect without any changes, but this marble cake impressed me after just the first bite, so much so that I had to share it with you right away. The cake is a special version of my chocolate vanilla marble cake, adding a swirl of dulce de leche to make it a triple threat of flavor.

The recipe comes from David Lebovitz, who adapted it from the original recipe featured in Bake from Scratch. I tested the recipe multiple times before sharing with you, each time being impressed by how such a simple cake could stun me. You can really taste each flavor — chocolate, dulce de leche, vanilla — in this triple marble cake. It’s the perfect cake to pair with a cup of coffee or to share with friends for a casual gathering or picnic.

Where to find dulce de leche?

Dulce de leche is a South American confection made of sweet milk that gets cooked down until it resembles a caramel sauce. It’s sweet and rich, which means it adds both sweetness and tenderness to the cake.

You can purchase cans of dulce de leche in supermarkets or on Amazon, but if you aren’t able to find it you can also make it at home with a can of sweetened condensed milk. David Lebovitz has an easy recipe on his blog where you bake a can of sweetened condensed milk for an hour to turn it into caramelized dulce de leche. You can make this ahead of time, storing it in the fridge until you’re ready to bake the marble cake.

How to make chocolate, dulce de leche and vanilla marble cake

Preheat your oven to 300ºF/150ºC and grease a loaf pan with butter or cooking spray. Both size loaf pans (8.5-inch or 9-inch) work for this marble cake recipe. I like to line the pan with parchment paper so that it hangs over the longer sides, which helps when removing the cake later.

In a stand mixer, beat the butter and sugar on medium-high speed until light and fluffy. This will take about 5 minutes and you will need to stop and scrape down the sides of the bowl occasionally. Make sure you take time on this step, since adding air to the butter and sugar results in a tender cake.

While the butter and sugar are beating, put the chopped chocolate in a bowl over simmering water and stir gently until it is smooth and melted. Turn off the heat and set this aside to cool slightly. You can also heat up the dulce de leche at this point, using the microwave in 30-second increments until it is soft and fluid. Make sure to transfer it out of the can and into a microwave-safe bowl!

Once the butter is light and fluffy, add the eggs at medium speed, one at a time, stopping the mixer to scrape down the sides after each addition. Whisk together the flour, salt, and baking powder in a small bowl. It may seem like a small amount of baking powder, but it gives the cake just enough height so it’s not dense.

Using a spatula, mix one-third of the dry ingredients into the butter mixture just until it’s almost fully mixed in. Stir in half of the sour cream or buttermilk, then the second third of the dry ingredients, the rest of the sour cream or buttermilk, and the final amount of the flour mixture. Make sure to stir each time only until everything is incorporated, and no more. You want to be very careful not to overmix the batter.

Dividing and flavoring the batters

Divide the plain batter into three equal portions, about 1 1/3 cups or 300 grams. Place one third in the bowl with the melted chocolate and cocoa powder, another in the bowl with the dulce de leche, and the final bit can remain in the mixing bowl.

Stir each portion until combined, adding in the vanilla extract to the third remaining in the mixing bowl. Be careful not to overmix the three batters when adding the flavors.

Making the checkerboard pattern

To get a fun pattern in the marble cake I like to scoop the batters in a checkerboard pattern, which I’ll explain below as well as share some photo guides. You don’t have to do this step, and you could just put the batters in a random way and swirl it all together with a toothpick, but I like the pattern the checkerboard provides.

If going the checkerboard route, use an ice cream scoop or 2 tablespoons (one spoon scoops and the other scrapes it off into the pan) to make five rows of chocolate and vanilla batter side-by-side in an alternating pattern down the sides of the pan. Add scoops of dulce de leche batter down the center of the pan.

For the second layer, create a checkerboard by putting scoops of chocolate batter over the scoops of vanilla batter in the pan, then putting scoops of dulce de leche batter over the scoops of chocolate batter in the pan. Finally, scoop the vanilla batter down the center of the pan. If you have any leftover batter just place scoops of it randomly on top.

Tap the pan lightly on the counter to settle the batters and get rid of any air bubbles. Swirl the batters together with a toothpick or knife about seven times, just so they mingle together but don’t combine.

Bake the marble cake for 1 hour and 30 minutes, until the center is set and a toothpick comes out clean. Let the cake cool in the pan for 15 minutes before removing to a wire rack to cool completely. The caramel marble cake is best enjoyed in the first two days at room temperature, but it also freezes really well if you have any extra!

---

Ingredients

• 170 g (1½ sticks/6 oz.) unsalted butter, at room temperature
• 1 1/2 cups (300g) granulated sugar
• 60 g (2¼ oz.) semisweet or bittersweet chocolate, chopped
• 1/4 cup (80g) dulce de leche
• 3 large eggs
• 1 1/2 cups (210g) all-purpose flour
• 1/2 teaspoon salt
• 1/4 teaspoon baking powder
• 1/2 cup (120 ml) sour cream or buttermilk (heavy cream works great, too)
• 1 tablespoon Dutch process cocoa powder
• 2 teaspoons pure vanilla extract

Instructions

1. Preheat the oven to 300ºF/150ºC. Grease well a 8.5×4.5-inch loaf pan (a 9-inch loaf pan works, too) with butter or cooking spray. You can line the pan with parchment paper so it’ll fit in the cake pan with overhanging edges (overhanging the longer sides) which will help you get the cake out later.
2. In the bowl of a stand mixer fitted with the paddle attachment, beat the butter and sugar on medium high speed until light and fluffy, about 5 minutes, stopping to scrape down the sides of the bowl as needed.
3. While the butter and sugar are beating, put the chopped chocolate in a medium bowl and set it over a pan of barely simmering water, stirring gently until smooth and melted. Turn off the heat and place aside.
4. Put the dulce de leche in a medium bowl and heat it in the microwave for about 30 seconds until it’s soft and fluid.
5. When the butter and sugar is light and fluffy, Add the eggs one at a time with the mixer on medium speed, stopping the mixer to scrape down the sides of the bowl after each addition. Whisk together the flour, salt, and baking powder in a small bowl.
6. Using a spatula, mix one-third of the dry ingredients into the butter mixture just until it’s almost all mixed in. (Don’t overbeat the batter when adding any of the ingredients during this step) Stir in half of the sour cream or buttermilk, then half of the remaining dry ingredients. Add the rest of the sour cream or buttermilk then the rest of the dry ingredients, stirring just until everything is incorporated, but no more.

7. Divide the batter into three portions; put one third (about 1 and 1/3 cups or 300 grams) in the bowl with the melted chocolate and stir them together along with the cocoa powder. Add another third of the batter in the bowl with the dulce de leche and stir until combined. Stir the vanilla extract into the remaining one-third of the batter in the mixing bowl. Be careful not to overmix.

8. Using an ice cream scoop or 2 tablespoons (using one spoon to scoop up the batter and the other to scrape it off, to release it and drop it into the loaf pan), make five rows of chocolate and vanilla batter side-by-side in an alternating pattern down both sides of the pan (as shown in the post). Add scoops of the dulce de leche batter down the center of the pan.

9. Working to create a checkerboard, for the next layer, put scoops of chocolate batter over the scoops of vanilla batter in the pan, then put scoops of dulce de leche batter over the scoops of chocolate batter in the pan. Finish (well, almost!) with scoops of vanilla batter down the center of the pan. Place scoops of leftover batters randomly on top. Tap the pan lightly on the counter to settle the batters.

10. Use a toothpick or butter knife to run it through the batter about seven times, so they’re mingling with each other (but don’t overdo it).
11. Bake the cake until the center is just set and a toothpick inserted into the center comes out clean, about 1 hour and 30 minutes.
12. Allow the cake to cool for 15 minutes in the pan, then use the parchment to lift the cake out of the pan and cool on a wire rack. Serve cake at room temperature.

13. Store cake for 2-3 days in the refrigerator. Serve at room temperature. The cake also freezes well. Thaw overnight in the fridge or for a couple of hours at room temperature.
