Keto Dulce de Leche Cake Recipe


If you’re a fan of indulgent desserts and following a ketogenic diet, then this keto dulce de leche cake recipe is perfect for you. This delectable treat combines the richness of dulce de leche with the low-carb, high-fat principles of the keto diet. In this article, we will guide you through the steps of making this heavenly dessert, ensuring a delightful and guilt-free experience.

Understanding the Keto Diet

Before we dive into the recipe, let’s briefly understand the keto diet. The ketogenic diet is a low-carb, high-fat eating plan that aims to shift the body into a state of ketosis. Ketosis is a metabolic state where the body utilizes fats as its primary source of energy instead of carbohydrates. By limiting carb intake and increasing fat consumption, the keto diet promotes weight loss and provides various health benefits.

What is Dulce de Leche?

Dulce de leche is a popular Latin American caramel-like sauce made by slowly heating condensed milk until it thickens and develops a rich, caramel flavor. Traditionally, dulce de leche is high in sugar and not suitable for a keto diet. However, with a few simple modifications, we can create a keto-friendly version of this delectable sauce.


Before we start baking, let’s gather the necessary ingredients:

  • 1 cup almond flour
  • 1/4 cup coconut flour
  • 1/4 cup unsweetened cocoa powder
  • 1/2 cup granulated erythritol (or your preferred keto-friendly sweetener)
  • 1 teaspoon baking powder
  • 1/4 teaspoon salt
  • 4 large eggs
  • 1/2 cup unsalted butter, melted
  • 1/4 cup unsweetened almond milk
  • 1 teaspoon vanilla extract
  • 1/2 cup keto-friendly dulce de leche sauce (store-bought or homemade)


Making the Dulce de Leche Sauce

To create the keto-friendly dulce de leche sauce:

  1. Start by preheating your oven to 425°F (220°C).
  2. Pour a can of unsweetened condensed milk into a glass baking dish.
  3. Cover the dish with aluminum foil and place it inside a larger baking pan.
  4. Fill the larger pan with hot water, ensuring the water level is halfway up the side of the smaller dish.
  5. Bake the condensed milk in the water bath for about 2 hours, or until it turns a golden caramel color.
  6. Remove the dish from the oven and let the dulce de leche sauce cool.

Preparing the Cake Batter

Now, let’s move on to preparing the cake batter:

  1. Preheat your oven to 350°F (175°C) and grease a round cake pan.
  2. In a large mixing bowl, combine the almond flour, coconut flour, cocoa powder, erythritol, baking powder, and salt.
  3. In a separate bowl, whisk together the eggs, melted butter, almond milk, and vanilla extract.
  4. Pour the wet ingredients into the dry ingredients and mix until a smooth batter forms.
  5. Transfer the batter to the greased cake pan and smooth the top with a spatula.

Assembling the Cake

To assemble the keto dulce de leche cake:

  1. Drizzle half of the dulce de leche sauce over the cake batter.
  2. Use a toothpick or skewer to swirl the sauce into the batter, creating a marbled effect.
  3. Place the cake in the preheated oven and bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
  4. Once baked, remove the cake from the oven and let it cool in the pan for 10 minutes.
  5. Transfer the cake to a wire rack and let it cool completely.
  6. Drizzle the remaining dulce de leche sauce over the cooled cake, spreading it evenly.

Tips and Variations

  • For added crunch, sprinkle chopped toasted nuts over the cake before baking.
  • Feel free to experiment with different keto-friendly sweeteners to suit your taste preferences.
  • You can also incorporate a layer of whipped cream between the cake layers for extra indulgence.

Serve the keto dulce de leche cake as a delightful dessert or as a special treat for occasions. Store any leftovers in an airtight container in the refrigerator for up to 5 days. Before serving, allow the cake to come to room temperature or gently warm it in the microwave for a few seconds.
