Step‑by‑Step Instructions for Dulce de Leche Mocha Cake
Step 1: Bake the Cake
Preheat your oven to 350°F (175°C). Butter and line the bottom of 4-6” or 2-8” cake pans with parchment paper. Sift together the all-purpose flour, unsweetened cocoa powder, baking powder, baking soda, and fine sea salt in a large bowl. In a separate bowl, cream the unsalted butter and sugar until light and fluffy, about 3-5 minutes. Add in the eggs, vanilla extract, milk, and hot brewed coffee, mixing until just combined. Pour the batter into prepared pans and bake for 15-20 minutes, checking for doneness with a toothpick.
Step 2: Make Dulce de Leche
While the cake bakes, you can prepare the dulce de leche. Place sealed cans of condensed milk in a pressure cooker, ensuring they are submerged in water. Cook on high for about 35 minutes; once done, carefully release the pressure and allow the cans to cool completely before opening. For convenience, you can use store-bought dulce de leche instead, but the homemade version adds a rich personal touch to your Dulce de Leche Mocha Cake.
Step 3: Prepare the Buttercream
Once your dulce de leche is ready, prepare the mocha swiss meringue buttercream. In a heatproof bowl, combine egg whites and sugar, whisking over simmering water until the mixture reaches 140°F (60°C). Remove from heat, and whip the mixture on high speed until stiff peaks form. Gradually incorporate softened butter, mixing well before adding melted chocolate, dulce de leche, and espresso powder. This luscious buttercream will add a creamy layer of flavor to the cake!
Step 4: Assemble the Cake
Carefully remove the cooled chocolate cake layers from their pans. Place one layer on a serving plate and pipe a ring of buttercream around the perimeter. Fill the center with a generous dollop of dulce de leche before topping with the second layer, repeating the process until all layers are stacked. For a smooth finish, apply a crumb coat of buttercream around the entire cake and chill for about 30 minutes to set.
Step 5: Make and Apply Ganache
To make the ganache, heat heavy cream to near boiling, then pour it over finely chopped chocolate. Stir until smooth and glossy, allowing it to cool slightly to thicken. Using a piping bag, drip the ganache around the edges of the cake, letting it cascade down. Spread any remaining ganache on top for a polished finish. Optionally, you can drizzle additional dulce de leche over the top for that extra touch of sweetness on your Dulce de Leche Mocha Cake.
Step 6: Chill and Serve
For the best flavor and texture, refrigerate your cake for a few hours or overnight before serving. This allows all the decadent layers to meld beautifully. When ready to serve, slice into the cake, and revel in the rich layers of chocolate, dulce de leche, and buttery mocha goodness. Don’t forget to pair it with a scoop of vanilla ice cream or a dollop of whipped cream for an indulgent treat!

Expert Tips for Dulce de Leche Mocha Cake
-
Chill Layers: Before stacking, chill your cake layers to firm them up. This prevents the layers from slipping and makes assembly easier.
-
Proper Mixing: Be careful not to overmix the cake batter once you add wet ingredients. This keeps the cake tender and avoids a dense texture.
-
Ganache Consistency: Allow the ganache to cool slightly before using. It should be pourable but not too runny for the perfect drip effect without making a mess.
-
Buttercream Temperature: If your buttercream seems too soft, refrigerate it briefly to thicken. This ensures easy piping and a beautiful finish on your Dulce de Leche Mocha Cake.
-
Check for Doneness: Always use a toothpick to check if the cake is done; it should come out clean. Avoid overbaking to keep the cake moist and flavorful.

Dulce de Leche Mocha Cake Recipe FAQs
What type of chocolate should I use for the ganache?
For the ganache, I recommend using high-quality chopped chocolate or chocolate chips with at least 60% cocoa content. This ensures a rich and luscious flavor. You can experiment with milk chocolate for a sweeter taste or dark chocolate for a more intense chocolate experience.
How can I tell when my cake layers are fully baked?
To check for doneness, simply insert a toothpick into the center of the cake layers. If it comes out clean or with a few moist crumbs (not wet batter), your cakes are perfectly baked! Remember, avoid overbaking, as it may lead to dryness—aim for a baking time of 15-20 minutes depending on your oven.
What’s the best way to store leftover Dulce de Leche Mocha Cake?
Store any leftover cake slices in an airtight container in the fridge for up to 4 days. This keeps them moist and flavorful. If you want it to last longer, wrap each slice tightly in plastic wrap and place them in a freezer-safe bag; they’ll stay fresh for up to 3 months.
Can I make the dulce de leche in advance?
Absolutely! You can make homemade dulce de leche ahead of time. After cooking the sealed cans of condensed milk, let them cool completely and store them in the fridge. Homemade dulce de leche will be safe to use for about 2-3 weeks, but be sure to keep it in an airtight container to maintain its creamy texture.
Are there any dietary considerations or substitutes I should be aware of?
If you have dietary restrictions, you can easily customize the recipe. For a gluten-free option, substitute all-purpose flour with a gluten-free baking blend. If you’re avoiding dairy, consider using plant-based butter and milk alternatives like almond milk or coconut cream. Just remember that while these substitutions may alter the flavor and texture slightly, the cake will still be delicious!
