Why We Love This Recipe
- Chocolate cake: I used the same chocolate cake recipe that I used to make my mini chocolate cake. It’s rich, delicious and is so easy to make.
- Dulce de leche buttercream frosting: I have been wanting to make this cake since I made these incredible dulce de leche cupcakes. They are topped with the most flavorful dulce de leche buttercream. I knew it would also be the perfect frosting for a chocolate cake!
- Olive oil makes baked goods so rich and moist. One of my favorite olive oil bakes is this flavorful Lemon Rosemary Olive Oil Cake!
YOU CAN BUY DULCE DE LECHE
I find it in the baking aisle near the sweetened condensed milk in most grocery stores where I live. You may also find it in the international foods aisle.
YOU CAN MAKE IT AT HOME
If you can’t find dulce de leche in the store, you can make your own. Cooking sweetened condensed milk is the easiest way, but you can also make it completely from scratch with milk and sugar. Preppy Kitchen has a thourough post on how to make dulce de leche.
Ingredients
- Olive oil: Olive oil provides moisture and flavor. It’s best to use a good quality extra virgin olive oil.
- Granulated sugar
- Brown sugar: Use light or dark packed brown sugar. Make sure your brown sugar is fresh.
- 1 egg: Use 1 large room temperature egg.
- Buttermilk
- All purpose flour
- Cocoa powder
- Butter-Use unsalted, room temperature butter for the frosting.
- Dulce de leche: I use store bought dulce de leche for this frosting. Dulce de leche is a confection that’s popular throughout Latin America. It’s made by slowly heating sweetened condensed milk til develops a rich caramel color and flavor. It’s thick, luscious and so irresistibly good!
Substitutions And Variations
- Canola or vegetable oil can be used instead of olive oil.
Instructions
- Preheat oven to 350 F and line two 6″ straight edge cake pans with parchment paper. Spray the sides with cooking spray.
- Whisk to combine the flour, cocoa powder, baking powder, baking soda, and salt in a large bowl then set aside.
- In a medium sized bowl, whisk the egg, oil, sugars, buttermilk and vanilla extract until combined.
- Stir the wet ingredients into the dry ingredients then pour in the hot water and stir until just combined.
- Pour the batter into the pans and bake 28-32 minutes or until a toothpick comes out clean. Cool completely before frosting.
HOW TO MAKE DULCE DE LECHE FROSTING
- Cream the butter with an electric mixer on medium speed for one minute. Add the sifted powdered sugar and beat on medium for 3-4 minutes, until creamy. Add the heavy cream or milk. Slowly beat in the dulce de leche a little bit at a time. Beat in the vanilla followed by the salt.
- If buttercream is too thin, add more powdered sugar, if it is too thick, add more milk or heavy cream until it is the consistency you desire. To firm buttercream up a bit more before frosting, cover it with plastic wrap and refrigerate it for 20-30 minutes.
TIPS FOR MAKING BUTTERCREAM FROSTING
- Use Room Temperature Butter: I leave my butter out overnight in the wintertime. The amount of time you leave it out depend on the temperature of your kitchen. To be on the safe side, allow butter to sit out for at least 1-2 hours before using it.
- Add More Powdered Sugar: If you find your buttercream is too thin, gradually add more powdered sugar to thicken it.
- Add More Heavy Cream or Milk: If you find your buttercream is too thick, very gradually add more heavy cream or milk. By gradually, I mean a little splash (around a teaspoon) at a time. Definitely don’t add a whole tablespoon at a time.
HOW TO ASSEMBLE THE CAKE
PREPARE THE CAKE LAYERS
Make the cakes and allow them to cool. Once cooled, tuse a long serrated knife to slice off just the top of your cakes. This will give you even layers.
HOW TO ASSEMBLE THE CAKE
Frost the top of the first layer with the frosting. Drizzle with a little extra dulce de leche if desired. Place the top layer cut side down on top. Frost with frosting and enjoy!
Recipe FAQs
Dulce de leche means sweet or candy of milk in Spanish. The ce in dulce sounds like an s and the e at the end of the words is not like ee. It’s like eh. It’s pronounced dool seh deh lehcheh.
I recommend using layer cake pans because they have perfectly straight sides. I use two 6 by 2 inch pans.
Store the unfrosted cake in an airtight container at room temperature for 2-3 days.
Once the cake is frosted, I recommend storing it an airtight container in the chocolate and dulce de leche cake in the refrigerator for 3-4 days.
Freeze unfrosted cake in an airtight container for up to 2 months. Thaw in the refrigerator.
