    Why This Recipe Works

    • Soft layered cake- This cake has three cake layers that are super soft and moist!
    • Chocolate truffles- Since this cake is filled with your favorite chocolate truffles it is guaranteed to be amazing.
    • Chocolate frosting- This chocolate frosting is good enough to eat by itself and bring the cake to a new level.

    Ingredient Notes

    Here are some notes on the ingredients. For a full list of ingredients, check out the recipe card below.

    • Unsweetened cocoa powder- I strongly recommend dutch process cocoa powder for a more rich chocolate flavor. This is the one I used.
    • Oil- Use canola oil, vegetable oil, or olive oil.
    • Eggs- Pull the large eggs out 2 hours before baking.
    • Buttermilk- Use full fat or reduced fat buttermilk. Pull this out 2 hours before baking.
    • Hot water- The water needs to be steaming. The hot water helps to bloom the chocolate. You can also use hot coffee instead.
    • Unsalted butter- Pull this out 2 hours before using to reach room temperature.
    • Powdered sugar- Make sure to sift the powdered sugar to avoid a gritty frosting.
    • Chocolate bar- Make sure you use semi-sweet. I recommend a bar over chocolate chips as they will not melt as smoothly.
    • Chocolate truffles- I love Lindt chocolates, but you can substitute your favorite chocolate truffles as well.

    Step By Step Instructions-

    Here is how to make and bake this chocolate truffle cake

    For the cake layers, you don't need an electric mixer, it can be made by hand. For the frosting, use a stand mixer with a paddle attachment or a hand mixer.

    STEP 1: Melt the chocolate bars. Melt your chocolate in in a small bowl in 20 second intervals. Then, let it cool before using it.

    STEP 2: Mix the dry ingredients. First, sift the all-purpose flour, cocoa powder, baking powder, and salt in a medium bowl. Then, add the white sugar.

    STEP 3: Mix the wet ingredients. In a large bowl, mix the oil, vanilla extract, eggs, buttermilk, and melted chocolate using a whisk. Heat the water in a small saucepan until steaming.

    Then, slowly whisk in the hot water in.

    STEP 4: Pour. Pour the dry ingredients into the wet ingredients. Mix until just combined. Be careful not to overmix otherwise the cake can become tough.

    Then pour ⅓ of the cake batter evenly into each prepared pan with parchment paper and baking nonstick spray.

    STEP 5: Bake cake. Bake the cakes for 23-25 minutes until a toothpick inserted comes out clean

    Cool the cakes on a wire rack completely before decorating.

    STEP 6: Start the frosting. In a large mixing bowl, sift the powdered sugar and cocoa powder. Set that aside and use your mixer to beat the butter on high speed for 3 minutes.

    STEP 7: Beat frosting. Add in just half of the sugar chocolate mixture and mix on low speed until it starts to incorporate. Then add the rest of the sugar chocolate mix. Follow with the vanilla and salt. Beat it on high speed until the frosting is fluffy.

    Assembling the Cake Tips

    • Items that will be helpful in cake decoration: turntable, icing offset spatula, straight icing spatula, cake scraper, cake leveler (or a bread knife), and a cake carrier.
    • Cut the cake domes off of the chocolate cake layers by using a serrated knife. It needs to be as flat as possible.
    • Melt the 10 Lindt truffles in 20 second intervals. Make sure to be ready to use them before they cool and thicken.
    • Place the first chocolate cake layer down. Frost it with ¾ cup of frosting.
    • Drizzle half of the melted truffles on top and swirl them in with a butter knife.
    • Place your second layer on top. Frost with another ¾ cup of frosting and swirl in the remaining melted truffles.
    • Place the last cake layer with the bottom facing up make the top of the cake as flat as possible.
    • Frost the cake, including the sides of the cake, in a light layer of frosting and freeze for 15 minutes. This will set the frosting a provide a crumb coat to give a cleaner finish.
    • Frost the cake the rest of the way and top the frosted cake with your extra truffles.
    • Enjoy your decadent chocolate truffle cake!
