    There's nothing better than a big slice of chocolate cake! This chocolate mascarpone layer cake with rich chocolate mascarpone frosting is truly decadent. It's based on my viral chocolate ganache cake but with layers and a creamy chocolate mascarpone frosting. Deep chocolate and smooth mascarpone is a dream pairing!

    The texture is soft and moist, making each bite so delicious. It was so good that my family ate the whole thing in 3 days! This beautiful cake is great for birthdays, anniversaries, or any celebration where you want to impress your guests with something delicious yet easy to make.

    Why You'll Love This Recipe

    • Rich chocolate flavor: Using brewed coffee and Dutch cocoa powder is my top bakery tip for creating a rich, indulgent cake. I've used the same technique in this chocolate cake with cream cheese frosting and chocolate lemon cake!
    • Super moist cake: It stays moist for days without drying out because of the sour cream and oil!
    • Chocolate mascarpone frosting: The slight tang of mascarpone cheese pairs perfectly with this fudgy cake. It also makes the buttercream so smooth and silky.

    Key Ingredients

    Ingredients to make a chocolate cake in bowls on a brown surface.

    Ingredients for the cake layers.

    Ingredients to make chocolate mascarpone frosting on a tan surface.

    Ingredients for the chocolate mascarpone frosting.

    • Cocoa powder- I prefer Dutch-processed cocoa powder in the cake and frosting for its deep, rich flavor. Natural (also called unsweetened) cocoa powder or even black cocoa will work.
    • Brewed coffee- Use any kind of coffee or espresso since you can't taste it in the cake. It just deepens the chocolate flavor. Make sure it's hot to allow the cocoa to bloom and break up clumps.
    • Oil- Canola, avocado, and vegetable oil are the best flavorless oils to keep the cake moist and soft.
    • Eggs- Large eggs help the ingredients hold together. Make sure they're room temperature so they mix in evenly.
    • Sour cream- Adds moisture without thinning out the cake batter. It makes the texture dense yet moist! Make sure it's room temperature so it mixes in smoothly.
    • All purpose flour- Makes up the structure of our cake and creates a tender crumb.
    • Baking powder and baking soda- These leaveners work together to make the cake rise. Make sure to check the expiration date because they aren't very effective if expired.
    • Butter- Salted or unsalted butter adds a rich flavor and gives the buttercream more structure. Pull it out of the fridge 1-2 hours before baking to reach room temperature.
    • Mascarpone cheese- Mascarpone is a rich, creamy Italian cheese known for its smooth texture and mild, slightly sweet flavor. Commonly used in mascarpone cheesecake and tiramisu, it makes frosting silky smooth and easy to spread and pipe with a subtle tang. Make sure it's room temperature so it's easy to mix with the butter.

    Substitutions and Variations

    • Coffee: Feel free to use decaf coffee if you're concerned about caffeine. Not a coffee drinker? You can use hot water! I tested this recipe with both water and coffee and each was delicious.
    • Sour cream: Plain Greek yogurt it the best substitute. Regular plain yogurt works too.
    • Mascarpone: Cream cheese is the best substitute here! The frosting will be a little more tangy, but still delicious.
    • Replace the cocoa powder in the frosting with an equal amount of icing sugar for a vanilla mascarpone frosting.
    • You can easily swap out the mascarpone buttercream for a different icing. I recommend this chocolate fudge frosting, whipped chocolate buttercream, Oreo cream cheese frosting, or whipped chocolate ganache!

    Helpful Equipment and Tools

    I recommend non-stick metal round cake pans in all my cake recipes because they heat up more evenly than glass or silicone pans.

    I recommend using an offset spatula and bench scraper to apply the frosting smoothly. If you don't have either, you can spread the frosting on with a butter knife or the back of a spoon.

    Step by Step Instructions

    Before starting to bake, preheat the oven to 350ยฐF. Line 3 6-inch cake pans with parchment paper and brew your coffee so it's nice and hot.

    Step 1: Whisk the cocoa powder and hot coffee together in a large bowl to bloom the cocoa.

    Step 2: Whisk in the vegetable oil, sugar, eggs, and sour cream vigorously until combined.

    Step 5: Let them cool in the pans for about 10 minutes. Loosen the sides with a butter knife and turn them over on a wire rack to cool completely.

    Step 6: To assemble, make the chocolate mascarpone frosting, then spread ยฝ cup frosting on top of one cake layer. Repeat with the second layer.

    Step 7: Place the last layer on top with the flat side up. Spread a smooth, thin layer of buttercream, also called a crumb coat, on top of the cake and down the sides.

    Chill for 20 minutes or until the frosting is dry to the touch.

    Step 8: Apply a final coat of frosting. Decorate with piping, chocolate chunks, or a drizzle of melted chocolate or ganache if desired.

    Expert Baking Tips

    1. Use room temperature ingredients. This ensures a smooth batter that bakes up evenly. The dairy ingredients and eggs should come out of the fridge 1-2 hours before starting.
    2. Measure the flour correctly. Measuring in grams with a kitchen scale is best for accuracy! It's easy to pack flour into measuring cups, which can make your cake dry.
    3. Bloom the cocoa. Combining cocoa powder with strongly brewed hot coffee releases even more chocolate flavor. Don't skip this step!
    4. Let the layers cool completely. I know it's hard to wait, but the cake layers need to be cool so the mascarpone frosting doesn't slide off.

    Storage Tips

    Store the chocolate mascarpone cake in an airtight container or wrapped in plastic wrap in the refrigerator for up to 5 days. You can store individual slices or the whole cake.

    The cake stays moist longer if you store it whole. Cover the cut section with extra frosting to keep it from drying out.

    Freezing Instructions

    To freeze the cake whole, first chill it in the refrigerator until firm. Wrap it in plastic wrap followed by a layer of aluminum foil. Freeze it for up to 3 months.

    For freezing cake slices, wrap each slice tightly in plastic wrap and then place them in an airtight container or freezer bag. Freeze for up to 3 months.

    Frequently Asked Questions

    Can I make this cake gluten free?

    Yes! Use a 1-to-1 gluten freeย flour (like Cup4Cup)ย to make it gluten free. Don't use almond flour or any other alternative flours since they'll change the texture!

    What other pans can I use?

    This recipe works in 2 8-inch or 9-inch cake pans or a 9x13-inch pan for a sheet cake.

    Can I make this into cupcakes?

    Yes, this recipe makes great chocolate cupcakes! Bake them at 350ยฐF/180ยฐC for 18-20 minutes.
