I initially printed this recipe in 2022 however just lately revisited it and retested it to see if I may enhance it. I at all times prefer to proceed to work on recipes, together with ones which have been printed and should not have the perfect opinions.
Within the case of this marble loaf cake recipe, some reviewers reported that it was dry or dense, not tall sufficient, and/or it lacked taste. After I see a sample of opinions with considerations over the identical factor, my group and I’ll revisit the recipe and take a look at making varied tweaks till we’re all assured that now we have mounted the problems that readers have been having.
After going again to the check kitchen, I’m proud to announce this marble loaf cake is best than ever! You’ll discover a couple of ingredient tweaks within the up to date recipe, together with including slightly baking soda and one other egg for further carry; and we’re swapping the entire milk and bitter cream for buttermilk, which provides further moisture to the cake crumb.

(But additionally, when you DO need that form of marble cake, do this 3-layer zebra cake, or the 2-layer marble cake in my cookbook, Sally’s Baking 101.)
Key Substances You Want for Marble Loaf Cake:

Let me clarify a number of the most necessary elements you want and why:
- Creamed Butter & Sugar: Like most cake recipes, the moist elements begin with room-temperature butter and granulated sugar to create a fluffy base. Study why this step is necessary on this publish on easy methods to cream butter and sugar.
- Buttermilk: A key moisture supplier that makes an enormous distinction within the texture of this cake. We strongly advocate utilizing store-bought buttermilk (both full-fat or low-fat), however in a pinch, you may make your individual buttermilk substitute with entire milk.
- Cocoa Powder: You want cocoa powder to make your chocolate batter. Bear in mind this publish on Dutch-process vs. pure cocoa powder? In testing this marble loaf cake, we discovered that utilizing Dutch-processed cocoa made for the perfect, smoothest-tasting chocolate taste. I normally use this model (not working with them, only a fan of the product!).
- Espresso Powder: Identical to in chocolate cake, we use espresso powder to boost and deepen the chocolate taste—it doesn’t style like espresso in any respect. You’ll find espresso powder within the espresso aisle at your grocery retailer or on-line.
Made From 1 Batter
The cake batter follows a easy, acquainted course of. Whisk the dry elements collectively, then, in a separate bowl, use a mixer to cream the butter and sugar collectively. Beat within the eggs and vanilla. Pour within the dry elements after which, with the mixer operating, slowly add the buttermilk.

The chocolate cake is made out of the vanilla batter, so that you don’t have to arrange two utterly separate batters. It’s how I put together the batters for this zebra marble cake, too. YAY!
Divide the batter into two bowls and add cocoa powder and espresso powder to at least one. Since we’re including these dry and bitter elements to the chocolate batter, it would dry out the cake. Slightly heat buttermilk solves that drawback. (Heat liquid helps the cocoa and espresso powders bloom/dissolve.) Each the vanilla cake and chocolate cake are so moist.
We did it!


Right here’s Precisely Swirl the Batters Collectively
- Unfold a skinny layer of the plain vanilla batter on the underside of the pan.
- Layer spoonfuls of every batter on high. Cowl backside vanilla layer with a couple of spoonfuls of the chocolate batter, then a couple of spoonfuls of the vanilla batter, then extra chocolate batter, then extra vanilla batter, and so forth till all the cake batter is used.
- Gently shimmy the pan to stage out the batters.
- Utilizing a knife, make rounded horizontal zig-zags from one facet of the pan to the opposite, after which make rounded vertical zig-zags from the highest to the underside. You can too use a toothpick to get slightly extra intricate with the marbling on high.




2-Ingredient Chocolate Ganache Topping
To high the cake, let’s flip to the fantastic dessert concoction often known as ganache. Chocolate ganache is often made with 1:1 semi-sweet chocolate and heavy cream or heavy whipping cream, however for this cake I needed a thicker-style ganache so I lowered the quantity of cream. As a result of there’s much less liquid, it’s finest to soften these two elements collectively reasonably than pour the nice and cozy cream over the chocolate like we normally do.
Let the ganache thicken for 20 minutes after which pour and unfold it over your cake. It’s superb! It’ll set right into a mushy fudge-like consistency after a pair hours, although you possibly can definitely benefit from the cake earlier than that!






Marble loaf cake has built-in magnificence with no difficult meeting or adorning abilities required. We will all respect that!
I hope you get pleasure from this new and improved model.
Description
You’ll love this buttery and moist marble loaf cake as a result of it’s stunning and spectacular with none fancy adorning abilities required. The chocolate batter is made out of the vanilla, so that you don’t have to arrange 2 separate cake batters from scratch.
Cake
Chocolate Ganache Topping
- Preheat the oven to 350°F (177°C) and generously grease a 9×5-inch loaf pan.
- Make the cake batter: In a medium bowl, whisk collectively the flour, baking powder, baking soda, and salt. Put aside.
- Utilizing a handheld or stand mixer fitted with a paddle attachment, beat the butter and sugar collectively on medium velocity till gentle and fluffy, about 5 minutes. Scrape down the perimeters and backside of the bowl with a silicone spatula as wanted. Add the eggs and vanilla and beat on excessive velocity for 1 minute. The combination could look a bit curdled at this level—that’s OK! Scrape down the perimeters and backside of the bowl as wanted. Pour the flour combination into the moist elements. Flip the mixer to low velocity and because the mixer runs, slowly pour in 3/4 cup + 2 Tbsp (210g/ml) of the buttermilk (reserve remaining 2 Tbsp (30g/ml)). Beat on low velocity simply till mixed. Don’t over-mix. You could have to whisk all of it by hand to ensure there aren’t any giant lumps on the backside of the bowl. The batter might be barely thick.
- You’ll have about 3–3.5 cups of batter. Switch rather less than half (simply eyeball it, doesn’t should be excellent) of the batter to a different bowl. Heat the reserved 2 Tablespoons of buttermilk within the microwave for 10–15 seconds. Stir the espresso powder into the nice and cozy buttermilk till dissolved, then pour it into the bowl that accommodates barely lower than half of the batter. Sprinkle the cocoa powder excessive, then stir, whisk, or beat on low velocity till mixed.
- Layer and swirl the batters: Unfold a skinny layer of the plain vanilla batter within the backside of your ready loaf pan. Now you’ll layer spoonfuls of every batter on high—cowl backside vanilla layer with a couple of spoonfuls of the chocolate batter, then a couple of spoonfuls of the vanilla batter, then extra chocolate batter, then extra vanilla batter, and so forth till all the cake batter is used. Gently shimmy the pan to stage out the batters. Utilizing a knife, make rounded horizontal zig-zags from one facet of the pan to the opposite, after which make rounded vertical zig-zags from the highest to the underside.
- Bake for 65–75 minutes, or till a toothpick inserted within the middle comes out clear. That point is a tenet—all ovens differ, so preserve an in depth eye on the cake after 55 minutes. If the cake is browning too rapidly on high earlier than the middle is totally baked, loosely tent a sheet of aluminum foil over high of the pan. (I at all times tent with foil after half-hour.)
- Cool the cake within the pan set on a cooling rack for half-hour, then take away the cake from the pan and place it instantly on the rack.
- Because the cake cools, make the ganache topping: Place the chocolate and cream in a medium heat-safe bowl set over a medium saucepan of simmering water. (Or use a double boiler if in case you have one.) Don’t let the underside of the bowl contact the water. Stir steadily till chocolate has melted and ganache is easy. Take away from warmth and put aside at room temperature for 20 minutes or till barely thickened.
- Drizzle or unfold topping on cake. Cake is scrumptious sliced and served barely heat. The topping units right into a fudge-like consistency after a number of hours.
- Cowl leftovers tightly and retailer cake (with or with out topping) at room temperature for as much as 3 days or within the fridge for as much as 1 week.
Notes
- Freezing Directions: Topped or plain cake freezes nicely for as much as 3 months. Wrap the cooled cake in a layer of plastic wrap, adopted by a layer of aluminum foil. Thaw in a single day within the fridge, then carry to room temperature or serve chilly. See Freeze Truffles for extra data.

- Room-Temperature Substances: All refrigerated gadgets needs to be at room temperature so the batter mixes collectively simply and evenly. Learn extra about room-temperature elements in baking.
- Buttermilk: Should you don’t have buttermilk, you may make a DIY buttermilk substitute. Add 2 teaspoons of white vinegar or lemon juice to a liquid measuring cup. Then add sufficient entire milk to the identical measuring cup till it reaches 1 cup. (In a pinch, lower-fat or nondairy milks work for this soured milk, however the cake gained’t style as moist or wealthy.) Stir it and let sit for five minutes. The selfmade “buttermilk” might be considerably curdled and able to use within the recipe.
- Espresso Powder: Espresso powder won’t make the cake style like espresso. As a substitute, it deepens the chocolate taste. You should use the identical quantity of on the spot espresso (the powder—not espresso grounds) as a substitute of espresso powder if desired.
- Chocolate: Ganache will solely set if the proper chocolate is used. You should use high-quality chocolate chips if wanted (I choose Ghirardelli or Guittard semi-sweet chocolate chips), however I like to recommend utilizing pure chocolate baking bars, in both semi-sweet or bittersweet. You’ll find them proper subsequent to the chocolate chips within the baking aisle. They’re bought in 4-ounce (113g) bars. I like Bakers or Ghirardelli manufacturers.
- Up to date in 2025: The recipe above is new and improved. Should you choose to make the unique model, anticipate a denser, flatter loaf. To make that older model, improve the baking powder to 1 and 1/2 teaspoons and skip the baking soda. Cut back the butter to 1/2 cup (8 Tbsp; 113g) and sugar to 1 cup (200g). Use 2 eggs. Skip the buttermilk and substitute with 1/4 cup (60g) bitter cream and a pair of/3 cup milk (160ml), plus 2 Tbsp milk for the chocolate batter. Observe the identical directions. The bake time is round 1 hour, identical oven temperature.
