Ingredients for hellmann's chocolate mayonnaise cake
Eight simple ingredients transform into decadent, fudgy chocolate cake layers—no box mix needed.
| Ingredient | Amount | Notes |
|---|---|---|
| Hellmann's Mayonnaise 🥛 | 1 cup | Full-fat for best texture |
| Unsalted Butter 🧈 | 1 cup | Softened, room temperature |
| Granulated Sugar 🍚 | 2 cups | White or light brown |
| Unsweetened Cocoa Powder 🍫 | ¾ cup | High-quality, Dutch-processed |
| Large Eggs 🥚 | 2 whole | Room temperature preferred |
| Vanilla Extract 🌿 | 2 tsp | Pure, not imitation |
| All-Purpose Flour 🌾 | 2 cups | Sifted for smooth batter |
| Baking Powder 🧂 | 1 ½ tsp | Freshly opened package |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Hot Water 💧 | ½ cup | For blooming cocoa |
| Milk 🥛 | ¼ cup | Whole milk for richness |
The mayonnaise is the star here, so Hellmann's is non-negotiable—it's what gives this cake that signature moist, velvety texture. Grab the full-fat version, not the light kind. The butter should be soft but not melted—press a finger into it and it should leave a slight indent. For the cocoa, Hershey's Special Dark or Ghirardelli are my go-tos, but any high-quality Dutch-processed powder works. Eggs? Room temperature makes all the difference—they'll blend smoother and help create that perfect crumb. I always buy eggs from Trader Joe's or Costco for the freshest flavor.
No vanilla extract? Vanilla bean paste works in a pinch, or even a scraped vanilla bean. The milk can be swapped for heavy cream if you want extra richness, but whole milk keeps it balanced. For the sugar, light brown sugar adds subtle molasses notes, but white sugar keeps it classic. The baking powder needs to be fresh—if it's been sitting in your pantry for months, it's time for a new box. And if you're out of milk, water plus a splash of vanilla gets you close, though the cake won't be quite as tender.
This cake keeps beautifully—3-4 days wrapped at room temperature or 1 week in the fridge. For serving, I like to dust with powdered sugar or add a dollop of whipped cream. Leftovers reheat well in the microwave—10 seconds per slice brings back that warm, gooey goodness. The layers stay moist for days, so it's perfect for making ahead. Store any extra in an airtight container with a slice of bread to keep it fresh longer.

Instructions for Hellmann's chocolate mayonnaise cake recipe
Here's how to make this rich, fudgy cake with perfect layers every time.
Prepare the Chocolate Cocoa Mixture
In a medium saucepan, combine the 0.75 cup unsweetened cocoa powder, 2 cups granulated sugar, and 0.5 cup hot water. Stir over medium heat until completely dissolved and smooth—this should take about 2-3 minutes. You'll see the mixture thicken slightly as the cocoa blooms fully. Remove from heat and let cool for 5 minutes while you prepare the butter mixture.
This step is crucial because properly blooming the cocoa ensures maximum flavor extraction. If you see any lumps, strain the mixture through a fine-mesh sieve for a silky texture. The cooled mixture should be thick enough to coat the back of a spoon but still pourable.
Cream Butter and Mayonnaise Together
In a large mixing bowl, beat the 1 cup softened unsalted butter and 1 cup Hellmann's mayonnaise together on medium speed for 2-3 minutes until completely smooth and lightened in color. This step creates the cake's signature tender, moist crumb. Scrape down the sides of the bowl with a rubber spatula to ensure even mixing.
I like to use a hand mixer for this part because it gives me more control over the speed. The mixture should be thick but still spreadable—almost like a thick frosting. If it looks too stiff, let it sit at room temperature for 5 minutes to soften slightly before proceeding.
Combine Wet Ingredients
Gradually add the cooled cocoa mixture to the butter-mayonnaise blend, mixing on low speed until fully incorporated. Then add the 2 whole large eggs, one at a time, mixing just until each is fully combined. Stir in the 2 teaspoons vanilla extract and set the bowl aside.
This is where the magic happens—the mayonnaise and butter create an incredibly tender base while the chocolate mixture adds deep cocoa flavor. The eggs help bind everything together while keeping the cake moist. Don't overmix here—just until everything is combined and smooth.
Fold in Dry Ingredients
In a separate bowl, whisk together the 2 cups all-purpose flour, 1.5 teaspoons baking powder, and 0.5 teaspoon salt. With the mixer on low speed, gradually add the dry ingredients to the wet mixture, mixing just until combined. Be careful not to overmix—the batter should be thick but still pourable, with no visible flour streaks.
For best results, I recommend using a spatula to gently fold in the last bit of dry ingredients by hand. This helps prevent overdevelopment of gluten, which would make the cake tough instead of tender. The final batter should be thick enough to hold its shape when dropped from a spoon but still smooth.
Bake the Cake Layers
Preheat your oven to 350°F. Grease and flour two 8-inch round cake pans or line them with parchment paper. Divide the batter evenly between the pans and smooth the tops. Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean. The edges should be set but the centers should still look slightly underbaked—they'll firm up as they cool.
I like to rotate the pans halfway through baking for even browning. The cake should pull away slightly from the edges of the pan when done. Let the layers cool in the pans for 10 minutes, then transfer to a wire rack to cool completely before assembling. This cooling step is important—it prevents the layers from becoming soggy when you add the filling.
Assemble the Cake
Once completely cool, level the tops of the cake layers if needed. For the filling, beat the 0.25 cup milk with 2 tablespoons granulated sugar until smooth, then spread evenly between the layers. You can also add a simple chocolate buttercream if you prefer a sweeter filling.
The milk mixture creates a light, creamy filling that complements the rich chocolate flavor without overpowering it. If you're using the milk-only filling, it will soak into the cake slightly, making each slice incredibly moist. Wrap the assembled cake and refrigerate for at least 1 hour before slicing to let the flavors meld together.
Pro Tips For Making Hellmann'S Chocolate Mayonnaise Cake
- Whisk Eggs First: Crack the eggs into a separate bowl first, then whisk them vigorously until the whites and yolks are fully combined and slightly frothy. I learned this the hard way—adding eggs directly to the mayo mixture often leads to lumps, and you don’t want a grainy cake. The extra 30 seconds of whisking makes all the difference.
- Melt Butter Slowly: Warm the butter in a saucepan over low heat until it’s just melted—no higher than 160°F (70°C)—then let it cool slightly before mixing it into the batter. After burning three batches, I finally figured out that hot butter can curdle the mayo, turning your rich cake into a sad, separated mess.
- Sift the Cocoa: Sift the unsweetened cocoa powder directly into the dry ingredients (if your recipe calls for mixing it in) to avoid clumps. I was skeptical until I tried it—this cake relies on even distribution, and cocoa lumps show up like dark splotches in an otherwise smooth batter.
- Don’t Overmix the Batter: Combine the wet and dry ingredients just until the cocoa is mostly incorporated—overmixing introduces too much air, which can cause the cake to sink or develop a dense texture. Stir until the batter looks thick and slightly streaky, then stop. Your future self will thank you.
Make-ahead tips for this dish
Prep Ahead Strategy
This cake is perfect for making ahead—prepare the batter up to 24 hours in advance and store it in an airtight container in the refrigerator. The flavors actually deepen overnight, and the batter will be perfectly chilled for baking.
I like to mix everything the night before so I can focus on baking fresh in the morning. 💫
Bake and Store Layers
Bake the cake layers as directed, then let them cool completely before storing. Wrap each layer individually in plastic wrap and place them in a ziplock freezer bag for up to 3 days at room temperature or 1 week in the fridge.
For longer storage, freeze the layers for up to 2 months—thaw at room temperature before assembling. This method keeps the layers perfectly moist.
Assemble When Ready
When you're ready to serve, simply assemble the cake with your preferred filling (the milk mixture or buttercream). The cake will need 1-2 hours in the fridge to set properly after assembly.
I often make the filling fresh the day of serving to ensure maximum creaminess, but you can also prep it ahead and store it separately in the fridge.
Serving Suggestions
For a restaurant-worthy presentation, dust the top with powdered sugar or drizzle with chocolate ganache. Serve slices at room temperature for the best texture. The cake keeps well for 3-4 days when properly stored, so it's perfect for meal prep.
I like to pack individual slices in parchment-lined containers for easy grab-and-go dessert options. 🍫
Freezing Fully Assembled
If you want to freeze the fully assembled cake, wrap it tightly in plastic wrap followed by aluminum foil. Place it in a freezer-safe container and freeze for up to 2 months.
Thaw in the fridge overnight before serving. The texture remains moist, though the filling may separate slightly—just stir it gently before serving. This is my go-to method for holiday desserts!
Make-Ahead Filling
For extra convenience, make the milk-based filling in advance and store it in a small jar in the fridge for up to 5 days. Stir well before using, as it may separate slightly.
If you prefer buttercream, make it a day ahead and store it in the fridge—bring it to room temperature before spreading between layers. This ensures your cake stays perfectly moist and delicious whenever you're ready to serve. 💡

Frequently asked questions
Why does this cake use mayonnaise instead of oil?
The mayonnaise creates a signature tender, moist crumb that's impossible to achieve with oil alone. It acts as both a fat source and a natural tenderizer, keeping each slice rich and velvety. The slight tang from Hellmann's also balances the chocolate's sweetness for a more complex flavor profile.
Can I substitute Hellmann's with another brand?
While Hellmann's is ideal for its full-fat consistency, you can use other full-fat mayonnaise brands like Best Foods or Duke's. Avoid light or "fat-free" versions—they won't provide the same rich texture. The fat content is crucial for that signature moistness.
How do I fix a cake that's too dense or dry?
If your cake turns out dense, you likely overmixed the batter or didn't use enough mayonnaise. For dryness, try adding 1 tablespoon milk to the batter or brushing layers with simple syrup before assembling. Always use room-temperature ingredients and don't overbake—pull the cake when a toothpick comes out with moist crumbs.
What's the best way to store leftovers?
Wrap individual slices in plastic wrap and store in an airtight container at room temperature for 2 days or refrigerate for up to 5 days. For longer storage, freeze slices for 2 months. To reheat, microwave for 10-15 seconds or warm in a 300°F oven for 5 minutes covered with foil.
Can I make this cake gluten-free?
Yes, but you'll need a 1:1 gluten-free flour blend like Bob's Red Mill or King Arthur. Replace the all-purpose flour and add 1 teaspoon xanthan gum to improve texture. Keep other ingredients identical, but expect slightly denser layers. Test with a small batch first to adjust moisture levels.
