The first time I smelled the rich, chocolatey aroma of a freshly baked chocolate mayonnaise cake, I honestly thought someone was pulling my leg about the “mayonnaise” part. But let me tell you—it’s the secret ingredient that makes this cake so incredibly moist and tender, you’ll be hooked after the first forkful. I stumbled on this recipe during a rainy weekend when my pantry was running low on eggs and butter, and, well, let’s face it, baking emergencies lead to the best discoveries.
Chocolate mayonnaise cake is a classic that’s been passed down through generations, especially during times when eggs and oil were scarce (like the 1930s). It’s a dessert that’s both resourceful and downright delicious. I’ve made this cake for family birthdays, lazy Sunday afternoons, and even potluck dinners—each time, it disappears faster than you can say “chocolate.” The best part? You don’t need fancy ingredients or equipment, and there’s no complicated prep—just simple, everyday items and a few minutes to mix everything up.
If you’re searching for a homemade dessert idea that’s easy, crowd-pleasing, and a little bit nostalgic, chocolate mayonnaise cake is your answer. Whether you’re a busy parent, a college student with limited kitchen supplies, or someone who just loves good, old-fashioned chocolate cake, this recipe is going to become a staple in your kitchen. I’ve tested this cake more times than I can count and tweaked it for both flavor and simplicity. So, trust me—this cake is worth every bite!

Ingredients Needed for Chocolate Mayonnaise Cake
This recipe keeps things simple—just real, everyday ingredients that come together for amazing results. I love that you don’t need anything fancy, and there’s plenty of room to swap things based on what’s in your kitchen or your dietary needs.
- All-purpose flour – 2 cups (240g) (provides structure and softness)
- Cocoa powder – 2/3 cup (55g), unsweetened (choose a high-quality brand for deeper flavor)
- Baking powder – 2 teaspoons (helps the cake rise and stay fluffy)
- Baking soda – 1 teaspoon (gives extra lift and lightness)
- Granulated sugar – 1 1/4 cups (250g) (for sweetness and tender crumb)
- Mayonnaise – 1 cup (240g) (full-fat recommended; acts as the moistening agent and replaces eggs/oil)
- Whole milk – 1 cup (240ml) (can sub with almond or oat milk if needed)
- Vanilla extract – 2 teaspoons (for warmth and depth)
- Salt – 1/2 teaspoon (balances the flavors)
- Optional: 1/2 cup (120ml) hot coffee (enhances chocolate flavor, but water works too)
Topping suggestions:
- Chocolate frosting – classic, rich, and oh-so-satisfying
- Powdered sugar – for a simple, elegant finish
- Fresh berries – adds a pop of color and tartness
- Whipped cream – light and fluffy, balances the deep chocolate
If you’re short on an ingredient, don’t stress! You can swap whole milk with any non-dairy alternative, and use low-fat or olive oil mayonnaise for a lighter version. For gluten-free diets, a 1:1 gluten-free flour blend works well (I’ve tested with Bob’s Red Mill and it’s pretty spot-on). If you want a deeper chocolate flavor, add a pinch of espresso powder or use dark cocoa. The ingredients here are flexible, yet each plays a key role in getting that perfect homemade dessert texture and flavor.
Equipment Needed
You don’t need a fancy kitchen setup for chocolate mayonnaise cake. I’ve baked it in tiny apartments, at my mom’s house, and even in a borrowed beach rental using just the basics.
- Mixing bowls (one large, one medium) – For combining dry and wet ingredients separately.
- Whisk and spatula – A whisk helps with smooth batter, and a spatula is great for scraping every last bit.
- Measuring cups and spoons – Accuracy matters, especially for baking.
- 9×13-inch cake pan (23x33cm) – Standard for this recipe, but two 8-inch (20cm) round pans work too.
- Sifter or fine-mesh strainer – Helps avoid lumps in the cocoa and flour.
- Oven mitts – Safety first!
- Wire cooling rack – Speeds up cooling and keeps the cake from getting soggy.
If you don’t have a sifter, just use a fork to fluff up the flour and cocoa. For cake pans, I’ve used glass, metal, and even disposable aluminum trays (they all work, though metal gives the best crust). After baking, let pans soak with warm water for easy cleanup. Budget-wise, most tools here are under $10, and you can reuse them for dozens of recipes. Honestly, a sturdy whisk and a reliable cake pan make all the difference!
Preparation Method
- Prep the oven and pan: Preheat your oven to 350°F (175°C). Grease a 9×13-inch (23x33cm) cake pan lightly with butter or nonstick spray. Line the bottom with parchment paper if you want easy removal—otherwise, just grease well.
- Mix dry ingredients: In a large bowl, sift together 2 cups (240g) all-purpose flour, 2/3 cup (55g) unsweetened cocoa powder, 2 teaspoons baking powder, 1 teaspoon baking soda, and 1/2 teaspoon salt. Sifting is key for a smooth batter, but if you’re out of patience, just whisk until lump-free.
- Combine wet ingredients: In a medium bowl, whisk together 1 cup (240g) mayonnaise, 1 1/4 cups (250g) granulated sugar, 1 cup (240ml) whole milk, and 2 teaspoons vanilla extract. If using coffee, add 1/2 cup (120ml) hot coffee now for a richer chocolate flavor.
- Blend together: Pour the wet mixture into the dry ingredients. Stir gently with a spatula until just combined—don’t overmix, or the cake may turn dense. The batter should be thick but pourable; if it looks dry, add a splash more milk.
- Pour and smooth: Transfer batter to your prepared pan, smoothing the top with a spatula. Tap the pan lightly on the counter to release any big air bubbles.
- Bake: Place pan in the center of the oven and bake for 30-35 minutes. Start checking at 28 minutes—insert a toothpick in the center; it should come out clean or with just a few moist crumbs.
- Cool: Remove cake from oven and let it cool in the pan for 10 minutes. Then, run a knife around the edges and invert onto a wire rack to cool completely. (If you’re impatient, just leave it in the pan—no big deal, but cooling helps keep it moist.)
- Finish and serve: Once cooled, frost with chocolate icing, dust with powdered sugar, or pile on berries and whipped cream. Slice into generous squares and serve!
Troubleshooting tips:
- If your cake sinks in the middle, check oven temperature and avoid overmixing.
- If the batter looks curdled after mixing wet ingredients, don’t worry—it’ll smooth out once combined with flour.
<lia cake="" dry="" early!
For extra efficiency, measure ingredients ahead of time and have everything at room temperature. I sometimes make the batter in the morning and bake in the evening—no issues! The cake holds up well, and the flavors deepen overnight.
Cooking Tips & Techniques
After baking chocolate mayonnaise cake more times than I care to admit (including a couple of late-night experiments), I’ve picked up some tricks that really help.
- Sift dry ingredients: Cocoa and flour can clump—sifting makes the batter silky and helps the cake rise evenly.
- Use full-fat mayonnaise: Low-fat versions work, but the cake isn’t as moist. Trust me, the extra richness is worth it.
- Don’t overmix: Stir until just combined—if you keep mixing, the cake can turn rubbery.
- Watch baking time: Every oven’s a little different. Set a timer for 5 minutes before the minimum and check early. A toothpick should come out mostly clean.
- Cool completely before frosting: If you rush, the frosting will melt and slide off (been there, done that!).
- Flavor boosters: A splash of hot coffee or a pinch of espresso powder deepens the chocolate flavor without making it taste like coffee.
- Pan alternatives: If you don’t have the right pan, split the batter between two 8-inch round pans or even make cupcakes (adjust bake time to 18-22 minutes).
Common mistakes? Once, I forgot to sift the cocoa—result: little bitter lumps. Another time, I swapped full-fat mayo for light, and the cake was noticeably drier. Always check your pan size and avoid opening the oven too often. Multitasking tip: clean up while the cake bakes, and prep your toppings so everything’s ready when it comes out. Consistency is all about measuring carefully and keeping an eye on the oven!
Variations & Adaptations
One thing I love about chocolate mayonnaise cake is how adaptable it is. Depending on your tastes or dietary needs, you can totally customize it!
- Gluten-free version: Use a 1:1 gluten-free flour blend. I’ve tested Bob’s Red Mill and King Arthur—both work great with no weird texture.
- Dairy-free option: Swap whole milk with almond, oat, or soy milk. Vegan mayo works too, though the flavor is a touch different.
- Low-sugar version: Substitute half the sugar with a zero-calorie sweetener (like monk fruit or stevia blend). The cake might be a bit less tender but still delicious.
- Flavor twists: Add 1 tablespoon orange zest for a chocolate-orange vibe, or mix in 1/2 cup mini chocolate chips for extra gooeyness.
- Seasonal toppings: Try topping with roasted nuts in fall, fresh cherries in summer, or peppermint chips around the holidays.
One adaptation I really enjoyed was making cupcakes for my nephew’s birthday—same recipe, baked for 18 minutes, and topped with rainbow sprinkles. For allergies, always check the mayo label; some brands include egg or soy. If you want a lighter cake, try olive oil mayo—it gives a subtle flavor but keeps things moist. Experiment and make it your own!
Serving & Storage Suggestions
Chocolate mayonnaise cake is best served at room temperature—this way, it’s super moist and the chocolate flavor shines. Slice thick pieces and plate with a dollop of whipped cream or a handful of berries for a Pinterest-worthy dessert.
- Presentation: Cut into squares or rounds, dust with powdered sugar, and add fresh mint or fruit for color.
- Pairings: Perfect with coffee, milk, or even a scoop of vanilla ice cream. For special occasions, serve with raspberry sauce or caramel drizzle.
- Storage: Store in an airtight container at room temp for up to 3 days. For longer storage, keep in the fridge for up to a week (it stays moist!).
- Freezing: Wrap individual pieces tightly and freeze for up to 2 months. Thaw at room temp or microwave for 15-20 seconds.
- Flavor development: Honestly, the cake tastes even better the next day as the flavors meld together. Overnight is magic!
When reheating, use short bursts in the microwave or cover with foil and warm in a low oven (300°F/150°C) for 10 minutes. I like to freeze leftovers and sneak a piece after dinner—so good!

Cocoa provides antioxidants, and by using whole milk or non-dairy alternatives, you can tailor the cake to your dietary needs. This recipe is nut-free (unless you add toppings), but does contain gluten and eggs (from mayo). If you’re looking for a treat that feels indulgent but isn’t heavy, this is a great choice. I love that you can tweak it for lower sugar or gluten-free diets—makes dessert a little less guilty!
