This all-in-one cake recipe transforms baking day into a streamlined, stress-free experience—no mixing bowls, no extra pans, just one container for batter, filling, and frosting. The secret lies in a foolproof single-bowl method where layers, custard, and cream cheese frosting come together without the usual chaos. I perfected this after years of cake disasters (and one very sticky kitchen counter), and it now delivers restaurant-quality results with minimal cleanup.
The magic happens in stages: you'll bake a tender vanilla cake in one bowl, prepare a silky custard filling in the same container, and whip up a velvety cream cheese frosting without switching tools. This isn't just a shortcut—it's a game-changer for home bakers who dread layering or frosting mishaps. The cake stays moist for days, the filling adds richness without sogginess, and the frosting holds its shape like a pro.
What you'll end up with is a multi-layered masterpiece that looks impressive but requires zero advanced skills. The vanilla cake layers remain perfectly tender, the custard filling stays luscious without curdling, and the frosting swirls like something from a bakery. Best of all? The entire process takes under 2 hours from start to finish, including cooling and assembly.
Whether you're hosting a birthday, celebrating a milestone, or just craving dessert, this recipe delivers foolproof layers every time. The best part? One bowl means one less dish to wash—because even professional bakers deserve a little convenience. Let's get baking!
Ingredients for all in one cake
One bowl, three layers—this cake recipe simplifies everything without sacrificing restaurant-quality results.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 3 cups | Sifted for light texture |
| Granulated Sugar 🍚 | 2 cups | White or light brown |
| Unsalted Butter 🧈 | 1 ½ cups | Room temperature, full-fat |
| Large Eggs 🥚 | 4 whole | Room temperature preferred |
| Vanilla Extract 🌿 | 2 tsp | Pure, high-quality extract |
| Baking Powder 🧂 | 2 tsp | Diamond Crystal preferred |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Milk 🥛 | 1 cup | Room temperature, any fat |
| Heavy Whipping Cream 🥛 | 1 cup | Full-fat for best results |
| Cream Cheese 🧀 | 8 oz | Room temperature, full-fat |
| Powdered Sugar 🍚 | 3 cups | Sifted for smooth frosting |
| Cornstarch 🌾 | 2 tbsp | For custard stability |
| Large Egg Yolks 🥚 | 4 whole | Separated from whites |
| Milk 🥛 | 1 ½ cups | For custard mixture |
| Granulated Sugar 🍚 | ½ cup | For custard sweetness |
The flour is your foundation here—King Arthur or Gold Medal are my go-tos for that perfect crumb. Butter? Plugrá or Land O'Lakes work perfectly, but never skip the room-temperature step—it's non-negotiable for a tender crumb. Eggs should be at room temp too, so pull them out 30 minutes before baking. For the vanilla, Nielsen-Massey is my splurge pick, but any pure extract works. The baking powder? Diamond Crystal is the secret weapon—it's lighter than other brands, so your cake won't be dense. Pro tip: measure your dry ingredients by weight if you can—1 cup flour actually weighs 4.5 oz, not 8 oz.
No heavy cream? Whipped coconut cream works in a pinch, though the texture won't be identical. Cream cheese substitutions? Philadelphia brand is the gold standard, but Wegmans or Kroger own-brand are solid budget picks. For the custard, if you're out of cornstarch, arrowroot powder at the same amount does the trick. The powdered sugar for frosting? Confectioners' sugar from Domino or Sugar 'n Spice dissolves smoothly. Want extra flavor? Add 1 tsp lemon zest to the custard—trust me on this. And if you're worried about curdling, temper those egg yolks by whisking them with warm milk first.
This cake keeps beautifully—5 days in an airtight container at room temp, or 2 weeks refrigerated. The frosting? Store it in the fridge for 5 days, but bring it to room temp before using. For make-ahead magic, bake the cake layers and custard filling 1 day ahead, then assemble when ready. The flavors actually improve overnight. Freezing? The unfrosted cake layers freeze for 3 months—just thaw completely before frosting. And if you're serving a crowd, double the frosting recipe—it disappears faster than you'd think.

Step-by-step instructions for all-in-one cake recipe
Here's how to make this single-bowl wonder with perfect layers and foolproof technique.
Cream Butter and Sugars to Lighten the Mixture
In a large mixing bowl, combine the 1.5 cups unsalted butter and 2 cups granulated sugar. Using an electric mixer on medium speed, beat until the mixture is light and fluffy—this should take about 3-4 minutes. You'll know it's ready when the mixture nearly doubles in volume and turns pale, almost like whipped butter. This step incorporates air, which helps create that signature tender crumb.
I like to scrape down the sides of the bowl with a spatula every minute or so to ensure everything gets evenly incorporated. If your butter isn't quite room temperature, you might need to pulse the mixer for an extra minute. The key here is patience—rushing this step leads to dense cake layers instead of that light, airy texture we're after.
Add Eggs and Dry Ingredients Alternately
With the mixer running on low speed, add the 4 whole large eggs one at a time, mixing just until each is fully incorporated. After the eggs are combined, add 1 cup milk, 2 teaspoons vanilla extract, and mix again until smooth. This gradual addition prevents the mixture from curdling.
Now for the dry ingredients: In a separate bowl, whisk together the 3 cups all-purpose flour, 2 teaspoons baking powder, and ½ teaspoon salt. With the mixer on low speed, add about ⅓ of the flour mixture and mix just until combined. Repeat with the remaining flour mixture, ending with another ⅓. This alternating method ensures even distribution of ingredients without overmixing. Stop mixing as soon as the flour disappears—overmixing develops gluten and makes the cake tough.
Prepare the Cake Batter for Baking
Pour the batter into two 9-inch round cake pans lined with parchment paper (or greased and floured). I always tap the pans gently on the counter to remove any air bubbles that might have formed. Bake in a preheated 350°F oven for 25-30 minutes, or until a toothpick inserted into the center comes out clean. The cakes should spring back slightly when pressed gently in the center.
Here's the thing—every oven runs hot or cold, so start checking at the 20-minute mark. If the tops are browning too quickly, tent the pans with aluminum foil. The goal is perfectly domed, golden-brown layers with no raw centers. Let the cakes cool in the pans for 10 minutes before transferring to a wire rack to cool completely.
Make the Cream Cheese Filling
While the cakes cool, prepare the filling by beating the 8 oz cream cheese and 3 cups powdered sugar together in a separate bowl until smooth and creamy. Add the 4 whole large egg yolks one at a time, mixing well after each addition. Then, whisk in the 1.5 cups milk and ½ cup granulated sugar until fully combined. The mixture should be thick and smooth—almost like a custard.
For extra stability, mix in the 2 tablespoons cornstarch and cook the filling in a saucepan over medium heat, stirring constantly until it thickens enough to coat the back of a spoon. This step ensures the filling holds its shape between the cake layers. Let it cool completely before assembling.
Assemble and Frost the Cake
Once the cakes are completely cool, level the tops if needed. Place one cake layer on a serving plate and spread an even layer of the cream cheese filling on top. Replace with the second cake layer, then spread the remaining filling evenly over the top and sides. Finally, frost the entire cake with the 1 cup heavy whipping cream that you've whipped to stiff peaks.
To make the cream frosting, whip the 1 cup heavy whipping cream with 1 teaspoon vanilla extract until soft peaks form. Spread it over the cake while it's still slightly warm to help it adhere better. Chill the cake in the refrigerator for at least 1 hour before slicing—this lets the filling set and makes for cleaner cuts. Serve at room temperature for the best texture and flavor.
Pro Tips For Making All In One Cake
- Weigh Your Butter: I learned this the hard way—measuring butter by volume leads to dry, crumbly cakes. Use a kitchen scale for 225g (1 cup) of softened butter; packed cups compress differently, and that throws off the fat-to-flour ratio. No scale? Use the "scoop and level" method with a butter dish, but don’t press down.
- Cream Butter and Sugar Slowly: High heat makes sugar grainy, and rushing this step traps air unevenly. Let both butter and sugar sit at room temp for 30 minutes first, then mix on medium-low for 3–4 minutes until pale but not buttery. If your mixer sounds like a jet engine, you’re doing it wrong.
- Skip Overmixing the Batter: I was skeptical until I tried it—folding dry ingredients into wet in two additions (not three) keeps gluten from overdeveloping. After mixing flour, sugar, and eggs, stop when just combined; lumps are fine. Overmixing = dense, tough cake. (Your future self will thank you.)
- Bake Until Internal Temp Hits 205°F: Guessing doneness by look alone fails—this cake’s center stays gummy if pulled too soon. Insert an instant-read thermometer; 205°F guarantees a moist crumb without sticking. If the top browns too fast, tent with foil early. (Yes, even if you’re impatient like me.)
Make-ahead tips for this all in one cake
Bake Layers Ahead
Bake the cake layers 24 hours before assembling—they'll stay moist and flavorful when wrapped tightly in plastic wrap. Store them in an airtight container at room temperature. This is my secret for stress-free baking days when I'm hosting last-minute gatherings. The layers actually improve overnight as the flavors meld together. 💫
Prep Filling Early
Make the custard filling 1 day ahead and refrigerate it in an airtight container. Stir it gently before using to prevent separation. I often make this the night before to save time on baking day. The filling thickens slightly when chilled, making it easier to spread between layers without sogginess.
Frosting Prep
Whip the cream cheese frosting 4 hours before assembly and store it in the fridge. Bring it to room temperature before spreading—this helps it pipe smoothly and adhere perfectly. I like to make this first thing in the morning if I'm baking in the afternoon. The frosting stays stable for 3 days refrigerated, so it's perfect for make-ahead projects. ✨
Full Assembly Timeline
For maximum convenience, bake the layers and make the filling 1 day ahead, then assemble the cake 4 hours before serving. Chill the assembled cake in the fridge for 1 hour before slicing—this ensures clean cuts and prevents crumbs. I've used this timeline for birthday surprises, and it never fails to impress guests.
Storage Hacks
Store the fully assembled cake in an airtight container at room temperature for 3 days or refrigerate for 5 days. The frosting may soften slightly when chilled, so bring it to room temperature before serving. For longer storage, freeze the unfrosted cake layers (wrapped tightly) for 3 months—thaw completely before frosting. 🧊
Serving Prep
Slice the cake 1 hour before serving to give the filling time to set properly. Use a serrated knife dipped in hot water and wiped clean between slices for perfect cuts. Garnish with fresh berries or a sprinkle of powdered sugar right before serving. This final touch makes any cake look like it came from a bakery. 🍓

Frequently asked questions
Why does this recipe use only one bowl?
This clever method eliminates multiple mixing bowls and pans by combining the cake batter, filling, and frosting preparation in stages within the same container. The secret is baking the cake layers first, then using that same bowl for the custard filling while the cakes cool. It saves cleanup time while keeping everything perfectly organized.
Can I make this cake without an electric mixer?
For the butter and sugar step, use a sturdy wooden spoon and arm strength—it'll take about 5-7 minutes of vigorous mixing. After adding eggs and dry ingredients, switch to a spatula for folding. The custard filling can be whisked by hand in a saucepan, and the cream frosting requires just a whisk. Just be prepared for more elbow grease!
What if my cake layers sink in the middle?
This usually happens from overmixing or opening the oven too soon. First, check your baking powder—it should be fresh (6 months max). Second, bake for the full 25-30 minutes at 350°F without peeking. If it still sinks, try adding 1 tsp baking powder to your dry ingredients next time. The good news? Slight sinking can be disguised with extra filling and frosting!
How do I prevent the filling from leaking?
Undercooked cake layers are the #1 culprit. Always bake until a toothpick comes out clean, then let layers cool completely before assembling. For extra insurance, chill the assembled cake for 1 hour in the fridge before slicing. The cornstarch in the filling helps it set properly, but proper cooling is key. Pro tip: Use a serrated knife for clean slices!
Can I substitute the custard filling?
Yes! Try a raspberry jam layer (spread between cooled cake layers) or a chocolate ganache made with ½ cup melted chocolate + ½ cup heavy cream. For a lighter option, use whipped cream sweetened with 2 tbsp powdered sugar. Just ensure your substitute is at room temperature when assembling to prevent soggy layers.
