I was recently looking through my collection of Valentine’s Day cakes and I noticed something pretty significant. Nearly all of the cakes and desserts in that category serve enough for a small gathering! That’s great news if you’re throwing a Valentine’s (or Galentine’s) Day party, but not likely what you’d make to celebrate an evening with your significant other. So, I set out on a recipe testing journey in search of the most delicious, perfectly sized chocolate cake recipe for two. And guess what? I found it!

This chocolate cake recipe is essentially a super scaled down version of my favorite one-bowl chocolate cake recipe, so it’s incredibly easy to throw together. I thought it’d be so cute to make a mini layer cake, so the batter yields enough for three 4-inch cake layers (here are the tiny pans I use!). It will also make one 6-inch layer if you’d rather not build a tiny layer cake.
These mini chocolate cake layers are so moist and decadent with amazing chocolate flavor. The perfect texture comes partly from the oil and buttermilk added, partly from the hot liquid added at the end. That heat helps to bloom the cocoa powder and really incorporate the ingredients before the baking process.
Pro Tip: If you don’t have easy access to buttermilk you can easily make a DIY version by adding 1 Tablespoon of white vinegar, apple cider vinegar, or lemon juice into a measuring cup, then topping it with whole milk until it measures 1 Cup. Give the mixture a stir and let it sit for at least 15 minutes, which is how long it takes for the ingredients to chemically react.
I paired this chocolate cake with a halved version of my favorite chocolate buttercream and it’s just everything you could want in a chocolate cake. If you’d rather pair it with a different frosting flavor, here are some I recommend. Just be sure to half the recipe whichever you choose:
- Strawberry Buttercream
- Raspberry Buttercream
- Nutella Buttercream
- Coffee Buttercream
- Funfetti Buttercream
- Vanilla Buttercream
- Cream Cheese Buttercream
- Salted Caramel Buttercream
This small batch chocolate cake recipe also works great as a smash cake and is perfectly sized for any celebration where the guest list is 2-4 people. It could also be just the thing to lift someone else’s spirits or brighten your own day. That makes this cake extremely versatile – there are so many reasons to make it!
Small Batch Chocolate Cake
Equipment
- 3 4-inch cake pans OR
Ingredients
Small Batch Chocolate Cake
- 1/2 Cup (65g) all purpose flour
- 1/2 Cup (100g) granulated sugar
- 1/4 Cup (21g) unsweetened cocoa powder
- 1/4 tsp baking soda
- 1/4 tsp baking powder
- 1/8 tsp salt
- 1 large egg, room temperature
- 2 Tbsp vegetable oil
- 1/2 tsp pure vanilla extract
- 1/4 Cup (60ml) buttermilk, room temperature* DIY recipe in notes
- 1/4 Cup (60ml) hot coffee or hot water
Chocolate Frosting
- 1/2 Cup (113g) unsalted butter, room temperature
- 1 1/2 Cup (180g) powdered sugar
- 1/4 Cup (21g) unsweetened cocoa powder
- 1 1/2 Tbsp whole milk, room temperature
- 1 tsp pure vanilla extract
- pinch of salt, or to taste
Instructions
Make the Small Batch Chocolate Cake
- Preheat the oven to 350ºF and prepare three 4-inch or one 6-inch cake pan by spraying the sides with cooking spray and fitting the bottom(s) with a wax paper or parchment paper cake circle.
- Place all of the dry ingredients into a medium bowl and whisk them together. Add the egg, vegetable oil, vanilla, and buttermilk and whisk until fully combined. Add the hot coffee (or hot water) in a slow stream and whisk until fully combined and smooth. The batter will be very thin.
- Pour the batter into the prepared cake pan(s). If using 4-inch cake pans, bake for 18-22 minutes. If using a 6-inch cake pan bake for 24-28 minutes. The cake is done when it springs back to the touch and a toothpick inserted comes out clean. Cool completely before assembling and decorating.
Make the Chocolate Frosting
- In a stand mixer fitted with a paddle attachment, whip the butter on medium-high speed until creamy and light in color, 4-5 minutes.
- Scrape down the bowl and paddle, then add the powdered sugar, cocoa powder, milk, salt, and vanilla extract. Cover the mixer with a clean kitchen towel (to prevent ingredients flying out of the bowl), then turn the mixer to low speed and mix until all ingredients start to come together.
- Remove the kitchen towel, scrape down the bowl and paddle, then continue mixing on low speed until uniform and smooth, 2-3 minutes.
Assembly
- Once the chocolate cake is completely cooled, frost and decorate with the chocolate buttercream. To create the mini layer cake pictured, level the cake layers to your desired height. Add a swipe of chocolate buttercream onto a cardboard cake circle and place the first cake layer on top. Fill and stack the cake with chocolate buttercream, then crumb coat the cake with chocolate buttercream. Place the crumb coated cake in the refrigerator for at least 30 minutes to let the buttercream set firm.
- Use the remaining frosting to create a smooth buttercream finish and pipe a star border on top using Wilton Tip 4B. Decorate with sprinkles (I used Sprinkle Pop's "Hey Sugar" mix).
Notes
- The small batch chocolate cake layer(s) can be made ahead and stored at room temperature, covered tightly in plastic wrap, for up to two days. Alternatively, you can cover with plastic wrap and store in the freezer for up to two months before thawing to room temperature.
- The chocolate frosting can be made ahead and stored in an airtight container at room temperature for up to 1 day. Alternatively, you can store it in an airtight container in the refrigerator for up to two weeks. When you’re ready to use it, bring it back to room temperature and rewhip with your stand mixer to bring back to frosting consistency.

Hii may I know the final weight of the cake
Hi Hema! I’ve never weighed the final cake, so I’m not sure what the answer is!
Please advise if it was dutch processed cocoa used or the Hersheys Natural?, also could I use instant coffee granules with the hot water?, thanks
Hi Debbie! You can use either Dutch processed cocoa or Hershey’s Natural. I’ve used both and the results are the same. And yes, you can use instant coffee granules with the hot water. Enjoy!
Thanks for your valuable knowledge information because of useful updated for me, thank you for share this wonderful article.
I made three 4-inch deep dish cakes and they were excellent. The crumb was moist, slightly dense, but not heavy. The only minor change I made to the recipe was to use a mix of granulated and brown sugar and 3 tbsp vegetable oil. Instead of the buttercream frosting, I made an ermine frosting.
Yum, Sadie! That sounds amazing!!
Hi, how many cupcakes would this make?
Hi DJ! This recipe makes about 9 cupcakes. Fill the tins no more than 2/3 full and bake at 350F for 15-18 min. Enjoy!
How many batches do I need for 2 thick 8″ cakes?
Hi Nicole! For two thick 8″ cakes use this recipe: https://sugarandsparrow.com/chocolate-cake-recipe/
Big thanks for your amazing recipes! They’re a hit in my kitchen, and I’m already planning my next culinary masterpiece. Cheers from Germany!
Is it possible to make this cake gluten free with 1:1 flour ?
Thank you
Hi! Yes, it is. Enjoy!
Do you have small recipes for the other cakes? Is it basically halving the regular recipe?
Hi Kevin! I just posted a small batch vanilla cake and I’ll be posting a small batch funfetti cake soon! Here’s the vanilla version: https://sugarandsparrow.com/small-batch-vanilla-cake/ and for the funfetti, you’ll just use that vanilla cake recipe and fold in 2 Tbsp of rainbow sprinkles at the end. Any of my cakes can be made in this size by scaling the recipes by 1/3 (if the original recipe yields 3 6-inch layers) or 1/4 (if the original recipe yields 4 6-inch layers).
Awesome! Love a smaller cake! Do you have a comparable recipe for a small white/vanilla cake? Looking forward to trying this one, and (fingers crossed) a small white cake in the future, too! 🙂
Yay! I just finished recipe testing for a small batch vanilla cake and I’ll be putting it on the blog asap! Stay tuned 🙂
I made this recipe and it is downright excellent. Very moist and “chocolatey”. I love this recipe for gifts for friends and hostess gifts. Please continue and expeiment with more varieties!
Hiii are these 4×2 inch pans?? Or 4x3inch pans. Thanks! Beautiful cake!, all of your cakes are! I’m in the middle of making your strawberry cake rn! Can’t wait!
Hi Kayla! They’re 4 x 2 inch pans.
This is a delicious recipe as well as being a perfect little dessert! Your recipe for chocolate cake is excellent, moist and very chocolatey! I’m looking forward to trying more of your cakes, next one will be the marble cake. thank you!
This recipe is awesome!! I’ve made it several times and it turns out super every time. I bake it in my air fryer since it is so small and it works great.
Yest I made the chocolate version of your mini cake with your chocolate buttercream, (used the Buttermilk sub), SO GOOD! I made another today for a neighbor. I’m HOOKED on the adorable 4″ size. This cake is DIVINE, SO moist! And your buttercream is so soft and silky! Thank SO much! I’m thrilled to have come across your recipe(s) and look forward to trying the variations.
Hi Whitney! Just saw this small batch recipe and it’s perfect timing because I’m experimenting with this size cake today! I see that I would use 3 4″ pans. Can this recipe easily (successfully) be doubled to make 6 pans? Thank you! Love my new book, Anyone Can Cake!, btw!
