Real chocolate in cake
To get the best chocolate cake, I like to make it with real melted chocolate (70% semi-sweet)—not baking chocolate, just really good chocolate you’d happily eat on its own.
The higher cocoa percentage enhances the bold chocolate flavor while still containing enough sugar to prevent bitterness. Its smooth texture melts beautifully into the batter, creating a moist, fudgy crumb. This cake also includes unsweetened natural cocoa powder for an extra boost of rich chocolate flavor.
Chocolate Buttercream Frosting
I also like to use real melted chocolate in my chocolate buttercream frosting—it adds a deep, rich chocolate flavor. While you can use chocolate ganache, you’ll want a proper frosting if you plan to pipe decorations on top.
Buttermilk or whole milk
I prefer using whole milk in chocolate cake, as it keeps the flavor rich and pure without the tang that buttermilk can add. That said, buttermilk is a popular option and can usually be swapped 1:1 for regular milk in chocolate cake recipes if you enjoy a slightly tangier, more tender crumb.
Cake size
This recipe makes two thick 4-inch (10 cm) round mini cakes. You can also use two 6-inch cake pans—they won’t be as tall, but they’ll be just as perfect. If using larger pans, reduce the baking time slightly. I like using springform pans, which make removing the cakes effortless.
How to evenly divide cake batter between 2 cake pans
The easiest way to get even layers is by weighing the batter. First, place each empty pan on a kitchen scale and zero it out. Then, pour batter into each pan until they weigh the same. Even layers bake more consistently and stack beautifully, giving you a professional-looking cake every time.
Flat top cakes
Cakes often develop a domed top as they rise. Before frosting, shave off the dome to create a flat surface—and enjoy a little sweet treat while you’re at it! A flat top keeps the second layer even when stacking and makes piping the final frosting much easier.
Cake frosting tips
- Place pieces of parchment paper under the edges of the cake. This allows you to frost it on the surface you plan to serve it on without making a mess—simply pull the paper out afterward.
- Apply a crumb coat (a thin first layer of frosting) to set the surface, creating a firm, smooth base for the final layer. The crumb coat seals in loose crumbs and prevents them from mixing into the outer frosting. Chilling the cake after the crumb coat helps the butter or fat in the frosting firm up, making it easier to apply the final coat without smudging or dragging crumbs. Using an offset spatula will help you achieve a perfectly smooth surface.
Two-tone frosting
Just like with my Key Lime Cupcakes, I use two colors of vanilla buttercream frosting in a single piping bag to create a beautiful two-tone effect. To do this neatly, first place each color in its own piping bag. Then, insert them side by side into a larger decorating bag before piping onto the cake. You can use vanilla buttercream or cream cheese frosting for this technique.
Knowing when cakes are done
A cake is perfectly baked when it’s set and the top is not shiny. I should spring back when gently pressed in the center. A toothpick or skewer inserted into the middle should come out clean or with just a few moist crumbs—no wet batter. The edges will also begin to pull slightly away from the pan, and the cake should smell fragrant and baked, not doughy.
Keep in mind that baking time can vary depending on your oven and the color of your cake pans. Dark-colored pans retain heat more efficiently and tend to bake cakes faster, while lighter-colored pans reflect heat and may require a slightly longer baking time. Always cool fully on a wire rack before frosting.
Make ahead mini chocolate cake recipe
Make the chocolate cakes a day or two in advance. Once completely cooled, wrap them tightly in plastic wrap and refrigerate for up to three days or store at room temperature for up to two days. A frosted cake will stay fresh for three to four days.
High altitude cake baking
This cake stays moist and fudgy, making it perfect for high-altitude baking. The drier air and lower pressure at higher elevations often dry out cakes, but the rich moisture in this recipe prevents this from happening.
Chocolate cake hack
Not much of a baker? Take a shortcut and buy a box of cake mix. No one will know, just customize with homemade frosting.
Cake decoration
You can go with my multi-color frosting method featuring a heart, or try my Easy Chocolate Shards (pictured below).
How to Make A Chocolate Heart
Add a cute Valentine’s Day touch with a homemade chocolate heart! Simply pipe a thin line of melted chocolate onto parchment paper in the shape of a heart, then refrigerate until it hardens. For best results, use chocolate meant for eating rather than baking chocolate. For a precise shape, print a heart outline, place it under the parchment paper, and trace it with the melted chocolate.

Ingredients
For the cakes:
- 2 ounces (55 grams) 70% semi-sweet chocolate, chopped (see note)
For the cake:
- ½ cup (65 grams) all-purpose/plain flour
- ½ teaspoon baking powder
- ¼ teaspoon salt
- 2 ½ tablespoons unsweetened cocoa powder
- 4 tablespoons unsalted butter, room temperature
- ⅓ cup (66 grams) granulated sugar
- 2 large eggs, room temperature
- ¼ cup (60 ml) milk, warmed (see note)
For the chocolate frosting
- 1 cup (227 grams) unsalted butter, softened to room temperature
- 3 cups (360 grams) powdered sugar
- 2 ounces (55 grams) semi-sweet chocolate , melted and cooled
- ½ cup (74 grams) unsweetened cocoa powder
- A little room temperature milk
For the colored frosting
- 16 ounces (453 grams) store bought white frosting
- Natural red frosting color
Instructions
Prepare the pans:
- Position the oven rack in the center and preheat to 325°F / 165°C.
- Butter and grease 2 round 4-inch x 2-inch (10 cm x 6 cm) springform cake pans.
- Melt the chocolate: Place the 2 ounces of chocolate in a microwave-safe bowl. Microwave on high in 30-second increments, stirring in between, until melted.
- Make the cakesIn a mixing bowl, sift together the flour, baking powder, salt, and cocoa powder. Set aside.
- In a separate large bowl, beat the butter and sugar until light and fluffy (about 4–5 minutes). Add the eggs one at a time, beating well after each addition, then add the milk and mix.
- Tip: If the mixture looks curdled or separates, don’t worry—it just means the butter and sugar weren’t fully creamed.
- Fold in the sifted flour mixture and melted chocolate until smooth and well combined.
- Divide the batter evenly between the two pans. The easiest way to ensure even layers is by placing each pan on scales and adding the batter until they weigh the same.
- Bake for 40–50 minutes (depending on your oven) or until a toothpick inserted in the center comes out clean.
- Allow cakes to cool in the pans for 10 minutes, then transfer to a wire cooling rack and cool completely.
Chocolate Frosting:
- Cream the butter and powdered sugar with a hand or stand mixer until light and fluffy.
- Gradually mix in the melted chocolate and cocoa powder, scraping the sides of the bowl to incorporate. If the frosting is too thick, add a little milk. Set aside for 1 hour to firm up.
- Two-Tone Red Frosting:
Divide the frosting between two bowls. Add red food coloring to one bowl until you reach the desired shade.
Place both the red and white frosting into a single piping bag to create a swirl effect when piping. - Chocolate Heart:Fill a small piping bag or zip-top bag with melted chocolate and cut a tiny corner off. Pipe a heart onto parchment paper. Tip: For a precise shape, print a heart outline, place the parchment over it, and trace. Refrigerate the heart until hardened.
- Assemble the Cake:Use a large, sharp knife to flatten the tops of the cakes. Place one cake layer on a flat surface. Spread a thick layer of chocolate frosting on top, then add the second cake layer.Place small pieces of parchment under the cake edges to keep your surface clean. Apply a thin layer of chocolate frosting all over the cake (this is the crumb coat). To seal in loose crumbs. Refrigerate for 30 minutes.
- Apply a final layer of chocolate frosting, smoothing with an offset spatula. You may not use all the frosting—adjust thickness to your preference. Refrigerate for another 30 minutes. Pipe the red and white frosting on top in your preferred design. Carefully remove the chocolate heart from the parchment and place it on top.
Made this for our anniversary. It came together really well, battery tastes delicious. I did change it a little. Added 1tsp espresso powder and instead of a 1/4 cup of milk I did 1/8 and 1/8 cup of coffee. I love a chocolate coffee flavor. And I’ll be turning this into black forest cake.
I’m glad you enjoyed it. I’m guessing battery is auto-correct for batter 😆
I use this cake recipe for my at home bakery business and I can’t find anything better. I live in high altitude and for some reason the recipe just works perfectly! I wish I could convert the recipe to a vanilla batter recipe because it is that good. Any tips on how to do so would be greatly appreciated!
Thank you. This would be a great idea, I think I need to test this.
I made this yesterday and the cake tasted delicious although it was slightly dry. I have a brand new oven and baked at 25 degrees less than the recipe recommended. Not sure what I did wrong as I did not get a super moist cake
LOVE this flavor in the cake so much. Do you know the best way to convert this to make it a larger cake? Looking to make 3 layer 6 inch cake and I am unsure how to change the recipe, temperature, and cook time to best suit this recipe!
It is impossible to find a similar recipe that includes the chocolate into the batter!
I’m so glad you enjoy the cake. What I would do is double the recipe and this should yield enough batter to divide between 3, 6-inch cake pans (you may have a little left over). I would bake at the same temperature and same time, give or take a few minutes. After 25-30 minutes I would check using the toothpick method, if it comes out clean, they’re done. I hope this helps, please let me know how they turned out, enjoy! 😁
Yummy 😋
The cake turned out fine so far… I haven’t assembled it yet but I think that you may have left out a liquid ingredient in the frosting mix. (one cup of butter, three cups of icing sugar and the cocoa. )
After blending for a long time it was just powdery. I added 1/4 cup of milk to blend it together.
I have been baking for many years and this did seem odd not to have any liquid, it must have just been an accidental omission.
There is melted chocolate added also
This chocolate to die for, I love mini idea. YUMMMMMMMMMMMMM 🫣😩🤪😉😉😉
Thank you 🙂
I doubled the recipe and made 4 mini bundt cakes with chocolate frosting. I love this recipe. It’s my go-to chocolate cake recipe.
I love this idea, thank you for sharing.
Love how chocolatey this cake is. I used your Bailey’s frosting which was delicious.
The Baileys frosting is so good with the chocolate. I’m glad you enjoyed it.
So easy to make. I made this cake with my daughters and they got to eat it as a treat. Was a fun day activity for them, thank you.
Aww, this is so nice. Thank you for choosing my recipe.
I just read this recipe. That seems like an awful lot of butter for a 4″ cake. Those measurements are almost enough for a 2 layer 8″ round.
4 tablespoons (1/4 cup) of butter is not a lot of butter for a 4-inch cake that is this tall, when 8-9-inch layer cakes call for 1 1/2 to 2 cups.
Is it 4×2 or 4×3 inch pan ?
The pans I use are 4 x 2 h. Let me know if you have anymore questions.
Best chocolate cake ever had!
Everyone loved it. Making it in a bigger pan for fathers day now.
I’m so happy the cake was a hit and enjoy Father’s Day.
Sorry my name is Sally rominski and I have subscribed but don’t know how to make a comment after I have made it
I’d love to hear your feedback. Just leave your comment the same way you left this one.
Delicious cake. I think that using real chocolate helps the taste and texture. I didn’t get too fancy with the frosting.
Thank you, I’m happy you liked it.
Thank you for this recipe, its perfect to make for my first birthday by myself!
Awww, I’ll share the cake with you. Happy Birthday.
Really tasty! It was so moist and chocolate-y too. I baked it in two ceramic ramekins because I didn’t have a mini cake pan, and it turned out p good. Thank you for the recipe!
I’m so glad you liked it, thank you for stopping by with the great feedback.
This is just the recipe I’ve been looking for. I’m cooking for my fiancé for V-Day and this is the perfect dessert.
I’m so happy, I hope he loves it
Nice mini chocolate cake idea. Thanks for it!
a Special gift for this Valentine, this cake is just dreamy! Perfect for a romantic evening with my sweetie! Love the beautiful frosting, it looks so special!
This is exactly what I need. Perfect for hubby and I.
How cute is this cake? So pretty! I LOVE this idea of a cake for two. So romantic, and all that chocolate. Yummmmm.
Oh this is adorable! Perfect for Valentine’s Day – I can just imagine each having a fork and digging right in 🙂
I’m a huge fan of desserts for two, and it’s perfect for Valentine’s Day, and any day! It’s delicious and looks gorgeous as well.
My wife made this today, jsut the right size for the two of us and it is really tasty thanks
What a gorgeous and delicious treat for Valentine’s Day!
It looks good, I’ll definitely be trying the recipe. I think the butter measurement for the chocolate frosting must be wrong though…should it be 2 tablespoons of butter instead of two cups of butter?
Hi Jen, the recipe is correct. It is a buttecream frosting and butter is the main ingredient. It makes a lot of frosting for the inside of the cake and two coats on the outside. Thank you for your interest.
For me, I wouldn’t make such a buttery frosting. But…………. I did make the cake. One of the best I’ve ever made. Thank you!
I’m so glad you liked it Laura. You can add whipping cream next time to the frosting so it’s not so buttery.
What a gorgeous cake, I love mint and I love chocolate so a perfect combination in my eyes:-)
I will happily share an appetizer, and I don’t mind splitting an entrée … but ain’t nobody eating half my cake! Unless it’s actually made to share. I particularly like the dual piping effect.
This cake is just dreamy! Perfect for a romantic evening with my sweetie! Love the beautiful frosting, it looks so special!
Awww, this is gorgeous, Janette! How romantic – sharing it with your significant other!
Hopefully though it’s quite a big ‘mini’ chocolate cake because I’d be wanting quite a lot of it for myself!
Looks soooo pretty!!! Perfect date night dessert. I love how impeccable the piping is. Great work!
Or one! I don’t know if I’d want to share such a delicious looking cake;)
This mini cake for two is simply beautiful and perfect for an at-home valentines day celebration that I am planning! YUM
This little cake is so pretty! And I have DEFINITELY been there, where my husband orders a dessert and I end up eating most of it. This looks perfect for valentines day, or really any night when we want something sweet but don’t need a ton of leftovers sitting around tempting us!
That’s gorgeous! I don’t think I’d share it though, so it’d end up being a mini chocolate cake for one. 😉
