Intensely Rich Small Batch Chocolate Layer Cake
This post may contain affiliate links. See the Disclosure Policy.
I first made this cake several years ago when I was on a quest to make the perfect small batch chocolate cake (ok, I really just wanted a chocolate cake for dessert). The kind of chocolate cake perfectly sized for two. A cake with an ultra-moist crumb and deep chocolate flavor. This mini chocolate cake with two heavenly layers checks all those boxes.
This cake is so good you can go to it over and over for special occasions (hello Valentine’s Day), or just because. And it didn’t just satisfy my hankering for cake – it has inspired a whole family of chocolate cakes! I have a smaller version of this cake with my 6-inch single-layer chocolate cake, and I developed a holiday favorite with the peppermint mocha small batch layer cake.
After several rounds of rigorous testing (translation: 8 hours later with a sink full of dirty mixing bowls 🙂 ), I cracked the code on how to make a soft chocolate cake that truly tastes like chocolate. So, if you’re ready for a chocolate cake so indulgent it feels like an event, let’s dive in!
My Secret To Soft And Moist Chocolate Cake
- I use Dutch process cocoa for a deep chocolate flavor.
- Full-fat sour cream + oil makes the cake tender and moist for days.
One may think that baking in small batches would be easy, but I’m here to tell you I still go through several rounds of recipe testing to make sure it can be successfully replicated in your kitchen. And I spend more time on my small batch cake recipes than any other dessert.
Eggs are a factor, as are the types of leaveners and cocoa powder. And let’s not forget what it takes to make – and keep – a cake moist. Now, I will be the first to tell you that there is no right or wrong way – as long as the result is delicious. But what I will tell you is my way to make a soft and moist chocolate cake.
Tips For Making A Small Chocolate Layer Cake

Sift the dry ingredients – especially the cocoa powder – if they are lumpy.

Use hot coffee to enhance the cocoa flavor. And I recommend coffee you like to drink. And if you don’t drink coffee, use hot water!

Don’t overmix the cake batter. Mix until no flour streaks remain, but it is ok if the batter is lumpy. Too much mixing will yield a tough and dense cake.

If the cakes have a domed top, trim off the top with a serrated knife to make the layers level. Not mandatory, but it makes the presentation pretty.
Decorating Ideas


Now that we have our favorite chocolate cake recipe, the sky is the limit on how you can decorate it. Like, you can get super creative and make the cake into small marshmallow heart cakes for Valentine’s Day! Or, keep it simple, like I did for this cutie’s photoshoot.
For this recipe, I include caramel sauce, which works great as a drizzle on the cake. Or, you can always use store-bought caramel to keep it simple (I’ve done it, so no judgment here).
Along with easy chocolate whipped cream. Heavy cream and melted chocolate is all you need to make a lighter alternative to buttercream.

I’d love to hear if you made the cake for a special celebration. Or, if you’re like me, just because you wanted cake. 🙂 Let me know in the comments below!

INSTRUCTIONS
Small Chocolate Layer Cake
- Preheat the oven to 350F degrees and adjust the oven rack to the middle position. Grease the pans and line the bottoms with a piece of parchment paper cut to fit.
- In a medium mixing bowl, whisk together the sugar and oil. Add the sour cream, egg, and vanilla extract. Whisk until smooth and creamy.1 cup granulated sugar, 1/4 cup canola oil, 1/2 cup full fat sour cream, room temperature, 1 large egg, 2 teaspoons vanilla extract
- In another medium mixing bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt. Tip – Set a fine mesh strainer over the bowl to sift the dry ingredients – especially the cocoa powder – if they are lumpy.1 cup all-purpose flour, 1/2 cup unsweetened cocoa powder, Dutch process, 3/4 teaspoon baking powder, 1/2 teaspoon baking soda, 1/2 teaspoon salt
- Sprinkle half of the dry ingredients over the wet ingredients and whisk until just combined. Add the remainder of the dry ingredients, along with the hot coffee, and whisk just until no dry streaks remain.1/2 cup medium brew coffee, very hot
- Pour the batter into the prepared cake pans and bake for 22 to 26 minutes, or until the cake is springy to the touch and a toothpick inserted in the middle comes out clean.
- Cool the cakes in the pan set on a wire cooling rack for 10 minutes. Then, invert the cakes onto the rack to cool completely before assembling.
- While the cakes are baking and cooling – Make homemade maple syrup caramel sauce, or use store-bought for the drizzle on the cake.optional caramel drizzle
Chocolate Whipped Cream
- In a microwave-safe bowl, melt the chocolate chips – stirring every 30 seconds – until the chocolate is smooth. Set aside to cool.1/2 cup chocolate chips, any kind
- In a medium mixing bowl, use a hand mixer to whip the heavy cream to soft peaks. Add 1/4 of the whipped cream to the melted and cooled chocolate and mix until well incorporated – this gets the chocolate to the right consistency to mix with the whipped cream. Add the chocolate mixture to the remaining whipped cream and gently fold with a rubber spatula until fully incorporated.1 cup heavy cream
- Assemble the cake – If the cakes domed too much, level out the tops with a serrated knife. Drizzle each top with caramel sauce and dollop generous amounts between the layers and on top.
RECIPE NOTES
- Serving Size – This is a small batch recipe that can be doubled and made into an 8-inch layer cake. Increase the bake time by 1 to 2 minutes. As written, the cake can also be made into a single-layer 8-inch cake.
- Cocoa Powder – I prefer Dutch cocoa because I like the less-acidic, deep flavor. However, you can swap in natural cocoa powder with no recipe modifications.
- Coffee – Use coffee you like to drink. Be careful with coffee that is too strong, as it can overpower the cocoa flavor.
- Chocolate Whipped Cream – If you use unsweetened or bittersweet chocolate chips, you will want to add powdered sugar while whipping the cream – about 3 to 4 tablespoons to sweeten to taste.
- Caramel Sauce – This is optional and store-bought will work just fine.
- Storage – The assembled can should be covered and can sit at room temperature for 6 to 8 hours. Beyond that, I recommend refrigerating it because of the whipped frosting.
- Freezing – Unfrosted/unassembled cakes can be wrapped in plastic wrap, placed in a freezer bag, and frozen for up to 3 months. Thaw in the refrigerator.
