Ingredients for 5 inch chocolate cake
Six ingredients transform into the perfect 5-inch chocolate cake—moist, rich, and precisely proportioned.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | 1 cup | Softened to room temperature |
| Vegetable Oil 🫒 | ½ cup | Light neutral oil preferred |
| Granulated Sugar 🍚 | 2 cups | White or light brown |
| Unsweetened Cocoa Powder 🍫 | ¾ cup | Natural or Dutch-processed |
| All-Purpose Flour 🌾 | 2 cups | Sifted, spooned and leveled |
| Baking Soda 🧂 | 1 tsp | Pure baking soda |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Vanilla Extract 🌿 | 2 tsp | Pure Madagascar vanilla |
| Sour Cream 🥛 | ½ cup | Full-fat for best texture |
| Hot Water 💧 | ½ cup | Just boiled and cooled |
| Dark Chocolate Chips 🍫 | 1 ½ cups | 70% cocoa or higher |
| Buttercream Frosting 🧁 | 2 cups | Classic American buttercream |
The butter and oil combo is non-negotiable for that signature tender crumb—Crisco or vegetable oil works best for neutral flavor. European-style unsalted butter like Plugrá or President melts beautifully without overpowering. For cocoa powder, Valrhona or Ghirardelli deliver that deep, velvety flavor, but Hershey's Special Dark works in a pinch. The sour cream adds moisture and richness, so full-fat is essential—none of that low-fat nonsense. Pre-sift your flour to avoid dense pockets, and measure it accurately using the spoon-and-level method. Pro tip: Let your ingredients sit at room temperature for at least 2 hours before baking for even distribution.
No vegetable oil? Melted coconut oil works in a bind, though it adds a slight coconut aroma. Swap Dutch-processed cocoa for natural cocoa by adding an extra 1/2 tsp baking soda to balance acidity. Short on vanilla? Vanilla bean paste adds specks of flavor magic, or use 1 tsp vanilla bean seeds scraped from a pod. The chocolate chips can be swapped for chopped dark chocolate bars—just chop them yourself for better texture. For the frosting, Land O'Lakes cultured butter gives the best consistency, but any high-fat butter works. Need a shortcut? Boxed mix buttercream is fine, but homemade tastes worlds better.
Store the cake layers in an airtight container at room temperature for up to 2 days—they actually improve overnight. For longer storage, freeze the unfrosted layers wrapped in plastic for up to 3 months. The frosting keeps for 5 days in the fridge, so assemble your cake just before serving. To prevent drying, brush the top with a simple syrup (equal parts sugar and water, heated until dissolved) before frosting. This cake is worth the extra effort—every slice will be a showstopper.

- No Mixer Needed: I swear by this recipe because it’s literally a bowl-and-spoon job. Just melt the butter and oil together, stir in the sugar, then fold in the cocoa and flour—no electric beaters, no stress. The batter’s thick but not stubborn, so it slides into your pans like butter.
- Rich Without Overpowering: Here’s what sold me—the cocoa isn’t bitter or heavy. The butter and oil (yes, both!) keep it moist but not greasy, while the sugar balances the depth. It’s the kind of chocolate cake that makes you close your eyes and take a second bite before you even cut the first slice.
- Party or Pajamas: This recipe works for everything. Need a last-minute birthday cake? Double the batter, bake in two pans, and frost with whipped cream—done. Craving a midnight snack? One 5-inch pan is perfect for two slices and zero guilt. Honestly, I’ve served it at brunch, potlucks, and even as a “fancy” dessert for takeout leftovers.

Plus, those 5-inch pans? They’re the perfect size to freeze half for later—so you’re always covered, and your wallet stays happy.
Step-by-step instructions for 5-Inch chocolate cake
This method guarantees a perfectly moist crumb with that ideal 5-inch height every time—no guesswork!
Cream Butter, Sugar, and Oil for Maximum Moisture
In a stand mixer fitted with the paddle attachment, beat the 1 cup unsalted butter and 0.5 cup vegetable oil on medium speed for 30 seconds until smooth. This combination of fats creates a tender crumb that stays moist for days. Gradually add the 2 cups granulated sugar while mixing on medium-high speed for 3-4 minutes until the mixture is light, fluffy, and nearly doubles in volume.
Here's the thing—creaming properly incorporates air into the batter, which is what gives us that perfect rise and tender texture. You'll know you've done it right when the mixture looks pale and ribbony when you lift the paddle. If it seems too thick, don't worry; it'll come together perfectly with the dry ingredients.
Incorporate Cocoa, Dry Ingredients, and Sour Cream
Reduce the mixer speed to low and add the 0.75 cup unsweetened cocoa powder, mixing just until combined. In a separate bowl, whisk together the 2 cups all-purpose flour, 1 teaspoon baking soda, and 0.5 teaspoon salt. With the mixer on low speed, gradually add the dry ingredients to the wet mixture, alternating with the 0.5 cup sour cream in 6 additions. Start and end with flour.
This alternating method ensures even distribution of ingredients while keeping the batter light. The sour cream adds richness and helps create that perfect tender crumb. Mix just until the dry ingredients are incorporated—overmixing develops gluten and can make the cake tough. The batter should be thick but smooth.
Add Vanilla, Hot Water, and Chocolate Chips
Add the 2 teaspoons vanilla extract and 0.5 cup hot water to the batter, mixing on low speed until just combined. The hot water helps activate the baking soda for maximum lift. Fold in the 1.5 cups dark chocolate chips by hand using a silicone spatula—this prevents overmixing and ensures even distribution of chocolate throughout the cake.
This is where the magic happens—the hot water creates steam that helps the cake rise beautifully, while the chocolate chips add pockets of rich flavor. The batter will be thick but should flow slightly when you lift the spatula. If it looks too stiff, you can add 1-2 tablespoons of milk to help it flow more easily into your pans.
Bake for Perfect Height and Moisture
Preheat your oven to 350°F and grease two 5-inch round cake pans (or one 9-inch round pan if preferred). Divide the batter evenly between the pans and smooth the tops. Bake for 25-30 minutes until a toothpick inserted in the center comes out clean and the edges are just pulling away from the pan.
Here's the crucial part: don't overbake! The cake will continue cooking as it cools. For a 5-inch cake, you're looking for a height of about 2 inches when removed from the oven—this will give you that perfect final height of 3-4 inches after cooling. The center should be just set but still slightly springy to the touch.
Cool and Frost for Ultimate Decadence
Allow the cakes to cool in their pans for 10 minutes, then transfer to a wire rack to cool completely. Once fully cooled, level the tops if needed, then frost with the 2 cups buttercream frosting. The buttercream should be at room temperature for easy spreading and a smooth finish.
This cake is all about that perfect balance of moist crumb and rich chocolate flavor. The buttercream adds a creamy contrast that makes every bite unforgettable. For the best results, refrigerate the cake for 30 minutes before slicing to help the frosting set properly. Serve with a dollop of whipped cream or fresh berries for an extra special touch!
Pro Tips For Making 5 Inch Chocolate Cake
- Melt Butter Slowly: Heat your butter and oil together over medium-low—never high—until it’s just melted and smooth. I learned this the hard way after burning the first batch; cocoa powder reacts fast, and you’ll regret rushing it.
- Sift That Cocoa: Sift the cocoa powder twice before mixing—once into the dry ingredients, once into the wet. Unsifted cocoa clumps like a stubborn lump, and your cake will taste uneven. (Yes, it’s extra work, but trust me.)
- Don’t Overmix: Fold the flour mixture into the wet ingredients just until combined—no more. Overmixing turns your cake dense and tough, and you’ll end up with a brick instead of a fluffy crumb. Stop when there are a few streaks left.
- Grease the Pan Right: Use 1 tablespoon vegetable oil and line the pan with parchment—even for a 5-inch cake. Butter alone won’t stick enough, and your cake might tear when unmolding. (I’ve seen it happen.)
Storing and reheating this recipe
Room-Temp Storage
Store your fully assembled cake at room temperature in an airtight container for up to 2 days. The key is using a container with a tight-sealing lid to prevent moisture loss. I love using Pyrex glass containers with snap-on lids—they keep the cake fresh while letting me see the layers. Just make sure the frosting is fully set before sealing to avoid condensation. 💫
Fridge Preservation
For longer storage, refrigerate the unfrosted cake layers wrapped tightly in plastic wrap for up to 5 days. The frosting can be stored separately in an airtight container for 5 days too. When ready to assemble, bring the frosting to room temperature for 30 minutes before spreading—this prevents melting and gives you that perfect smooth finish. Always let the cake sit at room temperature for 15-20 minutes before serving to restore texture.
Freezing Unfrosted Layers
Freeze unfrosted cake layers for up to 3 months by wrapping them tightly in plastic wrap and then placing them in a freezer bag. Squeeze out all the air to prevent freezer burn. When ready to bake, thaw the layers in the fridge overnight. I find this works best for special occasions when I want to bake ahead of time. Just
Reheating Frosting
If your frosting has hardened in the fridge, gently warm it in 10-second bursts in the microwave. Stir after each burst until it reaches a smooth, spreadable consistency. For a more controlled approach, place the frosting bowl in a larger bowl of warm water for 5-10 minutes. Never microwave for too long—this can make the frosting grainy and lose its silky texture. A little patience here makes all the difference in presentation.
Reviving Dried Cake
If your cake loses moisture over time, brush the top with a simple syrup (equal parts sugar and water, heated until dissolved) before adding fresh frosting. This trick instantly plumps up the crumb and restores that perfect texture. For extra moisture, place a small bowl of water in the fridge near the cake overnight—this helps maintain humidity in the airtight container. A little moisture magic can turn a stale cake into a showstopper again!

Frequently asked questions
Can I bake this in a 9-inch pan instead of 5-inch pans? Yes, but you'll need to adjust the baking time. For a 9-inch round pan, bake at 350°F for 40-45 minutes instead of 25-30 minutes. The cake will be taller and wider, but the texture will remain the same. Just
Why does my chocolate cake sometimes crack on top?
Cracking usually happens when the cake bakes too quickly or the oven temperature fluctuates. To prevent this, make sure your oven is fully preheated and use an oven thermometer to confirm it's at 350°F. Also, avoid opening the oven door during the first 20 minutes of baking. For extra insurance, place a baking sheet on the rack below your cake pans to reflect heat evenly.
Can I substitute sour cream with something else?
You can use Greek yogurt (full-fat, plain) or buttermilk in a 1:1 ratio. For a dairy-free option, try unsweetened almond milk yogurt or coconut cream. The sour cream adds moisture and richness, so any substitute should be thick and slightly tangy. Just remember that the texture might be slightly different, but the flavor will still be delicious.
How do I make this cake gluten-free?
Replace the 2 cups all-purpose flour with a high-quality 1:1 gluten-free baking flour blend like Bob's Red Mill or King Arthur. You'll likely need to add 1/4 cup extra gluten-free flour to account for the difference in absorption. Also, add 1/2 teaspoon xanthan gum if your blend doesn't include it—this helps with structure. The rest of the recipe remains the same, but check for doneness 5 minutes earlier than recommended.
What's the best way to level the cake layers?
Use a serrated knife or a cake leveler for clean, even cuts. First, dip the knife in hot water and wipe it dry—this helps create a smoother cut. Place the cake on a stable surface and gently press down with even pressure. For extra precision, use a laser level or a straightedge to guide your cuts. Always level the cake after it's completely cooled to avoid crumbling.
