Ingredients for 5 inch chocolate cake
Precise measurements and quality ingredients create this perfectly moist 5-inch chocolate cake for two.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | ¾ cup | Softened to room temperature |
| Granulated Sugar 🍚 | 1 cup | Superfine preferred for smoother texture |
| Cocoa Powder 🍫 | ½ cup | High-quality Dutch-processed |
| All-Purpose Flour 🌾 | 1 ½ cups | Sifted for lightness |
| Buttermilk 🥛 | 1 cup | Room temperature preferred |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Vanilla Extract 🌿 | 2 tsp | Pure Madagascar preferred |
| Baking Powder 🧂 | 1 tsp | Aluminum-free preferred |
| Salt 🧂 | ¼ tsp | Fine sea salt |
| Powdered Sugar 🍚 | ¼ cup | For dusting |
| Dark Chocolate Chips 🍫 | ½ cup | 70% cacao minimum |
| Vegetable Oil 🫒 | ¼ cup | Light neutral flavor |
The cocoa powder and butter are non-negotiable for depth of flavor. Valrhona or Guittard cocoa powders deliver that rich, velvety chocolate taste—avoid the cheap grocery store brands that can taste bitter or chalky. For butter, Plugrá or Land O'Lakes unsalted are reliable choices, but if you're using European-style butter like President or Bregott, reduce the salt slightly since these often contain more salt. The buttermilk should be room temperature when measuring to ensure even mixing. If you don't have buttermilk, combine 1 cup milk with 1 tbsp vinegar or lemon juice, let it sit for 5 minutes, then proceed. For the chocolate chips, Ghirardelli or Lindt Excellence are excellent choices, but any 70% cacao or higher will work.
No buttermilk? Sour cream or plain yogurt at a 1:1 ratio works perfectly—just remember to reduce other liquids slightly to maintain moisture balance. Short on vanilla extract? Vanilla bean paste provides both flavor and texture, or scrape seeds from a vanilla bean for a more intense flavor. The baking powder should be fresh—if it's over a year old, replace it to avoid a dense cake. For the powdered sugar, Domino or C&H brands are reliable, but avoid confectioners' sugar that contains cornstarch if you want a finer dust. The vegetable oil adds moisture without altering the chocolate flavor—Crisco or any neutral-tasting oil will work, but avoid strongly flavored oils like coconut.
Store the cake in an airtight container at room temperature for up to 3 days for best texture. For longer storage, wrap tightly in plastic wrap and refrigerate for up to 1 week, though it's best enjoyed fresh. The cake freezes beautifully—wrap each slice individually in plastic wrap, then place in a freezer bag for up to 3 months. To serve, let it come to room temperature for about 30 minutes before slicing for clean cuts. The dusting of powdered sugar should be done just before serving to prevent clumping. This cake is perfect for meal prep—bake one ahead and store slices individually for quick dessert solutions.
Why You'll Love This Recipe
- No-Fuss Mixing: I swear by the 3-bowl method here—cream butter and sugar first, then fold in the dry stuff just until combined. That buttermilk? It keeps the crumb tender without tasting soured, and the cocoa powder dissolves so smoothly you’ll forget it’s even there.
- Rich, Fudgy Core: The secret’s in the sugar-to-butter ratio—this isn’t your dry, cakey box mix. It’s got that deep, molten chocolate center that melts like a bite of homemade fudge, but still holds its shape. (Yes, even when sliced thin.)
- Weeknight or Party Star: Bake it for a quick dessert after dinner—it’s ready in under an hour. Or freeze the whole cake, then slice and serve at room temp for birthday celebrations. The buttermilk base actually improves overnight, so leftovers taste even better.
- Pantry Staples Only: Honestly, you’re not digging deep for obscure ingredients. Butter, sugar, flour, cocoa—stuff you already have. And since it’s a single-layer 5-inch cake, it’s half the cost of a bakery version but twice as good. My grocery budget thanks me every time.
Step-by-step instructions for 5-Inch chocolate cake
Here's the method for achieving perfectly moist layers with a rich chocolate flavor every time.
Prepare Your Mixing Tools and Ingredients
Begin by preheating your oven to 350°F. Grease a 5-inch round cake pan thoroughly with vegetable oil and line the bottom with parchment paper, pressing it gently against the sides to prevent sticking. I like to use a small offset spatula for this to ensure full coverage.
Sift together the 1.5 cups all-purpose flour, 1 teaspoon baking powder, and ¼ teaspoon salt into a medium bowl. Set aside—this dry mixture will be added last to maintain the cake's moisture. Measure out the ½ cup cocoa powder and the 1 cup granulated sugar separately for precise blending.
Cream Butter, Sugar, and Oil for Lightness
In a large mixing bowl, combine the ¾ cup softened unsalted butter, 1 cup granulated sugar, and ¼ cup vegetable oil. Using an electric mixer on medium-high speed, beat these ingredients together for 3-4 minutes until light and fluffy. You'll notice the mixture nearly doubles in volume and becomes pale in color—this incorporates air that creates tender layers.
If your butter isn't quite room temperature, stop mixing briefly to press it between your fingers. It should feel soft but not greasy—this ensures proper emulsification with the other ingredients. The texture should resemble whipped cream rather than a heavy paste.
Incorporate Wet and Dry Ingredients
Add the 2 whole large eggs, one at a time, mixing on low speed after each addition until fully incorporated. Then add the 2 teaspoons vanilla extract and mix for another 30 seconds. The mixture will appear slightly curdled at this stage, but that's normal.
Gradually add the sifted dry ingredients while mixing on low speed. Scrape down the sides of the bowl as needed to ensure even distribution. When about half the flour is incorporated, gently fold in the ½ cup dark chocolate chips by hand using a silicone spatula. This prevents overmixing which can lead to a dense cake.
Add Buttermilk for Moisture and Mix
Pour in the 1 cup buttermilk and mix on low speed until just combined. Be careful not to overmix—just until the batter is smooth and no flour streaks remain. The buttermilk adds moisture and tenderness to the cake. The batter should be thick but pourable, similar to heavy pudding.
Real talk: If your batter looks too thick, you can add 1-2 tablespoons of milk to achieve the proper consistency. Too thin? Add 1 tablespoon of flour. The ideal batter should coat the back of a spoon but still flow slowly when tilted.
Bake to Perfect Doneness
Pour the batter into your prepared cake pan and smooth the top with a spatula. Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out clean with just a few moist crumbs clinging to it. The cake should spring back slightly when gently pressed in the center.
I've found that baking times can vary slightly based on your oven. If the edges are browning too quickly, tent the pan with aluminum foil after 15 minutes to prevent overbrowning while the center finishes cooking. Let the cake cool in the pan for 10 minutes before transferring to a wire rack to cool completely.
Dust with Powdered Sugar for Finishing
Once completely cooled, dust the top of the cake with ¼ cup powdered sugar using a fine-mesh sieve. This adds a delicate sweetness and professional finish. For an extra touch, you can drizzle with melted chocolate or add fresh berries between layers if making a layered cake.
The final result should be a moist, rich chocolate cake with a tender crumb and perfect rise. Each slice should be dense enough to hold its shape but light enough to melt in your mouth. Store leftovers covered at room temperature for up to 3 days or refrigerate for up to 5 days.
Pro Tips For Making 5 Inch Chocolate Cake
- Melt Butter Slowly: I learned this the hard way—dumping cold butter into hot sugar makes your batter seize up like a stubborn child. Instead, melt the butter first (just until it’s liquid but not browned) and let it cool to room temp before mixing. Your batter will be smoother, and the cake won’t turn out greasy.
- Sift That Cocoa: Unsifted cocoa powder is the enemy of even texture—it clumps like a bad hair day. Sift it with the flour first, then whisk the dry ingredients together. This keeps the cake light and prevents those dreaded dense pockets.
- Don’t Overmix Wet Ingredients: I used to beat the butter-sugar mix until it looked like it could stand on its own—big mistake. Stop when it’s just combined, not fluffy. Overmixing adds air, which can cause cracks or a dry crumb. This cake is rich, not airy.
- Test Doneness with a Toothpick: Skip the "press the center" trick—it lies. Insert a toothpick into the middle of the cake; it should come out with moist crumbs, not wet batter. If it’s still sticky, bake another 2-3 minutes. Overbaking turns chocolate cake into a brick.

Classic Chocolate Ganache
This velvety chocolate ganache elevates your cake instantly. Melt ½ cup heavy cream with ½ cup chopped dark chocolate (70% cacao) in a heatproof bowl over simmering water. Stir until smooth, then let cool slightly before drizzling over the cake. For extra richness, fold in 1 tablespoon whipped cream before applying. 🍫
Whipped Cream Frosting
Whip 1 cup heavy whipping cream with 2 tablespoons powdered sugar and ½ teaspoon vanilla extract until stiff peaks form. Pipe or spread over the cooled cake for a light, airy finish. For a chocolate twist, mix 1 tablespoon cocoa powder into the sugar before whipping. Keep refrigerated until ready to use.
Salted Caramel Drizzle
Heat ½ cup granulated sugar in a saucepan until melted, then add ¼ cup heavy cream and simmer for 5 minutes. Stir in 2 tablespoons butter and ¼ teaspoon flaky sea salt. Cool slightly, then drizzle over the cake. The salt enhances the caramel's sweetness beautifully.
Berry Compote
Simmer 1 cup mixed berries (raspberries, strawberries, blueberries) with 1 tablespoon sugar and 1 teaspoon lemon juice for 10 minutes. Mash slightly, then strain to remove seeds. Spoon or drizzle over the cake for a fresh, fruity contrast. Works especially well with the chocolate ganache.
Espresso Glaze
Combine ½ cup powdered sugar, 2 tablespoons strong brewed coffee, and 1 teaspoon vanilla extract. Whisk until smooth, then drizzle over the cake. The espresso deepens the chocolate flavor and adds a sophisticated touch. Let set for 15 minutes before serving.
Peanut Butter Swirl
Mix ½ cup creamy peanut butter with ¼ cup melted butter and 1 tablespoon honey. Spread a thin layer on the cake, then swirl with a knife. Top with a dusting of powdered sugar for a nostalgic, peanut butter cup-inspired treat. Perfect for peanut butter lovers! 🥜

Frequently asked questions
Can I make this cake in a different pan size?
This recipe is specifically designed for a 5-inch round pan to create the perfect two-serving portion. For a 6-inch pan, reduce baking time by 2-3 minutes (about 22-25 minutes total). For a 4-inch pan, increase time to 30-35 minutes and check for doneness early. The key is maintaining the same batter depth—about 1.5 inches—for even baking.
Why did my cake crack on top?
Cracking often happens when the cake cools too quickly or if the oven temperature fluctuates. To prevent this, let the cake cool in the pan for 10 full minutes before removing, then transfer to a wire rack. Also ensure your oven is fully preheated and avoid opening the oven door during baking. If cracks appear, they're usually harmless—just cover with frosting or ganache!
Can I substitute buttermilk if I don't have any?
Mix 1 cup milk with 1 tablespoon vinegar or lemon juice, let sit for 5 minutes until thickened, then use as a 1:1 replacement. For extra richness, you could also use 1 cup plain yogurt or sour cream, though the texture will be slightly denser. The buttermilk's tanginess helps balance the sweetness and keeps the cake moist.
How do I make this cake gluten-free?
Replace the 1.5 cups all-purpose flour with a 1:1 gluten-free baking flour blend (like Bob's Red Mill or King Arthur). Add ½ teaspoon xanthan gum if your blend doesn't contain it. For best results, let the batter rest for 10 minutes before baking, as gluten-free batters can be thicker. You may need to reduce baking time by 2-3 minutes since gluten-free cakes often bake faster.
Can I bake this cake ahead of time?
Yes! Bake it up to 2 days in advance and store wrapped at room temperature. For longer storage (1 week), refrigerate tightly covered. To serve, let it sit at room temperature for 30 minutes before slicing. The flavor actually improves with time as the moisture redistributes. For best texture, avoid freezing the cake itself—freeze individual slices instead for up to 3 months.
