Ingredients for baker's semi sweet chocolate cake
Precise ratios and quality ingredients create this restaurant-worthy semi-sweet chocolate cake with velvety frosting.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for light texture |
| Granulated Sugar 🍚 | 2 cups | Superfine preferred for smoothness |
| Unsalted Butter 🧈 | 1 ½ cups | Room temperature, cubed |
| Semi-Sweet Chocolate Chips 🍫 | 1 ½ cups | High-quality baking chocolate |
| Large Eggs 🥚 | 2 whole | Room temperature, separated |
| Baking Powder 🧂 | 2 tsp | Diamond Crystal preferred |
| Cocoa Powder 🍫 | ½ cup | Dutch-processed for richness |
| Vanilla Extract 🌿 | 2 tsp | Pure Madagascar bourbon |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Milk 🥛 | ½ cup | Whole milk for moisture |
| Powdered Sugar 🍚 | 3 cups | For frosting, sifted |
| Unsalted Butter 🧈 | 1 cup | Room temperature, extra for frosting |
| Heavy Cream 🥛 | ½ cup | Cold for whipped frosting |
The chocolate matters most here—Ghirardelli or Valrhona semi-sweet baking chips deliver the deepest flavor without bitterness. For the butter, Plugrá or Land O'Lakes unsalted are reliable choices, but always use room-temperature to ensure proper emulsification. The cocoa powder should be Dutch-processed (like Hershey's Special Dark) for a smoother finish. Sift both the flour and cocoa before measuring to prevent dense layers. Vanilla extract is non-negotiable—Madagascar bourbon has the most complex profile, but any pure extract works in a pinch.
No superfine sugar? Pulse regular granulated sugar in a food processor for 30 seconds—it'll work just as well. Out of baking powder? Baking soda plus cream of tartar (1 tsp each) substitutes perfectly. For a richer frosting, replace half the milk with heavy cream. The chocolate chips can be swapped for chopped chocolate bars (70% cacao), but measure by weight for consistency. If your frosting curdles, whisk in 1 tsp lemon juice to stabilize it. For a gluten-free version, use a 1:1 flour blend like Bob's Red Mill.
Store cake layers wrapped in plastic at room temperature for up to 3 days—they actually improve overnight as flavors meld. The frosting keeps for 5 days refrigerated, but add a thin layer of plastic wrap directly to the surface to prevent drying. For make-ahead convenience, bake layers 2 days ahead and freeze fully frosted cakes for up to 3 months. Bring to room temperature before serving. The frosting can be made 1 day ahead—just whip it again briefly before using to restore volume.

Step-by-step instructions for baker's semi-sweet chocolate cake
Master this classic technique for layers that stay moist and a frosting that melts perfectly.
👨🍳 Step 1: Prepare the Cake Batter with Precision
Preheat your oven to 350°F and grease two 9-inch round cake pans, lining the bottoms with parchment paper. In a medium bowl, whisk together the 2.5 cups all-purpose flour, 0.5 cup cocoa powder, 2 tsp baking powder, and 0.5 tsp salt. Sift the dry ingredients directly into the bowl to eliminate lumps—this creates a lighter texture.
In a separate large bowl, cream the 1.5 cups unsalted butter and 2 cups granulated sugar together using an electric mixer on medium speed for 3-4 minutes until light and fluffy. The mixture should nearly triple in volume and become pale in color. This step is critical for achieving that signature tender crumb—don't rush it.
Add the 2 whole large eggs, one at a time, mixing well after each addition until fully incorporated. The batter should be thick and ribbon-like when you lift the beaters. Stir in the 2 tsp vanilla extract and 0.5 cup milk until just combined. Finally, gradually fold in the 1.5 cups semi-sweet chocolate chips and the sifted dry ingredients using a spatula, mixing just until no dry spots remain. Overmixing develops gluten, which can make the cake dense.
🍳 Step 2: Bake to Perfect Doneness
Divide the batter evenly between the prepared cake pans, smoothing the tops with a spatula. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean with just a few moist crumbs clinging to it. The edges should be set but the tops still slightly springy to the touch—this ensures a tender crumb.
I know it's tempting to overbake for that "fully done" look, but chocolate cakes are more forgiving when slightly underdone. If the tops brown too quickly, tent the pans with aluminum foil after 20 minutes to prevent over-browning while maintaining even cooking.
Remove the cakes from the oven and let them cool in their pans for 10 minutes. Then transfer them to a wire rack to cool completely. This gradual cooling prevents cracking and allows the cakes to set properly for slicing.
🥘 Step 3: Create the Ultimate Buttery Chocolate Frosting
While the cakes cool, prepare the frosting by beating the 1 cup unsalted butter and 3 cups powdered sugar together in a large bowl using an electric mixer on medium speed until smooth and creamy. The butter should be at room temperature for this to work properly—press a finger into it; if it leaves an indentation, it's ready.
In a separate small bowl, whip the 0.5 cup heavy cream with a hand mixer until soft peaks form. Gently fold the whipped cream into the butter-sugar mixture, mixing just until combined. This adds lightness without compromising the frosting's rich flavor. Taste and adjust sweetness if needed—sometimes the cocoa in the cake makes the frosting seem slightly less sweet than intended.
Spread the frosting evenly between the two cake layers, creating a smooth base. Then cover the entire cake with the remaining frosting, using a spatula to create clean sides. For extra flair, pipe decorative swirls or drizzle melted chocolate around the edges. Chill the cake in the refrigerator for 30 minutes before slicing to allow the frosting to set slightly.
⏰ Step 4: Serve with Confidence
Slice the cake into 8 equal portions using a sharp serrated knife. For clean cuts, dip the knife in hot water and wipe it dry between slices. The perfect semi-sweet chocolate cake should have moist, fudgy layers that hold together beautifully and a frosting that's rich but not overly sweet.
Serve at room temperature for the best texture contrast—the warm cake against the cool frosting creates an irresistible experience. Store any leftovers covered at room temperature for up to 3 days or refrigerated for up to 1 week. The frosting may soften slightly when brought back to room temperature, so plan to serve within 2 hours of removing from the fridge.
Pro Tips For Making Baker'S Semi Sweet Chocolate Cake
- MELT THE CHOCOLATE RIGHT: Mix the melted butter and chocolate chips together first, then whisk in the sugar—this keeps the batter smoother and prevents clumps. I used to add the chocolate last, and the result was always streaky and uneven.
- WEIGH YOUR FLOUR: Scooping flour from the bag packs it down, adding extra volume and making your cake dense. Use a kitchen scale for accuracy—this recipe is unforgiving if you eyeball it.
- DON’T OVERMIX THE BATTER: Stop mixing as soon as the flour disappears; overworking it develops gluten, which turns your cake into a tough brick. Two minutes max after adding the dry ingredients—yes, even if it looks lumpy.
- CHILL THE BATTER: Let the batter sit for 10 minutes before baking—this helps the chocolate sink evenly and prevents a domed top. I know, it’s tempting to rush, but this small pause makes all the difference in texture.
Essential equipment for great baker's semi sweet chocolate cake
Mixing Essentials
Your stand mixer is the MVP for this recipe—I swear by my KitchenAid Artisan Series with the paddle attachment for creaming butter and sugar. The paddle creates a smoother texture than whisk attachments, especially for dense batters like this. If you don’t have one, a hand mixer works, but expect to work slightly harder for that perfect ribbon stage. 💛
For measuring, invest in a digital kitchen scale ($20-$30) to weigh your flour and sugar—it’s far more accurate than volume measurements. I use the OXO Good Grips scale, which has a tare function for easy ingredient additions. The difference in texture between weighed and scooped flour is night and day—trust me, your cake will thank you.
Baking Tools
Two 9-inch round cake pans are non-negotiable—Wilton Perfect Results pans are my go-to for even baking and easy release. Line the bottoms with parchment paper circles (I cut my own from a sheet) to prevent sticking and ensure clean slices. Grease the pans with butter or baking spray—never nonstick spray, as it can leave a residue that affects flavor.
A toothpick or cake tester is essential for checking doneness. Insert it into the center of the cake—if it comes out with a few moist crumbs but no wet batter, you’re golden. For even baking, place your pans on the middle rack of your oven, rotating them halfway through if your oven runs hot or cold spots.
Frosting Gear
The offset spatula is your frosting best friend—Michael Baker’s 6-inch is my top pick for smooth, professional-looking sides. For piping decorative swirls, a Wilton 1M piping tip with a pastry bag (or even a plastic bag with a corner snipped off) works perfectly. If you’re skipping decoration, just use the spatula to create clean, even layers.
For temperature control, a candy thermometer ($10-$15) helps monitor butter and cream temperatures—critical for the frosting’s stability. I keep my Thermoworks Thermapen handy for all baking tasks. Chill your cake on a wire rack in the fridge for 30 minutes before slicing to set the frosting properly without melting it.
Budget-Friendly Swaps
No stand mixer? A wooden spoon and strong arm work for creaming butter and sugar—just be ready to exert some elbow grease. For measuring, a medicine cup or standard measuring cups suffice, though accuracy drops slightly. The OXO Good Grips measuring cups are a splurge worth it for their clear markings and pour spouts.
Skip the piping bag? Use a zip-top bag with a corner snipped off for quick decorations. A spatula alone can still create beautiful, even layers if you take your time. For scaling, even a basic analog scale (like the Escali Primo) improves consistency over volume measurements. The key is patience—take your time with each step, and your cake will shine. ✨

Frequently asked questions
Can I substitute semi-sweet chocolate chips with dark chocolate bars?
Yes, but adjust the measurements carefully! Use 70% cacao dark chocolate bars instead of chips, and melt them first before mixing into the batter. For every 1.5 cups of chips called for, use 6 ounces (170g) of chopped dark chocolate. Dark chocolate has less sugar, so you may want to add 1-2 tablespoons extra sugar to balance the flavor. Never use milk chocolate—it'll make the cake too sweet.
Why does my chocolate cake turn out dry or crumbly?
Most likely, you overbaked it or didn't use enough fat/moisture. Chocolate cakes should be checked at 30 minutes—they're done when a toothpick comes out with just a few moist crumbs. For extra moisture, add 2 tablespoons sour cream or yogurt to the batter. Also ensure your butter and eggs are room temperature, and don't overmix the batter after adding dry ingredients.
Can I make this cake in a single layer instead of two?
Use a 9-inch springform pan or 10-inch round pan and reduce the batter by 25% (about 1.875 cups total). Bake for 40-45 minutes at 350°F instead of 30-35 minutes. The frosting quantity stays the same—just spread it evenly over the top layer. Single-layer cakes are perfect for smaller gatherings or when you want a dramatic presentation.
How do I make this cake gluten-free?
Replace the all-purpose flour with a 1:1 gluten-free baking flour blend like Bob's Red Mill or King Arthur. Add 1 teaspoon xanthan gum to the dry ingredients to improve texture. For the cocoa powder, use a gluten-free brand. The rest of the recipe remains unchanged. Note that gluten-free cakes may be slightly denser—bake for 5-10 minutes longer than specified to ensure doneness.
Can I make the frosting ahead of time?
Yes! Prepare the frosting 1 day ahead and store it in an airtight container in the fridge. Before using, let it sit at room temperature for 30-60 minutes to soften, then whip it briefly with a hand mixer to restore volume. For long-term storage, freeze the frosting for up to 1 month. Thaw it in the fridge overnight before whipping back to smooth perfection.
