Ingredients for betty crocker super moist chocolate cake
Twelve ingredients, one legendary cake. Here's what transforms boxed cake dreams into homemade reality.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | 1 ½ cups | Melted and cooled slightly |
| Granulated Sugar 🍚 | 2 ½ cups | White or light brown |
| Dark Brown Sugar 🍚 | ½ cup | Packed firmly |
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted, spooned and leveled |
| Cocoa Powder 🍫 | ¾ cup | Natural or Dutch-processed |
| Baking Soda 🧂 | 1 ½ tsp | Pure, not baking powder |
| Instant Coffee Powder ☕ | 2 tsp | Enhances chocolate depth |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Buttermilk 🥛 | 1 ½ cups | Room temperature |
| Vanilla Extract 🌸 | 2 tsp | Pure, high-quality |
| Vegetable Oil 🫒 | ½ cup | Or melted butter |
| Hot Water 💧 | ½ cup | For coffee powder |
| Powdered Sugar 🍚 | 4 cups | For buttercream |
| Heavy Whipping Cream 🥛 | 1 ½ cups | Cold, full-fat |
| Vanilla Bean Paste 🌸 | 1 tbsp | Or 1 tsp extract |
The cocoa powder is non-negotiable—Hershey's Special Dark or Valrhona for that restaurant-quality depth. Grab it from the baking aisle, not the chocolate bar section. For the butter, Land O'Lakes unsalted or Plugrá melts beautifully without buttering up the flavor. The buttermilk? Make your own by mixing 1.5 tbsp vinegar with 1.5 cups milk if you're out—it's a game-changer for moisture. And that instant coffee? Starbucks Via or Folgers works perfectly. Pro tip: Measure your flour by spooning it into the cup and leveling—don't scoop directly from the bag.
No buttermilk? Substitute with 1.5 cups milk + 1.5 tbsp lemon juice—same tang, same magic. Running low on cocoa? Melted dark chocolate (6 oz) + 1 tbsp cocoa powder replaces 3/4 cup cocoa. The vanilla bean paste? Trader Joe's has the best budget option, but any quality paste will do. For the buttercream, Land O'Lakes heavy cream whips up perfectly—just make sure it's cold. No powdered sugar? Blend 3 cups granulated sugar in a food processor for a quick fix. And if you're feeling fancy, add 1 tbsp rum extract to the buttercream for a boozy twist.
This cake keeps 5-7 days wrapped at room temperature, but honestly? It's best the first 2 days. For longer storage, slice and freeze portions between parchment paper for up to 3 months. The buttercream? 3-4 days max in the fridge—it separates if left too long. I always make extra frosting because it disappears faster than the cake. And if you're prepping ahead, bake the cake layers 1 day early—they actually improve overnight. Just store them in an airtight container with parchment between layers.
Why You'll Love This Recipe
- No Mixer Needed: I swear by this recipe because it’s one of those rare cakes where you don’t have to whip eggs or cream butter for hours. Just melt the butter, mix the sugars and cocoa into that rich, velvety brown paste—it’s basically foolproof. My lazy Sundays just got a whole lot sweeter.
- Dark Chocolate Magic: That combo of granulated and dark brown sugar? It’s what makes this cake taste like a bakery secret. The brown sugar caramelizes just enough to give it this deep, molasses-kissed flavor, while the cocoa powder delivers that pure, intense chocolate punch. Honestly, it’s the kind of cake that makes you question why you ever bought boxed mix.
- Birthday to Brunch: This cake is my go-to for celebrations and lazy mornings. Frost it with whipped cream for a birthday, crumble it over yogurt for breakfast, or slice it into squares for a potluck—it’s adaptable without trying too hard. (Yes, even on a Tuesday night when you’re craving something indulgent but don’t want to bake from scratch.)
- Leftovers That Last: Between us, this cake stays moist for days—like, I’ve had slices on day three and they’re still better than most store-bought. Plus, the ingredients are pantry staples, so it’s a budget win. Make a double batch, freeze half, and thank me later when you’re reheating a slice straight from the fridge.
Step-by-step instructions for Betty Crocker's super moist chocolate cake
Here's how to create layers of velvety chocolate perfection with fudgy swirls—no dry crumbs in sight.
👨🍳 Step 1: Prepare the Chocolate Batter
Preheat your oven to 350°F and grease two 9-inch round pans with the 1.5 cups unsalted butter (melted and cooled slightly). Line the bottoms with parchment paper for easy removal. In a large mixing bowl, combine the 2.5 cups granulated sugar, 0.5 cup dark brown sugar, 1.5 cups buttermilk, 0.5 cup vegetable oil, and 2 tsp vanilla extract. Whisk until the sugars dissolve completely—this prevents graininess in your cake.
In a separate bowl, sift together the 2.5 cups all-purpose flour, 0.75 cup cocoa powder, 1.5 tsp baking soda, 2 tsp instant coffee powder, and 0.5 tsp salt. The coffee powder might seem unusual, but it deepens the chocolate flavor without adding bitterness. Gradually add the dry ingredients to the wet mixture, whisking just until combined—overmixing develops gluten and makes the cake tough.
🍳 Step 2: Create the Fudgy Swirls
Here's where the magic happens: divide the batter evenly between two bowls. To one bowl, add 0.5 cup hot water and mix well. This creates a thinner, fudgier batter that will create those signature swirls. The other bowl remains as the regular chocolate batter. For each pan, pour half of the regular batter, spreading it evenly with a spatula.
Drop spoonfuls of the fudgy batter (with hot water) onto the regular batter in each pan, spacing them about 2 inches apart. Using a knife, gently swirl the fudgy batter into the regular batter, creating marbled patterns. Tap the pans gently on the counter to release any air bubbles—this ensures smooth layers when baked. Don't over-swirl or the patterns will break during baking.
🔥 Step 3: Bake to Perfect Doneness
Bake the cakes for 30-35 minutes until a toothpick inserted into the center comes out with a few moist crumbs (not wet batter). The edges should be set, but the center should still have a slight bounce—this ensures maximum moisture. Rotate the pans halfway through baking for even heat distribution. I know it's tempting to check early, but resist—underbaking leads to dense, gummy centers.
Let the cakes cool in the pans for 10 minutes before transferring to a wire rack to cool completely. This gradual cooling prevents cracking. While they cool, make the buttercream by beating the 4 cups powdered sugar, 1.5 cups heavy whipping cream, and 1 tbsp vanilla bean paste until light and fluffy. The buttercream should be thick enough to hold peaks but still spreadable—if it's too stiff, add 1 tsp hot water to loosen it.
🥘 Step 4: Assemble the Cake Layers
Once completely cool, level the tops of the cakes if needed. Place the first layer on a cake stand or plate and spread a generous layer of buttercream on top. The cake should be at room temperature for easier slicing—this prevents crumbling. Place the second layer on top and repeat with another layer of buttercream. For extra decadence, spread a thin layer of buttercream on the outside of the cake before adding the final layer.
Chill the assembled cake in the refrigerator for 30 minutes before serving. This allows the layers to set and makes slicing cleaner. The final result should be moist, rich chocolate layers with fudgy swirls peeking through—no dryness here! Serve with whipped cream or fresh berries for a perfect dessert that lives up to its "super moist" reputation.
Pro Tips For Making Betty Crocker Super Moist Chocolate Cake
- Melt Butter Slowly: The recipe calls for melted butter, but don’t just dump it in hot—warm it gently in the microwave in 20-second bursts, stirring between each. I learned this the hard way when I microwaved it all at once and ended up with greasy, separated batter that wouldn’t hold together.
- Sift the Cocoa: Skip the measuring spoon for cocoa powder—it packs differently. Lightly sift it into the dry ingredients to avoid clumps, especially if your powder is on the finer side. This keeps the texture even and prevents dense pockets in your cake.
- Don’t Overmix: Once you add the eggs and buttermilk, mix just until combined—maybe 15-20 strokes max. Overmixing develops gluten in the flour, making the cake tough instead of tender. The recipe’s moisture relies on a delicate crumb, not a workout for the batter.
- Bake in Two Rounds: Preheat your oven to 350°F, then place the cake pans inside for 5 minutes to equalize temperature. This ensures even baking and prevents domed tops. If your oven runs hot, reduce the temp to 325°F and bake 5-7 minutes longer—better a slightly underdone center than a burnt crust.
Dietary considerations for this betty crocker super moist chocolate cake
Gluten-Free Adaptation
For a gluten-free version, replace the 2.5 cups all-purpose flour with a 1:1 gluten-free baking flour blend like King Arthur Measure for Measure or Bob's Red Mill 1-to-1. These blends contain xanthan gum for proper structure. Add 1 tsp xanthan gum if your blend doesn't include it.
The buttermilk and oil remain the same, but increase the leavening to 2 tsp baking soda for lift. Bake at 325°F instead of 350°F to prevent over-browning—gluten-free cakes dry out faster. 🌱
Dairy-Free Options
Swap the buttermilk for dairy-free buttermilk (like Dairy-Free Culture brand) or make your own by mixing 1.5 cups unsweetened almond milk with 1.5 tbsp lemon juice.
Replace the 1.5 cups unsalted butter with 1.5 cups coconut oil (melted and cooled) and use dairy-free heavy cream (like Reddi-wip Non-Dairy) for the buttercream. The vanilla bean paste stays the same—just ensure it's dairy-free. These swaps keep the cake moist without sacrificing flavor. 🥛
Vegan Chocolate Cake
For a fully vegan version, use 1.5 cups coconut milk (full-fat) instead of buttermilk and 0.5 cup applesauce to replace the egg. Replace the butter with 1.5 cups coconut oil and the heavy cream with 1.5 cups coconut cream (chilled overnight).
For the buttercream, blend 4 cups powdered sugar, 1.5 cups coconut cream, and 1 tbsp vanilla extract until smooth. Add 1 tbsp aquafaba (chickpea brine) as a stabilizer if needed. Bake at 350°F for 35-40 minutes—vegan cakes often need extra time. 🌱
Lower Sugar Version
Reduce the granulated sugar to 1.5 cups and the brown sugar to 0.25 cup (packed). Add 0.25 cup unsweetened applesauce to the wet ingredients to maintain moisture. For the buttercream, use 2 cups powdered sugar and 1 tbsp monk fruit sweetener (optional) to cut calories.
The cake will still be rich but with 30% fewer sugars. Test with a toothpick at 25-30 minutes—lower sugar cakes bake faster. 🍚
Nut-Free Allergy Safe
This recipe is naturally nut-free, but always check labels on cocoa powder, vanilla extract, and powdered sugar for cross-contamination warnings. Use SunCups cocoa powder (nut-free facility) and McCormick vanilla extract (nut-free certified). For added safety, bake in a dedicated nut-free kitchen or clean all surfaces thoroughly.
The buttercream remains safe as long as you use nut-free brands of powdered sugar and cream. Always verify labels before purchasing ingredients. 🛡️
Nutrition facts
Frequently asked questions
Why does this cake stay moist longer than boxed mixes?
The secret lies in the combination of buttermilk, vegetable oil, and the instant coffee powder. Buttermilk adds moisture and tenderness, while oil creates a tender crumb instead of dryness from butter. The coffee powder enhances the chocolate flavor without bitterness and helps retain moisture during baking. Plus, the 10-minute rest in pans after baking locks in juices!
Can I make this cake in a single 9x13-inch pan instead of rounds?
Yes! Reduce the baking time to 25-30 minutes at 350°F for a sheet cake. Use the same batter but pour it all into the greased pan. For swirls, drop spoonfuls of the fudgy batter (with hot water) across the surface and swirl gently with a knife. The cake will be denser but still moist—perfect for layering with frosting or serving as a whole cake.
What's the best way to store leftovers?
Wrap the entire cake tightly in plastic wrap, then place it in an airtight container. Store at room temperature for 3-4 days or refrigerate for up to 1 week. For longer storage, slice and freeze individual portions between parchment paper for up to 3 months. The buttercream may separate when frozen—rewhip briefly before serving.
Why did my cake crack on top?
Cracking usually happens from sudden temperature changes or overbaking. Always let the cake cool in the pan for 10 minutes before removing it. Also, avoid opening the oven door early—this causes uneven cooling. If cracks appear, brush them with simple syrup (equal parts sugar and water) before frosting to disguise them. For next time, try baking at 325°F for 2-3 minutes longer to prevent over-rising.
Can I make this cake without buttermilk?
Mix 1.5 cups milk (any kind) with 1.5 tbsp lemon juice or vinegar, let sit for 5 minutes until thickened, then use as a 1:1 substitute. For extra moisture, add 1 tbsp melted butter to the wet ingredients. The tang from the acid still activates the baking soda properly for lift and tenderness.
