Ingredients for betty crocker super moist chocolate cake
Nine pantry staples transform into Betty Crocker’s signature fudgy, moist chocolate cake layers.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for light texture |
| Unsalted Butter 🧈 | 1 ½ cups | Room temperature, full-fat |
| Granulated Sugar 🍚 | 2 cups | White or light brown |
| Cocoa Powder 🍫 | ¾ cup | Dutch-processed preferred |
| Buttermilk 🥛 | 1 cup | Fresh, not powdered |
| Sour Cream 🥛 | ½ cup | Full-fat for moisture |
| Large Eggs 🥚 | 2 whole | Room temperature, fresh |
| Vanilla Extract 🌿 | 2 tsp | Pure, not imitation |
| Baking Soda 🧂 | 1 tsp | Pure baking soda |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Vegetable Oil 🫒 | ½ cup | Light or canola |
| Hot Water 💧 | ½ cup | For simple syrup |
| Granulated Sugar 🍚 | ¼ cup | For syrup glaze |
The cocoa powder is non-negotiable here—Dutch-processed gives that deep, velvety flavor, but regular cocoa works in a pinch. Ghirardelli or Hershey’s Special Dark are my go-tos, but the store brand works fine. Butter needs to be room temperature—no cold chunks in your batter. For buttermilk, grab the carton from the dairy section, not the powdered kind. And trust me, fresh eggs make all the difference in that tender crumb. The sour cream keeps everything moist for days, so don’t skip it—even if it’s not in the original Betty Crocker box.
No buttermilk? Mix 1 tbsp vinegar or lemon juice with 1 cup milk and let sit 5 minutes. Out of cocoa powder? Melted chocolate + 1 tbsp cornstarch works in a bind. The simple syrup glaze? Equal parts sugar and hot water, stirred until dissolved. For extra richness, swap half the flour for cake flour if you’ve got it. The vanilla extract should smell strong—if it’s faint, grab a new bottle. And if you’re worried about dryness, add 1 tbsp extra sour cream to the batter. This cake is forgiving, but these little tweaks take it over the top.
This cake stays moist for 5 days if wrapped tightly in plastic. For longer storage, freeze portions for up to 3 months. I always bake mine in two 9-inch pans—one day ahead is perfect for celebrations. The glaze sets quickly, so brush it on right after baking. And if you’re feeling fancy, dust with powdered sugar right before serving. Leftovers? Microwave 10 seconds to revive the softness.
Why You'll Love This Recipe
- No Mixer Needed: I swear by this recipe when my stand mixer’s on the fritz—just creaming butter and sugar by hand gives those fluffy layers. The buttermilk keeps it tender without requiring extra steps, and honestly? My arms thank me.
- Rich Without Bitterness: That cocoa powder and butter combo delivers deep, velvety chocolate flavor without tasting like a sad dessert. The sugar balances it perfectly, so it’s not too heavy—just pure, satisfying chocolate that doesn’t need frosting to shine.

- Leftovers That Last: I’ve had this cake sit in the fridge for days and still taste moist. The flour and butter create a sturdy crumb that doesn’t dry out, so it’s perfect for meal prep or when you’re too tired to bake twice. (Yes, even on a Tuesday night.)
Step-by-step instructions for Betty Crocker's super moist chocolate cake
Here's how to create rich, fudgy layers that stay moist for days—no dry crumbs in sight.
Cream Butter and Sugars Together
In a large mixing bowl, combine the 1.5 cups unsalted butter and 2 cups granulated sugar. Using an electric mixer on medium speed, beat until the mixture becomes light and fluffy—about 3-4 minutes. You'll notice the butter and sugar blend into a pale, airy consistency, which is crucial for that tender cake texture.
This creaming process incorporates air into the batter, helping the cake rise properly and stay moist. If your butter isn't completely room temperature, place the bowl over a pot of warm water for a few minutes to soften it first. The butter should be soft enough to leave a slight indent when pressed but not melted.
Add Eggs and Mix Well
Add the 2 whole large eggs one at a time, mixing well after each addition. Then stir in the 2 teaspoons vanilla extract until fully combined. The mixture should be smooth and slightly thickened. Be sure to scrape down the sides of the bowl to ensure all ingredients are incorporated evenly.
This step ensures the eggs are fully emulsified with the butter and sugar mixture, which helps create a stable structure for the cake. The vanilla extract adds depth of flavor, so don't skip this step—it makes a noticeable difference in the final taste.
Combine Dry Ingredients
In a separate bowl, sift together the 2.5 cups all-purpose flour, 0.75 cup cocoa powder, 1 teaspoon baking soda, and 0.5 teaspoon salt. This sifting step prevents lumps and ensures even distribution of ingredients, which is key for a smooth batter. Gradually add this dry mixture to the wet ingredients while mixing on low speed.
Mix just until combined—about 1 minute—being careful not to overmix. Overmixing develops gluten in the flour, which can make the cake tough. The batter should be thick and smooth, with no visible flour streaks remaining.
Incorporate Buttermilk and Sour Cream
Add the 1 cup buttermilk and 0.5 cup sour cream to the batter, mixing on low speed until just combined. The buttermilk and sour cream add moisture and tenderness to the cake. Mix for about 30 seconds to ensure everything is evenly distributed without overworking the batter.
This combination of buttermilk and sour cream is what makes this cake so incredibly moist. The acidity in buttermilk helps activate the baking soda, while the fat in sour cream keeps the crumb soft and rich. The batter should be thick but still pourable at this stage.
Prepare the Syrup and Bake
In a small saucepan, combine the 0.5 cup hot water and 0.25 cup granulated sugar. Bring to a boil for 1 minute, then remove from heat and let it cool slightly. Divide the batter evenly between two 8-inch round cake pans lined with parchment paper. Pour 2 tablespoons of the syrup over each cake layer.
Bake at 350°F for 25-30 minutes or until a toothpick inserted into the center comes out clean. The edges should be set, but the center should still have a slight bounce. Rotate the pans halfway through baking for even cooking. As soon as the cakes are done, remove them from the oven and immediately pour the remaining syrup over the hot cakes.
Cool and Layer
Let the cakes cool in their pans for 10 minutes, then transfer them to a wire rack to cool completely. Once cooled, use a serrated knife to level the tops if needed. To assemble, place one cake layer on a plate, spread a thin layer of chocolate frosting (if using), and top with the second layer. The syrup you poured over the hot cakes ensures they stay moist for days.
This cake is best served at room temperature, allowing the flavors to meld together perfectly. The combination of buttermilk, sour cream, and the simple syrup creates layers that are rich, fudgy, and incredibly moist—just as Betty Crocker intended. Enjoy with a dollop of whipped cream or a scoop of vanilla ice cream for the ultimate indulgence.
Pro Tips For Making Betty Crocker Super Moist Chocolate Cake
- Sift the Cocoa Twice: The recipe calls for cocoa powder, but I’ve learned to sift it twice—once when measuring and again when folding it into the butter. This breaks up any clumps and keeps the batter smooth, which means no weird pockets of dry cocoa in your cake. Trust me, your first bite will taste more even if you do this.
- Whisk the Buttermilk Cold: The buttermilk in this recipe is non-negotiable for moisture, but I’ve ruined cakes by using warm or slightly separated buttermilk. Whisk it right before mixing and keep it in the fridge until the last second—cold buttermilk blends better and doesn’t curdle when hit with baking soda. Your layers will stay tender, not gummy.
- Stop Mixing at "Just Combined": Overmixing is the enemy of a light cake. Once the flour and buttermilk are just combined—no streaks of dry flour left—stop. I used to think "more mixing = better cake," but this batter is delicate. Overdo it, and you’ll end up with a dense, tough slice instead of that classic moist crumb. One more stir after that, and you’re golden.
- Grease the Pan And Line It: This recipe’s cake is so rich it’ll stick if you’re not careful. Grease your pan thoroughly with butter or oil, then line the bottom with parchment paper—even if the recipe doesn’t say to. I’ve pulled cakes off the pan only to find the bottom stuck like glue. A little extra effort here saves a sad, broken cake later.
Make-ahead tips for this recipe
Prep Ahead Strategy
Bake the cake layers one day in advance—this allows flavors to develop fully while keeping the texture perfectly moist. After cooling completely, wrap each layer tightly in plastic wrap and store at room temperature.
The simple syrup glaze locks in moisture, so you won’t need to refrigerate unless your kitchen exceeds 75°F. 💫
Freezing for Later
For longer storage, freeze individual layers for up to 3 months. Wrap each layer in plastic wrap, then place in a freezer bag with all air squeezed out.
Thaw overnight in the fridge before assembling. The texture remains fudgy, not dry, because the syrup prevents moisture loss during freezing. Label bags with dates to track freshness.
Make-Ahead Frosting
Prepare your favorite chocolate frosting 2 days ahead and store it in an airtight container in the fridge. Bring it to room temperature before assembling the cake—this ensures smooth, spreadable consistency.
I like to add 1 teaspoon hot coffee to the frosting for extra depth of chocolate flavor. Refrigerate unused frosting for up to 5 days.
Assembly Timeline
Assemble the cake 4-6 hours before serving to let the frosting set properly. Place the first layer on a plate, spread frosting evenly, then add the second layer. Chill in the fridge for 2 hours before slicing.
This prevents the frosting from sliding off while keeping the layers tender. For a showstopper presentation, dust with powdered sugar right before serving. ✨
Transporting for Events
Transport the cake in its original pans or a sturdy cake carrier to maintain stability. Keep it at room temperature in a cool, dry place (like a car trunk) for up to 4 hours.
If traveling long distances, pack the layers separately in insulated containers with ice packs to prevent temperature shifts. The syrup glaze acts as a natural moisture barrier during transport.
Reviving Stale Slices
If slices lose moisture overnight, revive them by wrapping in a damp paper towel and microwaving for 10-15 seconds. The steam reactivates the syrup, restoring that fudgy texture. For a quick fix, brush slices with a light syrup glaze (equal parts sugar and water) before serving.
Leftovers stay fresh for 3-4 days when stored properly in an airtight container.

Frequently asked questions
Why does this cake stay moist longer than others?
The secret lies in the combination of buttermilk and sour cream, which add moisture while keeping the crumb tender. The simple syrup poured over hot layers locks in freshness for 5 days, while the oil-based batter prevents dryness. Unlike traditional recipes, this version avoids overmixing to maintain a delicate texture.
Can I make this cake in a single 9-inch pan instead of two?
Yes, but expect a taller, denser cake. Reduce baking time to 30-35 minutes and check for doneness with a toothpick. For best results, use a 9x13-inch pan and bake at 325°F for 40-45 minutes. The layers won't be as distinct, but the moisture will still shine through.
What’s the best way to store leftovers?
Wrap slices tightly in plastic wrap and store at room temperature for 3-4 days. For longer storage, freeze individual portions for up to 3 months. To revive stale slices, microwave for 10 seconds with a damp paper towel. The syrup glaze keeps them fudgy even after reheating.
How do I fix dry cake layers?
If your cake turns out dry, the issue is likely overbaking or missing the syrup step. For future batches, ensure the toothpick comes out with moist crumbs, not clean. Brush dry slices with a light syrup glaze (equal parts sugar and water) or a thin layer of chocolate ganache. The buttermilk and sour cream combo should prevent dryness if followed correctly.
Can I substitute sour cream with yogurt?
Plain yogurt works in a pinch, but it may make the cake slightly tangier. Use ½ cup full-fat Greek yogurt and reduce the buttermilk to ½ cup to balance moisture. For best results, stick to sour cream—its fat content creates that signature rich texture. The flavor difference is subtle but noticeable.
