Desserts
This Betty Crocker-style super moist chocolate cake delivers the fudgy depth and buttermilk-infused tenderness that makes it a classic dessert staple. The secret lies in precise ingredient ratios and a foolproof mixing technique that ensures every slice stays moist for days.
I’ve perfected this recipe over years of baking, and it’s become the go-to for birthdays, holidays, and spontaneous cravings alike.
The cake’s signature moisture comes from a combination of buttermilk and vegetable oil, which keep the crumb tender without making it dense. A simple glaze or cream cheese frosting elevates it further, but the cake itself stands strong on its own—rich, velvety, and packed with chocolate flavor.
This isn’t just a cake; it’s a restaurant-quality dessert you can bake at home.
What sets this recipe apart is its reliable texture—no dry crumbs or overly sweet aftertaste. The buttermilk reacts with baking soda to create a fine, even crumb, while the oil ensures that moisture stays locked in.
Whether you’re feeding a crowd or treating yourself, this cake delivers consistent, professional results every time.
Ready in just one hour, it’s perfect for last-minute celebrations or meal prep. Pair it with whipped cream, fresh berries, or a dusting of cocoa powder for the ultimate indulgence. Let’s get baking—this is the chocolate cake you’ll reach for again and again.
Ingredients for betty crocker super moist chocolate cake
Twelve ingredients. One hour. A cake so moist it’ll fool even Betty Crocker herself.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for even texture |
| Unsweetened Cocoa Powder 🍫 | 1 cup | Dutch-processed for smoothness |
| Granulated Sugar 🍚 | 2 ¼ cups | White or light brown |
| Vegetable Oil 🫒 | 1 cup | Light or canola preferred |
| Buttermilk 🥛 | 1 ½ cups | Homemade or store-bought |
| Distilled White Vinegar 🍶 | 1 tbsp | For homemade buttermilk |
| Milk 🥛 | ½ cup | Whole milk for richness |
| Baking Soda 🧪 | 2 tsp | Freshly measured |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Vanilla Extract 🌿 | 2 tsp | Pure, high-quality extract |
| Dark Brown Sugar 🍚 | ½ cup | Packed firmly |
| Semisweet Chocolate Chips 🍫 | 2 cups | High-quality chips preferred |
| Hot Water 💧 | ½ cup | For chocolate chips |
The cocoa powder and chocolate chips are non-negotiable here. Hershey’s Special Dark or Ghirardelli cocoa powder delivers that deep, rich flavor—none of that bitter aftertaste. Grab the semisweet chocolate chips from the bakery section, not the dollar store bin. The buttermilk? If you don’t have it, mix 1 tbsp vinegar + 1 cup milk and let it sit for 5 minutes. The baking soda is the secret—it reacts with the buttermilk to create that signature tender crumb. Bob’s Red Mill or King Arthur flour ensures a fine texture, but any good all-purpose will work. Don’t skimp on the vanilla—Nielsen-Massey or McCormick pure extract makes all the difference.
No buttermilk? Sour cream or plain yogurt works in a pinch—just use the same amount. Running low on chocolate chips? Chop a 6-oz bar of dark chocolate (70% cocoa or higher) and melt it with the hot water. The vinegar is key for homemade buttermilk—distilled white vinegar is best, but apple cider vinegar works too. For a richer cake, swap half the granulated sugar for dark brown sugar. The oil keeps this cake moist without adding greasiness—light olive oil or canola oil are foolproof. If you’re feeling fancy, add a pinch of espresso powder to deepen the chocolate flavor.
This cake stays moist for 5 days at room temperature, wrapped tightly in plastic. For longer storage, slice and freeze individual portions—they’ll taste fresh when reheated. The batter can be made 24 hours ahead and stored in the fridge. Double the recipe and freeze half for future cravings. Leftovers? Warm slices in the microwave for 10 seconds—they’ll be just as tender as the day you baked them. Pair with whipped cream or a dusting of cocoa powder for the ultimate indulgence.
Why You'll Love This Recipe
- No Mixer Needed: I swear by this recipe because it’s the only chocolate cake I can make without beating myself into submission. Just fold the dry ingredients into the wet—no electric mixer required—and the buttermilk keeps it tender without overworking the batter.
- Rich Without Bitterness: That unsweetened cocoa powder packs a punch, but the sugar and vegetable oil smooth it out into something decadent, not harsh. Honestly, I’ve tried fancier recipes with Dutch-processed cocoa, but this one hits the sweet spot every time.
- Birthday Party Ready: Serve it plain for a crowd or dress it up with whipped cream and berries for a special occasion. The layers stay moist for hours, so you’re not stuck with dry cake by the end of the party—(yes, even on a Tuesday night).
- Budget-Friendly Leftovers: A single box makes two 9x13-inch pans, which means I can freeze half for another day. The oil and buttermilk keep it from tasting stale, and it’s cheaper than buying a pre-made cake that’ll crumble by dessert time.
Step-by-step instructions for Betty Crocker super moist chocolate cake
The secret to this legendary cake lies in the buttermilk and cocoa powder combination—let's build it layer by layer.
Prepare the Buttermilk Mixture
In a medium bowl, combine the 1.5 cups buttermilk, 0.5 cup milk, 2 tsp vanilla extract, and 1 tbsp distilled white vinegar. Stir gently until fully blended. This mixture is the foundation of the cake's signature moisture—don't skip the vinegar, as it activates the buttermilk's acidity for better texture.
Let this sit for 5 minutes while you prepare the dry ingredients. The slight thickening that occurs during this time helps create a tender crumb. If you're using store-bought buttermilk, no additional preparation is needed beyond mixing.
Combine Wet and Dry Ingredients
In a separate large bowl, whisk together the 1 cup unsweetened cocoa powder, 2.5 cups all-purpose flour, 2.25 cups granulated sugar, 0.5 cup dark brown sugar, 2 tsp baking soda, and 1.5 tsp salt. Sift the flour mixture once to eliminate any lumps—this ensures a smooth, even texture throughout the cake.
Create a well in the center and pour in the buttermilk mixture along with the 1 cup vegetable oil. Using a hand mixer on low speed, gradually combine the ingredients until just mixed—about 1 minute. Overmixing develops gluten, which can make the cake dense. Stop mixing as soon as the batter comes together.
Fold in Chocolate Chips
In a small bowl, heat the 0.5 cup hot water until it's just steaming (not boiling). Pour this over the 2 cups semisweet chocolate chips and let them sit for 1 minute to soften. This creates a fudgy, intense chocolate flavor that permeates the cake.
Using a spatula, gently fold the softened chocolate mixture into the batter until evenly distributed. The goal is to maintain the batter's airiness while incorporating the chocolate—don't overmix. The chocolate chips should be dispersed throughout but still visible in each slice.
Bake to Perfect Moisture
Preheat your oven to 350°F and grease two 9-inch round cake pans thoroughly. Divide the batter evenly between the pans. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out with only a few moist crumbs—no wet batter should cling to it.
The cake should have a slightly domed top with a crackly crust on the edges. If the top browns too quickly, tent the pans with aluminum foil after 20 minutes of baking. Let the cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely before frosting.
Pro Tips For Making Betty Crocker Super Moist Chocolate Cake
- STOP MIXING DRY INGREDIENTS: The recipe calls for sifting flour and cocoa—but I learned the hard way that folding dry ingredients after creaming butter and sugar keeps air bubbles trapped. Dump everything in the bowl at once, then mix just until combined. Overmixing turns cake dense, and nobody wants that.
- MEASURE COCOA RIGHT: That "1/3 cup cocoa" isn’t packed-down cocoa. Spoon it into the measuring cup and level it off—no pressing. Too much cocoa makes the cake bitter and dry. (Yes, even if the recipe says "unsweetened.") If you’re using Dutch-process cocoa, reduce sugar by 1 tablespoon—it’s more intense.
- BAKE UNTIL SPRINGY: The cake’s done when the edges pull away from the pan and a toothpick comes out with a few moist crumbs—not wet batter. Ovens vary, so start checking at 25–30 minutes. If the top cracks early, tent with foil before it browns—this isn’t a crime, it’s texture insurance.
- SWAP BUTTERMILK LAST: The recipe wants buttermilk at room temp, but I’ve ruined batches by adding it too early. Mix the dry ingredients first, then the wet—except the buttermilk. Stir it in right before pouring into pans. Cold buttermilk curdles when mixed with oil, and nobody wants lumpy cake. (Yes, even if you’re in a hurry.)
Health benefits of this recipe
Rich Chocolate Flavor
This cake delivers a deep, satisfying chocolate experience thanks to the combination of 1 cup Dutch-processed cocoa powder and 2 cups semisweet chocolate chips. Dutch-processed cocoa has a smoother, less bitter taste, while the chocolate chips add pockets of fudgy intensity.
I recommend using Hershey’s Special Dark cocoa powder for that classic Betty Crocker richness. The hot water technique for softening the chips ensures they melt evenly throughout the batter, creating a marbled effect in every slice. 🍫
Balanced Sugar Content
The recipe uses a mix of 2.25 cups granulated sugar and 0.5 cup dark brown sugar to balance sweetness and moisture. The granulated sugar dissolves smoothly for even distribution, while the brown sugar adds caramel notes and helps retain moisture.
This combination prevents the cake from becoming overly sweet or dry. For a subtler flavor, reduce the granulated sugar by ¼ cup and increase the brown sugar by the same amount.
Heart-Healthy Fats
The 1 cup vegetable oil in this recipe provides heart-healthy fats that keep the cake moist without adding saturated fat. Unlike butter, oil doesn’t solidify when refrigerated, so the texture remains tender even after storage.
For a lighter option, use light olive oil—it has a slightly lower fat content while still delivering rich flavor. The oil also helps create a fine, even crumb structure that’s easy to slice. 💪
Protein for Satiety
While primarily a dessert, this cake contains about 4 grams of protein per serving thanks to the egg yolks and milk in the batter. The protein helps balance the sugar content, making it a slightly more satisfying treat.
For added protein, consider folding ½ cup Greek yogurt into the batter—it boosts the protein content to 6 grams per serving without altering the texture significantly.
Antioxidant Boost
The cocoa powder and dark chocolate chips in this cake are packed with antioxidants, particularly flavonoids and polyphenols, which help combat oxidative stress in the body. Dark chocolate with at least 70% cocoa provides the highest antioxidant levels.
Enjoying this cake in moderation can contribute to your daily antioxidant intake, supporting overall health. 🌿
Energy from Carbs
The cake provides a quick energy boost thanks to its carbohydrate-rich ingredients, including flour, sugar, and chocolate. The combination of simple and complex carbs ensures a steady release of energy, making it a great option for post-workout recovery or a midday pick-me-up.
For a lower-carb version, substitute ½ cup of the flour with almond flour, though this may slightly alter the texture.

Frequently asked questions
Why does this cake stay moist longer than other chocolate cakes?
The secret lies in the buttermilk and vegetable oil combo. Buttermilk creates a tender crumb through its acidity, while oil (not butter) keeps moisture locked in without adding saturated fat. The 1 cup vegetable oil and 1.5 cups buttermilk work together to prevent drying out for 5-7 days when stored properly.
Can I make this cake in a single 9-inch pan instead of two?
Yes, but expect a thicker, denser cake. Reduce baking time to 40-45 minutes at 350°F and check for doneness with a toothpick. For best results, stick with two pans—they create lighter layers that stay moist longer. If you must use one pan, consider reducing the recipe by half.
What’s the best way to store leftovers to keep them moist?
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 5 days. For longer storage, slice and freeze portions—reheat in the microwave for 10-15 seconds to restore moisture. Never refrigerate unwrapped cake, or it’ll dry out.
Can I substitute buttermilk if I don’t have any?
Mix 1 cup milk + 1 tbsp vinegar (or lemon juice) and let sit for 5 minutes until slightly thickened. For extra richness, use 1 cup plain yogurt or sour cream instead. Avoid using regular milk alone—it won’t create the same tender crumb. The acidity in these substitutes is key for moisture.
How do I fix a cake that’s cracked on top?
Cracking is normal—it just means your cake is baking perfectly! If the cracks are deep, brush them with a simple glaze (½ cup powdered sugar + 1 tbsp milk) to hide them. For future bakes, tent the pans with foil after 20 minutes if the top browns too quickly. The cracks won’t affect taste or texture—they’re just part of the cake’s charm!
