Ingredients for betty crocker sour cream chocolate cake

Sour cream and buttermilk transform ordinary chocolate cake into velvety perfection.

Ingredient Amount Notes
All-Purpose Flour 🌾 2 ½ cups Sifted for lightness
Unsalted Butter 🧈 1 ½ cups Room temperature for creaming
Granulated Sugar 🍚 2 cups White sugar preferred
Cocoa Powder 🍫 ¾ cup Natural unsweetened cocoa
Sour Cream 🥛 1 cup Full-fat for moisture
Buttermilk 🥛 1 cup Fresh for tanginess
Large Eggs 🥚 2 whole Room temperature
Baking Powder 🍞 2 tsp Aluminum-free preferred
Salt 🧂 ½ tsp Diamond Crystal kosher
Vanilla Extract 🌿 2 tsp Pure alcohol-free preferred
Hot Water 💧 ½ cup For cocoa bloom
Vegetable Oil 🫒 ½ cup Light neutral flavor
Powdered Sugar 🍚 1 cup For frosting
Heavy Whipping Cream 🥛 ½ cup Cold for frosting

The sour cream is non-negotiable here—it's what makes this cake stay moist for days. Full-fat works best, so skip the low-fat version. For buttermilk, I always make my own by mixing milk with a splash of vinegar (the tang matters). The cocoa powder should be natural unsweetened—Dutch-processed cocoa will darken the batter too much. Ghirardelli or Hershey's Special Dark are my go-tos, but any natural brand works. Sift the flour and cocoa together to avoid dense layers. And trust me on the room-temperature butter—it creams better and doesn't leave lumps.

No sour cream? Greek yogurt at half the amount gets you close, though the texture won't be quite the same. Running out of buttermilk? Mix 1 tbsp vinegar or lemon juice with 1 cup milk—let it sit 5 minutes. For the frosting, powdered sugar should be sifted too (clumps are the enemy). The heavy cream needs to be cold—chill the bowl first if your kitchen runs warm. Want extra richness? Add 1 tbsp melted butter to the frosting. And if you're feeling fancy, swap half the powdered sugar for confectioners' sugar for a smoother finish.

This cake keeps beautifully—3 days at room temperature wrapped tightly, or 5 days in the fridge. The frosting stays fresh for 2 days if stored properly. To reheat slices, microwave for 10-15 seconds—just enough to melt the frosting without drying the cake. I always bake two 8-inch rounds because they disappear fast. Freeze unfrosted layers for 3 months if you're prepping ahead.

Step-by-step instructions for Betty Crocker's sour cream chocolate cake

Here's how to create a velvety, moist chocolate cake with layers that stay tender for days.

1

Cream Butter and Sugar for Maximum Lightness

In a stand mixer fitted with the paddle attachment, beat the 1.5 cups unsalted butter and 2 cups granulated sugar on medium speed for 4-5 minutes until the mixture is pale, fluffy, and nearly doubles in volume. This step is crucial—it incorporates air that will create those signature tender crumbs. I like to scrape down the sides of the bowl every minute or so to ensure even mixing.

Here's the thing—room temperature butter is key. If it's too cold, you'll end up with dense cake. Press the butter between two sheets of parchment paper and let it sit at room temperature for 30 minutes before starting. You'll know it's ready when it leaves a slight indentation when pressed with your finger but doesn't feel greasy.

2

Incorporate Wet Ingredients for Perfect Moisture Balance

Add the 2 whole large eggs one at a time, mixing on low speed after each addition until fully incorporated. Then stir in the 2 teaspoons vanilla extract and 1 cup sour cream. The sour cream adds that signature moisture and richness that makes this cake stand out from ordinary chocolate cakes.

Next, in a separate bowl, whisk together the 1 cup buttermilk, 0.5 teaspoon salt, and 2 teaspoons baking powder. This buttermilk mixture is our secret weapon—it creates that fine, even crumb structure while keeping the cake tender. The buttermilk also reacts with the baking powder during baking to produce carbon dioxide bubbles, which is what makes cakes rise properly.

3

Combine Dry Ingredients and Create the Batter

Gradually add the dry ingredients—2.5 cups sifted all-purpose flour and 0.75 cup cocoa powder—to the wet mixture in the mixer. Mix on low speed just until combined, about 30-45 seconds. You should still see a few flour streaks when you lift the paddle—overmixing develops gluten and makes the cake tough.

With the mixer still running on low, slowly pour in the 0.5 cup vegetable oil and mix until just combined. Then add the buttermilk mixture in a slow stream, mixing just until no dry spots remain. The batter should be thick but pourable. If it seems too thick, you can add 1-2 tablespoons hot water to help it flow better into the pans.

4

Bake with the Hot Water Trick for Even Rise

Preheat your oven to 350°F and prepare two 8-inch round cake pans by greasing them with butter and dusting with flour. Divide the batter evenly between the pans. Here's where the hot water comes in—I pour 0.5 cup hot water into a small saucepan and heat it until it's steaming but not boiling. Then I carefully pour this hot water around the outside of each cake pan before placing them in the oven.

This hot water bath creates steam during the initial stages of baking, which helps the cakes rise more evenly and develop that perfect dome shape. Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean with just a few moist crumbs clinging to it. The cakes should spring back when gently pressed in the center.

5

Frost and Serve for Ultimate Decadence

While the cakes are still warm, prepare the frosting by whipping together the 1 cup powdered sugar, 0.5 cup heavy whipping cream, and 1 teaspoon vanilla extract until smooth and fluffy. The cream should be cold when you start—this helps it whip up properly. I like to chill the bowl and beaters in the freezer for 10 minutes before whipping.

Let the cakes cool in their pans for 10 minutes, then transfer them to a wire rack to cool completely. Once cooled, level the tops if needed, then frost generously between the layers and on top. For extra decadence, I like to sprinkle a little extra cocoa powder on top before serving. The contrast of the cool, creamy frosting with the warm, moist cake is what makes this recipe truly special—each bite delivers that perfect balance of rich chocolate and tender crumb.

Pro Tips For Making Betty Crocker Sour Cream Chocolate Cake

  • Whisk Butter & Sugar First: DESCRIPTION: Skip mixing dry ingredients until the very end—whisk the butter and sugar together until light and airy (about 3-4 minutes). This recipe relies on that creamy texture to keep the cake tender, not dense. I used to rush this, and the result was a sad, compact brick instead of the moist, fluffy cake you’re after.
  • Sift That Cocoa: DESCRIPTION: Don’t just scoop the cocoa powder—sift it twice (once before mixing, once after) to avoid lumps. Chocolate cake is unforgiving with gritty texture, and sour cream already makes this recipe rich. A fine, even distribution means every bite is smooth, not sandy.
  • Don’t Overmix the Batter: DESCRIPTION: Once you fold in the flour, stop immediately after it’s just combined. Overmixing develops gluten, and this cake’s magic is in its soft, velvety crumb. I learned this the hard way—my first attempt was a chewy mess because I kept stirring like I was making pancakes.
  • Chill the Batter 10 Minutes: DESCRIPTION: Let the batter sit covered in the bowl for 10 minutes before baking. The sour cream needs time to hydrate the flour fully, and the eggs will firm up slightly, preventing a sunken center. Yes, it’s tempting to pop it in the oven right away, but trust me—this small pause makes all the difference.

Troubleshooting this dish

Cake Stuck in Pans

If your cake refuses to release from the pan, don’t force it—this causes cracks and tears. First, let the cake cool for 10-15 minutes before attempting to remove it. Run a thin offset spatula around the edges to loosen it, then tap the pan gently on the counter.

If it still sticks, place the pan upside down on a plate and invert—gravity often does the trick. For stubborn cases, chill the pan in the fridge for 5 minutes first. 💡

Dense or Dry Texture

Overmixing the batter is the #1 cause of dense cake. Mix dry ingredients just until combined—30-45 seconds max—and avoid over-whipping the egg mixture. If your cake turns out dry, the issue might be overbaking.

Check doneness with a toothpick after 25 minutes—it should have a few moist crumbs, not be completely clean. For extra moisture, brush warm layers with simple syrup (½ cup sugar + ¼ cup water, heated until dissolved) before frosting.

Uneven Rise or Sinking Center

An uneven rise often means the oven temperature wasn’t stable. Invest in an oven thermometer—many home ovens run 25-50°F hotter or colder than set. Place the thermometer near the cakes while preheating. If the center sinks, it likely overbaked.

Next time, reduce bake time by 2-3 minutes and check for doneness earlier. The hot water trick (pouring steaming water around pans) helps, but don’t skip preheating the oven for 15 minutes before baking.

Cracked Top or Sides

Cracks usually appear from sudden temperature changes or overmixing. To prevent them, avoid opening the oven door during the first 20 minutes of baking. If cracks form, they’re mostly cosmetic—just frost generously to mask them.

For extra insurance, place pans on the middle rack where heat circulates evenly. If your oven has hot spots, rotate pans halfway through baking. A lightly greased pan (with flour) also reduces sticking and cracking.

Frosting Too Thin or Grainy

Grainy frosting means your powdered sugar wasn’t sifted or had lumps. Always sift 1 cup powdered sugar before whipping. For a smoother finish, add 1 teaspoon corn syrup to the cream mixture before whipping.

If frosting is too thin, chill the bowl for 5 minutes before whipping again—cold cream whips better. For extra stability, add 1 teaspoon meringue powder (like Powdered Sugar Stabilizer from baking aisles) to prevent melting.

Burnt Edges or Pale Center

This classic "hot spots" issue happens when oven heat isn’t distributed evenly. Rotate your pans halfway through baking (after 15 minutes). If edges burn first, try baking on the lower rack. For a pale center, check doneness earlier—25 minutes is often enough.

If your oven runs hot, reduce temperature to 340°F and bake for 32-35 minutes. A dark metal pan can cause faster browning, so opt for lighter-colored pans if you have them.

Frequently asked questions

1

Can I use a boxed Betty Crocker chocolate cake mix for this recipe?

Yes! For a shortcut, use a 18.8-ounce boxed Betty Crocker chocolate cake mix and follow these adjustments: Replace 1 cup sour cream with 1 cup buttermilk, add 2 teaspoons vanilla extract, and mix in 0.5 cup vegetable oil. Bake as directed, but reduce time by 5 minutes since boxed mixes bake faster. The sour cream trick still works—just add it to the boxed mix batter before baking for extra moisture.

2

Why does sour cream make this cake so much better than regular chocolate cake?

The sour cream adds 3 key benefits: moisture retention (prevents dryness), tenderness (creates a fine crumb), and richness (enhances chocolate flavor). Regular cake recipes often use oil or melted butter, which can make cakes denser. Sour cream's fat content keeps the layers velvety while its acidity tenderizes the gluten in the flour. Without it, you risk a cake that dries out within hours.

3

What's the best way to store leftover cake?

For maximum freshness, wrap the unfrosted cake layers tightly in plastic wrap and store at room temperature for 3 days. Frosted cakes last 2 days at room temp. Refrigerate for 5 days (cover with foil) or freeze unfrosted layers for 3 months. To reheat, microwave 10-15 seconds—just enough to soften the frosting without drying the cake. The sour cream keeps it moist even after storage!

4

Can I make this cake in a bundt pan instead of round pans?

Use a 10-cup bundt pan and reduce batter by 1 cup (about 25% less). Grease it thoroughly and dust with flour. Bake at 350°F for 40-45 minutes—check with a toothpick at 35 minutes. The hot water trick still works (pour around the pan before baking). For frosting, use a piping bag to decorate the intricate patterns. The bundt shape holds frosting beautifully!

5

What if I don't have buttermilk? Can I substitute something?

Yes! Mix 1 tablespoon lemon juice or white vinegar with 1 cup milk, let sit 5 minutes until thickened. For extra tang, use 1 cup plain yogurt (Greek works best). Avoid buttermilk substitutes with strong flavors like sour cream—they'll alter the cake's balance. The buttermilk's acidity is key for proper rise and tenderness.
