Ingredients for betty crocker super moist chocolate butter

Few ingredients create this luxurious texture—just butter, oil, and buttermilk working magic.

The butter-to-oil ratio is non-negotiable for that signature moisture. Use European-style butter (like Plugrá) if you can—it has higher fat content, which translates to richer layers. For the cocoa powder, Dutch-processed (like Hershey's Special Dark) is ideal—it dissolves smoothly and adds depth. The buttermilk must be room temperature; cold buttermilk curdles when mixed with melted butter. Store-bought buttermilk works fine, but if you're making your own, add 1.5 tablespoons of lemon juice to 1 cup of milk and let it sit for 5 minutes. The flour? Sift it—this prevents lumps and ensures a tender crumb. King Arthur or Bob's Red Mill brands are my go-tos for consistent results.

No buttermilk? Mix 1 tablespoon lemon juice or vinegar with 1 cup milk and let it sit for 5 minutes. Running short on butter? Substitute with an extra 0.25 cup oil, but the texture will be slightly less rich. Dutch-processed cocoa unavailable? Natural cocoa works at the same amount, but the flavor profile shifts slightly. For the chocolate chips, Ghirardelli or Guittard brands melt beautifully—avoid the cheaper store brands, which can seize when baking. The powdered sugar is purely for dusting between layers; if you prefer a less sweet finish, reduce it to 2 tablespoons. The heavy whipping cream should be cold when you whip it—let it chill in the fridge for 15 minutes before whipping for the best peaks.

This cake keeps beautifully. Store it in an airtight container at room temperature for up to 3 days, or refrigerate for 5 days. For longer storage, wrap tightly in plastic wrap and freeze for up to 3 months. The layers stay moist when frozen—just thaw at room temperature for 1 hour before serving. To reheat slices, microwave for 10-15 seconds with a splash of water on a paper towel. The whipped cream should be made fresh, but you can prepare it up to 2 hours ahead and store it in the fridge. For an extra-indulgent touch, drizzle with melted chocolate before serving.

Step-by-step instructions for betty Crocker's super moist chocolate butter recipe

Here's the method that delivers fudgy, moist layers with that signature buttery richness.

In a medium bowl, whisk together the 0.75 cup cocoa powder and 2 cups granulated sugar until completely combined. This creates a smooth base for the batter. In a separate saucepan, melt the 1 cup unsalted butter and 0.5 cup vegetable oil over low heat until fully liquid. Remove from heat and let cool slightly for 2 minutes—this prevents scrambling when combined with other ingredients.

While the butter mixture cools, pour 0.5 cup hot water into the dry cocoa-sugar mixture. Stir vigorously until it forms a thick paste. This step is crucial for creating the signature moist texture—it hydrates the cocoa and sugar, ensuring even distribution throughout the batter.

Add the cooled butter-oil mixture to the cocoa paste and whisk until smooth. In a separate bowl, sift together the 2 cups all-purpose flour, 0.5 tsp baking soda, and 0.5 tsp salt. Gradually add the dry ingredients to the wet mixture, alternating with the 1 cup buttermilk, beginning and ending with the flour.

Mix on low speed with an electric mixer for 1 minute until just combined. Overmixing develops gluten, which can make the cake dense. The batter should be thick but pourable. Stir in the 2 tsp vanilla extract and 1 cup dark chocolate chips by hand—this preserves the chocolate's texture and prevents melting.

Preheat your oven to 350°F. Grease two 8-inch round cake pans and line the bottoms with parchment paper. Divide the batter evenly between the pans. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out with moist crumbs (not wet batter). The edges should be set but the tops still slightly springy.

Here's the secret to moisture: as soon as the cakes come out of the oven, invert them onto a wire rack to cool completely. This ensures they don't absorb excess moisture from the pan, which would make them gummy. Let them cool for 30 minutes before assembling.

Once cooled, level the tops of the cakes if needed. Place the first layer on a serving plate and dust the top evenly with 0.25 cup powdered sugar. Spread a thin layer of 0.5 cup heavy whipping cream (whipped to soft peaks) over the sugar. Repeat with the second layer, then top with the remaining whipped cream.

Chill the assembled cake in the refrigerator for at least 1 hour before serving. This allows the layers to set properly and the flavors to meld. The buttermilk in the batter and the whipped cream topping work together to create that signature moist, velvety texture that keeps it tender for days.

Best sauces and condiments for this dish

Chocolate Ganache

For a decadent drizzle, melt ½ cup heavy cream and ½ cup semi-sweet chocolate chips together over a double boiler. Once smooth, let it cool slightly to 85°F before drizzling over the cake layers.

I use Ghirardelli chocolate bars for their rich, melt-in-your-mouth quality. Let the ganache set for 10 minutes before serving for a glossy finish that adds an extra layer of indulgence. 💫

Whipped Cream Variations

Swap the basic whipped cream for a vanilla bean whipped cream by infusing ½ cup warm cream with 1 vanilla bean (split and scraped) for 1 hour. Chill before whipping.

For a coffee twist, add 1 tsp instant espresso powder to the cream before whipping—this enhances the chocolate flavor beautifully. Store-bought whipped topping works in a pinch, but homemade is always superior. ✨

Berry Compote

Simmer 1 cup mixed berries (raspberries, blueberries, or strawberries) with 2 tbsp sugar and 1 tbsp lemon juice over medium heat for 5-7 minutes until thickened. Strain and cool before spreading between layers.

I prefer frozen organic berries for year-round availability—they burst with flavor. This adds a bright contrast to the rich chocolate. 🍓

Salted Caramel Sauce

Heat ½ cup granulated sugar in a saucepan until melted and amber-colored. Slowly whisk in ¼ cup heavy cream and 2 tbsp butter, then finish with a pinch of flaky sea salt.

Let cool slightly before drizzling over the cake. The salt enhances the chocolate flavor, creating a sophisticated balance. Store in an airtight container for up to 1 week. 🧂

Peanut Butter Swirl

Mix ½ cup creamy peanut butter with 2 tbsp powdered sugar and 1 tsp vanilla extract until smooth. Spread a thin layer of batter in the pans before adding the remaining batter, then swirl in the peanut butter mixture with a knife.

Bake as directed—this adds a nutty contrast that pairs perfectly with chocolate. Use Skippy or Jif for consistent results. 🥜

Espresso Glaze

Combine 1 cup powdered sugar, 2 tbsp strong brewed coffee, and 1 tbsp heavy cream until smooth. Drizzle over the cake layers and let set for 15 minutes.

The coffee intensifies the chocolate flavor without overpowering it. For extra shine, brush with 1 tsp corn syrup before applying the glaze. This is a game-changer for chocolate lovers. 💡
