Ingredients for betty crocker butter recipe chocolate cake mix
Twelve essential ingredients transform Betty Crocker's mix into velvety, restaurant-quality chocolate cake.
| Ingredient | Amount | Notes |
|---|---|---|
| Betty Crocker Super Moist Chocolate Cake Mix 🍫 | 1 box | Unopened, standard 15.25oz box |
| Unsalted Butter 🧈 | 1 cup | Melted, full-fat preferred |
| Large Eggs 🥚 | 2 whole | Room temperature for even mixing |
| Buttermilk 🥛 | 1 cup | Homemade or store-bought |
| Vegetable Oil 🫒 | ½ cup | For cake mix instructions |
| Granulated Sugar 🍚 | 1 cup | For buttercream frosting |
| Powdered Sugar 🍚 | 3 cups | For buttercream frosting |
| Unsalted Butter 🧈 | 1 lb | Softened, for buttercream |
| Vanilla Extract 🌿 | 2 tsp | Pure extract for frosting |
| Milk 🥛 | ¼ cup | For cake mix instructions |
| All-Purpose Flour 🌾 | ½ cup | Sifted, for buttercream |
| Salt 🧂 | ¼ tsp | Fine sea salt for frosting |
The Betty Crocker Super Moist mix is the foundation, but unsalted butter and buttermilk are non-negotiable for that signature moisture. For the butter, Land O'Lakes or Plugrá brands work best—avoid salted varieties to prevent over-salting the delicate chocolate flavor. Buttermilk should be homemade (milk + vinegar) for tangier results, or Great Value brand if store-bought. The vegetable oil from the mix instructions balances richness, while the granulated sugar in the frosting ensures proper crystal formation for that signature gloss. King Arthur Flour all-purpose flour is ideal for the buttercream—its protein level creates the perfect balance of structure and tenderness.
No buttermilk? Substitute with 1 cup milk + 1 tbsp lemon juice or vinegar—let it curdle for 5 minutes. Running low on butter? Coconut oil works in a pinch for melting into the batter, though it adds subtle coconut notes. The frosting can accommodate powdered milk if powdered sugar is unavailable (use 1/4 cup powdered milk + 1/2 cup sugar). For extra richness, add 1 tbsp cocoa powder to the frosting, but reduce powdered sugar by 1/4 cup to maintain consistency. Pillsbury cake mix works as a substitute, though the flavor profile differs slightly—stick with Betty Crocker for authenticity.
Store the cake mix in a cool, dry place for up to 6 months after opening. Buttercream frosting keeps for 5 days refrigerated or 3 months frozen—wrap tightly in plastic wrap to prevent drying. For best results, bake the cake immediately after mixing—the butter and buttermilk work best when fresh. Double batches freeze beautifully: wrap each layer individually in plastic wrap before freezing. Thaw at room temperature for 2 hours before frosting to prevent condensation.
Why You'll Love This Recipe
- Foolproof Mix-In: I swear by this recipe because it’s basically foolproof—just dump the mix, add the butter, eggs, buttermilk, and oil, then let the box do the rest. No measuring cups, no sifting, no stress. Honestly, I’ve burned cakes before, but this one’s hard to mess up.
- Rich, Fudgy Magic: That buttermilk and butter combo? It’s what turns this into a dense, fudgy dream instead of a dry cake. The Super Moist mix keeps it tender, and the chocolate flavor is so deep it tastes like a bakery piece—not some sad boxed cake.
- Birthday or Boredom: Between us, this cake works for everything. Celebrating a birthday? Done. Need a last-minute dessert? Done. Even my picky teen devours it. The best part? It’s not just for cake—crumbled over ice cream or layered with frosting, it’s always a win.
- Budget Buster: I make this all the time because it’s cheap, filling, and feeds a crowd. A box of mix, a stick of butter, and a carton of buttermilk cost less than takeout, but the leftovers? They disappear faster than I can say “second slice.” Plus, no fancy ingredients to break the bank.
Step-by-step instructions for Betty Crocker chocolate cake mix butter recipe
Transform boxed mix into velvety perfection using these precise techniques.
Melt Butter and Prepare Mix
In a microwave-safe bowl, melt the 1 cup unsalted butter in 30-second intervals, stirring between each, until completely liquid but not hot to the touch. Let it cool slightly for 2 minutes—this prevents scrambling the eggs later. In a separate large mixing bowl, combine the unopened box Betty Crocker Super Moist Chocolate Cake Mix, 2 whole large eggs (room temperature), 1 cup buttermilk, 0.5 cup vegetable oil, and 0.25 cup milk. Mix on low speed for 1 minute until just combined.
The buttermilk creates tiny air pockets that make this cake exceptionally moist. If the batter looks too thick, add 1-2 tablespoons milk until it reaches a pudding-like consistency. Avoid overmixing—this develops gluten and makes the cake dense.
Incorporate Melted Butter and Bake
Gradually pour the melted butter into the batter while mixing on low speed for 30 seconds. This step ensures even distribution of fat throughout the batter, which prevents dryness. Pour the batter into two 9-inch round pans lined with parchment paper and greased with butter. Bake in a preheated 350°F oven for 28-32 minutes or until a toothpick inserted in the center comes out clean with moist crumbs clinging to it.
Real talk: Ovens vary. Start checking at 25 minutes—overbaking dries out the cake. The edges should pull away slightly from the pan, and the top should spring back when gently pressed. Let the cakes cool in the pans for 10 minutes before transferring to a wire rack to cool completely.
Prepare the Buttercream Frosting
In a stand mixer fitted with the paddle attachment, beat the 1 lb unsalted butter (softened to room temperature) on medium speed until smooth and creamy, about 3-4 minutes. Gradually add the 3 cups powdered sugar, 1 cup granulated sugar, 2 tsp vanilla extract, and 0.25 tsp salt, mixing on low speed until combined. Increase speed to medium and beat for 2-3 minutes until light and fluffy. If the frosting is too thick, add 1-2 tablespoons milk to reach a spreadable consistency.
This frosting ratio creates a balanced sweetness with just the right amount of salt to enhance the chocolate flavor. The buttercream should be smooth enough to pipe but thick enough to hold peaks. If lumps form, press the frosting through a fine-mesh sieve for a silky finish.
Assemble and Chill
Level the cooled cakes and place one on a serving plate. Spread a thin layer of frosting over the top to seal in moisture, then add a thicker layer for decorating. Place the second cake on top and frost the entire cake with the remaining buttercream. For a polished look, use a spatula to create swirls or smooth sides. Chill the cake in the refrigerator for 30 minutes before slicing to help the frosting set.
The chilling step is crucial—it prevents the frosting from sliding off and ensures clean slices. Serve at room temperature for the best texture contrast between the moist cake and rich frosting. Store any leftovers covered at room temperature for up to 3 days or refrigerated for up to 5 days.
Pro Tips For Making Betty Crocker Butter Recipe Chocolate Cake Mix
- Melt Butter Slowly: The box says "melted butter," but I learned the hard way—dumping cold butter straight into the mix makes it clump like a science experiment gone wrong. Warm it in the microwave for 20 seconds, stir, then let it sit for 10 seconds before adding. That’s the sweet spot for smooth batter.
- Use Room-Temp Eggs: Cold eggs? They’ll turn your batter into a lumpy mess that’s more frustrating than delicious. Take the eggs out 30 minutes before mixing and let them sit in warm water if you’re in a hurry. The batter will blend like silk, not fight you every step.
- Don’t Overmix the Batter: I used to beat this like I was training for the Olympics, but the second the flour disappears, stop. Overmixing develops the gluten and turns your cake into a dense brick. Mix just until combined—about 20 seconds after the dry ingredients vanish.
- Grease Pans Properly: This isn’t the time to half-ass it. Use butter (not oil) to grease your pans, then dust with flour and tap out the excess. The box mix is forgiving, but a well-greased pan guarantees clean slices and no crumbly edges. Skip this, and you’ll be scraping cake off your knife like it’s a crime scene.
Serving suggestions for this recipe
Classic Pairings
Serve this velvety chocolate cake with a tall glass of cold milk—the creamy texture mirrors the cake’s richness perfectly. I love whole milk for its natural sweetness, but vanilla almond milk adds a sophisticated twist. For coffee lovers, a strong espresso cuts through the frosting’s sweetness beautifully. 🥛
Fruit Accents
Fresh berries add a bright contrast to the dense chocolate. I recommend strawberries or raspberries sliced and arranged in a circular pattern on top. For a tropical vibe, mango slices or kiwi bring a refreshing acidity. Keep portions small—just enough to peek through the frosting for visual appeal.
Warm Sauces
Drizzle warm chocolate ganache over slices for a decadent touch. Heat ½ cup heavy cream with 4 oz chopped dark chocolate until smooth, then let it cool slightly before pouring. Another favorite is salted caramel sauce—its salty-sweet balance elevates every bite. Serve in small bowls for guests to self-drizzle.
Creamy Additions
Top individual slices with a dollop of whipped cream and a sprinkle of toasted coconut flakes for a tropical-inspired dessert. For a gourmet touch, add a chocolate-covered espresso bean or gold leaf flake—these elevate the presentation without overpowering the cake’s natural flavors.
Beverage Pairings
A glass of chilled red wine like Cabernet Sauvignon complements the chocolate’s depth, while sparkling wine adds a festive touch. For non-alcoholic options, chocolate milkshakes or iced coffee with whipped cream create a satisfying contrast. The buttercream’s richness pairs beautifully with the creamy, cold beverages.
Make-Ahead Serving
For events, assemble the cake a day ahead and store it in an airtight container at room temperature. Refrigerate for up to 3 days**—bring to room temperature before serving.
Slice just before guests arrive to maintain the perfect texture. This cake holds its moisture beautifully, making it ideal for stress-free entertaining. ✨

Frequently asked questions
Why does adding butter make this chocolate cake mix extra moist?
The butter creates tiny fat molecules that distribute evenly throughout the batter, trapping moisture and preventing dryness. When combined with buttermilk, it also develops tiny air pockets that keep the cake tender for days. This is why the texture stays velvety even after slicing!
Can I use salted butter instead of unsalted in this recipe?
Technically yes, but it may make the cake slightly saltier than intended. For best results, use unsalted butter and adjust the frosting's salt to taste. If you must use salted, reduce the frosting salt by 1/4 teaspoon to balance flavors. The buttermilk already adds enough tang without extra saltiness.
How do I fix a cake that's cracked on top?
Cracking usually happens from overbaking or opening the oven too soon. If it occurs, don't worry—the cake is still edible! Brush the cracks with simple syrup (equal parts sugar and water) and cover with extra frosting. For prevention, bake at 350°F and check at 25 minutes—the cake should spring back when gently pressed.
Can I make this recipe with a different Betty Crocker cake mix?
While this method works best with the Super Moist Chocolate mix, you can try it with other chocolate varieties. The butter and buttermilk will still enhance moisture, but flavors may vary slightly. For best results, stick with the original mix—it's formulated to complement the butter addition perfectly.
How can I make this cake gluten-free?
Replace the cake mix with a 1:1 gluten-free chocolate cake mix (like Betty Crocker's gluten-free version) and use a gluten-free flour blend for the buttercream. The butter and buttermilk additions still work—they actually help compensate for the lack of gluten structure. Just be sure to check all ingredients for hidden gluten sources.
