- All-purpose flour: Provides just the right structure to keep the cupcakes tender but sturdy enough to hold the filling.

Variations
I love making this recipe my own depending on the season or who’s coming over. These cakes are great for playing around with flavors and decorations, so don’t hesitate to switch things up and make it truly yours!
- Peanut Butter Filling: One time I swapped out the marshmallow cream for peanut butter frosting, and my family went crazy for that nutty surprise inside!
- Vegan Version: Use vegan butter and a dairy-free alternative for cream cheese, plus a flax egg substitute to make these completely plant-based without losing any decadence.
- Seasonal Sprinkles: For Halloween, I choose spooky sprinkles, but around Christmas, I swap to red and green nonpareils to keep the fun going year-round.
- Spicy Chocolate: Add a pinch of cinnamon or cayenne in the batter for a subtle spicy kick that balances the sweet marshmallow filling beautifully.
How to Make Chocolate Cauldron Cakes Recipe
Step 1: Mix Dry Ingredients to Perfection
Start by whisking together your flour, cocoa powder, baking powder, baking soda, and salt. I always sift these together to avoid any lumps—especially the cocoa powder—because it helps your cupcakes get that smooth, even chocolate color and texture. Set this dry mix aside while you prepare the wet ingredients so everything stays fresh and ready to blend.
Step 2: Whisk Wet Ingredients Until Smooth
In a medium bowl, beat your eggs, sugars, oil, and vanilla extract until the mixture is silky and homogeneous. It’s really important your eggs are at room temperature here; it makes the batter smoother and keeps your cupcakes from turning out dense. You’ll notice the sugars dissolve nicely, and this is when your batter starts smelling like a chocolate dream!
Step 3: Combine Wet and Dry Ingredients Gently
Pour half the wet ingredients into your dry mix, then add half of the buttermilk. Use a whisk to gently combine for a few seconds — don’t overmix! Repeat the process with the remaining wet ingredients and buttermilk. The batter will be thin, and that’s perfect! If you overwork it, your cupcakes could get tough, and we don’t want that.
Step 4: Bake Until Just Right
Fill your cupcake liners halfway with the batter—this keeps the cupcakes from spilling over or sinking. I learned the hard way that overfilling creates a hot mess! Bake at 350°F (177°C) for about 18-21 minutes. You’ll know they’re done when a toothpick comes out clean or with just a few moist crumbs. Let them cool completely before moving on; warm cupcakes won’t hold the marshmallow filling well.
Step 5: Whip Up the Marshmallow Filling
Beat marshmallow fluff, shortening, confectioners’ sugar, and vanilla extract together until fluffy — around 3-5 minutes. Trust me, this step is key for that light, pipe-friendly filling that sits perfectly inside the cakes. Transfer it to a piping bag and set it aside while you prepare the frosting.
Step 6: Make That Dreamy Chocolate Frosting
Melt your bittersweet chocolate gently over simmering water, then let it cool slightly—you don’t want it too hot or it’ll break the frosting. Beat room-temp cream cheese and butter until fluffy, then add sugar, cocoa, and salt. Slowly mix in the melted chocolate, then the sour cream. Continue beating until silky smooth. Pipe this into a bag with a star tip, and you’ll have the perfect frosting to frame your cauldrons.
Step 7: Assemble Your Chocolate Cauldron Cakes
Carefully cut cone-shaped holes from the centers of your cooled cupcakes — don’t cut all the way through! Pipe marshmallow filling generously into the holes so it slightly overflows. Quickly dunk the top into your sprinkles to get a fun, creepy cauldron effect. Finish by piping small dollops of chocolate frosting around the edges to create the cauldron’s rim. These little details make the cakes look like they’re bubbling witches’ cauldrons, and it’s just so much fun!
Pro Tips for Making Chocolate Cauldron Cakes Recipe
- Don’t Overmix Your Batter: I learned that gentle mixing keeps the cupcakes tender and airy—overmixing gives you dense cakes, and that’s just not the vibe here.
- Room Temperature Ingredients Matter: Having eggs and buttermilk at room temp helps your batter emulsify better and bakes more evenly.
- Cut Carefully for Filling: Use a sharp paring knife and small, slow cuts when hollowing out cupcakes so they don’t crumble apart.
- Pipe Quickly to Avoid Melted Filling: Once filled, dunk cupcakes in sprinkles right away — marshmallow filling can get sticky if left out too long.
How to Serve Chocolate Cauldron Cakes Recipe
Garnishes
I always top these cauldron cakes with Monster Mash sprinkles because they add that crunchy texture and colorful flair that really brings the Halloween spirit alive. If you want to get creative, mini edible eyes or candy bones add a wicked cool touch for kids and adults alike.
Side Dishes
If you’re serving this at a party, these cakes pair beautifully with a simple glass of cold milk or a rich coffee or mocha. For a more substantial dessert spread, add some fresh berries, whipped cream, or even a scoop of vanilla ice cream to balance out the chocolate richness.
Creative Ways to Present
One year, I arranged these cupcakes on a black platter surrounded by dry ice to create a spooky “smoking cauldron” effect — it’s a perfect showstopper for Halloween parties! You can also place them inside mini witches’ hats or decorated cupcake stands to really impress your guests.
Make Ahead and Storage
Storing Leftovers
I keep leftover Chocolate Cauldron Cakes in an airtight container in the fridge. They stay delicious for up to 3 days, but make sure the container isn’t too tight around the frosting to avoid smushing your cute cauldron rims!
Freezing
Freezing these works surprisingly well if you want to prep ahead. I freeze them before assembling the filling and frosting, then thaw in the fridge overnight before decorating. This keeps everything fresh and the marshmallow filling perfectly fluffy.
Reheating
To warm leftovers, I let the cupcakes sit at room temperature for 20-30 minutes so the frosting softens a bit, enhancing that creamy, melty texture without melting the decorations. Avoid microwaving if possible, or do it in short bursts on low power to keep the frosting intact.
FAQs
-
Can I use regular frosting instead of the marshmallow filling?
Absolutely! While the marshmallow filling gives a gooey texture and fun surprise, you can swap it with any frosting or cream cheese filling you prefer. Just keep in mind that marshmallow fluff has a uniquely light yet sticky texture that holds the sprinkles well for the cauldron effect.
-
What’s the best way to hollow out the cupcakes without breaking them?
I recommend using a sharp paring knife and cutting slowly in a cone shape, starting with a small incision and gradually widening it. Try to leave a sturdy wall of cake around the edges so your cupcake doesn’t crumble or collapse when filled.
-
Can I make these cupcakes gluten-free?
You can! Substitute all-purpose flour with a 1-to-1 gluten-free baking flour blend that contains xanthan gum for the best texture. Just be mindful that gluten-free batters sometimes need a touch more liquid or a bit less mixing.
-
How far in advance can I make Chocolate Cauldron Cakes Recipe?
You can bake the cupcakes up to 2 days before serving and keep them covered at room temperature or refrigerated. I usually leave filling and frosting for the day of serving to keep everything fresh and prevent sogginess.
-
What if I don’t have buttermilk?
No worries! You can make a quick buttermilk substitute by adding 1 tablespoon of white vinegar or lemon juice to ½ cup of milk and letting it sit for 5-10 minutes before using. This adds the acidity needed for the perfect crumb and rise.
Final Thoughts
This Chocolate Cauldron Cakes Recipe holds a special place in my kitchen because it’s not just about the incredible chocolate flavor or the marshmallow surprise; it’s about the joy of creating something whimsical and delightful that everyone remembers. I highly encourage you to try making these at home — whether for a Halloween bash, a themed party, or just because you deserve a treat that’s both fun and decadent.

- ¾ teaspoon baking powder
- ½ teaspoon baking soda
- ¼ teaspoon salt
- 2 large eggs, at room temperature
- ½ cup sugar
- ½ cup packed light brown sugar
- ⅓ cup canola oil
- 2 teaspoons Adams vanilla extract
- ½ cup buttermilk, at room temperature
For the marshmallow filling
- 1 cup Marshmallow Fluff (or prepared marshmallow cream)
- ½ cup vegetable shortening
- ½ cup confectioners sugar
- 2 teaspoons Adams vanilla extract
For the frosting
- 7 ounces bittersweet chocolate, finely chopped
- 4 ½ ounces cream cheese, room temperature
- 4 ½ tablespoons unsalted butter, room temperature
- 1 ½ cups confectioners’ sugar, sifted
- 3 tablespoons unsweetened Dutch-process cocoa powder
- Pinch of salt
- ½ cup plus 1 tablespoon sour cream
For assembly
- 2 oz Sweets & Treats Monsters Mash sprinkle mix
Instructions
- Make the cupcakes: Preheat the oven to 350°F (177°C) and line a 12-cup muffin pan with cupcake liners. In a large bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt until combined. In a separate bowl, whisk eggs, granulated sugar, brown sugar, canola oil, and vanilla extract until smooth. Alternately add the wet ingredients and buttermilk to the dry mixture, stirring gently until just combined to maintain a light texture. Pour the batter into liners filling halfway to prevent overflow or sinking. Bake for 18-21 minutes, or until a toothpick inserted comes out clean. Transfer to a wire rack to cool completely.
- Make the marshmallow filling: In a medium bowl, beat marshmallow fluff, vegetable shortening, confectioners sugar, and vanilla extract together for 3-5 minutes until light and fluffy. Transfer the filling to a piping bag and set aside.
- Make the frosting: Melt bittersweet chocolate in a heatproof bowl over simmering water, then cool until just barely warm. In a stand mixer with the paddle attachment, beat cream cheese and butter on medium-high speed until pale and fluffy, about 3-4 minutes. Gradually add confectioners sugar, cocoa powder, and salt. Beat in melted chocolate and sour cream until smooth and well combined. Transfer to a piping bag with a small open star tip and set aside.
- Assemble the cupcakes: Pour sprinkles into a bowl. Using a sharp paring knife, cut a cone-shaped hole in the center of each cupcake without cutting through the bottom. Pipe marshmallow filling into the hollow, filling just above the cupcake surface. Dip the top of each filled cupcake into the sprinkles to adhere to the marshmallow. Repeat for all cupcakes. Using the chocolate frosting, pipe small dollops around the edges of each cupcake to create a rim that resembles a cauldron. Store assembled cupcakes in airtight containers in the refrigerator until serving.
