Decadent Chocolate Surprise Cupcakes: A Must-Try Recipe from Julie Hasson’s Collection

Oh, hello there, baking enthusiasts! After what felt like an eternity battling the holiday rush – where I swear Target managed to siphon off a significant portion of my soul – I’m finally back in my happy place: the kitchen! While my work hours have been drastically cut (and yes, I’m still figuring out the whole “paying bills” puzzle), this newfound free time has been a surprising blessing. It’s allowed me to slowly, but surely, rekindle my long-lost cooking spirit. It’s a journey, but the aroma of fresh baking is certainly helping to mend my weary soul.

I sincerely hope everyone had a wonderful and relaxing holiday season. Mine was quite decent, filled with a few delightful surprises. One of the most practical and exciting gifts I received was a much-needed kitchen pantry! You have no idea what a game-changer this has been. My countertops, once perpetually cluttered with my bread maker, the trusty George Foreman grill, and an assortment of random pans, are now gloriously clear. It’s a small victory, but one that brings immense joy. But the real gem, the one that has been on my wishlist for what feels like an eternity, was Julie Hasson’s 125 Best Cupcake Recipes. I honestly couldn’t believe my parents actually shelled out $20 for it, but it’s an incredibly difficult book to find used, so it was a truly cherished gift. This book is a treasure trove of baking inspiration, and I’ve been eager to dive in.


Freshly baked Chocolate Surprise Cupcakes with marshmallow peeking out

With my new cookbook in hand and an overflowing drawer of cupcake liners (Christmas may be over, but I still had a stash of adorable winter-themed ones I got on clearance last year, complete with matching toppers!), I knew it was time for a baking adventure. The first recipe that caught my eye, and captured my heart, was Julie Hasson’s “Chocolate Surprise Cupcakes.” As a self-proclaimed marshmallow fanatic, the idea of a gooey marshmallow hidden inside a rich chocolate cupcake was simply irresistible. The concept is ingeniously simple yet utterly delightful: you bake the chocolate cupcakes, then, while they’re still warm, you scoop out a little center and pop in a marshmallow. The warmth of the cake softens the marshmallow, creating a luscious, melt-in-your-mouth surprise with every bite. You’re supposed to let them melt a little and then gently squish the top down to encase the marshmallow, but let’s be honest, after a long day, I was far too tired to stand around and wait for that level of perfection. So, in true “I’m just going to cover it with frosting” fashion, I opted for the easier route. And honestly, they turned out just as wonderfully decadent!

The journey wasn’t entirely smooth sailing, I must confess. When it came to frosting these beauties, I hit a snag. I had completely run out of pastry bags, so I resorted to my usual makeshift solution: sandwich bags. This often works perfectly fine for me, but this time, I think I overfilled them, and in a glorious (and messy) fashion, two bags dramatically ripped open. Picture me, covered in chocolate fudge frosting, looking utterly defeated. Fortunately, my amazing best friend had recently gifted me this fantastic cake decorating press (think a cookie press, but for icing, with various tips!). After a quick cleanup, a deep breath, and wasting only a small amount of that precious frosting, I managed to finally get these cupcakes beautifully adorned. And let me tell you, this chocolate fudge frosting is pure magic – rich, smooth, and utterly “cupcakelicious!” Who cares if my sprinkles don’t perfectly match the winter theme? They add a pop of color, and more importantly, these cupcakes taste absolutely divine!

The Ultimate Chocolate Surprise Cupcakes Recipe

Ingredients for Chocolate Surprise Cupcakes:

  • 1 cup all-purpose flour
  • 1/2 teaspoon baking powder
  • 1/4 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1 cup granulated sugar
  • 1/4 cup neutral oil (such as canola or vegetable oil)
  • 2 large egg whites
  • 1 teaspoon pure vanilla extract
  • 2 ounces unsweetened chocolate, melted and cooled slightly
  • 2/3 cup buttermilk
  • 2 tablespoons chocolate cream liqueur OR chocolate syrup (for an alcohol-free option)
  • 12 large marshmallows OR a generous handful of mini marshmallows

Ingredients for Decadent Chocolate Fudge Frosting:

  • 1 1/2 cups powdered sugar (confectioners’ sugar)
  • 3/4 cup unsweetened cocoa powder
  • 1/2 cup unsalted butter or baking margarine, softened to room temperature
  • 2 tablespoons chocolate cream liqueur OR milk (for an alcohol-free option)
  • 1 tablespoon strong brewed coffee OR milk (coffee enhances chocolate flavor beautifully!)

Instructions for Cupcakes:

  1. Prepare the Oven & Pan: Preheat your oven to 350°F (175°C). Line a 12-cup muffin pan with paper cupcake liners. This recipe yields exactly 12 perfect cupcakes.
  2. Combine Dry Ingredients: In a small bowl, whisk together the flour, baking powder, baking soda, and salt. Make sure these are well combined to ensure even leavening throughout your cupcakes. Set aside.
  3. Mix Wet Ingredients (First Stage): In a separate, larger bowl, beat together the granulated sugar and oil until they are thoroughly combined and light.
  4. Add Eggs & Flavorings: Add the egg whites to the sugar-oil mixture, one at a time, beating well after each addition until fully incorporated. Then, beat in the vanilla extract and the slightly cooled melted unsweetened chocolate until the mixture is smooth and chocolatey.
  5. Alternate Wet & Dry: Gradually add the dry ingredient mixture and the buttermilk to the wet ingredients, alternating between the two and beginning and ending with the dry ingredients. Beat only until just combined – overmixing can lead to tough cupcakes.
  6. Fold in Final Flavor: Gently beat in the chocolate cream liqueur or chocolate syrup. This adds an extra layer of chocolatey depth and moisture.
  7. Fill & Bake: Scoop the batter evenly into the prepared cupcake liners, filling each about two-thirds full. Bake for 20-25 minutes, or until the tops spring back when lightly touched and a toothpick inserted into the center comes out clean.
  8. Cool & Create the Surprise: Let the cupcakes cool in the muffin pan for about 5 minutes. This allows them to set slightly. Then, carefully remove them from the pan and transfer them to a wire rack. While the cupcakes are still warm, use a small knife or a cupcake corer to cut out a small cone-shaped center from the top of each cupcake.
  9. Insert Marshmallow: Place one large marshmallow (or a small handful of mini marshmallows) into the hollowed-out center of each warm cupcake. If using large marshmallows, they should soften and melt slightly from the residual heat. If they stick up too much, gently press them down. If they still don’t quite sink in, don’t worry – your delicious frosting will hide any imperfections!

Instructions for Chocolate Fudge Frosting:

  1. Prepare Frosting: In a medium bowl, combine all the frosting ingredients: powdered sugar, cocoa powder, softened butter or margarine, chocolate cream liqueur (or milk), and coffee (or milk).
  2. Beat Until Smooth: Using an electric mixer, start on low speed to avoid a cloud of powdered sugar, then gradually increase to medium-high. Beat until the frosting is completely smooth, creamy, and light, about 3-5 minutes. If the frosting is too thick, add a tiny bit more milk or coffee; if too thin, add a tablespoon more powdered sugar.
  3. Frost Cupcakes: Once the cupcakes are completely cooled to room temperature (this is crucial, as warm cupcakes will melt your frosting!), pipe or spread the decadent chocolate fudge frosting generously over each cupcake. Don’t forget those delightful sprinkles!

Pro Tips for Baking Perfect Chocolate Surprise Cupcakes

  • Ingredient Quality: Always use high-quality unsweetened chocolate and cocoa powder for the best flavor. Fresh buttermilk is essential for the cupcakes’ moist texture and subtle tang.
  • Room Temperature Matters: Ensure your butter/margarine for the frosting is truly at room temperature. This allows it to cream properly with the sugar and cocoa, resulting in a smooth, lump-free frosting.
  • Don’t Overmix: When combining wet and dry ingredients for the cupcake batter, mix only until just combined. Overmixing develops the gluten in the flour, leading to tougher, drier cupcakes.
  • Marshmallow Magic: For the marshmallow surprise, using large marshmallows creates a more dramatic, gooey center. If you want a more subtle surprise or are worried about them peeking out, mini marshmallows are an excellent alternative and require less “squishing.”
  • The Coffee Secret: Don’t skip the coffee in the frosting if you’re a coffee lover! It doesn’t make the frosting taste like coffee; instead, it deepens and intensifies the chocolate flavor, making it even more irresistible.
  • Cool Completely: Patience is key! Make sure your cupcakes are entirely cool before frosting. Warm cupcakes will cause the frosting to melt and slide off, creating a messy situation.
  • Storage: Store these cupcakes in an airtight container at room temperature for up to 3 days to maintain their freshness and moisture.

Frequently Asked Questions (FAQ) About Chocolate Surprise Cupcakes

Can I use regular milk instead of buttermilk?
While buttermilk adds a unique tang and moisture that’s hard to replicate, you can make a substitute. For 2/3 cup buttermilk, combine 2/3 cup regular milk with 2 teaspoons of white vinegar or lemon juice. Let it sit for 5-10 minutes until it slightly curdles, then use as directed.
What if I don’t have chocolate cream liqueur?
No problem! The recipe offers an excellent non-alcoholic alternative: chocolate syrup. This will still provide that extra depth of chocolate flavor without any alcohol.
My marshmallows aren’t melting enough. What can I do?
Ensure your cupcakes are still quite warm when you insert the marshmallows. If they cool too much, the marshmallows won’t melt properly. You can also briefly pop the marshmallow-filled cupcakes (without frosting) into a very low oven (around 200°F / 95°C) for a minute or two to help them soften, but watch them closely!
Can I make these ahead of time?
The cupcakes can be baked a day in advance. Store them unfrosted in an airtight container at room temperature. Frost them on the day of serving for the freshest taste and best appearance. The marshmallow center is best when slightly gooey, so serving them within 24 hours of assembly is ideal.
How can I make my frosting extra smooth?
Sift your powdered sugar and cocoa powder before mixing to eliminate any lumps. Also, ensure your butter is genuinely at room temperature – not too hard, not melted. Beat the frosting for a good 3-5 minutes until it’s light and fluffy.
