Ingredients for Smores Swiss Roll

Gathering the right ingredients makes all the difference in this campfire-inspired treat. Here’s exactly what you’ll need to create that perfect swirl of flavors:

3/4 cup all-purpose flour – spooned and leveled, not packed
1 teaspoon baking powder – make sure it’s fresh!
1/4 teaspoon salt – just enough to balance the sweetness
4 large eggs, room temperature – this is crucial for volume
3/4 cup granulated sugar – fine grain dissolves best
1 teaspoon vanilla extract – pure vanilla makes all the difference
2 tablespoons milk – whole milk gives the best texture
1 1/2 cups marshmallow fluff – packed lightly into measuring cup
1/2 cup heavy whipping cream – cold for whipping
1/4 cup mini chocolate chips – they distribute better than regular chips
1 cup semi-sweet chocolate chips – quality matters here
1/2 cup heavy cream – for that silky ganache
Toasted marshmallows – for garnish (I like to torch them right before serving)
Mini chocolate chips – extra for decoration
Chocolate syrup – just a drizzle makes it pretty

Pro tip: Measure everything before you start – it makes the whole process smoother when you’re in the baking zone!

Equipment You’ll Need

Don’t worry – you won’t need fancy gadgets for this Smores Swiss Roll! Just grab these basics:

10×15 inch jelly roll pan – the perfect size for rolling
Parchment paper – lifesaver for easy release
Stand mixer or hand mixer – for whipping eggs and cream
Silicone spatula – gentle folding is key
Small saucepan – for that dreamy ganache

That’s it! Now let’s get baking – the marshmallow filling is calling your name.

How to Make Smores Swiss Roll

Okay, let’s dive into the fun part! Making this Smores Swiss Roll is easier than you think – I’ll walk you through each step so you get that perfect swirl every time. Just follow along, and don’t worry if your first roll isn’t picture-perfect (mine definitely wasn’t!). The taste is what really matters, and trust me, this one delivers.

Preparing the Cake Base

First things first – preheat your oven to 350°F and line that jelly roll pan with parchment paper (leave some overhang – it’ll help later). Now, grab your eggs and sugar. Here’s my secret: whisk them for a good 5 minutes until they’re pale, fluffy, and form ribbons when you lift the whisk. This gives our cake that perfect lightness!

Next, gently fold in the flour mixture (I like to sift it right over the bowl to prevent lumps) along with the milk and vanilla. Go slow – we want to keep all that air we worked so hard to create. The batter should be smooth and pourable.

Rolling and Cooling the Cake

Here’s the trickiest part that’s actually not tricky at all – roll the cake while it’s still warm! As soon as it comes out of the oven (after about 10-12 minutes – edges should pull away slightly), grab the parchment edges and roll it up lengthwise like a sleeping bag. Let it cool completely like this – this “trains” the cake to hold its shape later.

Don’t panic if you hear a tiny crack – mine always does that! The marshmallow filling will hide any imperfections.

Making the Marshmallow Filling

While the cake cools, let’s make that dreamy filling. Whip the heavy cream to soft peaks (not stiff – we want it pillowy). Now gently fold it into the marshmallow fluff in batches. This keeps the filling light but still gloriously gooey. Stir in those mini chocolate chips last – they’re like little surprises in every bite!

Assembling the Smores Swiss Roll

Time for the magic! Carefully unroll your cooled cake (it’ll stay curled, don’t force it flat). Spread the marshmallow mixture evenly, leaving about a 1/2-inch border all around. Now roll it back up tightly, using the parchment to help guide you. No need to be perfect – rustic is charming!

Adding Chocolate Ganache

For the grand finale: heat the cream until just simmering, then pour over your chocolate chips. Let it sit for 2 minutes (patience!), then stir until silky smooth. Pour this luscious ganache over your roll while it’s still slightly warm – it’ll cascade beautifully down the sides. Top with toasted marshmallows and chocolate chips while the ganache is still soft.

Now the hardest part – waiting 30 minutes for everything to set before slicing! But oh, that first bite of chocolatey, marshmallowy perfection is worth it.

Tips for the Perfect Smores Swiss Roll

After making this dozens of times (and yes, learning from my mistakes!), here are my can’t-live-without tips:

Room temp eggs are non-negotiable – Cold eggs won’t whip up properly, and you’ll lose that perfect cake texture.
Toast marshmallows lightly – I use a kitchen torch just before serving for that authentic campfire char without making them rock-hard.
Let ganache cool slightly – Too hot and it’ll slide right off; too cold and it won’t pour smoothly. Aim for warm chocolate syrup consistency.
Roll with confidence! – Don’t overthink it. Even if it cracks a little (mine always does), the filling hides everything.

Remember – imperfect rolls taste just as amazing as picture-perfect ones!

Serving and Storing Smores Swiss Roll

Here’s how to make your Smores Swiss Roll shine! Right before serving, I love adding freshly toasted marshmallows on top – the slight char gives that authentic campfire flavor. A drizzle of chocolate syrup makes it extra pretty. For storage, just cover it loosely with plastic wrap and refrigerate for up to 3 days (though it never lasts that long in my house!). The marshmallow filling stays gloriously gooey, and the flavors actually deepen overnight. Serve slices straight from the fridge or let them sit out for 10 minutes if you prefer softer texture.

Smores Swiss Roll Variations

Want to mix things up? Try these fun twists on the classic:

Graham cracker crunch – Mix 1/4 cup crushed grahams into the marshmallow filling for that authentic s’mores texture
Dark chocolate ganache – Swap semi-sweet for dark chocolate chips for a richer, more grown-up flavor
Peanut butter swirl – Add a tablespoon of creamy PB to the marshmallow filling – trust me on this one!

The beauty of this recipe? It’s a perfect canvas for your favorite flavor combos!

Smores Swiss Roll FAQs

Got questions? I’ve got answers! Here are the most common things people ask me about this campfire-inspired dessert:

Can I use homemade marshmallow instead of fluff?
Absolutely! Just make sure it’s soft and spreadable – about the consistency of thick frosting. Homemade marshmallow gives an amazing fresh taste, though it might be slightly less stable than fluff. If using homemade, I’d suggest making the Swiss roll the same day.

Help! My cake cracked when rolling – what did I do wrong?
First, don’t panic! Small cracks are totally normal (happens to me too). The key is rolling while the cake is still warm but not hot. If it cooled too much, just microwave it for 5-10 seconds to make it pliable again. The marshmallow filling will hide any imperfections beautifully.

Can I make this ahead for a party?
You bet! The flavors actually improve after a few hours. Assemble the whole thing (including ganache) up to a day ahead, then just add fresh toasted marshmallows right before serving. Keep it refrigerated until about 30 minutes before your guests arrive.

What’s the best way to slice it cleanly?
Run your knife under hot water and wipe dry between each slice. The heat helps cut through the marshmallow filling cleanly. And don’t worry about perfect slices – rustic is part of the charm with this gooey marshmallow swirl cake!

Nutritional Information

Now, I’m no nutritionist, but I know some folks like to have a general idea of what they’re enjoying. Keep in mind these numbers are just estimates – the exact nutrition will depend on your specific ingredients and brands. That marshmallow fluff might be slightly different than mine, or maybe you went heavier on the chocolate chips (no judgment here!).

This Smores Swiss Roll is definitely an indulgent treat – we’re talking rich chocolate, gooey marshmallow, and all those campfire-inspired flavors we love. It’s perfect for special occasions when you want to treat yourself and your loved ones. As my grandma used to say, “Life’s too short to skip dessert!” Just enjoy each delicious bite.
