How to Make White Christmas Marshmallow Rice Bubble Slice Recipe
Step 1: Melt Butter and Marshmallows Gently
Start by lining a 17 x 27cm baking tray with baking paper—that step makes cleanup and removal a breeze later on. Place 80g of butter in a large saucepan over low heat and let it melt slowly. Once melted, add 180g of white marshmallows and keep stirring gently until they’re fully melted and combined with the butter. Trust me, low and slow is key here to avoid burning or clumping, so patience is your friend.
Step 2: Mix in Vanilla and Rice Bubbles
Once your marshmallow mixture is perfectly smooth, stir in 1 teaspoon of vanilla essence for that lovely aromatic hint. Then, promptly add 4 cups of rice bubbles, folding them in quickly but gently so every crisp little puff gets coated before the mixture cools. You don’t want the marshmallows to harden before mixing everything together, so move swiftly!
Step 3: Press Into the Tray and Add Toppings
Tip the sticky rice bubble mix into your lined tray. Using the back of a dessert spoon, press it firmly and evenly to the edges—this step ensures the slice holds together well without being crumbly. Then drizzle 75g of melted white chocolate over the top and scatter Christmas sprinkles and M&Ms generously. This is where the magic really happens, and my family honestly gets so excited at this stage!
Step 4: Chill and Slice
Pop the tray in the fridge for at least 2 hours, or even better overnight. This chilling time helps the slice set firm so you can cut neat squares. When it’s ready, slice up and place your pieces in an airtight container to keep the freshness locked in.
Pro Tips for Making White Christmas Marshmallow Rice Bubble Slice Recipe
- Don’t Rush the Melting: I learned the hard way that melting marshmallows too quickly can cause them to seize or burn, so keep the heat low and stir often.
- Work Fast with the Rice Bubbles: Once marshmallows are melted, you’ve got a small window before they set, so adding and mixing your rice bubbles quickly is key.
- Press Firmly into the Tray: Pressing well means the slice holds together perfectly when cut, no crumbling mess on your hands!
- Chill Overnight for Best Texture: While two hours works, leaving it overnight really helps the slice firm up, making slicing and handling easier.
How to Serve White Christmas Marshmallow Rice Bubble Slice Recipe
Garnishes
I usually keep it simple by piling on classic Christmas sprinkles and bright M&Ms for that cheerful look. Sometimes I add a few crushed peppermint bits for an extra festive touch—it complements the sweetness perfectly and adds crunch.
Side Dishes
This slice stands beautifully on its own, but I occasionally serve it alongside a hot cuppa tea or a glass of chilled milk. For parties, it pairs nicely with other no-bake treats or a cheese platter to balance sweetness.
Creative Ways to Present
For Christmas, I like to cut the slice into festive shapes using cookie cutters—stars and trees are my favorites—and then arrange them on a pretty platter with holly leaves or edible glitter for extra sparkle. It’s such a crowd-pleaser and looks gorgeous on the dessert table.
Make Ahead and Storage
Storing Leftovers
I keep leftover slices in an airtight container at room temperature or in the fridge if the room is warm. They stay fresh and chewy for up to 5 days, making them perfect for quick snacks or lunchbox treats during the holidays.
Freezing
I’ve frozen these slices wrapped tightly in plastic wrap and then foil, and they thaw beautifully without losing that delightful chewy texture. Just defrost them at room temperature before slicing to enjoy fresh-tasting treats anytime.
Reheating
This isn’t a recipe that needs reheating, but if your slice feels a little too firm after chilling, I like to leave it out for 15 minutes before serving to soften slightly. That way, it’s soft and chewy with every bite.
FAQs
-
Can I use other types of cereal instead of rice bubbles?
Absolutely! While rice bubbles provide a nice light crunch, puffed wheat or cornflakes can work too. Just keep in mind they may change the texture slightly, so choose a cereal you love and that holds up well to sticky marshmallows.
-
Is this slice gluten-free?
Rice bubbles themselves are usually gluten-free, but you should check the packaging to be certain, as some brands may have additives. Using gluten-free marshmallows and certified gluten-free cereals can make this slice safe for gluten-sensitive folks.
-
How do I prevent the marshmallows from sticking to my hands?
Once the slice is pressed and cooled, spraying your hands lightly with cooking spray or lightly buttering your spoon and hands helps prevent stickiness when cutting and handling.
-
Can I add nuts or dried fruit to this recipe?
Yes! Adding chopped nuts or dried fruit can give lovely texture and flavor contrasts. Just mix them in with the rice bubbles before pressing into the tray to distribute evenly.
