A chocolatey and delicious, no-bake Oreo rocky road treat full to the brim with chocolate, Oreos, marshmallows and more! Quick, easy & heavenly.

Rocky road

Rocky road has always held a special place in my baking heart, and every time I create a new variation, I fall a little more in love with it. This version came about after a wave of Oreo cravings and a strong urge to make something no-bake and ridiculously easy. With a bit of experimenting, this white-chocolate-based masterpiece became a new favourite in my kitchen.

Oreo recipes are always among the most popular on my blog, so it felt only right to give rocky road the Oreo treatment it deserved – it’s crazy how popular they are. For example my Oreo millionaires, Oreo drip cake, Oreo cheesecake and my Oreo NYC cookies. Even my Oreo ice cream. it’s clear that you all adore these iconic black-and-white biscuits as much as I do. Bringing them into a no-bake traybake felt natural, fun, and honestly… very necessary.

This recipe also serves as a reminder of how much joy there is in simple, throw-together treats. Whenever I make rocky road I get that same nostalgic hit of mixing bowls full of colourful bits and pieces. There’s something wonderfully chaotic about it, and that’s exactly why it always turns out delicious.

The chocolate base

I’ve made a few versions of this recipe, and decided the white chocolate worked best. Not only can you actually see the Oreos more (it looks far nicer) but I like the flavour combination of it. It’s also nicer to have a different base compared to my other recipes such as my Rocky Road, and Easter Rocky Road. White chocolate also gives this rocky road a brighter, more eye-catching look compared to traditional milk or dark chocolate versions. It melts smoothly when gently heated, making it ideal for binding everything together without any fuss.

White chocolate is known for being more temperamental when combined with extra fats, so keeping things simple genuinely gives a better result. It also means fewer ingredients and quicker assembly time, which is always a win. Using good quality chocolate is key to achieving the look you are after, I use this white chocolate.

If you prefer a richer, deeper flavour, the recipe can absolutely be adapted using milk or dark chocolate. For these variations, adding butter and golden syrup creates a softer, fudgier mixture that sets beautifully. However, for this specific Oreo version, the white chocolate truly makes the flavours shine.

Oreo, marshmallow & mix-ins

The heart of any rocky road is the delicious combination of treats mixed into the chocolate, and this one is absolutely packed. Quartered Oreos bring that classic crunchy bite, swirls of cream filling, and pops of black-and-white colour throughout every slice. They soften slightly as they chill but still keep enough structure to give every mouthful texture.

Mini marshmallows add that essential chewy, sweet contrast that rocky road is known for. Because they’re small, they distribute evenly and catch chocolate between their gaps, giving irresistible pockets of squishy goodness. They also look adorable dotted through the white chocolate base, adding colour without overpowering the Oreos.

The glacé cherries and pistachios introduce something a little extra for those who love a mix of textures and flavours. The cherries bring sweetness and colour, while the pistachios add crunch and a soft nuttiness that complements everything else. These additions are completely customisable, but together they create a rocky road that tastes layered, interesting and utterly moreish. 

Melting and setting

Because this is a no-bake recipe, the method is wonderfully simple and perfect for any skill level. Gently melting the white chocolate is the most important step, as slow, low heat prevents the chocolate from seizing. Whether you use a double boiler or the microwave, taking your time ensures a smooth, glossy base ready to coat all the mix-ins.

Once melted, the fun really begins as everything gets folded into the warm chocolate. Adding the marshmallows, Oreos, pistachios and cherries at once helps them distribute evenly, creating a beautifully varied mix. Holding back a handful of each ingredient means you can finish the top with a decorative layer that looks just as good as it tastes.

After pouring the mixture into the lined tin, lightly spreading it ensures you get an even thickness throughout. Topping it with the reserved pieces not only creates visual appeal but also hints at what’s hidden inside. A short chill in the fridge sets everything perfectly, giving you rich, firm slices that are incredibly satisfying to cut.

Decoration and serving

Decorating rocky road is always simple but effective, especially when you’ve saved a few of each mix-in to scatter across the top. The contrast of white chocolate, dark Oreo pieces, bright cherries and green pistachios makes the whole tray look vibrant and inviting. Even without intricate piping or drips, this traybake still makes a stunning impression.

Serving couldn’t be easier, as this treat slices beautifully once chilled. You can cut generous squares for sharing, or smaller bites if you’re serving at a party or gathering. Because of the rich chocolate and chunky filling, even a small piece delivers big flavour and plenty of texture.

If you’re in the mood to customise, rocky road is one of the most adaptable recipes you can make. Try swapping pistachios for other nuts, adding dried fruit, or using flavoured Oreos for something playful. The base method stays the same, letting you personalise it every time you make it. 

Tips & tricks

• If you would like to make this with milk or dark chocolate, you can add in 100g of butter and 100g of golden syrup when you are melting the chocolate and it’ll make it delicious. However, I find this can be a little risky (it can split/curdle easily) and too sweet for the white chocolate so I leave it as just chocolate when using white.
• I use this white chocolate
• I use this 9″ traybake tin
• You can easily half the recipe for less, but these are so moreish you will want the large piece, trust me.
• I used a mix of regular Oreos and Birthday Cake flavour Oreos in this, along with the pistachios, cherries and mini marshmallows. All of the filling types are optional, but I adore this combination with the Oreos.
• This will last in the fridge for 2-3 weeks in an airtight container, or you can freeze it for up to 3 months.
