These no-bake truffles start with crushed Oreos and mascarpone rolled into bite-size balls, then get a double coating: white chocolate mixed with toasted hazelnuts, finished with a drizzle of dark chocolate for contrast. There’s no oven involved and no stovetop cooking beyond melting chocolate in the microwave, just a food processor and a stretch of time in the fridge to let everything firm up. Most of the 30 minutes of prep is hands-on work, rolling and dipping, while the chilling in between happens on its own.
The hazelnuts do double duty here, folded right into the white chocolate coating for crunch and scattered on top before it sets, so every bite carries a bit of that toasted, nutty flavor alongside the cookies-and-cream base. If you like layering crushed cookies into no-bake desserts, our Oreo cheesecake uses the same crumb base, and our chocolate truffle tart leans on the same rich, glossy coating.

This batch makes about 20 truffles, plenty for a holiday cookie tray, a bake sale, or a gift box lined with parchment paper. They hold their shape well at room temperature for serving, which makes them easier to transport than anything with a soft filling that needs to stay cold the whole way there.
Ingredients
- 1 package Oreos (any flavor; double-stuffed or regular)
- 8 oz mascarpone cheese
- 6 oz high-quality white chocolate, chopped (for dipping)
- 12 oz semisweet chocolate, chopped (for garnish)
- 6 oz hazelnuts, toasted and finely chopped (for mixing, dipping, and garnish)
- Optional toppings: sprinkles, additional crushed cookies
Instructions
- Make the truffle base: Crush the Oreos in a food processor until they turn into fine crumbs. Add the mascarpone cheese and blend until the mixture is well combined and forms a sticky dough. Stir in half of the finely chopped hazelnuts by hand so they’re distributed evenly throughout.
- Shape and chill: Roll the mixture into 1-inch balls and arrange them on a plate or tray lined with parchment paper. Freeze for at least 30 minutes, until firm enough to hold their shape once dipped.
- Dip in hazelnut white chocolate: Melt the white chocolate in a microwave-safe bowl in 30-second bursts, stirring between each, until completely smooth. Stir in half of the remaining chopped hazelnuts. Working one truffle at a time, dip each ball with a fork until fully coated, then set it on a wax-paper-lined baking sheet. Refrigerate for at least 10 minutes to set the coating.
- Garnish with dark chocolate: Melt the semisweet chocolate the same way, in 30-second microwave bursts, stirring in between. Drizzle it over the chilled truffles with a fork for a two-tone finish. Sprinkle the last of the chopped hazelnuts over the top while the chocolate is still wet so it sticks.
- Set and serve: Return the truffles to the refrigerator for another 10 minutes, until the dark chocolate is fully set. Serve them straight from the fridge, or let them sit at room temperature for a few minutes first if you prefer a softer bite.
Tips for the Best No-Bake White Chocolate Oreo Truffles with Hazelnuts
- Freeze the truffle balls before dipping, not just chill them. A firm, cold center holds its shape in warm melted chocolate, while a soft one can start to fall apart on the fork halfway through dipping and leave you fishing crumbs out of the coating.
- Keep every bowl and utensil bone dry before you melt chocolate. Even a few drops of water can make it seize into a grainy, unworkable clump instead of staying smooth, and once that happens there’s no whisking it back to normal.
- Use real chocolate bars meant for melting instead of chocolate chips if you can. Chips are formulated to hold their shape rather than melt smoothly, and it shows in the finished coating as a slightly duller, thicker layer instead of a glossy shell.
- Toast the hazelnuts yourself if you’re starting from raw nuts. A few minutes in a dry skillet or a 350°F oven brings out a deeper, nuttier flavor than skipping that step, and it also loosens the papery skins so they rub off easily.
- Work with a few truffles at a time when dipping. Melted chocolate firms up fast at room temperature, and a whole batch left sitting out too long turns thick and hard to coat evenly, forcing you to reheat it partway through.
- Swap the hazelnuts for chopped pecans or almonds if that’s what you have on hand. The texture holds up the same way, just with a different flavor note, and either one still gives the coating some crunch against the soft filling.
- If your mascarpone mixture feels too soft to roll into balls, chill it in the bowl for 15 minutes before you start shaping. A cold, firm dough is much easier to portion evenly than one that’s sticking to your hands.
Storage
Store the truffles in an airtight container in the refrigerator, where the mascarpone filling keeps them fresh for about a week. Layer them between sheets of parchment or wax paper if you’re stacking more than one row, since the chocolate coating sticks to itself easily and can pull apart when you separate the layers. According to University of Nebraska-Lincoln Extension’s food safety guidance, perishable foods made with dairy shouldn’t sit out at room temperature for more than 2 hours, so get any truffles you’re not serving right away back in the fridge rather than leaving the whole tray out. For longer storage, freeze them in a single layer on a tray first so they don’t stick together, then transfer to a freezer-safe container for up to 2 months once solid. Thaw them overnight in the refrigerator rather than on the counter, so the chocolate coating doesn’t sweat and turn dull, and let them sit out for 10 to 15 minutes before serving if you want the filling soft again.
FAQ
Can you freeze white chocolate Oreo truffles?
Yes, and they freeze well thanks to the sturdy chocolate shell around the filling. Freeze them in a single layer on a tray until solid, about 2 hours, then transfer to a freezer-safe container or bag for up to 2 months. Thaw them in the refrigerator overnight instead of on the counter, since a fast thaw at room temperature can cause condensation that dulls the chocolate coating and makes it look streaky.
Why did my white chocolate seize instead of melting smooth?
White chocolate seizes when even a small amount of water gets into the bowl, whether from a wet spoon, condensation dripping off the lid, or steam from a nearby pot. Make sure your bowl and utensils are completely dry before you start, and melt it in short 30-second bursts in the microwave rather than all at once so it doesn’t overheat and separate. If it does seize, whisking in a small spoonful of warm cream can sometimes smooth it back out.
Can you make these truffles without a food processor?
Yes, put the Oreos in a sealed zip-top bag and crush them with a rolling pin until they’re fine crumbs. It takes a little more effort to get an even texture than a food processor does, since you have to work in batches and check for larger chunks, but the truffles turn out the same either way once everything is mixed together.
What can you use instead of mascarpone cheese?
Cream cheese is the easiest swap and works in the same amount called for in the recipe. It has a slightly tangier flavor than mascarpone, but it holds the truffle base together just as well and rolls into balls the same way. Let it soften at room temperature first so it blends smoothly with the crushed cookies instead of leaving small lumps.
How far ahead can you make Oreo truffles?
You can make them up to a week ahead and keep them refrigerated in an airtight container until you’re ready to serve. If you want to get further ahead of a party or holiday, freeze them instead and just pull out what you need the night before, letting them thaw in the fridge so the chocolate coating stays glossy.
