Some desserts look like they took all day and hide the fact that they took barely half an hour of actual work. This is one of them. A crunchy Oreo crust, a thick coconut-cashew filling studded with cookie chunks, and a glossy dark chocolate ganache on top. It slices like a real ice cream cake, with no ice cream machine and no oven.
I make this when I need a dessert that can be finished days ahead, like birthdays, summer barbecues, or holiday tables where half the guests are dairy-free and the other half don’t notice. The freezer does the heavy lifting, so on party day you just slice and serve.
The trick is the filling. Blending soaked cashews with chilled coconut cream gives a texture that is rich and scoopable without being icy or greasy. It tastes like cookies and cream, and nobody will ask what’s missing.
Why You’ll Love This Recipe
- Truly no bake. You need a blender, a freezer, and a springform pan. Nothing else.
- Make-ahead friendly. It keeps in the freezer for up to 2 weeks, so it’s ready when you are.
- Creamy, not icy. Cashews and coconut cream freeze into a smooth, sliceable texture.
- Fully vegan. It’s dairy-free and egg-free, and it needs no specialty vegan ingredients beyond vegan butter and dairy-free dark chocolate.
- Serves a crowd. One 9-inch cake makes 12 generous slices.
Ingredient Notes
Oreo cookies. You’ll use about 46 in total: 24 for the crust, 16 chopped into the filling, and 12 for the topping (6 crushed, 6 halved). Standard Oreos contain no animal ingredients, but formulations vary by country, so check your label. For gluten-free, swap in gluten-free chocolate sandwich cookies.
Raw cashews. These are what make the filling silky. Soak them in hot water for 30 minutes, then drain well. Skipping the soak leaves you with a grainy filling.
Full-fat canned coconut milk. Two cans, chilled overnight, at least 12 hours. Don’t shake them. The thick cream rises and solidifies, and that’s the part you scoop off. Avoid “light” coconut milk, and if you can, choose a brand without guar gum, since it separates more cleanly.
Vegan butter. It binds the crust. Use a stick-style or block vegan butter, not a soft tub spread, which can be too wet.
Dark chocolate. Check that it’s dairy-free. A bar around 60 to 70 percent cocoa gives a ganache that’s bittersweet enough to balance the sweet filling.
Nut-free? Replace the cashews with an extra 1/2 cup (120 ml) of solid coconut cream and 1/2 cup (120 g) of nut-free vegan cream cheese. The texture will be a little less rich but still good.
Step-by-Step Instructions
Start with the crust, and chill it
Line the bottom of a 9-inch (23 cm) springform pan with parchment and lightly grease the sides. Crush 24 Oreos into fine crumbs in a food processor, or seal them in a zip-top bag and go at them with a rolling pin. Fine crumbs matter, because chunks make a crust that crumbles when you slice. Stir in the 4 tablespoons of melted vegan butter until the mixture looks like wet sand and holds together when pinched.
Press the crumbs firmly into the base and about 1 inch (2.5 cm) up the sides. Use the flat bottom of a glass to pack them tight, which is the difference between a crust that holds and one that falls apart. Freeze it for 15 minutes while you make the filling. A cold crust also keeps the filling from sinking into it.
Blend the filling until it’s completely smooth
Open your chilled cans and scoop off only the thick, solid cream. Save the thin liquid underneath, because you’ll need 1/2 cup of it for the ganache. Add the cream to a high-speed blender with the drained cashews, maple syrup, powdered sugar, vanilla, and salt.
Blend on high for 1 to 2 minutes, stopping to scrape down the sides. You’re done when it looks like thick, glossy whipped cream and you can’t feel any grit when you rub a little between your fingers. If you see tiny flecks, keep blending. Grit now means a grainy cake later.
Fold in the cookies, then fill and freeze
Pour the filling into a large bowl and fold in 16 coarsely chopped Oreos with a spatula. Fold gently and don’t stir hard, or the cookies will bleed gray into the filling. Chop them into pieces roughly the size of a chickpea, so every slice gets crunch without big hollow pockets.
Pour the filling over the chilled crust, smooth the top, and tap the pan gently on the counter to release air bubbles. Cover loosely with foil or plastic wrap and freeze for at least 4 hours. The cake is ready when it feels firm all the way to the center, not just on the surface.
Make the ganache and let it cool
Put 6 ounces of finely chopped dark chocolate in a heatproof bowl. Warm 1/2 cup of the reserved coconut milk (stir it first, since it will have separated) until steaming but not boiling, then pour it over the chocolate. Wait 2 minutes so the heat can melt the chocolate evenly, then stir until glossy and smooth.
The important part is the cooling. Let the ganache sit 10 to 15 minutes until slightly thickened but still pourable. Pour hot ganache onto the frozen cake and it will melt the surface and slide off in a thin, streaky layer.
Top it and freeze again
Pour the ganache over the frozen cake and spread it to the edges. Work fast and sprinkle on the crushed Oreos right away, then arrange the halved cookies around the top. The ganache firms up quickly on the cold surface, and toppings only stick while it’s still soft. Freeze another 2 hours, until the ganache is set.
Slice it cleanly
Let the cake sit at room temperature for 10 to 15 minutes before serving. Run a warm knife around the edge, then release the springform. For neat slices, dip a sharp knife in hot water, wipe it dry, and cut. Repeat between every slice.
Pro Tips
- Chill the cans for a full 12 hours. A short chill leaves you with soft, watery cream, and the filling won’t set as firmly.
- Warm your knife, don’t just wet it. Hot water and a dry blade give you clean, bakery-style slices instead of cracked chocolate.
- Don’t skip the pre-freeze of the crust. It sets the base and helps the layers stay separate and distinct.
- Measure the ganache by feel. If it’s still warm to the touch, wait. If it thickens too much, warm it for 5 to 10 seconds and stir.
Best tip: Let the ganache cool until it just starts to thicken before pouring. Poured hot, it melts the frozen surface and slides right off.
Storage & Reheating
Freeze the cake tightly covered, either in the pan or wrapped after slicing, for up to 2 weeks. For grab-and-go treats, freeze individual slices on a tray until solid, then wrap each one and stack them in a container.
There’s no reheating. This is served cold. Just let the cake or slice sit at room temperature for 10 to 15 minutes before serving so the filling softens to a creamy, scoopable texture. Don’t refreeze a cake that has fully thawed, because the texture turns icy.
Variations & Substitutions
- Peanut butter swirl: Drizzle 1/4 cup of melted peanut butter over the filling before the final freeze and drag a knife through it.
- Mint chocolate: Add 1/2 teaspoon of peppermint extract to the filling and use mint-flavored sandwich cookies for the topping.
- Coffee lovers: Stir 1 tablespoon of instant espresso powder into the filling.
- Gluten-free: Use gluten-free chocolate sandwich cookies throughout.
- Nut-free: See the ingredient notes above for the coconut cream and vegan cream cheese swap.
- Less sweet: Reduce the maple syrup to 1/3 cup, though the filling will freeze slightly firmer.
Frequently Asked Questions
Do I really need to soak the cashews?
Yes. Soaking softens them so they blend smoothly. Skip it and you’ll end up with a grainy filling, even in a strong blender.
Can I make this without a high-speed blender?
You can, but soak the cashews for a couple of hours instead of 30 minutes and blend longer, scraping often. A standard blender will usually leave a bit more texture.
Why is my filling icy or crumbly instead of creamy?
Most often the coconut cans weren’t chilled long enough, or “light” coconut milk was used. Full-fat milk chilled at least 12 hours gives the richest, smoothest result.
How do I get clean slices?
Let the cake sit for 10 to 15 minutes, then use a sharp knife dipped in hot water and wiped dry between cuts.
Can I make this ahead for a party?
Yes, that’s what it’s built for. Make it up to 2 weeks ahead and keep it well covered in the freezer.
Serving Suggestions
Serve slices with fresh raspberries or strawberries, since the tartness cuts through the richness. A drizzle of extra warm ganache or a dollop of coconut whipped cream on the side also works well. For a dessert spread, pair it with hot coffee, espresso, or a cold glass of oat or almond milk.
