Acai Berry Cheesecake (Raw, Frozen)
with a Toasted-Nut Base, Cashew-Coconut Cream & Amazonian Acai
A frozen slab of bruise-purple açai and cashew-coconut cream over a toasted-nut crumb, slicing like semifreddo — cold, dense, tannic with dark berry, and barely sweet.

Adapted from Gaz Oakley (Avant-Garde Vegan), whose açai cheesecake is the blueprint here — a frozen cake that never sees an oven. It earned a place in the book as the high-summer closer, the night the cabin is too hot to bake and someone hauls a purple-black cake out of the chest freezer at the far end of the porch. The açai stains it the deep bruise-color of the berries themselves, and it slices like a semifreddo — cold, dense, barely sweet. (The porch-freezer framing is our own; the recipe and method are Gaz's, reconstructed from his published one.)

The Tools
- Kitchen scale — Nut and oil weights decide the set — weigh them, don't scoop
- Food processor (base) — Right tool for a pressable crumb; a blender over-works the nuts to butter
- High-speed blender (Vitamix / NutriBullet-class, filling) — A weak blender leaves the cashews gritty and the cake never turns silky
- 7-inch springform pan (or 8 silicone dariole moulds) — Removable base is what makes the frozen cake come out clean
- Parchment round (pan base)
- Mixing bowl (soak the cashews)
- Fine-mesh sieve or colander (drain cashews)
- Small saucepan or heatproof bowl (melt coconut oil)
- Offset spatula or the back of a spoon (press base, smooth top)
- Measuring spoons
- Electric kettle (optional) — Boiling water for the quick-soak and the hot-cloth unmould
- Clean tea towel (hot-cloth unmould)
- Thin-bladed knife (serving) — Run it under hot water and wipe between cuts

Toasted-Nut Base
Why this works A pressed raw crumb, not a baked crust — the structure comes from fat, not gluten or eggs. Coconut oil is solid below about 76°F (24°C), so once the cake goes back in the freezer the oil recrystallizes and cements the ground nuts into a sliceable slab; the agave adds tack and a faint chew, and the tablespoon of peanut butter is doing real work — its emulsified fat-and-protein is the glue that lets the crumb hold a shape under the knife. The one trap is the food processor: nuts are ~50-75% oil by weight, and if you run the machine past a coarse, clumping crumb the cells rupture and weep oil, turning the base greasy and dense. Pulse, stop early, and judge it by squeeze — it should hold a pinch, not smear. A pinch of salt pulls the nut sweetness forward and cuts the coconut fat.
- 1 1/2 cups (125g) Ground almonds (almond flour/meal) 125 g
- 1/2 cup (70g) Macadamia nuts 70 g — Raw; their high fat makes the base short and buttery
- 1/2 cup (40g), plus extra for topping Pecans 40 g
- 3 tbsp (63g) Agave nectar 63 g — Light or amber; the syrup is a binder as much as a sweetener
- 3 tbsp (42g), melted Coconut oil 42 g
- 1 tbsp (16g), smooth natural Peanut butter 16 g — Natural (only peanuts + salt); the sugar-loaded kind makes the base cloying
- 1 generous pinch Fine sea salt
-
Line the pan 3 min hands-on
Drop a parchment round onto the springform base, clamp the ring shut over it, and set the pan on a tray that fits your freezer.
-
Pulse to a crumb 4 min hands-on
All base ingredients into the food processor. Pulse in short bursts, scraping down once, until the mixture is a damp, sandy crumb that clumps when pressed.
Look for Squeeze a pinch: it should hold together like wet sand. Still powdery and loose means a few more pulses.
Take care Run it past clumping and the nuts weep oil into a greasy paste — you cannot un-blend it. Pulse, check, stop early. -
Press and compact 5 min hands-on
Tip the crumb into the pan and press it into an even ~1cm layer with an offset spatula or a flat-bottomed glass, driving out air so it slices clean. Press the edges as firmly as the center.
Look for A smooth, compact, gapless floor — no loose crumbs, no thin spots at the rim.
Take care A loosely pressed base shatters into gravel under the knife. Lean on it. -
Freeze firm 1 min hands-on · 15 min wait
Freeze flat while you make the filling — at least 15 minutes, longer is fine.
When it goes wrong
| Problem | Cause | Fix |
|---|---|---|
| Base is oily and dense | Food processor run too long; nuts released their oil | No fix once weeping; next time pulse to a clumping crumb and stop |
| Base crumbles when sliced | Under-pressed or under-chilled | Press harder next time; always cut the cake cold, straight from the freezer |
| Crumb won't hold together at all | Too dry — nuts too coarse or short on syrup/oil | Pulse in an extra teaspoon of melted coconut oil until it clumps |
Cashew-Coconut-Acai Filling
Why this works There is no cheese and no dairy here — the cheesecake illusion is built from three levers. First, soaked cashews: soaking hydrates the nut and softens its cell walls so a high-speed blender can shear them into a silk-smooth cream instead of grit; skip the soak and no amount of blending gets there. Second, full-fat coconut milk and one frozen banana give body, a mild tang, and enough water to move the blade. Third — and this is the whole game — a full cup of melted coconut oil, streamed in last. Coconut oil is ~90% saturated fat and sets hard below 76°F (24°C); dispersed evenly through the filling and then frozen, it crystallizes into a fat network that holds the cake firm and lets it slice. That is why it goes in fully melted and fully emulsified: streamed into a running blender it disperses into microscopic droplets, but dumped onto a cold filling it seizes into brittle white shards that never smooth out. This is a frozen dessert set by fat, not a baked custard set by egg or a mousse set by gelatin — so it must be served just-thawed at the edge. The açai brings the color, the tannic dark-berry flavor, and the antioxidant load; it does almost nothing structural.
- 1 1/4 cups (170g), soaked Raw cashews 170 g — Raw and unsalted; roasted cashews won't cream
- 1 cup (240ml, ~218g), melted Coconut oil 218 g — Melted to just-liquid and no hotter — this is the setting agent, don't skimp
- 1 medium (~118g), in chunks Frozen banana 118 g — Spotty-ripe before freezing; green banana reads starchy and flat
- 1 tin (400ml), shaken Full-fat coconut milk 400 g — Full-fat only — light coconut milk is mostly water and won't set rich
- 6 tbsp (120g) Maple syrup 120 g — Pure, dark for depth
- 1 pinch Fine sea salt — A frozen filling with no salt reads flat — a pinch lifts the sweetness and the berry
- 2 tsp (9g) Vanilla extract 9 g
- 4 packs (~100g each) Frozen açai berry sachets (Sambazon, unsweetened) 400 g — Break the frozen packs against the counter before they go in
-
Soak the cashews 3 min hands-on · 25 min wait
Cover the cashews with just-boiled water and quick-soak 20-30 minutes (or cold-soak 4 hours to overnight, refrigerated). Drain well and shake dry.
Look for A soaked cashew crushes to paste between two fingers with no chalky core.
Take care Under-soaked cashews stay gritty and no blender saves them once the cake is frozen. -
Melt the coconut oil 2 min hands-on
Melt the coconut oil gently — warm water bath or 20-second microwave bursts — to just-liquid, around 90-100°F (32-38°C). Set it somewhere warm so it stays pourable.
Look for Clear and pourable with no cloudy solids left, but still cool enough to hold a fingertip in — barely warm, never hot.
Take care Hot oil (over ~120°F) shocks the cold filling and can split it. Just-melted and no hotter. -
Blitz the filling smooth 6 min hands-on
Drained cashews, banana, coconut milk, maple, vanilla, salt and açai into the high-speed blender. Run on high, scraping down twice, 60-90 seconds — past thick, past chunky, all the way to pourable silk. Taste it now, before the oil goes in and before it ever freezes: it should read a shade sweeter and more seasoned than you want at room temperature, because cold blunts both sweetness and salt. Nudge maple or salt up until it does — this is your last chance to fix the flavor.
Look for A glossy, deep-violet cream with zero grain — rub a drop between finger and thumb and feel nothing but smooth.
Take care Stop short and you set grit into the cake permanently. Blend longer than you think, and let the mixture warm from the friction so it's no longer ice-cold before the oil goes in. -
Emulsify in the oil 3 min hands-on
With the blender running on low, pour the melted coconut oil into the filling in a slow, steady stream, then run 15-20 seconds more until fully incorporated and a shade glossier.
Look for The cream thickens slightly and turns satiny — no oil slick riding on top, no pale flecks in the purple.
Take care Cold filling plus a fast pour makes the oil seize into white shards that never smooth out. Filling not fridge-cold, oil just-liquid, slow stream, motor running. -
Pour over the base 4 min hands-on
Pour the filling over the frozen base. Tap the pan on the counter a few times to level it and knock out air pockets, then smooth the top with the offset spatula.
Look for A flat, glassy purple surface level with — or just below — the pan rim.
-
Freeze solid 1 min hands-on · 4 h wait
Freeze flat and undisturbed at least 4 hours, ideally overnight, until frozen through.
Look for Press the center: it should feel rock-solid, not tacky. Any give and it will slump when unmoulded.
-
Hot-cloth unmould 5 min hands-on
Boil the kettle, soak a tea towel in the hot water and wring it out. Wrap it around the outside of the pan ring for 10-15 seconds to melt a thin film of oil at the wall, then release the springform. If using silicone moulds, flex and push from the base.
Look for The ring lifts away with the cake wall smooth and intact, not torn.
Take care Too long against the hot cloth and the edge melts and rounds off. A few seconds at a time; re-wrap if it resists. -
Temper and decorate 5 min hands-on · 20 min wait
Sit the cake out 20 minutes before serving so the edge softens from freezer-hard to sliceable. Decorate in that window.
Look for A knife tip meets faint resistance, like firm ice cream — not a brick, not a puddle.
Take care Overshoot the window in a warm room and the coconut oil melts and the cake slumps. Serve at the just-thawed edge; return leftovers to the freezer fast.
When it goes wrong
| Problem | Cause | Fix |
|---|---|---|
| Grainy, sandy texture | Cashews under-soaked or filling under-blended | No rescue once frozen; next time soak fully and blend to true silk before the oil goes in |
| Hard white flecks through the filling | Coconut oil added too cold or too fast, or filling was ice-cold | Re-melt only if caught before freezing; stream just-liquid oil into a not-cold filling on a running motor |
| Cake slumps or won't unmould | Under-frozen, or tempered too long | Freeze a full 4 hours minimum; unmould straight from the freezer, then temper only 20 minutes |
To the Table
Unmould straight from the freezer and lift the cake, still on its springform base, onto a chilled board or cake stand.
Crown it while it tempers: fresh berries piled off-center, a spoonful of frozen açai broken into shards, a scatter of chopped pecans, and freeze-dried berries for crackle.
Tuck two or three small mint leaves against the fruit for green against the bruise-purple — a few leaves, not a bush.
Slice with a thin blade run under hot water and wiped dry between every cut; press straight down, don't saw.
Serve within the 20-minute window while the edge is just-thawed and the center still holds an ice-cream chill. Any leftover goes back to the freezer immediately.

A genuinely rich slice, not a light one — a full cup of coconut oil plus 235g of base nuts and 170g of cashews put nearly all the calories in fat, and the fat is what freezes the cake solid. Cut smaller than you think. High-FODMAP as written — the cashews and agave carry most of the load — but the substitutions rebuild a genuinely low-FODMAP slice (macadamias for the cashews, maple for the agave, pecan-macadamia crumb for the almond flour); hold it to one slice, because FODMAP stacking is real. A nut-free build on sunflower seeds and coconut is below too — earthier, still this cake. Vegan and gluten-free as written; the only animal-adjacent flag is the trace alcohol in real vanilla extract, swappable below.
Words We Used
- Açai
- A deep-purple Amazonian palm berry, sold frozen as unsweetened puree packs. Tastes of tannic dark berry and unsweetened chocolate; it colors and flavors the cake but doesn't set it.
- Quick-soak
- Covering nuts in just-boiled water for 20-30 minutes to hydrate and soften them fast — the shortcut for the traditional hours-long cold soak that makes cashews blend silky.
- Emulsify
- Dispersing a fat evenly through a water-based mixture so it stays one smooth cream — here, streaming melted coconut oil into the running blender so it never seizes.
- Temper (frozen dessert)
- Letting a frozen cake sit out briefly so the edge softens from rock-hard to sliceable without melting the center — the 20-minute window before serving.
- Springform pan
- A round pan with a latching ring that releases from its base, so a delicate frozen cake comes out sides-first without being flipped.
