Dairy-Free Low-Carb Peanut Butter Pie
I test dessert recipes obsessively so you don’t have to. This Dairy-Free Low-Carb Peanut Butter Pie is one I keep coming back to: it’s rich, no-bake, and reliably creamy without dairy or refined carbs. It freezes beautifully, slices cleanly if you chill it long enough, and hits that peanut-butter-and-chocolate comfort zone while staying keto-friendly.
There are a few straightforward steps: soak, blend, press, freeze, and top. Timing is mostly hands-off — soak the cashews, freeze the crust, then blitz the filling and chill. The ingredient list is short and specific; follow the order and measurements and you’ll get steady results.
Below I walk you through everything: exactly what to gather, step-by-step assembly, swaps if you need them, and storage tips so the pie is ready when guests arrive. No fluff. Just useful, real-world advice from my kitchen to yours.
What You’ll Gather
- 2 cups raw almonds — the base for a sturdy, nut-forward crust; pulse until finely ground.
- 6 Tbsp coconut oil + more if needed — binds the crust and adds richness; keep it soft but not melted hot.
- 5 Tbsp sugar-free confectioners sugar — sweetens the crust without carbs from sugar.
- 3 Tbsp raw cacao powder* — deep chocolate flavor for the crust; sift if lumpy.
- 1 1/2 cups raw cashews soaked — soaked to make the silky, dairy-free filling; soak fully for best texture.
- 1 ½ cups unsweetened creamy peanut butter — the star flavor; use a smooth, unsweetened variety.
- 1 ⅓ cups full fat canned coconut milk plus more if needed — adds creaminess and helps the filling blend smooth.
- 1 cup sugar-free confectioners sugar or more to taste — sweetens the filling; adjust to your preference.
- 1/2 tsp sea salt to taste — balances the sweetness and enhances the peanut butter.
- 1 tsp pure vanilla extract — lifts the flavors and rounds the filling.
- ½ cup full-fat canned coconut milk** — used for the ganache; warm but not boiling when combined with chocolate.
- 1 cup sugar-free chocolate chips — creates the chocolate topping; melt gently for shine.
- 1 Tbsp coconut oil*** — smooths and glosses the ganache.
- Pinch sea salt — for finishing; optional but makes the chocolate sing.
Dairy-Free Low-Carb Peanut Butter Pie in Steps
- Place 1 1/2 cups raw cashews in a large bowl and pour boiling water over them until completely covered. Soak at least 2 hours or up to overnight.
- While the cashews soak, make the crust: add 2 cups raw almonds, 6 Tbsp coconut oil (plus more if needed), 5 Tbsp sugar-free confectioners’ sugar, and 3 Tbsp raw cacao powder to a food processor. Process until the mixture comes together into a thick dough (the consistency of very thick nut butter or cookie dough). If it seems too dry, add a little more coconut oil, 1 teaspoon at a time.
- Line an 8-inch springform pan with parchment paper. Transfer the crust mixture into the pan and press it into an even layer across the bottom (and slightly up the sides if you prefer). Place the pan in the freezer while you finish the filling.
- Drain the soaked cashews in a colander and discard the soaking water.
- Make the filling: in a high-powered blender, combine 1 1/3 cups full-fat canned coconut milk and 1 1/2 cups unsweetened creamy peanut butter. Blend until completely smooth.
- Add the drained 1 1/2 cups soaked cashews, 1 cup sugar-free confectioners’ sugar (or more to taste), 1 tsp pure vanilla extract, and 1/2 tsp sea salt to the blender. Blend until the filling is completely smooth and creamy, scraping down the sides as needed. If the mixture is too thick to blend smoothly, add additional full-fat canned coconut milk a tablespoon at a time (as needed) until it reaches a spreadable, smooth consistency.
- Pour or spread the filling evenly over the frozen crust. Smooth the top with a spatula, then return the pan to the freezer and freeze for 1 hour.
- Make the chocolate ganache: in a microwave-safe bowl combine 1 cup sugar-free chocolate chips, 1/2 cup full-fat canned coconut milk, and 1 Tbsp coconut oil. Microwave in 20-second intervals, stirring thoroughly between intervals, until the chocolate is melted and the mixture is smooth (about 60 seconds total). Let the ganache cool briefly until pourable but not hot.
- Pour the ganache over the chilled filling and spread into an even layer. Sprinkle a pinch of sea salt over the top if desired.
- Freeze the pie for at least another hour (longer if you prefer firmer, cleaner slices). When ready to serve, run a sharp knife around the edge, slice, and enjoy.
What Makes This Recipe Special
This pie is built around texture and contrast. The crust is dense and nutty, thanks to whole almonds and just enough coconut oil to bind. The filling is velvety because soaked cashews and coconut milk create an emulsion that mimics cream cheese or heavy cream without any dairy.
Low-carb and sugar-free elements are intentional: sugar-free confectioners’ sugar and sugar-free chocolate chips keep the net carbs down while preserving the dessert profile. The peanut butter gives deep, familiar flavor and the ganache adds a clean chocolate finish. It’s a dessert that feels indulgent but works for dairy-free and lower-carb diets.
What to Use Instead
If you need swaps, these are practical options I’ve used or tested:
- Almonds (crust) — swap for blanched almond flour in a pinch, but the texture will be slightly different.
- Coconut oil — neutral oils won’t set the crust as cleanly; if necessary, use melted coconut butter but expect a softer crust.
- Sugar-free confectioners’ sugar — erythritol-based powdered sweeteners are the closest match; adjust sweetness to taste.
- Raw cashews — use roasted unsalted cashews only if you can’t soak raw ones; soak them to soften before blending.
- Unsweetened creamy peanut butter — almond butter works for a different nut profile; expect milder peanut flavor.
Cook’s Kit
Simple kit, nothing fancy. Here’s what I use every time:
- Food processor — for the crust, a strong pulse is key.
- High-powered blender — the filling needs a smooth, lump-free texture.
- 8-inch springform pan — makes unmolding easy and gives neat slices.
- Spatula and offset spatula — for smoothing filling and ganache.
- Measuring cups and spoons — precise amounts matter for texture and freezing behavior.
Slip-Ups to Skip
These are the mistakes I’ve learned from so you don’t repeat them.
- Under-soaking cashews — they must be soft enough to blend totally smooth. If not, the filling will be grainy.
- Blending the filling cold — cold fillings thicken and can gum up the blender. Use room-temperature coconut milk and warm blender runs, adding extra tablespoonfuls of coconut milk only as needed.
- Rushing the freeze time — slicing too soon leads to messy pieces. Let the pie freeze at least the recommended hour after the ganache, longer if you want clean slices.
- Overheating ganache — microwave in short bursts and stir. Too-hot chocolate can seize or become grainy.
Seasonal Ingredient Swaps
Small seasonal tweaks keep this pie fresh.
- Fall: stir a pinch of cinnamon or nutmeg into the filling for warmth.
- Winter: top with toasted coconut flakes for texture and a festive look.
- Spring/Summer: serve thin slices with a handful of fresh berries on the plate to cut the richness.
Notes on Ingredients
A quick explanation of why each ingredient matters and how to choose them.
- Raw almonds — provide structure and a blank canvas for cacao.
- Coconut oil — solid at cooler temps; it helps the crust set and the ganache gloss.
- Sugar-free confectioners’ sugar — powdered sweetener dissolves better than granulated for smooth textures.
- Raw cacao powder — darker, less sweet than standard cocoa; it adds depth without sugar.
- Raw cashews — when soaked, they blend into a creamy, neutral-flavored base that replaces dairy.
- Unsweetened creamy peanut butter — choose one with no salt or oil separation for predictable consistency.
- Full-fat canned coconut milk — fat content is important for creaminess; light versions won’t produce the same texture.
- Sugar-free chocolate chips — use ones formulated to melt smoothly (many erythritol or stevia-based chips do fine).
- Sea salt — a pinch brightens flavors; it’s part of balancing sweet and savory.
Shelf Life & Storage
This pie is best stored frozen. Keep it wrapped or in an airtight container.
- Refrigerator (after thawing): keep slices covered for up to 5 days. They soften in the fridge; store on a plate lined with parchment to catch any oil separation.
- Freezer: wrapped tightly in plastic and stored in an airtight container, the pie keeps well for up to 3 months. Thaw in the fridge for a few hours before serving for best texture.
- To serve: allow slices to sit at room temperature for 5–10 minutes to make them easier to cut and more pleasant to eat.
Dairy-Free Low-Carb Peanut Butter Pie FAQs
Quick answers to common questions I get from readers.
- Can I make this nut-free? Swapping nuts changes the structure significantly. If you need nut-free, substitute the crust with a seed-based crust (sunflower or pumpkin seeds) and expect different texture and flavor.
- Why soak the cashews? Soaking softens them so they blend into a silky, dairy-like cream. Shorter soaks yield a grainier filling.
- How do I get clean slices? Freeze the pie solid and use a hot, sharp knife wiped between cuts. Thicker, chilled slices hold shape better.
- Can I make it ahead? Yes. It keeps frozen for months and is perfect to have on hand for guests.
- Is this truly low-carb? With sugar-free sweeteners and nut-based crust, it’s low-carb relative to traditional pies; check your specific brands for exact macros.
Bring It to the Table
Presentation is simple: slice with a sharp knife, transfer slices with a palate knife onto chilled plates, and add a tiny sprinkle of flaky salt on top of each slice. Fresh raspberries or a few toasted peanut halves make an attractive contrast and add a pop of texture.
Serve this pie slightly chilled. It’s rich, so smaller slices work well, especially after a big meal. If you want to make it a celebration dessert, pair with unsweetened whipped coconut cream or a drizzle of warmed, sugar-free caramel for a dramatic finish.
Make the crust and filling the day before, finish with ganache the morning of. That staging saves time and keeps the pie looking polished when guests arrive. Enjoy — and take a moment to appreciate how a few simple, dairy-free swaps can still deliver a classic flavor combo.

Notes
*unsweetened cocoa powder
**In total, you will need 1 (15-oz) can of full-fat coconut milk – part of which will be used for the peanut butter cheesecake filling, and the remainder of which will be used for the chocolate ganache.
***You can replace the coconut oil with butter if you do dairy.
