Almond Milk Custard Pie Recipe: Silky Plant-Based Creaminess in Crustless Bliss

This almond milk custard pie recipe delivers velvety plant-based richness without a single drop of dairy. The secret lies in a nutty almond flour crust that stays crisp while cradling a silky custard filling made with almond milk, vanilla, and just enough sweetness to satisfy.

What makes this version special is how it achieves that signature custard texture—creamy yet firm—using simple pantry staples and a foolproof technique that eliminates the guesswork of traditional custard recipes.

The crust gets its structure from almond flour and a touch of coconut oil, creating a delicate yet sturdy base that holds up beautifully.

For the filling, we use almond milk as the liquid base, thickened with cornstarch for that signature smoothness, while vanilla and a pinch of salt enhance the natural nutty flavor profile.

The result is a pie that's naturally vegetarian and can easily be adapted to vegan with simple substitutions—no one will miss the dairy.

What you'll end up with is a pie that's silky smooth on the inside and perfectly set, with a golden crust that adds just enough texture to contrast the creamy filling. The aroma alone as it bakes will transform your kitchen into a cozy dessert haven.

This recipe is perfect for special occasions or when you want to impress guests with a dessert that's both elegant and approachable.

Serve it warm with a drizzle of caramel or fresh berries for added brightness, or enjoy it chilled for a refreshing treat. The beauty of this recipe is its versatility—it works equally well as a showstopping centerpiece or a comforting weeknight dessert. Let's get started on creating this plant-based masterpiece!

Ingredients for almond milk custard pie

Almond flour, coconut oil, and almond milk—just the basics for this dreamy plant-based pie.

Almond flour is the star here. Bob's Red Mill or Anthony's Goods are my go-tos—they're finely ground and consistent. The unsweetened almond milk matters too; Silk or Blue Diamond are reliable brands that won't add weird aftertastes. For the coconut oil, grab the unrefined version if you can—it's got a nicer flavor, though refined works fine. The sugar? Domino or Sugar in the Raw both work perfectly. If you're feeling fancy, swap the granulated sugar for coconut sugar—it adds subtle caramel notes.

No almond flour? Oat flour or almond meal can work in a pinch, but texture might differ slightly. Short on almond milk? Cashew milk or oat milk are great swaps—just use the same amount. The cornstarch is non-negotiable for that perfect custard texture, but if you're gluten-free, make sure it's certified. Fresh vanilla extract is ideal, but imitation vanilla works if that's all you've got. For the lemon juice, bottled is fine—just make sure it's 100% lemon juice, no added water. The blueberries? Frozen are great if you're in a hurry—just thaw and drain them first.

This pie keeps beautifully in the fridge for 4-5 days, though it's best enjoyed fresh. For make-ahead prep, assemble it the night before and bake in the morning—it reheats wonderfully. If you're freezing it, wait until it's completely cooled, then wrap tightly in plastic wrap and foil. It'll last for up to 3 months. The crust stays crisp for about 2 days, so if you're making this ahead, consider baking it fresh. And trust me, the smell as it bakes? Worth every minute of wait time.

Step-by-step instructions for almond milk custard pie

Here's how to create a velvety plant-based custard that's rich, creamy, and perfect every time.

In a medium saucepan, gently melt the 0.5 cup unsalted coconut oil over low heat until completely liquid but not hot to the touch. Remove from heat and let it cool slightly for 2 minutes. Meanwhile, in a large mixing bowl, whisk together the 1.5 cups almond flour, 0.5 cup cornstarch, 1.25 cups granulated sugar, 0.25 tsp salt, and 0.5 tsp ground cinnamon until fully combined. This dry blend forms the custard's thickener and flavor base.

I like to use a whisk for this step to avoid developing gluten in the almond flour. The cinnamon is optional but adds warmth that pairs beautifully with the almond flavor. If using brown sugar, you'll get a slightly deeper caramel note in the finished pie.

Return the melted coconut oil to low heat and gradually whisk in 2 cups unsweetened almond milk until smooth. Add the dry ingredient mixture all at once and whisk vigorously for 2-3 minutes until the mixture thickens noticeably. You're looking for a consistency similar to thick pudding—it should coat the back of a spoon but still be pourable.

This is where the magic happens. The cornstarch transforms the almond milk into a silky custard. If you see any lumps, strain the mixture through a fine-mesh sieve for a perfectly smooth texture. The custard should be thick enough to hold its shape when spooned but still flow gently.

Remove the saucepan from heat and stir in the 1 tbsp pure vanilla extract and 1 tbsp lemon juice. The lemon juice brightens the almond flavor while preventing the custard from becoming too sweet. Return the mixture to medium-low heat and cook for 5-7 minutes, stirring constantly, until it reaches 180°F on an instant-read thermometer. This temperature ensures the custard is fully set without curdling.

Here's the thing—don't walk away during this step. The custard can go from perfect to lumpy in seconds if you're not paying attention. You'll know it's ready when it's thick enough to coat the back of a spoon and leaves a clean trail when you run your finger through it.

Pour the hot custard into a 9-inch pie dish or individual ramekins. If using, arrange the 1.5 cups fresh blueberries on top in a decorative pattern. Let the custard cool to room temperature for 30 minutes, then refrigerate for at least 4 hours (overnight is best). This chilling time is crucial—it allows the custard to fully set and develop its signature silky texture.

For the best results, I recommend chilling overnight. The longer it sets, the creamier it becomes. If you're in a hurry, you can speed up the process by placing the pie dish in an ice bath for 30 minutes before transferring to the fridge. Just be sure it's fully set before serving.

Once fully chilled, run a knife around the edges of the pie to loosen it from the dish. Serve as-is or dust the top with 0.25 cup powdered sugar for a sweet finish. The custard should be firm enough to slice cleanly but still have that luxurious, creamy mouthfeel. If you're serving it warm, let it sit at room temperature for 10 minutes first to soften slightly.

This pie tastes even better the next day as the flavors meld together. Store any leftovers in the fridge for up to 3 days or freeze for 2 months. The plant-based ingredients actually improve with time, making this custard pie a great make-ahead dessert for gatherings or special occasions.

Perfect pairings for this dish

Fruity Toppings

Fresh berries like blueberries or raspberries add vibrant color and a juicy contrast to the creamy custard. I recommend using 1.5 cups fresh blueberries arranged in a decorative pattern on top before baking.

For a tropical twist, try mango slices or passion fruit pulp—their natural sweetness complements the almond flavor beautifully. 🍓

Caramel Drizzle

A rich salted caramel drizzle takes this pie to the next level. I love using homemade caramel sauce (simmer 1 cup sugar until amber, then whisk in ½ cup heavy cream and 1 tsp sea salt).

Drizzle over the chilled pie just before serving for a luxurious finish. For a plant-based option, use coconut cream instead of heavy cream.
