Ingredients for 3 ingredient peanut butter pie recipe easy

Three ingredients, zero fuss, and a pie that tastes like pure indulgence—no baking required.

The graham cracker crust is your foundation—Honey Maid vegan graham crackers from the baking aisle are a game-changer, but any sturdy vegan graham cracker will work. Look for packages labeled ‘vegan’ to avoid hidden dairy. The peanut butter? Natural, unsweetened is ideal (like Smucker’s or Crazy Richard’s), but creamy store brands work too. Skip the crunchy—we want that silky texture. For the coconut milk, Goya or Thai Kitchen brands are my go-tos—they’re thick, sweetened, and perfect for this recipe. No need to hunt for specialty items here; these are all pantry staples with a little label-reading.

No peanut butter? Sunflower seed butter is a great nut-free swap, though the flavor will differ slightly. Short on coconut milk? Substitute sweetened condensed coconut cream or even a mix of coconut milk and sugar (1 cup coconut milk + 1/2 cup sugar, simmered to thicken). The crust can be made ahead and stored in the fridge for 3 days or frozen for 1 month. Just let it soften at room temp before assembling. For extra richness, add a pinch of vanilla extract or cinnamon to the filling—trust me, it elevates everything.

This pie is all about patience—chill the filling for at least 4 hours (overnight is best) for that perfect texture. Store leftovers in the fridge for 5 days, though I’ve never had any last that long. The crust stays crispy when kept in an airtight container, and the filling holds its shape beautifully. For serving, a quick dusting of powdered sugar or crushed peanuts adds a pro touch. Freezes like a dream too—just thaw in the fridge before slicing. No stress, no mess, just pure peanut butter bliss.

Step-by-step instructions for no-bake peanut butter pie

This three-ingredient wonder comes together faster than you can say “dessert” – let’s make it.

Remove the 1 package Graham Cracker Crust (15 oz package) from its box and place it on a flat surface. Press down firmly and evenly with your hands or a rolling pin to create a solid, level base for your pie. You want the crust to be about ¼-inch thick throughout – this ensures even support for your filling and prevents cracking.

Here’s the thing – don’t worry if it’s not perfect. Graham cracker crusts are forgiving. Just make sure the edges are sealed tightly to the bottom of your pie dish. If you’re using vegan graham crackers, this step is even easier as they tend to hold their shape better. Place the prepared crust in your pie dish and set it aside while you prepare the filling.

In a medium mixing bowl, scoop out the 2 cups Creamy Peanut Butter. I like to use natural, unsweetened peanut butter for a more authentic flavor, but any creamy peanut butter will work. Add the 13.5 oz Sweetened Condensed Coconut Milk to the peanut butter and stir vigorously with a sturdy spoon or spatula.

You’ll notice the mixture will be quite thick initially. Keep stirring until it becomes smooth and creamy – about 2-3 minutes of continuous mixing. The condensed coconut milk will begin to incorporate fully, creating a thick, spreadable filling. This is where the magic happens – the coconut milk’s sweetness and creaminess perfectly complement the peanut butter’s richness.

Carefully pour the peanut butter mixture over the prepared graham cracker crust in your pie dish. Use a spatula to spread it out evenly, making sure it reaches all the edges. You want a smooth, level surface – about ½-inch thick throughout. This ensures even cooling and a consistent texture in every bite.

Don’t worry if it looks a bit messy at first. The filling will settle as it cools. For a perfect finish, I like to run the spatula around the edges to create a clean border. This step is crucial for that restaurant-quality look that makes your pie look as good as it tastes.

Cover your pie tightly with plastic wrap and refrigerate for at least 4 hours, or until completely firm. This is where patience pays off – the longer it chills, the thicker and more stable the filling becomes. I know it’s tempting to cut into it sooner, but trust me, waiting ensures that perfect slice every time.

Here’s a pro tip: If you’re really impatient, you can pop your pie in the freezer for 2 hours to speed up the process. Just make sure it’s fully set before serving. When it’s ready, you’ll see a clean break when you lift the pie from the dish – that’s your signal it’s perfect.

Storing and reheating your leftovers

Fridge Storage

Once your pie is fully set, store it in an airtight container in the refrigerator for up to 5 days. The graham cracker crust stays crispy while the peanut butter filling maintains its creamy texture beautifully.

I like to wrap the pie dish itself in plastic wrap before placing it in the container—this prevents any potential condensation from making the crust soggy. 🥧

If you’re storing leftovers, slice the pie first and keep each piece individually wrapped. This makes it easy to grab just one slice when you’re craving that peanut butter goodness.

The filling will firm up again once chilled, so no worries about messy textures. Trust me, it’s perfect for quick dessert cravings.

Freezer Prep

This pie freezes exceptionally well for up to 3 months, making it perfect for meal prep or holiday gatherings. Wrap the entire pie dish tightly in plastic wrap followed by aluminum foil to prevent freezer burn.

Label it with the date so you can keep track of how long it’s been stored. 🧊

When you’re ready to serve, thaw the pie in the refrigerator overnight. This slow thawing process ensures the filling comes back together smoothly without any separation.

If you’re in a hurry, you can leave it at room temperature for about 2 hours, but I recommend the overnight method for best results.

Reheating Slices

For individual slices, there’s no need to reheat—just serve them straight from the fridge. The cold temperature actually enhances the creamy texture and makes each bite even more satisfying.

If you prefer your pie slightly warmed, you can microwave a single slice for 10-15 seconds on 50% power to soften the crust slightly without melting the filling. 🔥

For the whole pie, if you’ve stored it in the freezer, you’ll need to thaw it completely before slicing. Once thawed, serve it straight from the fridge.

The texture will be perfect—no need for any additional reheating. This pie is designed to be enjoyed cold, so embrace that creamy, cool goodness.

Crust Refresh

If you notice the crust losing its crispness after storage, pop the pie in the oven for 5-7 minutes at 350°F to refresh it. This works wonders for reviving that perfect texture without affecting the filling. Just keep an eye on it so it doesn’t over-bake. ✨

For extra crunch, you can also sprinkle a layer of crushed graham crackers on top of the filling before it sets in the fridge. This creates a delicious textural contrast that adds another dimension to your pie. It’s a simple trick that makes all the difference.
