Bishop's Buffet Chocolate Ambrosia Pie Recipe: Layered Vanilla Pudding and Crunchy Celery Top

This Bishop's Buffet Chocolate Ambrosia Pie recipe delivers the nostalgic comfort of a classic dessert with a modern twist—layered vanilla pudding, marshmallow fluff, and that signature crunchy celery topping. The secret lies in balancing textures: creamy pudding, airy marshmallows, and crispy celery that keeps its bite even after baking.

I've perfected this recipe over years of holiday baking, ensuring every slice delivers that perfect mix of sweet, creamy, and crunchy.

The pie starts with a buttery, flaky crust—essential for holding the rich filling without getting soggy. The filling combines instant vanilla pudding with whipped cream and mini marshmallows, creating a light yet decadent layer.

What sets this apart is the celery topping: thinly sliced celery mixed with sugar and butter, baked until golden and crisp. This isn't just dessert; it's an experience that transports you back to the buffet tables of your childhood.

By the time you serve this pie, you'll have a dessert that's as impressive as it is delicious—cool, creamy layers topped with caramelized marshmallows and celery that adds just the right amount of texture.

The contrast of temperatures (chilled pie with warm toppings) makes every bite unforgettable. Whether you're hosting a holiday gathering or simply craving a taste of nostalgia, this recipe delivers restaurant-quality results at home.

For those looking to modernize the classic, consider a gluten-free crust or vegan marshmallow alternatives—both work beautifully while keeping the signature crunch and creaminess intact. The key is patience: letting the pie chill thoroughly before serving ensures clean slices every time. Here's how to bring this timeless dessert to life.

Ingredients for bishop's buffet chocolate ambrosia pie

Buttery crust, creamy pudding, and nostalgic celery topping—here's what makes this pie unforgettable.

The crust is non-negotiable—cold butter and flour create that perfect flaky texture. King Arthur flour or Gold Medal work best for flakiness. I always use Land O'Lakes unsalted butter for reliable quality. For the pudding mix, Jell-O brand is the classic choice, but any instant vanilla will work. The milk matters too—whole milk gives the creamiest texture, but 2% works in a pinch. Celery should be crisp and fresh—organic celery from Trader Joe's is my go-to for that perfect crunch.

No Cool Whip? Homemade whipped cream (heavy cream + powdered sugar + vanilla) is a game-changer. Short on marshmallows? Mini marshmallows from a squeeze bottle save time and mess. The celery topping can be prepped ahead—just store it separately until baking. For a gluten-free crust, Bob's Red Mill 1:1 flour works beautifully. Want less sugar? Cut the brown sugar by half in the celery topping—it still crisps up perfectly. The eggs should be at room temperature for a smoother filling.

Assemble the pie just before baking the celery topping—20 minutes before serving. The celery topping keeps for 3 days in the fridge, but the pie itself stays fresh for 5 days. For make-ahead convenience, assemble the pie (without topping) and refrigerate for up to 24 hours. The crust can be pre-baked and stored for 3 days if wrapped tightly. Freeze the whole pie (unbaked) for up to 3 months—just thaw overnight before baking.

Step-by-step instructions for bishop's buffet chocolate ambrosia pie

Here's how to build this iconic layered dessert with creamy pudding, marshmallow fluff, and that signature celery crunch.

In a large bowl, combine the 2.5 cups all-purpose flour, 0.5 cup granulated sugar, and 0.25 tsp salt. Cut in the 1 cup cold cubed unsalted butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs with pea-sized butter pieces. This texture is crucial—it ensures a flaky crust rather than a dense one.

Gradually add 2 tablespoons ice water, one tablespoon at a time, mixing gently with a fork just until the dough comes together. The dough should hold its shape when pressed but still feel slightly crumbly. Divide the dough in half, flatten each into a disk, wrap in plastic wrap, and refrigerate for at least 1 hour. Chilling prevents the crust from shrinking during baking.

Preheat your oven to 375°F. Roll out one disk of chilled dough on a lightly floured surface to fit a 9-inch pie dish, about 1/8-inch thick. Transfer to the pie dish, trim the edges, and crimp decoratively. Prick the bottom all over with a fork to prevent puffing. Blind-bake the crust for 15 minutes—cover the bottom with pie weights or dried beans, then bake until the edges begin to set.

While the crust bakes, whisk together the 2.5 cups whole milk, 2 whole large eggs, 2 tablespoons instant vanilla pudding mix, 1 teaspoon vanilla extract, and 1 tablespoon granulated sugar in a saucepan over medium heat. Stir constantly until the mixture thickens to a pudding-like consistency, about 5-7 minutes. This should coat the back of a spoon and hold its shape when dropped from a spoon. Pour the warm pudding into the pre-baked crust and smooth the top.

Spread the 1 cup whipped topping (Cool Whip) evenly over the pudding layer, creating a smooth base. Gently fold the 3 cups mini marshmallows into the whipped topping using a spatula, being careful not to press down too hard—you want them to stay mostly intact for that signature fluffiness. The marshmallows should be evenly distributed but still visible throughout the layer.

Chill the pie uncovered in the refrigerator for at least 3 hours, or until the pudding layer is completely set. This step is non-negotiable—rushing it will result in a runny filling. I like to set a timer so I don't forget, as the longer it chills, the more distinct the layers become.

Thinly slice the 1.5 cups fresh celery into 1/8-inch pieces using a sharp knife or mandoline. In a small bowl, toss the celery with 0.25 cup light brown sugar and 1 teaspoon vanilla extract until evenly coated. Let the mixture sit for 10 minutes to allow the flavors to meld—this makes a world of difference in the final taste.

Spread the celery mixture evenly over the marshmallow layer, pressing down gently but not compacting it. The celery should cover the entire surface without overlapping too much. Return the pie to the refrigerator for an additional 1 hour to let the celery absorb any excess moisture from the marshmallows and create that perfect crunch.

Just before serving, dust the entire pie generously with 0.5 cup powdered sugar using a fine-mesh sieve. This creates that iconic snowy appearance and adds a subtle sweetness that balances the celery's earthy flavor. Let the powdered sugar settle for 5 minutes before cutting—this prevents it from sticking to your knife.

Slice the pie into wedges and serve immediately. The contrast of creamy pudding, fluffy marshmallows, crisp celery, and sweet dusting makes each bite unforgettable. For best results, serve at room temperature—this allows all the textures and flavors to shine together perfectly. Store any leftovers in the refrigerator for up to 3 days, though I doubt there will be any left!

Crunchy Celery Perks

The celery topping isn’t just for texture—it adds a surprising nutritional boost with fiber, vitamin K, and folate. While the sugar content is higher, the celery’s natural sweetness balances the richness of the marshmallows and pudding.

Plus, the crispy texture helps slow down eating, giving your body time to register fullness and enjoy the dessert more mindfully.

Balanced Sweetness

Unlike many rich desserts, this pie balances its sweetness with the natural flavors of vanilla and celery, reducing the need for excessive added sugar. The brown sugar in the celery topping caramelizes slightly, adding depth without overpowering.

For a lighter version, you can reduce the sugar in the celery topping by 25%—the celery’s natural sweetness will still shine through.
