How to Make Black Bottom Pie Recipe
Step 1: Create the Chocolate Base
Begin by melting the chocolate chips in a heat-safe bowl together with one cup of the hot scalded milk custard. This ensures a glossy, smooth chocolate that will form the rich bottom layer. Stir in the vanilla extract to infuse sweetness and complexity. Pour this mixture carefully into your pre-baked pie shell, then chill it until firm. This step sets the stage for the luscious contrasts to come.
Step 2: Prepare the Rum Custard
Soften the unflavored gelatin by sprinkling it over cold water and letting it sit. While it blooms, whisk together the egg yolks, remaining milk, sugar, and cornstarch in a saucepan until smooth. Heat this mixture gently, stirring constantly, until it thickens into a creamy custard. Remove from heat and stir in the softened gelatin until fully dissolved. Finally, blend in the rum for that warm, inviting edge. Allow this custard to cool until just starting to thicken.
Step 3: Whip the Egg Whites
In a clean, dry bowl, beat the egg whites along with the remaining sugar until stiff peaks form. This step brings incredible lightness and volume to the pie’s filling. Carefully fold the whipped egg whites into the slightly thickened rum custard, preserving as much air as possible for that perfect airy texture in the final pie.
Step 4: Assemble the Pie Layers
Gently pour the rum custard mixture over the chilled chocolate base in the pie shell. Be careful not to disturb the firm bottom layer. Once filled, refrigerate the pie for at least an hour or place it in the freezer for 30 minutes to speed up the setting process. This allows the flavors to meld and the filling to firm up beautifully.
Step 5: Finish with a Fluffy Topping
Just before serving, spread the whipped dessert topping evenly over the pie. For an optional touch of elegance and extra chocolate flavor, sprinkle shaved unsweetened chocolate on top. This final flourish elevates the texture and adds a rich, bittersweet contrast to the creamy sweetness beneath.
How to Serve Black Bottom Pie Recipe

Garnishes
Think beyond just whipped topping—adding chocolate shavings, a dusting of cocoa powder, or a few fresh raspberries can brighten the pie visually and palate-wise. A sprig of mint gives a pop of color and a refreshing aroma that complements the chocolate and rum beautifully.
Side Dishes
A slice of this Black Bottom Pie Recipe pairs wonderfully with a simple cup of strong coffee or a glass of sweet dessert wine. Lightly toasted nuts or a small bowl of fresh berries on the side add texture and balance to the indulgence.
Creative Ways to Present
For parties, consider serving the pie in individual clear dessert glasses layered with crushed cookies and custard for a deconstructed spin. Or place slices on a dessert platter with assorted toppings nearby so guests can customize each bite—pure fun and delicious!
Make Ahead and Storage
Storing Leftovers
This pie keeps beautifully in the refrigerator for up to three days. Cover it tightly with plastic wrap or place it in an airtight container to maintain freshness and prevent it from absorbing other fridge odors.
Freezing
You can freeze the pie if you want to prepare it ahead of time. Wrap it well in multiple layers of plastic wrap and foil to protect against freezer burn. When ready to serve, thaw it in the refrigerator overnight to preserve the delicate custard texture.
Reheating
This pie is best enjoyed chilled, so it does not require reheating. If you like, you can let it sit at room temperature for 15 minutes before serving to intensify flavors without losing that cool, creamy experience.
FAQs
Can I use a store-bought pie crust for this recipe?
Absolutely! A store-bought baked pie shell works perfectly for this Black Bottom Pie Recipe and saves you time without compromising flavor or texture.
Is the rum essential in the custard?
The rum adds warmth and complexity, but you can omit or substitute it with vanilla extract or a non-alcoholic rum flavoring if preferred.
Can I make this pie dairy-free?
Yes, by substituting the milk with almond, coconut, or oat milk, and using dairy-free chocolate chips and whipped topping, you can adapt the recipe to be dairy-free while still keeping that creamy texture.
How can I tell when the custard is thick enough?
The custard will coat the back of a spoon and hold a line you draw with your finger without it running. It should look smooth and slightly thickened before incorporating the gelatin and rum.
Is it safe to eat the custard since it contains eggs?
Since the recipe uses cooked custard and whipped egg whites that are not cooked, make sure to use very fresh eggs or pasteurized egg whites to minimize any risk, especially if serving to children or pregnant individuals.

- 1 cup Sugar, divided
- 1 Envelope Unflavored Gelatin
- ¼ cup Cold Water
- 1 tbsp Rum
Topping

Instructions
- Prepare the Chocolate Layer: Melt the chocolate chips in a heat-resistant bowl by combining them with 1 cup of hot custard mixture (milk, eggs, cornstarch, and part of the sugar scalded together). Stir in vanilla extract until smooth. Pour this chocolate mixture into the baked pie shell. Chill in the refrigerator to set.

- Add the Final Touch: Frost the top of the pie with whipped dessert topping. Optionally, garnish with shaved unsweetened chocolate for an elegant finish.
Notes
- Ensure the pie shell is completely cooled before adding the chocolate layer to prevent melting.
- If you prefer non-alcoholic versions, omit the rum or substitute with rum flavoring.
- Use fresh eggs and handle egg whites carefully to achieve the best volume when whipping.
- Chilling the pie adequately is essential for clean slices and proper setting.
- The optional shaved unsweetened chocolate adds a nice contrast and texture but can be omitted if desired.
