Save A nostalgic, creamy pie inspired by the classic soda fountain Coke float, featuring a fizzy cola-infused filling and a fluffy whipped topping.
I’ve been getting a lot of questions about the pot I use for cozy one-pot meals and small-batch recipes, so I wanted to quickly share it here.
This is the Martha Stewart heart-shaped enameled cast iron Dutch oven (2-quart). It’s one of those pieces I reach for constantly when testing soups, stews, baked casseroles, and smaller comfort-food recipes.
- Heats evenly with no hot spots (huge for slow cooking)
- Non-reactive enamel interior — no seasoning required
- Perfect size for small households or side dishes
- Sturdy handles, easy to move from oven to table
It’s also a favorite with home cooks — 4.6 out of 5 stars from over 1,900 reviews — and Amazon often has a coupon available, depending on color and size.

Instructions
- Make the Crust:
- Preheat oven to 350°F (175°C). Combine graham cracker crumbs, sugar, and melted butter in a bowl. Press into a 9-inch pie plate. Bake 8–10 minutes until lightly golden. Cool completely.
- Prepare Coke Float Filling:
- In a medium saucepan, whisk together Coca-Cola, sugar, cornstarch, and salt until smooth. In a separate bowl, whisk milk and egg yolks. Heat cola mixture over medium, stirring often, until simmering. Slowly whisk some hot cola into milk and egg yolks to temper, then pour back into the saucepan. Cook, stirring, until thickened (3–4 minutes). Remove from heat. Stir in butter and vanilla until smooth. Whip 1/2 cup heavy cream to soft peaks and fold into cooled cola custard. Pour into cooled crust and chill for at least 4 hours until set.
- Add Whipped Topping & Serve:
- Whip remaining 1 cup heavy cream with powdered sugar to stiff peaks. Spread over pie and garnish with maraschino cherries. Slice and serve chilled.

Recipe FAQ
- → Can I use diet soda for the filling?
Regular Coca-Cola is recommended for best flavor and texture. Diet sodas may affect the taste and setting.
- → Is a store-bought crust suitable?
Yes, a premade graham cracker or chocolate crust can be used for convenience.
- → How long does the pie need to chill?
Chill for at least 4 hours until the filling is fully set and firm.
- → Can I make this dairy-free?
Try substituting plant-based milk and cream alternatives, but note the texture may change.
- → What makes the filling fizzy?
Coca-Cola provides a subtle fizzy flavor and lightness to the custard once cooked and mixed with cream.
- → Is it possible to freeze leftovers?
Freezing may alter the texture of the whipped topping and filling, so refrigeration is preferred.
