This Keto Pumpkin Custard is what I make when I want the flavor of pumpkin pie without rolling out a crust or committing to a full dessert. Everything whisks together in one bowl, bakes gently in a water bath, and sets into something silky and rich.

I like this one for how little it asks of you. A handful of ingredients, minimal prep, and the water bath does the real work of keeping the texture smooth instead of curdled or rubbery.
Don’t skip the water bath. It’s the difference between a silky custard and one with an uneven, slightly grainy texture.
Chef Jenn’s Take on Keto Pumpkin Custard
A lot of baked custards turn out grainy or slightly curdled, usually because they went into a dry oven with direct heat instead of a water bath. Custard is delicate, and direct heat cooks the edges too fast while the center lags behind.
The water bath is what keeps this custard smooth from edge to center. It surrounds the ramekins with gentle, even heat instead of the direct blast of a dry oven, which is exactly what keeps eggs from curdling as they set. Pull the custards while the center still has a slight jiggle, since they’ll continue to set a bit as they cool. For more low-carb fall desserts like this one, check out my Desserts collection.
What You’ll Love About Keto Pumpkin Custard
- It tastes like the best part of pumpkin pie, the smooth, spiced filling, without any of the work that goes into a crust.
- It bakes in individual ramekins, so portions are already built in and it looks more elegant than the effort it actually takes.
- It works warm or chilled, so it adapts to whatever mood you’re in when dessert time rolls around.
Ingredients
- Pumpkin puree – Make sure it’s pure pumpkin, not pumpkin pie filling, which already has added sugar and spices mixed in.
- Eggs – Large or extra-large both work fine.
- Heavy whipping cream
- Erythritol powder – Or your favorite keto sweetener, adjusting to taste.
- Vanilla extract – Artificial extract works fine here if that’s what you have.
- Stevia powder
- Pumpkin spice – Fresh spice blend gives noticeably more flavor than one that’s been sitting a while.
How to Make Pumpkin Custard

Preheat your oven to 350°F (180°C) so it’s ready when the custard goes in.
In a mixing bowl, whisk together the pumpkin puree, eggs, heavy cream, erythritol, vanilla, stevia, and pumpkin spice. Whisk until the mixture is completely smooth and well combined. Pour the custard evenly into four oven-safe ramekins.
Place the filled ramekins inside a larger baking dish or cake pan. Pour about 2 inches (3 cm) of hot water into the pan so the ramekins sit in a shallow bath. This gentle steaming helps the custard cook evenly without curdling.
Transfer the entire dish to the oven and bake for 50 minutes, or until the custard is set but still slightly jiggly in the center.
Carefully remove the ramekins from the water bath and let them cool for a few minutes. Enjoy your custards warm, or chill them in the refrigerator for a firmer texture.
Make It A Meal
This one’s a dessert, so I usually pair it with coffee or tea after dinner. If you’re building out a fall dessert spread, Keto Pumpkin Pound Cake makes a good denser option alongside this lighter custard. For something different in texture, Vanilla Bavarois or Basic New York Cheesecake both round out a dessert table nicely.
Storage
Let the custards cool completely, then cover and refrigerate for up to 4 days. Enjoy cold, or reheat gently in the microwave in short intervals to avoid overcooking. These custards aren’t recommended for freezing, the delicate texture doesn’t hold up well.
FREQUENTLY ASKED QUESTIONS
A water bath surrounds the ramekins with gentle, even heat instead of the direct heat of a dry oven, which is what keeps the eggs in the custard from curdling as they set.
The edges should look set while the center still has a slight jiggle. It will continue to firm up a bit as it cools, so pulling it a touch early is better than overbaking.
No, pumpkin pie filling already has added sugar and spices mixed in, which will throw off both the sweetness and the carb count. Use pure pumpkin puree instead.
Yes, this actually works well made a day ahead. Chill it in the fridge and it firms up into a slightly different, equally good texture by the time you’re ready to serve.

Notes
Recipe Card Tips
- Don’t skip the water bath. Baking the ramekins directly on the oven rack leads to a grainy, slightly curdled texture instead of smooth custard.
- Pull the custards while the center still jiggles slightly. They continue setting as they cool, so a little wobble at the finish line is exactly right.
