Velvety chocolate, silky cream, and a caramelized crackle on top—this keto version of pot de crème tastes like luxury by the spoonful.
The first time I ever tasted a pot de crème, it wasn’t in some little café tucked down a cobblestoned street in France—it was in Louisville, Kentucky. The New Orleans House had a seafood buffet spread that could make you dizzy with choices, everything from escargot to oysters Rockefeller. But as impressive as all that was, it was the dessert bar that stopped me in my tracks. Neat little ramekins lined up like treasures, each holding a rich, glossy chocolate custard capped with a thin caramelized top. One spoonful, and I knew I’d stumbled onto something unforgettable.
That memory has lingered with me all these years. It wasn’t just the taste, though the silky chocolate cream and the crack of burnt sugar were enough to leave anyone swooning. It was the moment—sitting there with my mama, both of us quiet for once, just letting that chocolate melt on our tongues. Sometimes food does more than feed you; it silences the room, takes you someplace else, and for a brief spell, makes the world stop spinning quite so fast. That’s what that pot de crème did for me.
Now, fast forward a few decades and here I am in my own kitchen, stirring cream and chocolate together, chasing that same magic. A true pot de crème is all about contrast—the satin-smooth custard against the delicate crunch of caramelized sugar, the way the cream softens the boldness of chocolate so each bite feels rich yet impossibly light.
Of course, recreating that experience the keto way meant I couldn’t lean on sugar the way that Louisville buffet did years ago. I still wanted the glossy custard, the silky texture, and that irresistible crackle on top. And that’s where a little sweetener called tagatose changes everything…
Why tagatose is perfect for pot de crème (and all your keto sweets)
When it comes to desserts, sugar has always been about more than sweetness. It browns, it caramelizes, and under a torch it turns glossy and brittle, creating that delicate shell you tap with a spoon before sinking into silky custard. Most sugar substitutes fall short here—they may sweeten, but they don’t behave like sugar. Tagatose is different. Because its molecular structure is so similar to sucrose, it reacts to heat almost exactly like sugar does—melting, browning, and hardening into that glassy finish that makes custards and brûlées so irresistible. Tagatose also blends smoothly into the custard itself, giving just the right amount of sweetness without muting the chocolate or leaving a cooling aftertaste. In this recipe, tagatose allows the chocolate to shine, the cream to soften the edges, and each spoonful to taste like something lifted straight from a Parisian pastry case.
How do I store leftovers?
If you’re lucky enough to have a few pots left over, they’ll keep beautifully. Cover each ramekin tightly with plastic wrap and refrigerate for up to 4 days. For longer storage, you can freeze them: wrap each ramekin in plastic wrap, then put them in a freezer storage bag with all the air pressed out. You can freeze them this way for up to 2 months. When ready to serve, thaw overnight in the fridge. If making ahead and freezing, wait to torch the tagatose topping until right before serving—this way you’ll still get that perfect glassy crackle.

Keto Chocolate Custard—Pot de Crème
Ingredients
- 1/4 cup keto powdered sugar
- 5 egg yolks
- 3 ounces sugar free chocolate chips
- 1 1/2 cups heavy cream
- 1 teaspoon vanilla extract
- 6 teaspoons tagatose
Instructions
- Preheat oven to 325°F.
- In a small bowl, whisk the keto powdered sugar into the egg yolks. Set aside
- Microwave the chocolate chips in a small bowl in 10 second intervals until melted. Set aside.
- In a small pan, heat the heavy cream over medium heat. Be careful not to boil or burn the cream.
- When the cream is warm to the touch, remove it from the heat. Use a tablespoon to temper the eggs by slowly whisking in 1 tablespoon of the warm cream into the eggs. Repeat this step 2 more times to fully temper the eggs.
- Add the melted chocolate to the heavy cream and whisk until smooth.
- Slowly add the egg yolks to the cream and whisk until smooth and silky. Add the vanilla extract and whisk again.
- Line the ramekins on a baking sheet with a rim. Carefully fill each ramekin with the custard. They should be about 2/3 full.
- Extend the oven rack so that it is exposed outside of the oven. Carefully place the baking sheet on the rack. Add water to the sheet pan so that the ramekins are halfway covered. This amount will vary depending on the size of your ramekin. Be careful not to get water in the pots.
- Carefully slide the oven rack into the oven. Bake for 25 minutes. The centers should be slightly jiggly when finished. Do not overbake.
- Let the custards chill on the counter for 30 minutes before placing in the refrigerator. Let them cool in the refrigerator for 1 hour and 30 minutes, up to overnight.
- When ready to serve, sprinkle 1 teaspoon of the tagatose on top of the custard. Use a kitchen torch to scorch the crystals until a hard shell is formed.
