Pecan pie runs about 415 kcal per 100 g. Most of that is sugar and corn syrup, with the pecans and butter carrying the fat. A generous restaurant slice can reach 580, and a scoop of ice cream adds about 140 more.
Approximate values for one standard 115 g slice, including about 29 g of sugar.
Pecan pie calories by portion
Pecan pie is dense, so the slice size matters a lot. The filling is mostly sugar and corn syrup, which is why even a thin sliver adds up fast.
| Portion | Approx. amount | Calories |
|---|---|---|
| Pecan pie | 100 g | ~415 kcal |
| Thin sliver | tenth of a pie, about 95 g | ~395 kcal |
| Standard slice | eighth of a 9 inch pie, about 115 g | ~480 kcal |
| Large restaurant slice | about 140 g | ~580 kcal |
| Slice with a scoop of vanilla ice cream | slice + 60 g ice cream | ~620 kcal |
| Mini pecan tart | about 50 g | ~210 kcal |
Built from pecan pie at about 415 kcal per 100 g, with the filling carrying roughly 29 g of sugar a slice. A scoop of ice cream adds about 140 kcal, a spoon of whipped cream about 50.
Why pecan pie is so calorie dense
- The filling: sugar, corn syrup, eggs and butter. It is basically a set caramel, and almost half the slice is sugar.
- The pecans: nuts are calorie dense even though the fats are the good kind. A pecan heavy pie carries more.
- The crust: a buttery pastry base adds 100 kcal or more before any filling.
- The slice size: a thin sliver and a doorstop restaurant slice can differ by 200 kcal.
A photo calorie app has a hard time here: it cannot tell a thin sliver from a thick slice, and the syrup and butter baked into the filling are invisible. Saying "a big slice of pecan pie with ice cream" gives the estimate a portion and the extras to work with.
“A slice of pecan pie with a scoop of vanilla ice cream.”
Example: Logma logs the pie and the ice cream as two items and lands near 620 kcal with macros, no label reading at the dessert table.

Can you eat pecan pie on a diet
Yes, in a real portion. A standard slice is about 480 kcal, so it is a treat you plan for, not an everyday snack. The trick is one honest slice instead of a thin sliver now and another one later.
- Take one slice and sit down with it, rather than grazing the pan
- Skip the ice cream, or share a scoop, to save 70 to 140 kcal
- Go a size smaller, a tenth of the pie instead of an eighth
- Log it like any other food. One slice inside your calorie deficit is not the problem
4 ways to enjoy pecan pie for fewer calories
- Cut thinner slices: a tenth of the pie instead of an eighth saves about 85 kcal with no one noticing.
- Skip the ice cream: the pie is rich enough on its own, and the scoop is pure extra.
- Share a slice: half a slice plus coffee is a satisfying end to a big meal.
- Bake it lighter: less corn syrup and a thinner crust at home cuts the sugar load.
