A serving is 1/8 of the pie, and the Keebler Graham Cracker crust is 14 carbs per serving while the Diamond pecan crust was 9 carbs per serving. But if I had used a cup of sugar instead of allulose, that would have meant the filling was 30 carbs per serving vs 3 carbs per serving for the one I made using allulose.
A crust made with almond flour might be a little lower in carbs than the pre-made pecan one. (My son does them sous vide in individual jars so they're pre-portioned, but he leaves out the crust completely.)
And if I had made a NY cheesecake in a 10 inch springform pie, it would have had twice as much filling, but with smaller slices that might have pretty much evened out.
