The cream cheese center makes it a bit tricky than other muffins. You can lightly press on the pumpkin muffin portion to test for firmness it should bounce back after pressed. If it doesn't you need to cook longer. You can also insert a toothpick into the pumpkin part of the muffin and if it comes out clean they're cooked. You just need to make sure you don't insert it into the filling as that will remain soft.
