Fill every other muffin cup (aka only the ones you've lined) about 90% full with the pumpkin batter.
Add the cream cheese filling into a piping bag or a plastic zip top bag. Press the tip of the bag into the center of the muffins, almost all the way to the bottom.
Start squeezing the filling out, while lifting the bag slowly until you reach the top.
Sprinkle the top of each muffin, around the cream cheese center, with the cinnamon sugar pecan mixture.
I only have one jumbo pan so I bake half the batter, leave the rest of the batter in the bowl at room temperature, then bake the remaining batter once the first half has baked.
Place the muffin pan in the hot oven and bake for 8 minutes. After the 8 minutes, turn the oven down to 350 and bake for another 6-8 minutes.
Once baked, take the pan out of the oven. Turn the oven back up to 425 F and leave the freshly baked muffins to cool for 5 minutes before carefully lifting them out of the pan.
Let the pan cool off while the oven turns up, then repeat the assembly process with the remaining pumpkin batter. Bake according to the above instructions.
Allow the muffins to cool for at least 10 minutes once removed from the pan so that you don't burn your mouth on the cream cheese.
Store leftovers in an airtight container either at a cool room temperature or in the fridge!
