Sorry, I was responding to thw apple pie, not dumpling. Also, it needs to be thawed before cooking (if it was frozen).
The recipe calls for 425°f for 40 minutes, spreading syrup over the apples 2 or 3 times until the crust is brown and the applrs are soft when you spear them with a utensil. Um, I've never done one of these answer things before, but I know the recipe by heart. I'm completely certain. I hope this helps.
350°
I bought their Apple pie and they told me to bake for 45 to 1 hour, but I forgot to ask what temp. Google their number and call them.
Sorry you have the wrong number.
