Try Angela's in the north part of Manchester. https://angelaspastaandcheese.com/

Or The Kitchen on River Road https://www.thekitchenrr.com/specialty-items

If you go out 101 west you could go past the Black Forest Bakery

Not sure which way you're going, but Tripoli Bakery in Lawrence, MA always has amazing pastries, cakes and pies.

I second Angela's. They have great cream pies and cheese cakes.

Might be a little out of the way depending on what route you take. But Mann Orchards in Methuen, MA just posted on Facebook today about ordering Christmas desserts! Cream pies, cookie pies, and trifles. They also have amazing fruit pies, but they weren’t listed in the post so I’m not sure on their preorder availability

https://www.crosbybakerynh.com/ in Nashua makes good pies, but I would call ahead to make sure they're not sold out.

They sell out FAST

I was just in the Common Man Roadside Market & Deli at 1805 South Willow St in Manchester and they sell Common Man Pies to go! Full size Apple and Pecan were there yesterday.
