• 1 Caramel Apple mini loaf

They make an easy, delicious hostess gift for tonight’s Halloween party — or a pretty great treat to keep for yourself.

$15 per flight

Once they’re gone, they’re gone! 👻🍞 -flights

Did you miss out on ordering for today’s bake? Don’t worry — we baked extra. 🍞

Send us a DM if you’d like to pick up:
• Small Pumpkin Pie Sourdough
• Small Original Sourdough
• A box of our NEW Apple C***r Snickerdoodles 🍎

Available while supplies last!

And don’t forget about Saturday’s bake. A Sourdough Mini-Flight makes a pretty perfect hostess gift for that party you’ve been invited to — three little loaves, plenty to share, and much more interesting than showing up empty-handed. 😉

This is the perfect Sandwhich bread. Soft like Wonderbread but with all the health benefits of real sourdough. This may be my favorite loaf!
