FAQ

Can I use quick oats instead of old-fashioned oats?

Yes, but old-fashioned oats provide better texture and chewiness. Quick oats will make cookies softer and less textured.

What if my blueberries sink to the bottom?

Toss blueberries lightly in flour before folding into dough. Frozen berries work well and are less likely to burst.

How long do these cookies keep?

Store in airtight container for up to 1 week at room temperature, or freeze baked cookies for up to 3 months.
