Atticus the Baker
We used this recipe (minus the walnuts) and ended up making a few batches. It's a fun recipe to make with kids because the dough gets really thick, close to a play-doh consistency. It's a little easier for them to participate in making the dough balls.
The boys also got to color brown paper bags, which we delivered the cookies in (they were actually in a ziplock bag inside the brown bag, which was necessary, since we had to toss a couple over a fence onto people's stoops).
I'm looking forward to expanding the boy's gifting/helping/serving experience outside of those we already know. But this has been a fun, big part of our holiday celebrations this year.
