A while ago (gauging by the fact that Bug hadn't yet lost any teeth in this picture and now we're down six, it's been several moons), I amped them up a notch: rolled 'em in classic round rainbow sprinkles, paired 'em up, and turned 'em into ice cream sandwiches.
To me, ice cream sandwiches scream summer. We homemade them every year growing up, and that's definitely the kind of tradition I want to continue. With two little kids who ask for "special treat" every single night (and are not often denied), I like to keep the portions under control, and ice cream sandwiches are an easy way to do that. Small cookies + just a tablespoon or two of ice cream = reasonably-sized dessert. In a pinch, I've been known to cut one in half, and they've still never complained.
You can use any flavor combo to personalize your ideal ice cream sandwich. No disrespect to Ben or Jerry, but I think this is the right time for very simple, classic ice cream flavors, particularly if there's a lot going on in the cookie itself. Chocolate, vanilla, and mint-chip all work great. As for cookies, chocolate chip, M&M, and peanut butter are all good choices, but this brownie roll-out cookie really holds up nicely consistency-wise. I would roll these to around 1/4" for the ideal thickness.
Match up the cookies so they're close in size and shape. Soften the ice cream slightly (so it's scoopable, but not starting to get melty). Spoon a small amount onto one cookie, top it with the partner, and squeeze gently to bring the ice cream out to the edges. If you're anal - if, like me, you just like things neat - run a small offset spatula around the ice cream to smooth it out. Wrap individually in plastic wrap, and freeze, then serve them to your kids outside on a warm evening (fewer ice cream drips on the floor). Now if it would only get warmer than 61...
