It was a long time before I realized that "pizookie" was a hybrid term for pizza-cookie. The zoooo-kie part was too distracting to actually sit down and think through the semantics. Plus, it really has little to do with pizza, besides the fact that it was conceived by the BJ's Chicago Pizza and Brewery chain, which has locations all over the West Coast and Southwest, as well as Texas, Florida, and a few Midwestern states. The menu says it all:
You’re never too old to enjoy our freshly baked, hot out of the oven, rich and delicious cookie topped with two scoops of vanilla bean ice cream and served in its own deep dish. Your choice of chocolate chunk, white chocolate macadamia nut, peanut butter, oatmeal raisin walnut, or OREO.
In high school, my friends and I would share pizookies (one was enough for two to three people) at the Laguna Beach location off Pacific Coast Highway. Maybe we ate "real dinner" beforehand, the chain's Chicago-style deep-dish pizza, but maybe we didn't. It was really about waiting for the pizookies. The waitstaff would warn you—it'll take about seven minutes. This factored in enough time for the cookie dough in six-inch pans (the same ones were used for the pizza) to bake just long enough for the outer ring to crispify while the central nucleus remained fluffy and doughy, arguably still in the salmonella-risk zone.
Chocolate chunk ($5.95) is the classic pizookie flavor. As long as every table ordered at least one of those, you could start branching out into the crazies ($5.50).
