Peanut Butter Cup-Stuffed Cookies

The marriage of chocolate and peanut butter is America's gift to the dessert world. Most countries find the combination strange. We find it essential. H.B. Reese understood this when he created his cups in a basement in Hershey, Pennsylvania in 1928. Nearly a century later, home bakers decided to wrap cookie dough around those cups and see what happened. What happened was magnificent.

This cookie belongs to the stuffed cookie movement that swept through bakeries and home kitchens in the 2010s. Take something already good. Put something else good inside it. Bake until the outside is set and the inside is molten. It sounds simple because it is. The execution requires attention to temperature: the peanut butter cups must be frozen solid before they go into the dough, and the assembled cookies must chill before they meet the oven.

I've watched students rush this recipe and produce puddles of chocolate-peanut butter lava on their sheet pans. Patience rewards you here. A frozen center and a hot oven create the contrast you're after: crackled chocolate exterior giving way to soft, yielding peanut butter that hasn't quite melted away. Each cookie becomes a controlled experiment in thermal dynamics disguised as dessert.

These are make-ahead cookies. The dough freezes beautifully. The assembled, unbaked cookies freeze even better. Your future self will thank you when company arrives unexpectedly and you can produce warm, stuffed cookies in fifteen minutes.
