Pressure Cooker Chocolate Pudding via Melissa Clark @NYTimes

"Dense, creamy and fudgy, this pudding is meant to be made in a 6- to 8-quart electric pressure cooker like an Instant Pot. You can bake this recipe as one larger pudding or as individual servings. It can be made in a stovetop pressure cooker, by trimming a few minutes off the cooking time, or you can also bake the individual servings in a water bath in the oven. To do so, heat the oven to 300 degrees. Set the filled, uncovered custard cups in a large roasting pan positioned on the oven's center rack. Add hot tap water to the pan, halfway up the sides of cups. Cover the entire pan with foil, and use a fork to prick holes in foil. Bake until edges are lightly set (lifting the foil to check) but the centers are still jiggly – they will set as they cool – 30 to 35 minutes. Featured in: Why Do Cooks Love The Instant Pot?
