Protein-Packed Chocolate Peanut Butter Baked Oatmeal

A hearty breakfast bake that transforms oats into creamy oat flour and combines silken tofu with peanut butter for rich protein content. Sweet maple syrup and vanilla balance the nutty chocolate flavors, while banana adds natural moisture. Perfect for meal prep or feeding a hungry family weekend breakfast. The baked texture is more custard-like than traditional oatmeal, with melted chocolate chips and crunchy peanut pieces throughout.
