A layer of sweet yeast cake is baked with a gooey, buttery, sweet custard topping in this scratch-made indulgence. All-natural ingredients, pantry staples, no box mix required.
Stir the milk, water, and yeast together in a small bowl, and set aside to proof.
Press the dough into the bottom of an ungreased 9x13-inch baking dish, and set in a warm place to rise until doubled in size (about 2 hours).
Bake in a preheated oven at 350 degrees F for 30 minutes. (Cake should be golden on top but still liquid in the center.)
Cool completely in the pan before cutting into squares.
