Preheat oven to 350°F (175°C). Grease a 9x13-inch baking pan or line with parchment with overhang. Make the batter: In a large bowl, whisk together the cake mix, eggs, sour cream, vegetable oil, and 2 teaspoons (10 ml) vanilla until smooth, about 1–2 minutes. Make the cinnamon layer: In a small bowl, mix the brown sugar and cinnamon (stir in nuts if using). Assemble: Spread half of the batter into the prepared pan. Sprinkle the cinnamon-sugar mixture evenly over the batter. Dollop the remaining batter on top in spoonfuls, then use a butter knife to gently swirl the layers together—avoid overmixing so you get ribbons. Bake for 28–33 minutes, or until the top is golden and a toothpick inserted near the center comes out clean or with a few moist crumbs. While the cake bakes, whisk the powdered sugar, milk, 1 teaspoon (5 ml) vanilla, and a pinch of salt until smooth and pourable; add a splash more milk if needed. Glaze: While the cake is still warm (about 5 minutes out of the oven), poke holes all over with a skewer or fork and pour the glaze evenly over the surface. Let set 15–20 minutes. Slice and serve warm or at room temperature.
