1 Preheat the oven to 350°F. Line the bottom of a 9-x-5-inch loaf pan with wax paper, leaving the paper extending beyond the edge of the pan, and spray with vegetable cooking spray. (See Please Release Me.)
2 Following the box’s instructions, combine the cake mix, milk, butter, and eggs in a large bowl. Beat with an electric mixer on low speed until moistened, about 30 seconds. Increase the mixer speed to medium-high and beat, scraping down the sides, until thick, 2 minutes longer.
3 Spread the batter to the edges of the pan and smooth the top. (See Even It Out.) Bake until golden brown and a toothpick inserted in the center comes out clean, 50 to 60 minutes. (See Let’s Get Baked.)
4 Transfer the cake to a wire rack and cool for 10 minutes. Invert, remove the pan, and cool completely.
Pineapple: Prepare the batter and add ¾ cup drained crushed pineapple. Spoon into the prepared pan and bake for 50 to 60 minutes.
Vacuum Cleaner: Prepare the batter and add 1 cup colored cereal O’s (Froot Loops) and 1 cup chopped creme-filled chocolate sandwich cookies (Oreos). Spoon into the prepared pan and bake for 50 to 60 minutes.
