Ingredients
Scale
- 1 box cake mix (any flavor: chocolate, yellow, or white)
- 1/2 cup (120 ml) sour cream (or Greek yogurt or dairy-free coconut yogurt as a substitute)
- 1/2 cup (120 ml) vegetable oil (canola or sunflower recommended)
- 3 large eggs (room temperature)
- 1 cup (240 ml) water
- 1 teaspoon vanilla extract (optional)
Instructions
- Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan with butter or non-stick spray and lightly flour it to prevent sticking.
- In a large bowl, combine the box cake mix, sour cream, vegetable oil, eggs, and water. Using an electric mixer on medium speed, beat for 2 minutes until the batter is smooth and creamy. If whisking by hand, whisk for 4-5 minutes to remove lumps.
- Optional: Stir in 1 teaspoon vanilla extract for deeper flavor.
- Pour the batter evenly into the prepared pan and smooth the top with a spatula.
- Bake for 35-40 minutes. Check doneness by inserting a toothpick in the center; it should come out clean or with a few moist crumbs. Bake a few more minutes if needed but avoid overbaking.
- Remove the cake from the oven and let it cool in the pan for 15 minutes, then transfer to a cooling rack to cool completely before frosting.
Notes
Use room temperature eggs for best results. If batter is too thick, add water 1 tablespoon at a time until pourable but not runny. Avoid overmixing to prevent dense cake. Grease and flour pan well or line with parchment paper. For a lighter cake, substitute half the water with club soda. Do not open oven door frequently during baking to avoid sinking.
