How to Make Best Rhubarb Cake with Cake Mix
Ingredients
- 1 box yellow cake mix
- 1 cup rhubarb, chopped
- 1 cup sugar
- 1 cup water
- 1/2 cup vegetable oil
- 3 eggs
- 1 teaspoon vanilla extract
- 1 teaspoon cinnamon (optional)
Directions
- Preheat your oven to 350°F (175°C). This temperature helps achieve that perfectly baked texture while ensuring it doesn’t dry out.
- In a large mixing bowl, combine the yellow cake mix, sugar, water, vegetable oil, eggs, and vanilla extract. Mix well until everything is smoothly blended, which should take about 2-3 minutes of mixing.
- Fold in the chopped rhubarb and cinnamon, if using. Make sure to gently incorporate the rhubarb to avoid breaking it up too much.
- Pour the batter into a greased 9×13 inch baking dish. Use a spatula to spread it evenly, allowing for even baking.
- Bake for 30-35 minutes, checking for doneness by inserting a toothpick into the center. If it comes out clean, it’s ready; if not, put it back for an additional 5 minutes.
- Allow the cake to cool for at least 10-15 minutes before slicing. This will help set the texture and make it easier to serve.
