Ingredients

• 1 box (15.25 oz) yellow or white cake mix
• 3 cups fresh rhubarb, chopped into ½ inch pieces
• 3 large eggs
• ½ cup vegetable oil
• 1 cup granulated sugar
• ½ cup sour cream or plain Greek yogurt
• 1 teaspoon vanilla extract
• Optional: ½ teaspoon ground cinnamon or nutmeg
• Powdered sugar for dusting (optional)

Equipment

• 9×13-inch baking dish or similar size
• Large mixing bowl
• Whisk or electric mixer
• Measuring cups and spoons
• Rubber spatula or wooden spoon
• Knife and cutting board
• Cooling rack
• Oven

Instructions

1. Preheat your oven to 350°F (175°C). Grease your 9×13-inch baking dish with butter or non-stick spray to prevent sticking.
2. Prepare the rhubarb: Wash and chop fresh rhubarb into ½ inch pieces. Set aside.
3. Mix the wet ingredients: In a large bowl, whisk together the eggs, vegetable oil, sour cream (or Greek yogurt), and vanilla extract until smooth and creamy.
4. Add the cake mix and sugar: Gradually add the cake mix and granulated sugar to the wet ingredients. If you want a hint of warmth, also add the optional cinnamon or nutmeg. Stir gently to combine. The batter will be thick.
5. Fold in the rhubarb: Carefully fold the chopped rhubarb into the batter using a spatula. Make sure the rhubarb is evenly distributed but avoid overmixing.
6. Pour the batter into the prepared baking dish: Spread it evenly with a spatula, smoothing the top.
7. Bake: Place the dish in the preheated oven and bake for 45-50 minutes, or until a toothpick inserted into the center comes out clean or with just a few moist crumbs attached.
8. Cool: Remove from the oven and allow the cake to cool in the pan on a wire rack for at least 20 minutes.
9. Serve: Dust the top with powdered sugar if desired, slice, and enjoy warm or at room temperature.

Tips & Variations

“For an extra burst of flavor, toss the rhubarb with a tablespoon of sugar before folding it into the batter. This helps to soften the rhubarb and balance its tartness.”

Use frozen rhubarb: If fresh rhubarb isn’t available, frozen works well. Just thaw and drain excess liquid before using to avoid a soggy cake.

Try different cake mixes: Spice cake, white cake, or even lemon-flavored cake mix can add interesting twists. Lemon enhances the rhubarb’s natural tang, while spice cake adds warmth.

Add a crumb topping: For extra texture, sprinkle a crumb topping made of flour, brown sugar, and cold butter on top before baking.

Make it vegan: Substitute eggs with flax eggs (1 tablespoon ground flaxseed + 3 tablespoons water per egg), use plant-based yogurt, and oil suitable for baking.
