Easy Rhubarb Pudding Cake

Ingredients

• 1 (18.25 ounce) box yellow cake mix
• 1 cup water
• 1/3 cup vegetable oil
• 3 eggs
• 5 cups chopped rhubarb
• 1 cup white sugar
• 1 teaspoon cinnamon
• 1 cup hot water

Directions

Preheat oven to 350 degrees F (175 degrees C). Grease and flour a 9×13-inch baking pan.

Stir cake mix, 1 cup water, vegetable oil, and eggs in a bowl until moistened; beat with an electric mixer on medium speed for 2 minutes. Pour batter into prepared cake pan. Top the batter with rhubarb and sprinkle with sugar and cinnamon; pour 1 cup hot water evenly over the cake.
