How to Make Strawberry Rhubarb Upside Down Cake

  1. Preheat oven to 350°F (175°C).
  2. Melt 1/2 cup (1 stick) unsalted butter in a 9x13 inch baking pan in the preheated oven.
  3. Evenly sprinkle 3/4 cup packed light brown sugar over the melted butter.
  4. Arrange 2 cups sliced strawberries and 2 cups chopped rhubarb evenly over the brown sugar. Gently press them into the sugar.
  5. In a large mixing bowl, prepare your favorite boxed cake mix according to package directions (usually by adding water, oil, and eggs).
  6. Pour the cake batter evenly over the strawberries and rhubarb.
  7. Bake for 45-55 minutes, or until a toothpick inserted into the center comes out clean.
  8. Remove from oven and immediately run a knife or spatula around the edges of the pan to loosen the cake.
  9. Carefully invert the pan onto a large serving plate. Let the pan rest on the cake for 1 minute to allow the brown sugar topping to drizzle down.
  10. Let the cake cool for at least 30 minutes before serving.
  11. Serve warm or at room temperature with a dollop of whipped cream (optional).
