Rhubarb Cake Burger (rhabarberkuchen Burger)

Instructions

1. Preheat the oven to 350°F (175°C). Grease and flour a 9x13 inch baking dish.
2. In a mixing bowl, combine the diced rhubarb and 1/2 cup of sugar. Let it sit for 15 minutes to macerate.
3. In another bowl, cream together the butter and remaining 1 cup of sugar. Beat in the eggs and vanilla extract.
4. In a separate bowl, whisk together the flour, baking powder, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until well combined.
5. Spread half of the batter into the prepared baking dish. Top with the macerated rhubarb, then cover with the remaining batter.
6. Bake in the preheated oven for 40 minutes, or until a toothpick inserted into the center comes out clean.
7. Let the cake cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
8. To assemble the Rhubarb Cake Burgers, slice the cake into 6 equal squares. Place each square between a halved burger bun. Serve with whipped cream or vanilla ice cream if desired.
