rhubarb pie with decorated rhubarb slices on top and powdered sugar

Easy Rhubarb Pie Recipe

Homemade rhubarb pie is an easy and delicious dessert combining a vanilla cake batter with small pieces of tart rhubarb - perfect for celebrating the rhubarb season all the way through to late spring and early summer! While the original recipe for rhubarb pie includes a homemade pie crust with a lattice crust, I've combined a standard vanilla cake with a rhubarb mixture.

Ingredients
  

  • 1 cup butter, unsalted, more for greasing the baking dish
  • 1 cup granulated white sugar
  • ½ teaspoon sea salt or kosher salt
  • 1 teaspoon ground cinnamon, high quality
  • 3 large eggs, room temperature
  • 1 ½ cup flour, not GF + 1 teaspoon for rhubarb
  • 1 ½ teaspoon baking powder
  • 8- ounce rhubarb, cut into ¼-inch thick slices
  • 2 teaspoon vanilla extract
  • For Serving, optional
  • 1 tablespoon large coarse brown sugar
  • Confectioners’ sugar

Instructions
 

  • Preheat oven to 375 degrees Fahrenheit.
  • Grease a 10-inch baking dish with butter or olive oil and lightly dust with flour. Set aside.
  • Cream together pieces of butter and sugar on low speed in a large bowl until creamy and smooth (with a handheld mixer).
  • One by one add eggs, beating on low speed again after each addition.
  • Stir in vanilla extract.
  • In a separate bowl combine flour, baking powder, salt, and cinnamon. In batches add the flour mixture to wet ingredients and combine, scraping the bottom of the bowl and sides with a wooden spoon or spatula. Don’t overmix the flour-sugar mixture on increasing the speed.
  • In a small bowl combine 1 teaspoon flour and rhubarb slices. Toss the rhubarb and shake off any excess flour (a small strainer will help with this).
  • Fold the prepared rhubarb into the cake batter.
  • Pour the batter into the prepared cake dish and even out the top with a pastry spatula. Decorate with chopped rhubarb slices gently pressing them into the batter halfway through. Dust with brown sugar. (For decoration: I cut rhubarb stalks into 6 smaller long pieces (about 4 inches) + 4 pieces (1 inch)).
  • Bake for 40-45 minutes or until the top of the cake is golden brown with a light crisp exterior. Test the center of the cake with a toothpick, if it comes out clean, your rhubarb cake is done. Let the cake rest for 5-10 minutes before slicing. Dust with optional confectioners’ sugar. Enjoy!
