Chocolate chip rhubarb brownies

A slice of rhubarb brownie dusted with powdered sugar on a small plate.

Chewy, moist, and fudgy brownies with a surprise burst of tart rhubarb in each bite! These are a unique brownie for the rhubarb fans.

Rhubarb and chocolate -- this is a new flavor combination for me. I wasn't sure how rhubarb in brownies was going to turn out, but we were all very happy with the results! I have seen a few recipes out there using this combination (such as here and here) and I was really intrigued.

The more I thought about it, the more I knew we had to make them. The few recipes I saw all said that you couldn't taste the rhubarb, but for me that wasn't the case. The tart flavor of the rhubarb certainly was not overpowering, but I knew it was there and I think that's a good thing. 
The rhubarb in these brownies complimented all the chocolate and sweetness very well and provided a nice contrast in flavor. The addition of chocolate chips also adds extra flavor and texture contrast in these brownies.

Plus, the addition of rhubarb makes these brownies ultra moist and gooey. If you are looking for a new way to enjoy rhubarb, look no further than these chocolate chip rhubarb brownies! I have no doubt the pan will disappear quickly! 
I added a dusting of powdered sugar on top just before serving to make them extra pretty, but this is completely optional. 
This recipe is such a delicious way to enjoy rhubarb and give your brownies a new flavor twist. Serve them at a party or bring them to a picnic and they are sure to be a hit.
Remember when you are cooking or baking with rhubarb, you only use the stalks. Be sure to remove and discard any leaves that are attached as these are not meant to be eaten and can be toxic to humans. The stems are the part that is for eating.

Chocolate Chip Rhubarb Brownies


  • 1 cup sugar
  • 1/2 cup unsalted butter, melted and cooled, plus more for greasing
  • 2 large eggs
  • 1-1/2 teaspoons pure vanilla extract
  • 1/2 cup all-purpose flour
  • 1/3 cup cocoa powder
  • 1/2 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1 cup finely chopped rhubarb
  • 1/2 cup semi-sweet chocolate chips

How to cook Chocolate Chip Rhubarb Brownies

  1. Preheat the oven to 375 degrees. Line an 8"x8" baking dish with parchment paper and lightly butter the top of the paper.
  2. In a medium bowl, whisk together the sugar through vanilla. In a large bowl, whisk together the flour through salt.
  3. Stir the wet ingredients into the dry until just combined. Then fold in the rhubarb and chocolate chips.
  4. Spread the batter evenly in the baking dish. Bake for about 30 minutes, or until an inserted toothpick comes out clean.
  5. Let cool at least 15-10 minutes before slicing. Dust with powdered sugar before serving, if desired.
