The Charm of Rhubarb in Baking
Rhubarb is one of those ingredients that feels a bit magical. Technically a vegetable, it’s often treated like a fruit because of its naturally tart, fruity flavor. Its bright pink stalks and crisp texture make it perfect for pies, crisps, and — as you’ll soon discover — cookies.
When baked, rhubarb softens beautifully, releasing a subtle tang that cuts through sweetness. That’s what makes these cookies irresistible — each bite gives you a buttery sweetness followed by a refreshing zing of rhubarb.
Ingredients You’ll Need
Here’s what you’ll need to make these soft and delicious rhubarb cookies:
Main Ingredients:
- 1 cup unsalted butter, softened
- 1 cup light brown sugar, packed
- ½ cup granulated sugar
- 2 large eggs
- 2 teaspoons vanilla extract
- 2 ¾ cups all-purpose flour
- 1 teaspoon baking soda
- ½ teaspoon baking powder
- ½ teaspoon salt
- 1 ½ cups fresh rhubarb, finely diced
- 1 tablespoon cornstarch (to coat rhubarb and prevent sogginess)
(Optional: ½ teaspoon cinnamon or a pinch of nutmeg for warmth)
Step-by-Step Instructions
1. Prep the Rhubarb
Trim and dice the rhubarb into small, even pieces (about ¼ inch thick). Toss with cornstarch in a small bowl — this keeps the cookies from becoming too wet during baking.
2. Make the Dough
In a large bowl, beat the softened butter, brown sugar, and granulated sugar together until light and fluffy — about 2 minutes with an electric mixer.
Add eggs one at a time, then mix in vanilla extract.
3. Combine the Dry Ingredients
In a separate bowl, whisk together flour, baking soda, baking powder, salt, and cinnamon (if using). Gradually mix the dry ingredients into the wet until just combined — don’t overmix.
4. Fold in the Rhubarb
Gently fold the coated rhubarb pieces into the dough with a spatula until evenly distributed. The dough should be soft but not sticky.
If it feels too wet, refrigerate for 20–30 minutes before baking.
5. Scoop and Bake
Preheat the oven to 350°F (175°C) and line two baking sheets with parchment paper.
Scoop tablespoon-sized balls of dough onto the prepared sheets, spacing them about 2 inches apart.
Bake for 11–13 minutes, or until the edges are lightly golden but the centers still look soft.
6. Cool and Glaze (Optional)
Let cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
For extra sweetness, drizzle with a simple vanilla glaze made by mixing ½ cup powdered sugar, 1 tablespoon milk, and ¼ teaspoon vanilla extract.

Notes
Tips for Perfect Rhubarb Cookies
- Dice the rhubarb small. Larger chunks can release too much moisture.
- Toss rhubarb in cornstarch. This keeps the cookies from getting soggy.
- Chill the dough. A short chill prevents spreading and creates thicker cookies.
- Use fresh rhubarb. Frozen works too, but thaw and drain it well first.
- Don’t overbake. They should be slightly underdone in the center when you remove them from the oven.
