Ingredients
For the Rhubarb Cookies:
-
2 ¼ cups all-purpose flour
-
1 tsp baking soda
-
½ tsp baking powder
-
½ tsp salt
-
1 cup (2 sticks) unsalted butter, softened to room temperature
-
1 cup granulated sugar
-
½ cup light brown sugar, packed
-
2 large eggs, at room temperature
-
2 tsp pure vanilla extract
-
1 ½ cups fresh rhubarb, finely diced (about 2-3 medium stalks)
-
1 tbsp all-purpose flour (for tossing with rhubarb)
-
1 cup white chocolate chips
For the Vanilla Glaze (Optional but Recommended):
-
1 cup powdered sugar, sifted
-
2-3 tbsp milk or cream
-
½ tsp pure vanilla extract
-
Pinch of salt
Instructions
Step 1: Prepare the Rhubarb & Dry Ingredients
-
Wash and dry the rhubarb stalks thoroughly. Trim off any leafy ends (note: rhubarb leaves are toxic and must be discarded). Finely dice the stalks into ¼-inch pieces—you should have about 1 ½ cups.
-
In a small bowl, toss the diced rhubarb with 1 tablespoon of flour. This helps absorb excess moisture and prevents the rhubarb from sinking to the bottom of the cookies.
-
In a separate medium bowl, whisk together the 2 ¼ cups flour, baking soda, baking powder, and salt. Set aside.
Step 2: Cream the Butter & Sugars
-
Preheat your oven to 350°F (175°C). Line two large baking sheets with parchment paper or silicone baking mats.
-
In the bowl of a stand mixer fitted with the paddle attachment (or using a large bowl and a hand mixer), cream the softened butter, granulated sugar, and brown sugar together on medium-high speed for 2-3 minutes, until the mixture is light, fluffy, and pale in color.
Step 3: Build the Cookie Dough
-
Add the eggs one at a time, beating well after each addition and scraping down the sides of the bowl as needed. Beat in the vanilla extract.
-
With the mixer on low speed, gradually add the flour mixture, mixing just until the dry ingredients are incorporated and no streaks of flour remain. Do not overmix.
-
Using a rubber spatula, gently fold in the flour-tossed diced rhubarb and the white chocolate chips until evenly distributed. The dough will be thick and slightly sticky.
Step 4: Scoop & Bake
-
Using a medium cookie scoop (about 1.5 tablespoons), drop rounded balls of dough onto the prepared baking sheets, spacing them about 2 inches apart to allow for spreading.
-
Bake one sheet at a time on the center rack for 12-14 minutes. The cookies are done when the edges are lightly golden and the centers look just set. They will still be very soft—this is key for a chewy texture.
-
Remove from the oven and let the cookies cool on the baking sheet for 5 minutes. During this time, they will finish setting. Then, transfer them to a wire rack to cool completely before glazing.
Step 5: Prepare the Vanilla Glaze
-
Once the cookies are completely cool, make the glaze. In a small bowl, whisk together the sifted powdered sugar, 2 tablespoons of milk or cream, vanilla extract, and a tiny pinch of salt.
-
Whisk until completely smooth. The glaze should be thick but pourable. Add an additional teaspoon of milk if it’s too thick.
-
Using a spoon, drizzle the glaze back and forth over the cooled cookies in a zig-zag pattern. Allow the glaze to set for at least 20-30 minutes before stacking or storing.
Baker’s Notes & Tips for Success
-
Rhubarb Prep is Crucial: Ensure your rhubarb is very finely diced. Larger chunks release too much moisture and can create soggy spots in the cookies. A ¼-inch dice is perfect.
-
Don’t Overbake: These cookies rely on a slightly soft center for their wonderful chewy texture. They will look underdone when you take them out—trust the process. The edges should be lightly golden.
-
Room Temperature Matters: Using room temperature eggs and butter is essential for proper emulsification, which creates a uniform, tender cookie crumb.
-
Flour Tossing: Never skip tossing the rhubarb in flour. This simple step is what keeps the vibrant pieces suspended throughout the cookie.
-
Storage: Store completely cooled, glazed cookies in an airtight container at room temperature for up to 3 days. For longer storage, freeze unglazed cookies in a single layer, then transfer to a freezer bag for up to 2 months. Thaw and glaze before serving.
-
Variations:
-
Strawberry-Rhubarb: Fold in ½ cup of finely diced fresh strawberries along with the rhubarb.
-
Lemon Zest: Add the zest of one lemon to the dough for a bright, citrusy note that complements the rhubarb beautifully.
-
Nutty Crunch: Substitute ½ cup of the white chocolate chips with chopped pecans or walnuts.
