1 cup granulated sugar
½ cup packed brown sugar
2 large eggs
2 teaspoons vanilla extract
2 ¾ cups all-purpose flour
1 teaspoon baking soda
½ teaspoon salt

👩‍🍳 Step-by-Step Instructions

1. Preheat Oven

Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper or silicone baking mats.

2. Cream Butter and Sugars

In a large bowl, beat the butter, granulated sugar, and brown sugar with a hand or stand mixer until light and fluffy (about 2–3 minutes).

3. Add Eggs and Vanilla

Mix in the eggs one at a time, then add vanilla extract. Beat until fully incorporated.

4. Whisk Dry Ingredients

In a separate bowl, combine flour, baking soda, and salt. Whisk to blend evenly.

5. Combine Wet and Dry

Gradually add dry ingredients to the wet mixture. Mix just until a soft dough forms.

6. Add Rhubarb

Toss diced rhubarb with cornstarch or flour, then fold gently into the dough using a spatula.

7. Chill the Dough

Refrigerate the dough for 20–30 minutes to firm up. This helps control spreading.

8. Scoop and Bake

Scoop dough into 1½ tablespoon-sized balls and place on prepared baking sheets, spaced about 2 inches apart.
Bake for 10–12 minutes, or until the edges are lightly golden and centers are set.

9. Cool the Cookies

Let cookies cool on the sheet for 5 minutes before transferring to a wire rack.

10. Prepare the Glaze

Whisk together powdered sugar, milk, and vanilla extract until smooth. Add lemon juice if desired.

11. Glaze and Set

Once cookies are completely cool, drizzle glaze over each using a spoon. Let glaze set for 15–20 minutes before storing or serving.

❓ Frequently Asked Questions (FAQs)

❓ Can I use frozen rhubarb?

Yes, but thaw and drain thoroughly to prevent soggy cookies. Pat the rhubarb dry with paper towels before adding it to the dough.
