Ingredients
Method
- Preheat oven to 350°F (175°C) and line a baking sheet with parchment paper.
- Cream butter and brown sugar until smooth and fluffy.
- Mix in egg and vanilla extract until fully combined.
- In a separate bowl, whisk flour, baking powder, baking soda, salt, and cinnamon.
- Add dry ingredients into wet mixture and mix just until a dough forms.
- Fold in chopped rhubarb carefully without breaking it down too much.
- Scoop dough onto baking sheet, spacing evenly apart.
- Bake for 9–11 minutes until edges are lightly golden.
- Let cool on baking sheet for 5 minutes before transferring to a rack.
Notes
Make sure rhubarb is well drained or the cookies will spread too much. Do not overbake — they should look slightly soft in the center when removed from the oven. Store in an airtight container for up to 4 days.
