👩‍🍳 Step-by-Step Instructions

1. Prep & Preheat

  • Preheat oven to 375°F (190°C). Line a baking sheet with parchment.

2. Cream Butter & Sugar

  1. In a large bowl, beat butter and brown sugar until light and fluffy (~3 mins).
  2. Mix in egg and vanilla until smooth.

3. Combine Dry Ingredients

  1. In a separate bowl, whisk flour, cinnamon, baking soda, baking powder, and salt.
  2. Gradually add to wet ingredients, mixing until just combined.

4. Add Rhubarb

  • Gently fold in diced rhubarb (don’t overmix!).

5. Bake

  1. Scoop 1-tbsp balls of dough, spacing 2″ apart on the sheet.
  2. Bake 12-14 mins until edges are golden but centers are still soft.
  3. Cool 2 mins on the sheet, then transfer to a wire rack.

🌟 Pro Tips

🍓 Rhubarb Success:

  • Pat rhubarb dry to prevent excess moisture.
  • Too tart? Toss with 1 tbsp sugar before folding in.

🔥 Baking Secrets:

  • Chill dough 30 mins for thicker cookies (optional).
  • Underbake slightly—they firm up while cooling.

✨ Flavor Twists:

  • Add ½ cup chopped walnuts for crunch.
  • Swap cinnamon for ½ tsp cardamom for a floral note.

❓ FAQs

3. Can I make them gluten-free?

Use GF 1:1 flour blend and ensure other ingredients are GF.

4. How to store leftovers?

  • Room temp: 3 days in an airtight container.
  • Freeze: Up to 2 months (thaw at room temp).

5. Can I reduce the sugar?

Yes, but rhubarb’s tartness may dominate. Try ¾ cup brown sugar.
