Key Ingredients & Their Roles
- Light Brown Sugar: Provides warmth and richness; for a deeper flavor, try dark brown sugar.
- Butter: Essential for tenderness and richness; ensure it’s at room temperature for easy mixing.
- Egg: Binds the ingredients and adds moisture for a chewy texture.
- Rhubarb: Adds a unique tang; finely dice to ensure even distribution in the dough.
How to Make Brown Sugar Rhubarb Cookies
- Start by preheating your oven to 375 degrees F, letting the warmth fill your kitchen as it sets the stage for baking magic.
- In a large bowl, combine 1 cup of light brown sugar, 1/2 cup of softened butter, 1 teaspoon of vanilla extract, and 1 large egg. Use an electric mixer to create a smooth mixture.
- Gradually stir in 1 3/4 cups of all-purpose flour, 1 teaspoon of cinnamon, 1/2 teaspoon of salt, 1/2 teaspoon of baking soda, and 1/2 teaspoon of baking powder. The dough should form into a soft ball.
- Finally, fold in 1 cup of finely diced rhubarb until evenly distributed. It should smell like a burst of spring!


Pro Tips & Troubleshooting
- When mixing the sugars and butter, ensure they’re well combined. I found that not mixing enough can lead to clumpy cookies.
- A common mistake is overbaking; keep an eye on the cookies toward the end of the baking time. They should be set but slightly soft in the middle.
- For a twist, you can add white chocolate chips or walnuts for added texture and richness.
- If you want to double the recipe, simply follow the same steps — no adjustments needed for cook time.
Storage & Make-Ahead Guide
Store the cookies in an airtight container in the fridge for up to 5 days. They can also be frozen for up to 3 months. Reheat them in an oven at 350 degrees F for about 5 minutes to bring back their delightful softness. During testing, I found that freezing the cookies enhanced their flavors remarkably.
