Step-by-Step Instructions
Step 1 – Preheat the Oven
Preheat your oven to 375 degrees F (190 degrees C). This ensures even baking for your cookies.
Visual cue: The oven should be hot by the time you’re ready to bake.
Step 2 – Mix the Wet Ingredients
In a large bowl, beat together 1 cup of light brown sugar, 1/2 cup of softened butter, 1 teaspoon of vanilla extract, and 1 large egg using an electric mixer. Mix until it’s smooth and well combined.
Step 3 – Combine Dry Ingredients
Add 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. Beat well until a dough forms.
Step 4 – Fold in the Rhubarb
Lastly, fold in 1 cup of finely diced rhubarb and mix until evenly distributed in the dough.
Step 5 – Scoop the Cookies
Using a 1-inch cookie dough scoop, form balls of dough and place them on a parchment-lined baking sheet. Leave some space between each cookie to allow for spreading.
Step 6 – Bake the Cookies
Bake in the preheated oven for 12-14 minutes or until the cookies are baked through. The edges should be lightly golden.
Step 7 – Cool the Cookies
Let the cookies cool on the baking sheet for about 2 minutes, then transfer them to a wire rack to cool completely.

- Don’t Overbake: Keep an eye on your cookies; they should be slightly underbaked when you take them out for that soft texture.
- Check for Doneness: The cookies should be firm around the edges but still soft in the center when baked.
Flavor Variations
