Ingredients
To bake these mouthwatering cookies, you’ll need the following ingredients:
- ½ cup butter, softened
- ¾ cup brown sugar, firmly packed
- ½ cup granulated sugar
- 3 small eggs or 2 large eggs
- 1 tsp vanilla extract
- 1 ¾ cups all-purpose flour
- 1 tsp baking soda
- 1 tsp ground cinnamon
- 3 cups old-fashioned oats
- 3 cups rhubarb, finely chopped
- 1 cup walnuts, chopped
- ½ cup raisins (or more to taste)
- ½ tsp salt
With these items in hand, you’re ready to start this exciting baking adventure.
Cream the Butters and Sugars

First things first, preheat your oven to 375°F (190°C). While that’s heating up, take a large mixing bowl and cream together the softened butter, brown sugar, and granulated sugar until it becomes light and fluffy. This process is essential because it helps incorporate air into the mixture, giving your cookies that delightful texture.
Mix in the Eggs and Vanilla
Next, add in your eggs and vanilla extract to the buttery mixture. Beat everything together until it’s fully incorporated. You want to create a smooth, creamy texture that will be the base for your cookies. Just imagine all that sweetness blending together!
Prepare the Dry Ingredients
In a separate bowl, sift together the all-purpose flour, baking soda, ground cinnamon, and salt. This step ensures that there are no lumps in your flour and helps everything mix together nicely. Stir in the old-fashioned oats until they’re well combined with the dry ingredients. The oats will add that lovely chewiness we want in our cookies.
Combine Wet and Dry Ingredients
Now, it’s time to bring it all together! Gradually add the dry mixture to the wet ingredients. Mix until everything is just combined, taking care not to overmix. Overmixing can lead to tough cookies, and we want these to be soft and tender.
Fold in Rhubarb, Walnuts, and Raisins
Gently fold in the finely chopped rhubarb, walnuts, and raisins until they are evenly distributed throughout the dough. This step is crucial, as you want every bite to include that delightful taste of rhubarb paired with the crunchy walnuts and sweet raisins.
Shape the Cookies
Spoon dollops of cookie dough onto a greased baking sheet. Use the back of a spoon to flatten the mounds slightly because these cookies won’t spread much while baking. So, shaping them is key for achieving that classic cookie shape.
Bake to Perfection
Pop the baking sheet in the oven and bake for 9-12 minutes. Keep an eye on them; you want the edges to be golden brown and just slightly crispy. The aroma that fills your kitchen during this time is simply heavenly—an anticipation of the delicious cookies to come!
Serving Suggestions
Enjoy your cookies while they are still warm, paired with a glass of cold milk or your favorite non-dairy alternative. If you’re feeling adventurous, serve them alongside ice cream for an extra decadent dessert that your family and friends will rave about.
Tips for Success
To ensure the best results with Mom’s Rhubarb Oatmeal Cookies:
- Make sure to chop the rhubarb finely. This helps ensure even distribution throughout the cookies.
- Store any leftover cookies in an airtight container. This will maintain their freshness and chewy texture longer.
Variations
If you’re looking for a twist on the classic recipe, consider these variations:
- Substitute the walnuts with chocolate chips for a sweeter and decadent option that chocolate lovers will adore.
- Try adding coconut flakes to the dough for a tropical flavor that can transport you straight to a summer getaway.
Storage Tips
To keep your cookies fresh and delicious:
- Store them in an airtight container at room temperature for up to a week.
- If you have leftovers, feel free to freeze them in a freezer-safe bag. They can last up to three months, just waiting for that perfect moment to be enjoyed.

FAQs
1. Can I use frozen rhubarb?
Yes, you can! Just make sure to thaw it and drain any excess moisture before adding it to the dough.
