Ingredients:
- For the Cookies:
- 1 cup (2 sticks) unsalted butter, softened
- 1 cup packed light brown sugar
- ½ cup granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 3 cups all-purpose flour
- 1 teaspoon baking soda
- ½ teaspoon salt
- 1 teaspoon ground cinnamon
- ¼ teaspoon ground nutmeg
- For the Rhubarb Filling:
- 2 cups diced fresh rhubarb (about 4 stalks)
- ¼ cup granulated sugar
- 2 tablespoons cornstarch
- 1 tablespoon lemon juice
- ½ teaspoon vanilla extract
- Optional Glaze:
- 1 cup powdered sugar
- 2-3 tablespoons milk or cream
- ½ teaspoon vanilla extract
Preparing the Rhubarb Filling:
Okay, let's start with the rhubarb filling. This needs a little time to cool down, so it's best to get it out of the way first. Don't worry, it's super easy!
- Combine Rhubarb, Sugar, and Cornstarch: In a medium saucepan, combine the diced rhubarb, ¼ cup of granulated sugar, and cornstarch. The cornstarch will help thicken the filling as it cooks. Give it a good stir to make sure everything is evenly coated.
- Add Lemon Juice and Vanilla: Stir in the lemon juice and vanilla extract. The lemon juice adds a nice tang that complements the sweetness of the rhubarb and sugar, and the vanilla just enhances the overall flavor.
- Cook Over Medium Heat: Place the saucepan over medium heat. Cook, stirring frequently, until the rhubarb is softened and the mixture has thickened. This usually takes about 8-10 minutes. You'll notice the rhubarb breaking down and the mixture becoming glossy. Be patient and keep stirring to prevent sticking and burning.
- Cool Completely: Once the filling has thickened, remove it from the heat and let it cool completely. You can transfer it to a bowl and place it in the refrigerator to speed up the cooling process. This is important because you don't want to add warm filling to the cookie dough.
Making the Brown Sugar Cookie Dough:
Now, let's move on to the cookie dough. This is where the magic happens! The brown sugar gives these cookies a wonderful chewy texture and a rich, caramel-like flavor.
- Cream Butter and Sugars: In a large bowl (or the bowl of your stand mixer), cream together the softened butter, brown sugar, and granulated sugar until light and fluffy. This usually takes about 3-5 minutes. Make sure your butter is properly softened, but not melted. You want it to be soft enough to easily cream with the sugars.
- Beat in Eggs and Vanilla: Beat in the eggs one at a time, followed by the vanilla extract. Make sure each egg is fully incorporated before adding the next. The vanilla extract adds a lovely aroma and enhances the other flavors in the cookies.
- Whisk Dry Ingredients: In a separate medium bowl, whisk together the flour, baking soda, salt, cinnamon, and nutmeg. Whisking ensures that the baking soda and spices are evenly distributed throughout the flour, which is important for proper leavening and flavor.
- Gradually Add Dry Ingredients to Wet Ingredients: Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Be careful not to overmix the dough, as this can result in tough cookies. Mix until you no longer see streaks of flour.
- Chill the Dough: Cover the dough with plastic wrap and chill it in the refrigerator for at least 30 minutes. This will help prevent the cookies from spreading too much during baking and will also make the dough easier to handle. You can chill it for longer, even overnight, if you prefer.
Assembling and Baking the Cookies:
Alright, the dough is chilled, the filling is cool, now it's time to put these cookies together and bake them to golden perfection!
- Preheat Oven and Prepare Baking Sheets: Preheat your oven to 375°F (190°C). Line baking sheets with parchment paper. Parchment paper prevents the cookies from sticking and makes cleanup a breeze.
- Scoop Cookie Dough: Scoop rounded tablespoons of cookie dough onto the prepared baking sheets, leaving about 2 inches between each cookie.
- Make Indentations: Use your thumb or the back of a spoon to make a small indentation in the center of each cookie. This will create a well for the rhubarb filling.
- Fill with Rhubarb Filling: Spoon about 1-2 teaspoons of the cooled rhubarb filling into each indentation. Don't overfill the cookies, or the filling might spill out during baking.
- Bake the Cookies: Bake for 10-12 minutes, or until the edges of the cookies are golden brown and the centers are set. Keep a close eye on them, as baking times can vary depending on your oven.
- Cool on Baking Sheets: Remove the baking sheets from the oven and let the cookies cool on the baking sheets for a few minutes before transferring them to a wire rack to cool completely. This will prevent them from breaking apart while they are still warm and soft.
Optional Glaze:
If you want to add a little extra sweetness and visual appeal, you can drizzle these cookies with a simple glaze. It's totally optional, but it does add a nice touch!
- Whisk Together Glaze Ingredients: In a small bowl, whisk together the powdered sugar, milk or cream, and vanilla extract until smooth. Add more milk or cream, one teaspoon at a time, until you reach your desired consistency. You want the glaze to be thin enough to drizzle, but not so thin that it runs right off the cookies.
- Drizzle Over Cooled Cookies: Once the cookies are completely cool, drizzle the glaze over the tops. You can use a spoon, a fork, or a piping bag to drizzle the glaze.
- Let Glaze Set: Let the glaze set for a few minutes before serving. This will allow the glaze to harden slightly and prevent it from being too sticky.
Tips for Perfect Brown Sugar Rhubarb Cookies:
- Use Room Temperature Ingredients: Using room temperature butter and eggs will help the ingredients blend together more easily and create a smoother dough.
- Don't Overmix the Dough: Overmixing the dough can result in tough cookies. Mix until just combined.
- Chill the Dough: Chilling the dough is essential for preventing the cookies from spreading too much during baking.
- Don't Overbake: Overbaking the cookies will make them dry and crumbly. Bake until the edges are golden brown and the centers are set.
- Adjust Sweetness to Taste: If you prefer a less sweet cookie, you can reduce the amount of sugar in the dough or the filling.
- Add Nuts or Chocolate Chips: For an extra layer of flavor and texture, you can add chopped nuts or chocolate chips to the cookie dough.
- Store Properly: Store the cookies in an airtight container at room temperature for up to 3 days.
Variations:
- Strawberry Rhubarb Cookies: Add diced strawberries to the rhubarb filling for a delicious twist.
- Ginger Rhubarb Cookies: Add a teaspoon of ground ginger to the cookie dough for a warm and spicy flavor.
- Lemon Rhubarb Cookies: Add lemon zest to the cookie dough and lemon juice to the rhubarb filling for a bright and citrusy flavor.
