Ingredients
- 1/2 cup (1 stick / 113 g) unsalted butter
- 2 cups (400 g) granulated sugar
- 1/2 cup (120 ml) whole milk
- 1/4 cup (60 ml) fresh lemon juice
- Zest of 2 large lemons
- 1 teaspoon (5 ml) vanilla extract
- 1/4 teaspoon (1.25 g) salt
- 3 cups (270 g) quick-cooking rolled oats (do not use instant or steel-cut)
Step-by-step Preparation
- Prepare the Base Mixture: In a medium, heavy-bottomed saucepan, combine the butter, granulated sugar, whole milk, and fresh lemon juice. Place the saucepan over medium heat. Stir constantly until the butter is completely melted and the sugar has dissolved.
- Reach the Critical Boil: Increase the heat slightly and bring the mixture to a rapid, rolling boil—a boil that cannot be stirred down. Start a timer and allow the mixture to boil vigorously for exactly 60 seconds. This crucial step ensures the cookies set properly later.
- Remove and Flavor: Immediately remove the saucepan from the heat. Stir in the vanilla extract, salt, and the fresh lemon zest. Mix thoroughly until the flavors are evenly distributed.
- Incorporate the Oats: Quickly add the 3 cups of quick-cooking rolled oats to the liquid mixture. Work fast, folding the oats into the hot mixture until they are completely coated. The mixture will begin to thicken quickly.
- Scoop and Shape: Working quickly before the mixture hardens, drop heaping tablespoons of the mixture onto sheets of parchment paper or waxed paper. If desired, you can gently shape the drops into neat rounds using the back of a spoon.
- Set and Serve: Allow the cookies to cool completely at room temperature for about 30 to 60 minutes, or until they are firm and set. Do not refrigerate immediately, as rapid cooling can sometimes make them crumbly. Once set, they are ready to enjoy.
Nutritional Information
These Lemon Oatmeal No-Bake Cookies offer a bright dessert option. While they are high in natural sugars, they benefit from the inclusion of rolled oats, which are an excellent source of dietary fiber, promoting digestive health and sustained energy. Each cookie (assuming 24 servings) contains approximately 150-170 calories, a small amount of Vitamin C from the fresh lemon, and a good dose of manganese and phosphorus from the oats. They are also naturally free of eggs and flour, making them suitable for some dietary restrictions.
Storage
Lemon Oatmeal No-Bake Cookies store beautifully. For the best texture and longevity, place the cooled cookies in an airtight container. They can be kept at cool room temperature for up to 3 days, but for maximum freshness and a firmer texture, store them in the refrigerator for up to 7 days. They also freeze well; wrap them individually and store them in a freezer-safe bag for up to 3 months. Thaw at room temperature for 15 minutes before serving.
Conclusion
These Lemon Oatmeal No-Bake Cookies are a perfect balance of creamy sweetness and sharp citrus tang. Serve them alongside a tall glass of iced tea or lemonade for a refreshing afternoon snack. For variations, try adding 1/2 cup of shredded coconut along with the oats for added texture, or drizzle them with a simple lemon glaze (powdered sugar mixed with a splash of lemon juice) once they are fully set. Enjoy this simple, sunny treat!
