These Lemon Oatmeal No Bake Cookies are bright, chewy, and full of citrus flavor—perfect for a quick treat with no oven required. Made with pantry staples, fresh lemon zest, and oats, they’re a refreshing twist on the classic no-bake cookie. Great for warm weather, quick snacks, and kid-friendly desserts.
Line a baking sheet with parchment paper and set aside.
Make Lemon Syrup:
In a medium saucepan over medium heat, combine butter, sugar, milk, lemon juice, and lemon zest. Stir continuously and bring to a rolling boil. Boil for exactly 1 minute.
Mix Dry Ingredients:
Remove from heat. Stir in oats, shredded coconut, vanilla, and salt. Mix until everything is fully coated and sticky.
Form Cookies:
Drop spoonfuls of the mixture onto the lined baking sheet using a spoon or cookie scoop. Flatten slightly if desired.
Chill and Set:
Let cookies cool at room temperature or refrigerate for 20–30 minutes until set. Drizzle with optional lemon glaze if using.
Notes
Quick oats work best for texture and consistency.
Adjust lemon zest to increase or decrease the citrus flavor.
Cookies will be softer at room temp and firmer if chilled.
For a vegan version, use coconut oil and plant-based milk.
