Instructions

Let’s dive into how you can make these delightful no-bake cookies:

Melt the Butter: In a saucepan, melt the butter over medium heat. Add the brown sugar, milk, and a pinch of salt, and stir until everything is fully combined and the mixture begins to bubble.
Simmer the Mixture: Let the mixture come to a gentle boil for about 1-2 minutes, stirring occasionally. This helps to thicken it up.
Add Lemon Flavor: Remove the pan from the heat and stir in the lemon juice, lemon zest, and vanilla extract. The smell will instantly brighten up your kitchen!
Stir in the Oats: Add the rolled oats into the lemon mixture and stir until fully coated. The oats should absorb all that flavorful goodness.
Shape the Cookies: Drop spoonfuls of the oat mixture onto a parchment-lined baking sheet or plate, forming little mounds. You can flatten them slightly if you want them to be more cookie-shaped, or leave them as is for a more rustic look.
Chill & Set: Place the cookies in the fridge and let them set for about 30-60 minutes. The chill time helps them firm up, making them perfect for biting into.
Serve and Enjoy: Once they’ve set, they’re ready to enjoy!
