Lemon Oatmeal Cookies That Are No-Bake Ingredients

Wet Ingredients:

Butter: Provides richness and helps bind the cookie mixture together. Use unsalted butter for better flavor control.
Sugar: Adds sweetness and helps create a smooth, glossy texture. Granulated white sugar works best.
Milk: Helps create a smooth consistency and supports sugar dissolution. Any type of milk can be used.
Lemon Zest: Adds bright, citrusy flavor and aromatic notes. Fresh zest provides the most intense flavor.
Lemon Juice: Enhances tangy flavor and adds moisture to the cookies. Fresh lemon juice recommended.

Dry Ingredients:

Rolled Oats: Primary base for the cookies, providing texture and substance. Old-fashioned oats are ideal.
Vanilla Extract: Adds depth and complements the lemon flavor. Pure vanilla extract gives the best taste.
Salt: Balances sweetness and enhances overall flavor. A small pinch is sufficient.

Glaze Ingredients:

Powdered Sugar: Creates smooth, glossy glaze with a sweet finish. Sifted for best results.
Additional Lemon Zest: Reinforces lemon flavor in the glaze. Adds visual and taste appeal.
Additional Lemon Juice: Thins the glaze and provides tanginess. Helps achieve desired consistency.

Step 1: Prep Your Workspace

Get your baking sheet ready by laying down parchment paper or a silicone mat.

This will help your cookies slide off easily and prevent any sticky situations.

Step 2: Create a Lemon-Kissed Base

In a medium saucepan, start melting your butter over medium heat.

Then add in:

Sugar
Milk
Lemon zest

Bring the mixture to a gentle bubble and let it dance for 1-2 minutes, stirring continuously to prevent burning.

Step 3: Fold in Oatmeal Magic

Pull the pan off the heat and stir in:

Oats
Lemon juice
Vanilla extract
Salt

Mix everything until it becomes a harmonious, fragrant blend that makes your kitchen smell incredible.

Step 4: Shape Delightful Cookies

Use a spoon to scoop out small mounds onto your prepared baking sheet.

Gently flatten each scoop to create perfect cookie shapes.

Let these beauties sit and firm up at room temperature for 30-45 minutes.

Step 5: Craft a Zesty Glaze

In a small bowl, whisk together:

Powdered sugar
Lemon juice
Lemon zest

Keep stirring until the mixture becomes silky smooth and glossy.

Step 6: Finish with Glaze Glamour

Drizzle or dip each cookie into the lemon glaze.

Allow them to set for 15 minutes until the glaze becomes wonderfully crisp.

Your tangy, sweet treats are now ready to devour!

Adjust oat type between quick or old-fashioned oats for desired chewiness and consistency.
Let cookies cool completely on parchment paper to ensure easy removal and clean separation.
Add extra lemon zest or use fresh-squeezed lemon juice for more vibrant, bright citrus notes.
Store in an airtight container at room temperature for up to 5 days, separating layers with wax paper to maintain shape.
Substitute butter with coconut oil and use almond milk for a lactose-free version of these delightful cookies.

Chill Lemon Oatmeal No-Bake Cookies

Store in an airtight container in the refrigerator for up to 5 days. Place wax paper between layers to prevent sticking.
Wrap individual cookies in plastic wrap, then place in a freezer bag. Freeze for up to 3 months for longer storage.
Remove from freezer and let cookies sit at room temperature for 15-20 minutes before serving. Avoid microwaving to maintain texture.
If cookies become slightly soft, chill in the refrigerator for 10-15 minutes to help them firm up and restore their original texture.

Are these cookies healthy?

These cookies offer some nutritional benefits from oats, which provide fiber and minerals. However, they still contain sugar and butter, so enjoy them in moderation as a treat.
