Ingredients for this Zesty Lemon Oatmeal No-Bake Cookies Recipe
- 2 cups rolled oats
- 1/2 cup almond butter (or peanut butter)
- 1/3 cup maple syrup or honey
- Zest from 2 lemons
- Juice from 1 lemon (about 2 tablespoons)
- 1 teaspoon vanilla extract
- 1/2 teaspoon ground cinnamon
- Pinch of sea salt
- Optional: 2 tablespoons shredded coconut
- Optional garnish: powdered sugar and extra lemon zest

Step 1: Mix Wet Ingredients
In a medium mixing bowl, combine the almond butter, maple syrup (or honey), lemon juice, lemon zest, vanilla extract, and a pinch of sea salt. Stir until everything is well incorporated and smooth.
Step 2: Add the Dry Ingredients
Add the rolled oats and ground cinnamon to the bowl. Stir well to ensure all the oats are coated with the lemony mixture. If you’re using shredded coconut, fold it in at this stage.
Step 3: Chill the Mixture
Cover the bowl and place it in the refrigerator for about 30 minutes. This allows the oats to soak in the moisture and firm up slightly, making the mixture easier to handle.
Step 4: Shape the Cookies
Using a spoon or cookie scoop, portion out the mixture and form into small cookie shapes. You can press them flat or leave them slightly mounded, depending on your preference. Place them on a parchment-lined tray.
Step 5: Final Chill
Refrigerate the formed cookies for an additional 30 minutes to set completely. Once firm, they’re ready to enjoy!
Optional Finish:
Before serving, dust with powdered sugar and a sprinkle of fresh lemon zest for extra brightness.
