Step-by-Step Instructions
1. Prep Your Tray
Start by lining a large cookie sheet with parchment paper. This prevents sticking and makes cleanup a breeze.
2. Melt the White Chocolate
Place your white chocolate chips into a microwave-safe mixing bowl. Heat in 15–30 second intervals, stirring between each session until smooth and glossy. If you prefer, you can melt the chocolate using a double boiler.
3. Add Lemon Juice
Once melted, whisk in the lemon juice. The mixture may seize or thicken slightly that’s totally normal. Just keep whisking until it becomes smooth and uniform in color.
4. Stir in the Zest and Oats
Switch to a spatula and stir in your lemon zest and quick oats. Mix until fully combined. The batter should be thick and fragrant.
5. Scoop and Shape
Use a 1-tablespoon scoop to drop cookie dough onto the prepared sheet. Flatten each into a thick disk (about ¼ inch thick) using the back of a spoon. Shape with your fingers if needed remember, these won’t spread while setting.
6. Chill to Set
Sprinkle with extra zest if desired (highly recommended for an extra citrusy punch). Then, place the tray in the fridge for 30 minutes to 1 hour, or until cookies are firm.
Once set, your 3 Ingredient No Bake Lemon Oatmeal Cookies are ready to enjoy!
Chef’s Tips & Tricks
- Use fresh lemon juice: Bottled juice just doesn’t have the same pop.
- Zest before juicing: It’s much easier this way!
- Adjust sweetness and texture: Want a sweeter cookie? Reduce oats by 2 tbsp. Want more chew and fiber? Add 2 tbsp more oats.
- Shape carefully: Since these cookies don’t bake, shape them exactly how you want the final product to look.
- Storage: Keep in an airtight container in the fridge or freezer. They taste great cold, but I love letting them sit for 10-15 minutes before eating perfect texture!
Variations to Try
