Ingredients and Substitutions
Ingredients You’ll Need
- 1 cup (164 g) white chocolate chips
- 2 tablespoons lemon juice
- 2 teaspoons lemon zest
- ½ cup + 2 tablespoons (57 g) quick oats
Ingredient Tips
White Chocolate Chips: Use high-quality chips for the smoothest melt and best flavor. Ghirardelli or Guittard are excellent choices. If you're vegan or dairy-free, look for dairy-free white chocolate alternatives.
Lemon Juice and Zest: Use fresh lemon juice, not bottled. You’ll get a much more vibrant and natural lemon flavor. Zest the lemon before juicing it to make things easier.
Quick Oats: These are thinner and softer than rolled oats, making them ideal for no bake cookies. If you only have rolled oats, pulse them a few times in a food processor to achieve a similar texture.
Substitution Ideas
- Oats: Use shredded unsweetened coconut in place of oats for a tropical twist.
- Lemon: Swap with lime or orange for a different citrus flavor.
- White Chocolate: Vegan white chocolate chips work great if needed. You can also try using a combination of white chocolate and coconut butter for added richness.
How to Make No Bake Lemon Oatmeal Cookies
Step-by-Step Instructions
- Prepare your baking sheet
Line a cookie sheet with parchment paper and set it aside. - Melt the white chocolate
Place the white chocolate chips in a large microwave-safe bowl. Heat them in 15-30 second intervals, stirring between each session until the chocolate is completely melted and smooth. - Add the lemon juice
Once the chocolate is melted, whisk in the lemon juice until fully incorporated. The texture will change slightly and become creamier, almost like a ganache. - Stir in lemon zest and oats
Switch to a spatula and mix in the lemon zest and oats. Stir until everything is evenly combined. The mixture should be thick and sticky, more like a batter than traditional cookie dough. - Scoop and shape
Using a tablespoon-sized cookie scoop or spoon, drop mounds of batter onto your prepared baking sheet. Flatten each cookie into a thick disk using the back of a spoon or your fingers. Smooth out the edges if you like. - Chill to set
Place the cookies in the refrigerator and chill for 30 to 60 minutes until firm. - Serve and enjoy
Let cookies sit at room temperature for 10-15 minutes before eating for the best texture. Or enjoy them straight from the fridge for a firmer bite.
Expert Tips and Tricks
Best Practices
- Zest your lemon first before juicing to make it easier.
- Use dry zest to prevent watery batter.
- Shape while soft because the cookies won’t change shape once chilled.
Common Mistakes
- Overheating the chocolate can make it seize. Stir frequently and stop once just melted.
- Skipping the chill time will leave you with cookies that are too soft to hold.
- Using bottled lemon juice will give the cookies a dull flavor.
Time-Saving Tips
- Make a double batch and store extra cookies in the freezer.
- Pulse rolled oats in bulk and store them for future recipes.
- Use a cookie scoop to portion out cookies quickly and cleanly.

Best Pairings

Presentation Tips

Storage and Reheating
How to Store Leftovers
- Refrigerator: Store cookies in an airtight container in the fridge for up to 1 week.
- Freezer: These cookies freeze beautifully. Place parchment between layers and store in a freezer-safe container for up to 2 months.
Reheating Tips
These cookies don’t need reheating. Just let them come to room temperature if they’ve been in the fridge or freezer. If you like a firmer bite, enjoy them chilled.
Frequently Asked Questions

Absolutely. They’re perfect for making in advance and storing in the fridge or freezer. Just pull them out as needed.
White chocolate can seize if it comes into contact with moisture or gets overheated. Make sure to stir frequently and avoid adding cold lemon juice directly to very hot chocolate.

3 Ingredient No Bake Lemon Oatmeal Cookies

Description
These no bake lemon oatmeal cookies are soft, chewy and full of zesty lemon flavor. They are just three ingredients and very easy to make.
Ingredients
- 1 cup (164 g) white chocolate chips
- 2 tbsp (30 ml) lemon juice + 2 teaspoon lemon zest
- ½ cup + 2 tablespoon (57 g) quick oats
Instructions
- Line a large cookie sheet with parchment paper.
- Add white chocolate chips to a large microwave-safe mixing bowl. Heat chocolate in 15-30 second intervals, stirring in between with a spatula until chocolate is completely melted and smooth. You can also melt the chocolate on the stove using the double boiler method.
- Using a whisk, add in lemon juice and whisk until lemon juice is fully incorporated and the mixture becomes uniform in color and smooth.
- Switch to a spatula and stir in the zest and quick oats until they are evenly mixed in. The batter should be thick.
- Use a 1 tablespoon cookie scoop to scoop up cookie batter and place onto the prepared cookie sheet, spacing cookies 2 inches apart. The batter may spread out a little but it should not spread much. Use the back of a spoon to flatten cookies into a thick round disk (about ¼ inch thick), smoothing edges and top as needed. You can also use your fingers to help shape the edges of the cookies. Cookies will not change shape so shape them to how you would like your final cookies to look like.
- If desired, garnish the top of cookies with additional zest. It will add more lemon flavor and add some color to the cookies. Place cookies into fridge to set. This can take about 30 minutes to one hour. When cookies are set they should feel firm and you should be able to peel the cookies off of the parchment paper. Let cookies sit at room temperature for about 10-15 minutes before eating. You can also eat them straight out of the fridge but the chocolate will be a little more firm when it's cold. Store uneaten cookies in an airtight container in the fridge or freezer.
Notes
You will need approximately 1 large lemon for this recipe. You likely won't need all of the juice and zest it produces. To measure the lemon zest, make sure your zest is mostly dry and then loosely add it to the measuring spoon. Do not pack it in. When measuring out the lemon juice, make sure you strain out any pulp so you have 2 full tablespoon of just lemon juice. There is some flexibility with the amount of quick oats that can be added. If you prefer a sweeter cookie, you can reduce the oats by 2 tbsp. If you want more oat flavor in your cookies, you can increase the quick oats by 2 tbsp. You can make the cookies larger (or smaller) if you wish. I made them smaller than your average cookie because they are very rich.
