Ingredients
- 60g (2oz or 3/4 cup) gluten-free oat flakes
- 170g (6oz or 1 cup) white chocolate chips
- 1 lemon (zest and juice)
Instructions
- Toast the oats: In a dry skillet over low heat, toast the gluten-free oat flakes for 3-4 minutes, stirring occasionally until they become slightly golden and fragrant. This enhances their flavor and creates a nuttier base for your cookies.
- Melt the chocolate: Place the white chocolate chips in a heat-safe bowl. You can either use a double boiler method or microwave in 30-second intervals, stirring between each until completely melted.
- Infuse with lemon: Once the chocolate is melted, leave the bowl over the warm (but turned off) pan to keep it fluid. Add the zest of one lemon, setting aside a small amount for garnish. Then add half the lemon juice, stirring well to incorporate.
- Add remaining juice: Gradually add the remaining lemon juice while stirring continuously to ensure the mixture doesn’t seize.
- Combine with oats: Pour the lemon-chocolate mixture over the toasted oat flakes and stir thoroughly until all oats are evenly coated.
- Form cookies: Using a moistened tablespoon, scoop portions of the mixture and form into round, flat cookie shapes on a parchment-lined tray.
- Garnish: Sprinkle the reserved lemon zest on top of each cookie for decoration and extra flavor.
- Chill: Place the cookies in the freezer for 15 minutes to set completely.
- Serve: Remove from the freezer and enjoy!

Cooking Tips and Tricks
- Perfect oat toasting: Watch the oats carefully as they toast – they can go from perfectly golden to burnt quickly. Stir frequently and remove from heat as soon as you detect a nutty aroma.
- Chocolate melting hack: If melting the chocolate in the microwave, use 50% power to prevent scorching. Always stop and stir every 30 seconds.
- Lemon juice caution: Add the lemon juice gradually to the white chocolate to prevent it from seizing. If the mixture begins to thicken too much, add a teaspoon of coconut oil to smooth it out.
- Cookie shaping tip: Keep a small bowl of water nearby to moisten your tablespoon between scoops – this prevents the mixture from sticking and helps shape uniform cookies.
- Zest properly: Only zest the yellow part of the lemon peel, avoiding the white pith which can be bitter.
Variations and Substitutions
White Chocolate Alternatives
- Dark or milk chocolate: For a different flavor profile, substitute white chocolate with dark or milk chocolate chips.

Oat Alternatives
- Quick oats: If you don’t have oat flakes, quick oats work well too, though the texture will be slightly different.
- Mixed grains: Try a combination of oats and puffed quinoa for added protein and a varied texture.
Flavor Variations

- Lemon-coconut: Add 2 tablespoons of shredded coconut to the mixture for a tropical twist.
- Lemon-ginger: Incorporate 1/2 teaspoon of ground ginger or 1 teaspoon finely minced candied ginger for a spicy-sweet combination.

Common FAQs
Q: Can I use regular oats instead of gluten-free? A: Absolutely! If you don’t have gluten sensitivity, regular oat flakes work perfectly in this recipe. Just ensure they’re labeled as pure oats if you need them to be truly gluten-free.
Q: Why did my white chocolate seize when I added lemon juice? A: White chocolate can seize when liquid is added too quickly. To prevent this, make sure your chocolate is not too hot and add the lemon juice very gradually while stirring constantly.
Q: How long do these cookies stay fresh? A: When stored properly in an airtight container in the refrigerator, these cookies will stay fresh for up to one week. They can also be frozen for up to a month.
Q: Can I make these cookies vegan? A: Yes! Simply substitute the white chocolate with vegan white chocolate chips. All other ingredients are naturally vegan.
Q: My mixture is too runny to form cookies. What should I do? A: If your mixture is too runny, add more oats, 1 tablespoon at a time, until it reaches a scoopable consistency. Alternatively, refrigerate the mixture for 10-15 minutes before shaping.
Storage and Make-Ahead Tips
- Refrigerator storage: Store cookies in an airtight container in the refrigerator for up to 7 days. Place parchment paper between layers to prevent sticking.
- Freezer storage: These cookies freeze beautifully for up to one month. Place in a freezer-safe container with parchment between layers. Thaw in the refrigerator for 1-2 hours before serving.
- Make-ahead option: Prepare the cookie mixture up to 24 hours in advance and keep refrigerated. Let it soften slightly at room temperature before shaping into cookies.
- Travel tip: For picnics or lunchboxes, freeze the cookies beforehand – they’ll thaw perfectly by snack time while helping keep other foods cool.
- Gift packaging: These cookies make lovely gifts! Stack them in a decorative tin with parchment between layers, and add a ribbon and tag with storage instructions.
