Reasons to Love these Cookies
- Allergy Friendly- These cookies are gluten free, nut free, egg free and can easily be dairy free (vegan)!
- Soft & Chewy- These cookies are the most perfect texture.
- Covered in Sugar- The sugar coating gives a nice sweetness just like with our Fruity Pebbles Cookies!
- They're Periwinkle!- The real frozen blueberries give the cookies a gorgeous natural periwinkle color and a mild blueberry flavor!
- Gluten Free Flour- If you also have nut allergies, make sure to use a brand that’s made in a nut free facility. I really love to use this gluten free flour because it’s nut safe but it does contain dairy. It also contains xanthan gum which really helps give baked goods their bounce.
- Cornstarch- This little bit of cornstarch mixed into the flour prevents the cookies from spreading. Without it, the cookies will spread out when baking.
- Milk- If there are no dairy allergies or if you’re not vegan, you can use regular whole milk. For non dairy, use a non dairy milk of your choosing.
- Unsalted Butter or Vegan Baking Sticks- Don’t use melted; the cookies will spread into a giant mess.
- Cornstarch and Water- These cookies have no egg so this mixture helps bind everything together.
- Blueberries- I prefer to use frozen because they break down faster in the microwave due to the added moisture.

How to make Blueberry Cookies
Here are the step by step instructions to make these blue cookies!
Step 1: Heat the Frozen Blueberries
In a medium microwave safe bowl, heat the frozen blueberries in 20 second increments, stirring after each time, until they are soft, liquidy and jammy. This took me about 2-2.5 minutes.
Set aside to cool. They will thicken more as they cool.
Step 2: Whisk Together the Dry Ingredients
In a large bowl, whisk together the gluten free flour, baking powder, 1.5 tablespoons of cornstarch and salt. Set aside.
Step 3: Make the Cornstarch Water
In a small bowl, using a spoon, mix together the remaining 2 heaping tablespoons of cornstarch with 3 tablespoons of water until thin and watery. It will be thick and tacky at first.
Step 4: Cream the Sugar
In a large bowl of an electric mixer fitted with the paddle attachment, beat the butter or vegan baking stick and 1 ¼ cups of the sugar until it is soft and creamy. About 2-3 minutes.
Step 5: Add in the other Wet Ingredients
Slowly beat the cornstarch water mixture, milk, the cooled jammy blueberries (about 3 heaping tablespoons...you may have some left over) into the creamed butter and sugar. It will look magenta and chunky.
Step 6: Add in the Dry Ingredients and Chill the Dough
Slowly beat in the gluten free flour mixture a little at a time until just combined.
The dough will be super sticky and lavender.
Keep the dough in the bowl, cover the top with plastic wrap and refrigerate for at least 2.5 hours. You must not skip this step or the cookies will spread everywhere. However, if you chill the dough overnight but it will turn blue instead of lavender with blue flecks.
Step 7: Scoop the Dough and Coat with Sugar
I use an ice cream scoop to make large cookies. It makes 12 scoops.
Roll each dough ball in the extra 2 tablespoons of granulated sugar to coat completely.
Step 8: Bake the Cookies
Place dough balls about 3-4 inches apart on the parchment lined baking sheet. Bake the cookies at 325 degrees Fahrenheit for 15 minutes.
Store extra dough balls in the fridge while the rest are baking if they don't all fit. I only bake 6 at a time.
Immediately reshape the cookies when they come out of the oven by using a spatula to push them into a circle shape and let cool on the baking sheet for 5 min before transferring to a cooling rack. If you don't do this, the cookies will break apart into a giant mess.
Expert Baking Tips
- Use Packed Cups of Flour- Normally in baking we do not use packed cups however, when working with gluten free, I've found using packed cups works best to help the baked goods keep their shape.
- Use Room Temperature Butter- Do not use softened or melted butter/vegan baking sticks. The cookies will spread out when baking into a giant mess.
- Let the Blueberries Cool- Make sure to make the jammy blueberries first so that they have time to chill. You do not want to add hot blueberries into the dough. It will make it way too wet. Ina addition, the jammy blueberries thicken as they cool.
- Do Not Add Vanilla- Adding vanilla turns the dough a grey color instead of lavender.
- Chill the Dough- If you don’t chill the dough for at least 2.5 hours, the cookies will spread and be flat and thin. Chilling overnight is the best.
- Reshape the Cookies- If you want your cookies nice and round, reshape them as soon as they come out of the oven. Use a spatula to push them back into a circle shape.
You can, however, it will change color the longer it sits. Instead of being a lavender with flecks of blue, it will eventually turn completely blue.
If making the dough the night before, keep it shaped in a disc, wrapped in plastic and place in a zip top bag.
If doing this, there is no need to chill it again, prior to baking.
Or you can freeze the dough for up to 30 days. Thaw the dough in the fridge the night prior to using.
Most gluten free baked goods are best made the same day, but you can make these cookies a day before!
Unlike most gluten free/eggless cookies, they’re actually so soft they stay fresh for several days!
Yes! You can use a small cookie scoop.
Bake the cookies at the same temperature but for 13 minutes. Reshape as needed. Should make around 24 cookies.
That is because no food coloring is required to get that amazing hue; it's all natural so the color will be different every time.
The color of the cookies will vary depending on what brand of blueberries you use to make them, how ripe they are and if you used fresh or frozen.
The color is never 100 percent the same, which makes it so fun.
For example, in my Blueberry Cupcakes I used fresh blueberries to make the jam and the frosting came more purple. In my Chocolate Blueberry Cake, I used frozen blueberries to make the jam and it came more magenta.
I used organic wild frozen blueberries to get this periwinkle color.
Once the cookies have cooled, store them in an airtight container at room temperature for up to 3 days.

This cookie was so easy to make and super delicious! Wow! Love the color that popped out!
My grandkids will be visiting soon. Won’t they be surprised to see such pretty cookies. Can’t wait to try this recipe
The color on these is so beautiful! So amazing that it's all natural!
Thanks so so much!
I am French despoiled for my English. I am delighted with her recipes, a favorite, we don't find this in our country.
a blog very detailed, precise photos.
I will do this recipe again and try different ones.
Thank you!!! So kind!
Gave it a go with all purpose flour (not GF). It worked perfectly! I thought it was going to be a very sweet cookie like sugar cookies can be, to my surprise it kind of tasted like if a biscuit, a sugar cookie and blueberries had a baby lol! It was delightful, perfect amount of sweetness. And the color was beautiful! My husband asked if it was ube or blueberry.
So glad it worked out!!!! Thank you!
Could this be made with fresh berries?
Hi Cari! You can mix fresh blueberries in but unless you cook the fresh berries down on the stove into a jam like consistency, you're not going to get this periwinkle color. Hope that makes sense! The frozen are easier due to the high water content; they break down in the microwave very quickly unlike fresh berries.
If I use eggs, do I remove the cornstarch water mixture- how many eggs? Looks great!
Hi! Sadly I cannot test this recipe with eggs due to my son's severe allergy. It actually took me years to try to mimic the texture of a cookie with eggs, so I am not truly sure what adding one would do. If you wanted to try, I would use packed cups of flour (336 grams), no cornstarch water mixture and one egg. Hope it works out! Sorry I can't be of more help!
Thank you! I’ll try that. I recently found out my baby boy has a severe nut & gluten allergy 🙁 I just wanted to say your blog gives me hope that I’ll still be able to bake him some yummy treats as he gets older!
These cookies are Chef’s Kiss perfect! I adjusted the recipe to make them vegan/gluten-free following Lee’s instruction to use gf flour with xanthan gum. The blueberry flavor was subtle. Which made this cookie chewy and versatile. One night friends and I had them with blueberry ice cream. Second night, chilled oat milk flavored with cardamom.
I also made the strawberry version, then mixed both cookie doughs to try both flavors melded. YUMMY!
So happy I found this recipe on Instagram!
Thank you so so much! So glad you like them!!!
I loved these cookies. And so did my kids!! So I used regular frozen blueberries (from Walmart specifically). And I was rather surprised they turned out because I left them in the fridge overnight and didn’t see the part that said if they’re regular and not wild, don’t leave them overnight because it will make the dough watery from the moisture of the berries. Well, I had no issues!! They came out amazing and I didn’t even need to shape the cookies when they came out of the oven. They were already perfectly shaped! Also, the color was beautiful, almost exactly how they look in the photos! 10/10 would recommend and I’m literally obsessed with Lane and Grey Fare!!!!! I’ll buy her book if and when she publishes one!!!
So glad you had zero issues with the dough! Thank you so so much!!!
Been searching for a good blueberry cookie recipe and stumbled upon this beauty, I knew I just had to try it. I used All-purpose Flour and 1 egg instead of the cornstarch-water mixture and these cookies turned out to be one of the most fluffiest, moist, and pretty cookies I've ever made. Decided to add some white chocolate chips on mine, thought ut would be a great pair. Would definitely bake this again!
Thank you so much!!!!
I can’t wait to try these! Do you think I could sub the sugar with stevia? My MIL doesn’t eat sugar and I figured these might be a good option for her!
I haven't tried that but some people have used stevia in my recipes and said it worked! Others have used swerve and monk fruit sweetener. Hope it works out!
