If you’re on TikTok, you may have seen these mesmerizing purple blueberry cookies. When I first saw that trend I immediately decided that I need to try them for myself and see what the hype is all about! I have to say, they did NOT disappoint!

The original TikTok recipe produces deep purple cookies dotted with white chocolate chips made with vegan butter, frozen blueberries and granulated sugar. I thought that for a vegan cookie, these were pretty amazing but I also instantly started figuring out how to make the flavors more balanced and how to make the cookies a little more nutritious.

I absolutely love the lemon blueberry flavor combo so I decided to add lemon juice and lemon zest to the dough. I also experimented with different flours and it turned out that a combination of all purpose and blanched almond flour creates the BEST texture, soft and chewy at the same time. Finally, I didn’t think white chocolate chips add much to the wonderful lemon blueberry flavor perfection so I skipped them all together.

I used frozen Maine wild blueberries in this recipe for two reasons. 1. Because they are my very favorite blueberries to use in baking recipes 2. Maine is my home state so how could I not? If you’ve never tried Maine wild blueberries, go to the grocery store a find a bag of Wyman’s in the freezer aisle. They will blow your mind! My kids eat them frozen as a snack. If you have no access to wild blueberries though, regular bluebs will work great, too!

What's special about this recipe

There are so many reasons to love these purple cookie wonders! The flavor is fantastic, they have the BEST texture and the color is mesmerizing. If that’s not enough to convince you, here are more reasons to believe me:

• This recipe is easy and foolproof! The cookies will turn out perfect every time.
• Intense blueberry flavor in every bite (thanks to blueberries blended into the dough)!
• Great for summer but can be enjoyed all year round thanks to the use of frozen blueberries.
• These cookies are egg free which is great for families with egg allergies!
• They can easily be made vegan (just swap regular butter for vegan butter).
• Kids absolutely love these because they are sweet, soft and, well… purple!

Ingredient notes

• Blueberries: I used frozen wild blueberries from Wyman’s. Regular (farmed) frozen blueberries will also be great.
• All-purpose Flour: I like King Arthur’s.
• Almond flour: use blanched almond flour. I buy mine in bulk at Sam’s Club or online.
• Lemon zest & lemon juice: because blueberry and lemon are a perfect flavor match! Use an organic lemon, if possible and wash the peel well under hot water.
• Sugar: plain old granulated white sugar works best for this recipe.
• Butter: use unsalted good quality butter for that deep flavor and moistness. Vegan butter can be substituted if you want to make vegan blueberry cookies.
• Baking Powder: to help the cookies raise.
• Salt: to balance out the flavors. I use flaky sea salt in baking.

How to make these cookies

STEP 1: Microwave the blueberries. Place frozen blueberries in a small bowl and microwave for about 45 seconds to thaw and warm up. This step will make it easy to mash the blueberries with a fork. They should look mostly smooth, like jam. Add lemon juice and set aside to cool.

STEP 2: Mix dry ingredients. Whisk together all-purpose flour, almond flour, baking powder and salt.

STEP 3: Cream butter and sugar together. I use a standup mixer (my beloved KitchenAid) but you can also do it with a hand mixer. Beat the mixture on medium-high speed until white and fluffy. If using a standup mixer, you may need to stop it and scrape the sides and bottom once.

STEP 4: Add blueberries to the creamed butter sugar and mix together at high speed for about 5 minutes, until the blueberries are completely incorporated and the mixture looks pink.

Note: At first the mixture may look a bit curdled. That’s normal! It will smooth out after a couple minutes.

STEP 5: Add dry ingredients. Stop the mixer and add ⅓ of the flour mixture and all the lemon zest. Mix at low speed until fully incorporated. Repeat with remaining flour in two parts.

STEP 6: Chill the dough. Place the bowl in the freezer for 30 minutes.

Note: I have a chest freezer so I stick the whole KitchenAid bowl in it but if you don’t have much space in the freezer, transfer the dough to a smaller bowl or container.

STEP 7: Roll the sough into 12 balls. I use a small cookie scoop but a spoon will also work. Place cookie dough balls on a cookie sheet lined with parchment paper.

STEP 8: Bake in the oven preheated to 400 degrees Fahrenheit. 10-12 minutes should be enough. The cookies will flatten and the edges will just start browning.

Note: If you prefer flatter cookies, push them gently with the back of a spoon right after you take them out of the oven. If you prefer chunkier, thicker cookies, leave them alone. They are delicious either way!

STEP 9: Let the cookies cool. Place the tray on a cooking rack for at least 15 minutes before diving in!

Tips & tricks for success

Make sure to use softened butter to make the cookie dough. Beat butter and sugar until completely creamed, white and fluffy.

The frozen and warmed up blueberries should be mashed to an almost pureed consistency but they don’t need to be completely smooth. After you add them to creamed butter and sugar, they will blend in nicely. The mixture should be intensely pink after beating it for a couple minutes (see photos above).

When zesting a lemon only use the yellow parts. The white part of the peel is bitter and won’t taste good in the cookies. The best way to zest is by using a microplane but a cheese grater will also work!

Don’t skip the chilling time. The dough will be very soft and the cookies won’t hold their shape during baking time. If you don’t mind flatter cookies, you can shorten the chilling time from 30 to 20 minutes, knowing that they will spread more while baking.

Make cookie dough balls similar size so they bake at the same time. A small cookie scoop does the best job!

Don’t overbake. Take the cookies out after about 10 minutes. The edges should start browning just a little bit.

Storage suggestions

You can store these cookies on the counter for up to 3 days. I don’t put them in an airtight container because the moisture from the blueberries and lemon juice makes them too soft, almost soggy. Instead, you can cover them with a clean thin kitchen towel or parchment paper.

You can also freeze the cookies for up to 3 months in a zip lock bag or a container with a lid. Or, freeze the cookie dough balls for up to 1 month. Let thaw to room temperature before baking.

Variations and substitutions

• To make these cookies vegan, swap regular butter for vegan butter.
• If you don’t have or don’t want to use almond flour, just swap it for equal amount all-purpose flour. They will turn out softer and slightly less chewy (more like muffin stops) but you’ll love them either way!
• If you want, you can fold in ⅓ cup white chocolate chips into the dough.
• To make these cookies gluten free, use gluten free flour in place of all-purpose flour.
