When I made these cookies, I was NOT expecting these Blackberry Cookies to turn out such a gorgeous blue color!
The naturally blue cookies are perfect for a theme party, boys birthday, 4th of July, Smurf recipe, gender reveal party or just to use up a big stash of blackberries!
I started experimenting with pureeing the fruit in these cookies because my kids hate chunks of berries in cookies, cakes and muffins. They can be picky sometimes! Pureeing had the extra benefit of this incredible colour.
When blended blackberries are mixed into cookie dough, they turn purple, then blue-grey after chilling, and then into a bright blue as they react with the baking soda and cook.
The result is a naturally blue cookie that has no artificial colouring or ingredients!

Ingredients
Blackberries - You can use fresh or frozen to give these cookies their beautiful blue colour.
Butter - Adds a rich buttery flavour and texture to the cookies. Or use vegan butter.
Granulated Sugar - Adds sweetness to the cookie dough base.
Vanilla Extract - Infuses a light vanilla flavour throughout.
All-Purpose Flour (plain flour) - Makes up the dry ingredient base of the cookie.
Baking Soda - Helps the cookies rise and reacts to create the blue colour.
Salt - Helps balance all the flavours.
Chocolate Chips - Adds sweet pops of chocolate flavour throughout the blackberry cookies.
Step By Step Tutorial
Follow this step-by-step photo tutorial, then scroll down to the recipe card for the full ingredients list and method.
Thaw the frozen blackberries (or use fresh), either in a pan on the stove or in the microwave, then puree with a handheld immersion blender. Set aside to cool. You should have ½ cup of blackberry puree.
In a medium bowl, cream the butter and sugar with an electric mixer until light and fluffy. Add the blackberry puree and vanilla and beat well.
In a small bowl, whisk together the flour, baking soda, and salt, then add to the blackberry mixture and stir by hand to combine. Fold in the chocolate chips and chill the dough in the fridge for at least 30 minutes.
Roll tablespoonfuls of the dough into balls, place them onto lined cookie sheets, and press down slightly. Bake the cookies at 350F/180C for 8-10 minutes or until the edges are set.
Tips
Although the batter is purple, it turns blue-grey when it’s chilling in the fridge. When the blackberries react with the baking soda they turn blue naturally. The color is consistent inside and out and darkens slightly the next day.
If the cookies are overcooked, the edges might lose a little of the blue color.
Make sure you chill the dough for at least 30 minutes before baking. This will help keep them from spreading and helps the blue color to intensify.
Reserve ¼ of the chocolate chips to place on top for baking for a beautiful blue cookie that’s perfectly studded with chocolate chips.
Don’t overwork the cookie dough or it may change the texture to be a bit tough and chewy.
Serving Suggestions
Serve with a glass of Almond Milk Egg Nog.
Spread the tops with Coconut Whipped Frosting.
Crumble into your favorite Yogurt Parfait for layering. Try layering with plain yogurt and Strawberry Compote to make it a Red White and Blue parfait, perfect for the 4th of July!
Dunk them into a hot cup of Sweet Potato Latte.
Make these blackberry cookies for a cookie exchange.

FAQs
You can! You’ll just have to make sure they are mashed and broken down really well.
Not at all! Believe me, I am surprised at how naturally beautiful they are too!
This is a personal preference. The seeds are not overpowering in the cookies, but you can strain them out if you prefer.

Recipe is good, but I tried twice tonight. Chilling did not change the deep purple color and I didn't double the batch ths time around, nor use a mixer. Not sure where I'm going wrong here. Help!

I put sweeten coconut flakes in as well.
Rolled them into little balls then thumb printed them in the middle. After the cooled I Then added blackberry jam.

They taste very good, but for some reason they where way darker than in your picture and not very blue, more blackish purpleish indigo, its a wierd color.

Hello Kate, thank you for this delicious and colorful recipe. I did not have baking soda, so I used baking powder and this made the cookie purple. Next time, I will definitely use baking soda. thanks again
