Essential Ingredients for Blue Blueberry Cookies

Here’s what you’ll need to make these vibrant cookies at home:

• 1 cup unsalted butter, softened
  (You can substitute with vegan butter or margarine for a dairy-free version.)
• 1 ½ cups granulated sugar
• 2 large eggs
• 1 tsp vanilla extract
• 1 tsp lemon zest (optional, but adds a fresh zing)
• 1–2 drops of blue food coloring (gel or liquid; adjust for desired intensity)
• 2 ¾ cups all-purpose flour
• 1 tsp baking soda
• ½ tsp salt
• 1 ½ cups fresh or frozen blueberries (frozen blueberries will give a stronger color bleed)

Optional Add-ins:

• White chocolate chips for extra sweetness
• A handful of chopped walnuts or almonds for crunch
• A sprinkle of cinnamon for warmth

Step-by-Step Instructions

Step 1: Preheat and Prep
Preheat your oven to 350°F (175°C). Line two cookie sheets with parchment paper and set aside.

Step 2: Cream the Butter and Sugar
In a large mixing bowl, cream the softened butter with the sugar until light and fluffy—this takes about 2–3 minutes using a hand mixer or stand mixer.

Step 3: Add Eggs, Vanilla, and Color
Crack in the eggs one at a time, mixing well after each addition. Add the vanilla extract, lemon zest, and blue food coloring. Mix until the color is evenly distributed.

Step 4: Combine Dry Ingredients
In a separate bowl, whisk together the flour, baking soda, and salt.

Step 5: Mix Wet and Dry
Gradually add the dry ingredients into the wet ingredients. Mix until just combined—don’t overmix or the cookies may turn out tough.

Step 6: Gently Fold in the Blueberries
Using a spatula, fold the blueberries into the dough carefully. If using frozen berries, don’t thaw them—this helps avoid purple streaks. Your dough should now be beautifully blue with berry bits peeking through.

Assembly and Baking Tips

Use a cookie scoop or tablespoon to drop dough onto your prepared cookie sheets, leaving about 2 inches between each. Gently flatten the tops with your fingers or the back of a spoon.

Baking Time: 18–20 minutes or until the edges are slightly golden and the centers are set.
Let cookies cool on the tray for 5 minutes before transferring to a wire rack to cool completely.

Presentation Tip: For a fun finish, press a few extra blueberries or white chocolate chips on top of the cookies before baking. This gives them a bakery-style look.

Storage and Make-Ahead Tips

Room Temperature: Store cooled cookies in an airtight container for up to 4 days.
Refrigerator: For longer storage, keep them in the fridge for up to 1 week.
Freezer: You can freeze baked cookies for up to 3 months. Just thaw at room temperature before serving.

Make-Ahead Dough: You can refrigerate the cookie dough (covered tightly) for up to 48 hours before baking.

FAQs About Blue Blueberry Cookies

Q: Can I use frozen blueberries?
A: Yes! Frozen blueberries are perfect here. Just don’t thaw them before folding them into the dough. This helps prevent the dough from getting too wet and turning purple.

A: The blue food coloring gives them their signature color, especially when mixed with the natural juice of the blueberries. It’s just for fun and doesn’t change the taste!

Q: Are these cookies healthy?
A: While they’re definitely a treat, the blueberries do offer antioxidants, fiber, and vitamin C. For a healthier twist, you can reduce the sugar or use whole wheat flour.
