Blue spirulina cookies are a fun and colorful treat that are perfect for any occasion. Whether you're looking for a healthy snack or a unique dessert, these cookies are sure to impress. Here's a detailed and descriptive recipe to help you make your own delicious blue spirulina cookies.

Ingredients:

• 1 cup all-purpose flour
• 1/2 cup unsalted butter, softened
• 1/2 cup granulated sugar
• 1 egg
• 1/2 teaspoon vanilla extract
• 1/2 teaspoon baking powder
• 1/2 teaspoon blue spirulina powder

Instructions:

1. Preheat your oven to 350°F (180°C) and line a baking sheet with parchment paper.

2. In a medium-sized mixing bowl, cream together the softened butter and granulated sugar until light and fluffy.

3. Add in the egg and vanilla extract, and continue to mix until well combined.

4. In a separate bowl, whisk together the flour, baking powder, and blue spirulina powder.

5. Gradually add the dry mixture to the wet mixture and mix until well combined. The dough should be slightly sticky but still firm.

6. Using a tablespoon or cookie scoop, scoop the dough into balls and place them onto the prepared baking sheet, leaving about 2 inches of space between each cookie.

7. Flatten each cookie ball slightly with a fork or the back of a spoon.

8. Bake for 12-15 minutes, or until the edges are slightly golden brown.

9. Remove the cookies from the oven and allow them to cool for 5 minutes on the baking sheet before transferring them to a wire rack to cool completely.

10. Serve and enjoy your delicious blue spirulina cookies!

Optional: You can also add some extra color to your cookies by adding in some white chocolate chips or sprinkles before baking. Simply fold in the chocolate chips or sprinkles with the dough before scooping and baking.
