Preheat oven to 375 degrees. Line a baking sheet with parchment paper. Set aside.
Cream your butter, sugar, vanilla, blue spirulina powder with a stand or hand mixer on medium-high speed for 5-6 minutes until well mixed.
Add your flour and salt to the butter/sugar mixture, mix on low/medium speed. It will look dry and clumpy if you are using a hand mixer, but if you are using a stand mixer, the dough will come together.
If using a hand mixer, use your hands to clump the dough together so it sticks and forms a ball. Knead it a few times.
Sprinkle in your unicorn chips and knead those in until evenly distributed.
Sprinkle flour on your counter and rolling pin, add the dough and roll out to about ⅜" thick. Cut out in shapes. We used a heart cutter that was 2.5" wide. You can use any shape but do adjust the baking times if using a smaller or larger sized shape.
Place your cut-out shapes onto a parchment lined baking paper about 2 inches apart. Bake for approximately 15 minutes at 375 degrees. Remove, allow to cool on the cookie sheet for several minutes then transfer to a wire baking rack to continue cooling.
