1. Preheat the oven to 350° F. Line a large cookie sheet with parchment or a silicone baking mat.

2. Combine the butter with the sugar and beat on medium speed until well creamed together. Add the eggs and vanilla extract. Mix the butter and sugar until the eggs are well beaten.

3. In a separate bowl, combine the remaining dry ingredients. Slowly add into the batter and beat on medium-low speed until well combined and the dough starts to form, then add the sprinkles and finish mixing to incorporate.

4. Divide the dough into 4 equal-sized balls. Leave one bowl uncolored and dye the remaining 3 using colors of your choice. Work the color into the dough with a spatula or by hand.

5. Place all four doughs into a large bowl and lightly mix with a spoon or by hand to create a tie-dye effect. Overmixing will result in the colors blending and forming new colors.

6. Use a medium or large cookie scoop and portion the dough. Roll each ball of dough in granulated sugar or add additional sprinkles and then place each one about 2 inches apart.

7. Bake at 350° F for 10-12 minutes. Allow cookie to cool on the baking sheet for several minutes and then transfer to a wire rack to cool completely.
