Preheat your oven to 350° F. Prepare a large cookie sheet with either non stick spray, a silpat mat, or parchment paper. Set aside.
Blend the flour, baking powder, and salt in a bowl and then set aside.
1½ cups flour, 1½ teaspoon baking powder, ¼ teaspoon salt
In a large mixing bowl, cream the sugar and butter. Add the egg and vanilla mixing well.
½ cup unsalted butter, ¾ cup sugar, 1 egg, 1 teaspoon vanilla or almond extract
Add the dry ingredients to the wet ingredients, mixing well until combined. Scrape sides and pull together into a ball. Divide the ball of cookie dough into three equal amounts.
Place each ball of dough into separate bowls. Add purple gel colorant to one, lime green to another, and orange gel colorant to the third. Mix each bowl well until the colorant is combined well with the cookie dough.
orange gel colorant, lime green gel colorant, purple gel colorant
Take each ball of cookie dough and divide it into 12 smaller balls, all about equal size. Place balls on the cookie sheet in piles of three, one of each color.
After diving all the dough colors, take each pile of three small colored balls and gently roll it to press the three small balls together. Roll in a bowl of Halloween sprinkles. Lay on the cookie sheet about 2" apart.
½ cup Halloween sprinkles blend, candy eyes
Press candy eyes on each cookie. Place in the preheated oven and bake for 12 to 13 minutes.
After baking remove from oven. Let sit 5 minutes, then transfer to a cooling rack.
