Start by preheating the oven to 350 degrees F and grabbing your ingredients. You are going to want an electric mixer with a medium sized bowl and a parchment lined baking sheet.
In your electric mixer bowl, combine the butter and brown sugar, mix well until creamed together. Next, add in the egg.
In a separate bowl, combine the flour and baking powder and then gradually add this to the wet mixture on medium speed until well combined.
Fold in your sprinkles.
Scoop out 2 tbsp sized balls of cookie dough and spread 8-10 evenly on your baking tray. Press the balls of dough down slightly with the bottom of a glass cup, they will still spread slightly.
Bake for 11-12 minutes. Remove from oven and press the hershey kiss in to the center of the cookie. Allow these to cool completely and enjoy!
