Preheat the oven to 350 degrees Fahrenheit.
In a medium sized mixing bowl, add in the flour and baking powder. Stir the ingredients to combine them.
In the stand mixer, cream the salted butter and sugar together until all of the butter lumps are gone.
Add in the egg and vanilla extract and mix until just combined.
Slowly add the flour and baking powder mixture into the wet ingredients until the dough forms a ball. If the ball is very sticky, add another tablespoon of flour.
Roll the dough onto a floured surface and use the mini heart cookie cutter to cut out the cookies.
Place cookies onto a parchment paper lined cookie sheet and freeze for 10 minutes. Once slightly frozen, insert the cookie sticks about 2/3 of the way into each cookie. You will want to twist the stick into the cookie to get them in. If you accidentally crack the cookies, wait until they soften more then manipulate the dough so that it covers the stick.
Place six cut out cookies onto a cookie sheet lined with a silicone mat or parchment paper. Bake for 10 minutes or until the center of the cookies do not appear wet.
Allow the cookies to cool completely on the baking sheet before frosting.
