First, start by creaming together the butter and sugar in a stand mixer. Add the egg and vanilla extract while continuing to mix.
In a separate bowl, combine the flour, baking powder and salt. Whisk together to break up any lumps.
Pour the flour mixture into the mixing bowl with the wet ingredients about a 1/4 cup at a time while mixing on low speed. Stop to scrape the sides of the bowl as needed.
Preheat the oven to 350 degrees F.
Separate the dough into 2 separate pieces to make it easier to roll out.
Form the dough into the shape of a ball and set it on top of a large piece of parchment paper. Dust the rolling pin with flour and add more flour to it as needed while rolling out the sugar cookie dough. Begin rolling out the ball of dough until it is about a 1/4 of an inch thick.
Use the bat shaped cookie cutter to cut the bat cookies out. Transfer the bats to a baking sheet with parchment paper. Form the remaining dough back into the shape of a ball and roll it out again repeating the same steps until you have used up all of the dough.
Bake the bat sugar cookies for 7-10 minutes at 350 degrees F. You’ll know the cookies are ready once the bottom is a golden color.
Remove from the oven and let them sit in the baking sheet for about 10 minutes before transferring to a cooling rack to finish cooling. Once the cookies have cooled completely, dip them in black icing making sure to let the excess drip off.
Immediately dip them into the black sanding sugar making sure to cover the bats completely. Transfer them back to the cooling rack and dip the bottom part of red cinnamon candies in a little bit of icing. Place them on the bat gently pressing down so they stick. Allow the icing to dry for at least an hour before serving.
