Learn how to make the most delicious bat cookies that are perfect for a Halloween dessert! This is a great holiday family baking recipe or Halloween party treat.
Combine and sift together flour, cocoa powder, salt, and baking powder. Set aside.
With hand held mixer or stand mixer, beat soft butter and sugar until light and creamy. Add egg and vanilla extract.
Add sifted ingredients and mix until dough forms. Do not overmix.
Press dough 1/4-inch thick on a cookie sheet lined with plastic food film and place in refrigerator or freezer until firm enough to be rolled, about 20-45 minutes.
Roll dough about 1/8-inch thick on a lightly floured surface. Cut using a bat cookie cutter and place on parchment lined cookies sheets about 1/4-inch apart.
Preheat oven to 350°F. Place in oven and bake until surface is set but is still soft, about 10-11 minutes.
Remove from oven and let cool for a few minutes. Move to a wire rack.
Make the Icing
Combine all of the ingredients in a bowl and beat with a mixer on low speed until smooth and opaque white, about 7 minutes.
If icing is too thick, add more water, 1 teaspoon at a time, until icing has the consistency of glue and you can see the swirl marks from the mixer remain for a few seconds.
You can divide the icing into separate containers and mix in the food coloring if you are using multiple colors – or like me, just add one color and mix. A little food coloring goes a long way!
Apply the Icing
Apply the icing to your bat cookies with a squeeze bottle, or a sandwich bag with the corner cut off. You can use my "design" or make your own.
Use the icing to attach the Reese's bat head as well as the candy eyes. Let set for an hour or so before serving.
