Step 1

Combine the butter and sugar in a stand mixer on medium-high speed until light and fluffy.

Step 2

Add the egg and vanilla, then mix on medium until blended. Turn the mixer off.

Step 3

Mix the flour, cinnamon, baking powder, and salt in a separate bowl. Then add it to the mixer.

Step 4

Start on low, mixing the flour into the butter, until a dough forms.

Step 5

Cover the bowl and place it in the refrigerator to chill for approximately 2 hours. The mixture should be firm enough to hold its shape when molded.

Step 6

Preheat the oven to 350 degrees Fahrenheit (175°C) and line a baking sheet with parchment.

Step 7

Portion the cookie dough into 3/4-inch balls. Then roll each ball in the cinnamon sugar, coating well.

Step 8

Place the cookie dough onto the baking sheet, leaving one inch between each cookie.

Step 9

Bake for approximately 10 minutes, or until the edges start to turn brown.

Step 10

Remove the tray from the oven, and allow the cookies to cool slightly.

Step 11

Then, transfer them to a cooling rack to cool them completely.
