In a medium bowl, whisk together 1 1/2 cups of all-purpose flour, 1 tablespoon of ground cinnamon, 2 teaspoons of baking powder, and 1/4 teaspoon of salt until well combined.

In a small bowl, combine 2 tablespoons of instant coffee granules with 2 teaspoons of vanilla extract. Stir well until dissolved.

In a large mixing bowl, beat together 1/2 cup of melted unsalted butter and 1 cup of brown sugar until smooth. Add in one large egg followed by the dissolved coffee mixture.

Gradually add the dry ingredient mixture to the wet ingredients, stirring gently until just combined.

Cover the mixing bowl with plastic wrap and refrigerate the dough for at least 30 minutes.

Once chilled, scoop the dough with a tablespoon and roll into balls. Roll each ball in granulated sugar, followed by powdered sugar.

Preheat your oven to 350°F (175°C). Place the baking sheet with the formed dough balls in the oven and bake for 10-12 minutes.

Remove the cookies from the oven and let cool on the baking sheet for a few minutes before transferring to a wire rack.
