In a bowl sift together the all-purpose flour, baking powder and salt. Set aside.
Using a mixer with the paddle attachment on medium-high speed, add the sugar, butter and eggs and mix till smooth. If necessary, stop and scrape down the bottom of the mixing bowl to make sure the sugar is dissolved.
Add the vanilla extract and cinnamon in the mixture.
Gradually, add the sifted all-purpose flour, baking powder and salt. Mix on medium speed, till the mixture is formed into a dough.
Remove the cookie dough from the mixing bowl and shape into a disc or two for easier roll out. Cover cookie dough tightly with plastic wrap and chill for 30 minutes.
Remove cookie dough from the refrigerator and allow to sit at room temperature for 10 minutes. This makes the chilled cookie dough easier to roll.
Preheat oven to 350°F (177°C). Line two large baking sheets with parchment paper and set aside.
Roll the cookie dough on lightly floured surface until 1/4 inches thick. Cut with 2- to 2 1/2-inches cookie cutters into desired shapes.
Mix the brown sugar and cinnamon in a ball and sprinkle on top of the cookies. With a spoon press down the sprinkles.
Place the cookies on the lined baking sheets at least 2 inches apart.
Bake for 20 minutes or until edges are lightly brown.
Remove from the oven and let the cookies cool on cooling racks.
Enjoy with a cup of milk or coffee!
