Preheat oven to 400°
In a large bowl, beat eggs with a fork until well blended together
Stir in oil and vanilla and whisk together
Whisk in the brown sugar
Add baking powder and salt and mix together in egg/oil mixture
Slowly add in the flour and continue whisking to combine.
Dough will be a little runnier/more loose than your average cookie dough
Using a 2-ounce*** ice cream scoop, scoop up the batter and place on a parchment lined cookie sheet with at least 2 inches room to spread out
Once you have all the cookies scooped onto the baking sheets, mix the white sugar and cinnamon in a small, shallow bowl
Spray non-stick cooking spray on the bottom of a heavy bottomed flat drinking glass and dip the bottom of the glass in the cinnamon sugar mixture
Gently pat/press down on the cookie dough until it is a bit more flat. Because you used the non-stick spray, this will leave a lot of sugar and cinnamon behind on the top of the cookie. This is what you want!!
Once all cookies are pressed, sprinkle decorative sprinkles on top
Bake in a 400° oven for 8-10 minutes until browned around the edges.
Allow to cool completely on a baking rack
