Add the softened butter to a mixing bowl. Add in the light brown sugar and cream together using an electric mixer.
Beat in the remaining wet ingredients until well combined.
Add in the dry ingredients to the wet, making sure to spoon and level the flours.
Beat until combined.
Add the dough to the fridge to set for 30 minutes.
During the final 15 or so minutes, preheat the oven to 350 degrees Fahrenheit.
Use a cookie scoop and roll into even balls, about 1 1/2 tablespoons each. Roll in the cinnamon sugar mixture. Transfer to a baking sheet lined with parchment paper with enough room between each cookie and bake for 10-14 minutes. 11 minutes is usually ideal in my oven, but all ovens are different.
They should look soft in the center when they come out of the oven, but will continue cooking as they cool, so avoid leaving them in for longer if you want them nice and soft.
I always use a round cookie cutter and right after they come out of the oven scoot it around the cookie to create a perfect circle. Let cool on the baking sheet for 15 minutes, then transfer to a wire rack using a spatula to finish cooling.
