In stand mixer, beat sugar and softened butter till creamy, 3-4 min
On low speed, slowly add wet ingredients, one at a time until each is incorporated.
On low, slowly add dry to wet until you have a firm but tacky batter.
Place mixer bowl in fridge for 10 minutes while oven heats.
In small container, shake sugar and cinnamon together.
Using a small scoop, make 2 TBSP size balls of dough. Roll each well in sugar/cinnamon mix. Place 12 on baking sheet equal distance apart. Do not flatten!
Bake one sheet at a time, 375F for 10-11 min or just until edges show slight browning. Remove pan from oven, let cookies sit on pan until next one finishes, 10 min.
Remove cookies onto cooling rack. Try to eat just one, I dare you :)
