3 cups flour
2 tsp. baking powder
1 tsp ground cinnamon
1/2 tsp. salt

Stir flour, baking powder, 1 tsp of cinnamon, and salt together for dough in a bowl; set aside.

Cream butter and brown sugar in a bowl with a mixer until smooth. Add eggs and vanilla; mix until incorporated. With mixer on low speed, add dry ingredients, blending just to incorporate; do not over mix.
